Stablecoin Payout Addendum
Effective date: September 28, 2026
1. About this Addendum and its dormant status
1.1. Who we are. This Stablecoin Payout Addendum (this "Addendum") is issued by Summer Labs, Inc., a Delaware corporation ("Summer", "we", "us", "our"), with its principal place of business at 2810 N Church St, STE 89812, Wilmington, DE 19802, United States.
1.2. Dormant until activated. The stablecoin payout program described in this Addendum (the "Program") is not offered at launch. This Addendum creates no rights or obligations, and no enrollment is possible, until Summer announces activation of the Program by notice through the Platform, the Creator dashboard, or email (the "Activation Date"). Summer will not activate the Program unless Global Payouts is available to Summer and its Payout Provider supports stablecoin delivery for Global Payouts from Summer's own account; Stripe confirmed Global Payouts in fiat for Summer the week of 2026-09-14, subject to its written answer on funding conditions; stablecoin delivery on Global Payouts has not been confirmed. Summer may activate the Program in some states and not others, may set an Activation Date and later postpone or cancel it, and is under no obligation ever to activate the Program.
1.3. What this Addendum covers. From the Activation Date, this Addendum governs the optional delivery of Program Payments under the Summer Creator Program in the stablecoin USDC to a self-custodied digital asset address. It forms part of, and is incorporated by reference into, the Creator Program Terms. Your participation is also governed by the Summer Games Terms of Service, the Creator Tax Addendum, the Fee and Rates Schedule, and the Network Share Schedule. Nothing in this Addendum applies to the Paid Games lane.
1.4. Order of precedence; dispute resolution and governing law. If this Addendum conflicts with the Creator Program Terms on a matter concerning stablecoin delivery of Payouts, this Addendum controls as to that matter. Any Dispute between you and Summer arising out of or relating to this Stablecoin Payout Addendum is governed by Section 23 (Dispute resolution and arbitration agreement) and Section 24 (Governing law and venue) of the Summer Games Terms of Service, which are incorporated into this Addendum by reference and are not restated here. Those Sections include a mandatory informal resolution period, an agreement to individual arbitration for US Residents with a thirty (30) day right to opt out, a small claims option, a protocol for Coordinated Cases, and class action and jury trial waivers to the extent the law allows. Nothing in this Addendum changes, restates, or adds to those Sections; if any text in this Addendum appears to do so, Sections 23 and 24 of the Summer Games Terms of Service control.
1.5. Defined terms. Capitalized terms not defined here have the meanings given in the Summer Dictionary. In this Addendum: "USDC" means the US dollar-referenced stablecoin known as USD Coin, issued by Circle or its affiliates (the "Issuer"); "Linked Address" means the self-custodied digital asset address you link under Section 4; "Supported Network" means a blockchain network Summer and the Payout Provider designate as supported for the Program, currently [SUPPORTED NETWORKS PLACEHOLDER]; "Payout" means a Program Payment under the Creator Program Terms; "Payout Provider" means Summer's Payout Provider under the Creator Program Terms (currently Stripe, Inc. and its affiliates, including Bridge [CONTRACTING ENTITY TO BE CONFIRMED AT ACTIVATION]), which performs conversion and on-chain transfer for the Program on Summer's instruction; and "Stablecoin Payout" means a Payout delivered in USDC under this Addendum.
1.6. Acceptance. By opting in to the Program after the Activation Date, you agree to this Addendum, including the risk disclosures and acknowledgments in Section 6.
2. What the stablecoin payout option is (and is not)
2.1. A payout delivery election only. The Program is an optional election about how a Payout is delivered. It does not change what a Payout is, how it is earned, or how it is calculated. Every Payout is computed in US dollars under the Creator Program Terms, the Fee and Rates Schedule, and, where applicable, the Network Share Schedule, exactly as if it were paid to your Payout Account.
2.2. Still a Program Payment. Stablecoin Payouts are Program Payments with the character described in Section 5.3 of the Creator Program Terms and in the Creator Tax Addendum: Summer's own obligation to you under the Summer Creator Program, paid from Summer's own funds, in consideration of the license you grant Summer to host, run, distribute and commercialize your Game. Electing stablecoin delivery does not change that character. For US federal tax purposes Summer treats Program Payments as royalties for that license, as the Creator Tax Addendum describes; Section 7 states how that treatment applies to a Stablecoin Payout.
2.3. Summer never holds your crypto. Conversion of the USD Payout amount into USDC and the on-chain transfer to your Linked Address are performed by the Payout Provider. Summer does not custody digital assets for you, does not operate any custody or storage service, is not an exchange, broker, dealer, money transmitter, or digital asset business, and does not buy digital assets from you or sell digital assets to you.
2.4. Not an investment product. The Program is not an investment, savings, or yield product, and nothing about it is investment advice or a recommendation to hold USDC or any digital asset.
2.5. Sparks are unaffected. This Addendum changes nothing about Sparks. Sparks remain the official currency of Summer Games, usable only to acquire Virtual Content and access within Summer Games; they are not a substitute for real currency, do not earn interest, have no equivalent value in real currency, and cannot be exchanged for real currency; and your right to use Sparks remains a limited, revocable license, as set out in Section 8 of the Summer Games Terms of Service and the Summer Dictionary. Sparks cannot be purchased with, sold for, or exchanged for stablecoin or any other digital asset, by anyone. Earned Sparks are a separate instrument; only Earned Sparks that become a Program Payment under the Creator Program Terms can result in a Payout, and only a Payout can be delivered under this Addendum.
3. Eligibility
3.1. Who can enroll. From the Activation Date, the Program is available only to Creators who meet all of the following: (a) you are an individual or a sole proprietor (entities, including LLCs and corporations, are not eligible at Program launch); (b) you are at least 18 years old; (c) you are a resident of the United States and of a state where the Program is offered (the "Supported States"), currently [SUPPORTED STATE LIST]; residents of New York and Hawaii are excluded, and residents of California and Louisiana are excluded until Summer confirms otherwise at activation; (d) you are enrolled in the Summer Creator Program and in good standing under the Creator Program Terms; (e) you have a valid Form W-9 (or, if non-US persons are ever admitted to the Program, a valid Form W-8BEN or W-8BEN-E) on file under the Creator Tax Addendum, which requires those Tax Forms before your first Program Payment; (f) you have a verified Payout Account (bank account) on file under the Creator Program Terms, to which Payouts revert under Section 9; and (g) your standing delivery election under Section 5.4 of the Creator Program Terms is Payout Account delivery, not platform credit; a platform credit election made for a Program Payment before your enrollment controls that Program Payment.
3.2. Provider approval. Enrollment is also subject to approval by the Payout Provider, which may require additional identity verification, and to any eligibility requirements in the Payout Provider's terms. Summer and the Payout Provider may each decline enrollment.
3.3. Continuing eligibility. You must remain eligible at the time of each Stablecoin Payout. If you move to a state that is not a Supported State, cease to be eligible, or fall out of good standing, we will deliver subsequent Payouts in fiat to your Payout Account.
3.4. Changes to eligibility. We may add or remove Supported States, Supported Networks, and eligibility criteria at any time, including in response to legal or regulatory developments or changes to the Payout Provider's product.
4. Enrollment and address linking
4.1. Opt-in through the Creator dashboard. You enroll by opting in through your Creator dashboard (or another flow we designate) and linking exactly one address on a Supported Network as your Linked Address.
4.2. Your address representations. By linking an address you represent and warrant that: (a) the address is yours and is operated only for your own benefit, not for or on behalf of any third party; (b) the address is self-custodied, meaning you hold and control the private keys; (c) the address is not a deposit address at a custodial exchange, a smart contract address that cannot receive USDC on the Supported Network, or an address you do not control; and (d) the address has not been used, and will not be used, for any unlawful purpose.
4.3. Verification. We or the Payout Provider may require you to verify control of the Linked Address, including by micro-transfer confirmation, signed-message verification, or other means, before the first Stablecoin Payout and again at any time.
4.4. Keeping your address current. You are solely responsible for the accuracy of your Linked Address and network selection. Changes to your Linked Address take effect only after re-verification. A Payout initiated before a change is verified will be sent to the Linked Address then on file.
4.5. Default is fiat. Fiat bank payout remains the default. Until your enrollment and address verification are complete, and whenever your election is revoked, suspended, or reverted, Payouts are delivered in fiat under the Creator Program Terms. You may switch back to fiat at any time through the Creator dashboard, effective for Payouts initiated after the change.
5. How stablecoin payouts work
5.1. Computation and conversion. Each Payout is computed in US dollars, gross at the Creator Rate. At the time the Payout is executed, the Payout Provider converts the net USD amount (after any legally required withholding under the Creator Tax Addendum, which is not a Summer fee, and any fees under Section 10) into USDC at the conversion rate applied by the Payout Provider at that time, and transfers the USDC on the Supported Network to your Linked Address.
5.2. Timing. Stablecoin Payouts follow the Payout schedule in the Creator Program Terms. On-chain settlement times depend on network conditions and the Payout Provider, and are not guaranteed.
5.3. Minimums. Minimum Payout amounts, if different for Stablecoin Payouts, are set out in the Fee and Rates Schedule.
5.4. When a payout is complete. A Stablecoin Payout is complete, and Summer's payment obligation for that Payout is fully discharged, when the transfer of USDC to your Linked Address is confirmed on the Supported Network. What happens to the USDC after confirmation (including loss of keys, key compromise, or Issuer or network failure) is outside Summer's control and responsibility.
5.5. Failed transfers. If a transfer fails, is rejected by the network, or cannot be completed, we will retry it or deliver the Payout in fiat to your Payout Account, at our reasonable discretion as to the delivery method only. We defer a Payout only where fiat delivery is not possible because you have no verified Payout Account on file, in which case Section 9.2 applies; where law requires a Payout to be blocked, Section 8.4 applies. A retried or deferred Payout remains a Program Payment owed under the Creator Program Terms, subject only to the forfeiture grounds listed there. A transfer that is confirmed on-chain to the address you supplied is not a failed transfer, even if you supplied the wrong address.
6. Risk disclosures and your acknowledgments
Read this section carefully. By opting in to the Program you acknowledge and accept each of the following.
6.1. USDC is not legal tender. USDC is a digital asset issued by the Issuer, a third party unrelated to Summer. It is not legal tender, is not issued or backed by any government, and is not a substitute for US dollars. Summer will activate the Program only with a stablecoin whose Issuer is, at the Activation Date, a permitted payment stablecoin issuer under the GENIUS Act (Public Law 119-27) if that Act's restriction on who may issue a payment stablecoin is then in force, and the activation notice under Section 1.2 will state the Issuer's status under that Act.
6.2. Not insured; not a deposit. USDC held at your Linked Address is not a bank deposit or a securities account. It is not insured or guaranteed by the Federal Deposit Insurance Corporation, the Securities Investor Protection Corporation, or any other government agency or insurance program. Summer and the Payout Provider are not banks.
6.3. No yield. Neither Summer nor the Payout Provider pays you interest, yield, rewards, or any other return on USDC delivered under the Program.
6.4. Transfers are irreversible. On-chain transfers of USDC are final. They cannot be reversed, recalled, canceled, or charged back. If a Payout is sent to a wrong, mistyped, inaccessible, or incompatible address that you supplied, or on a network your Linked Address does not support because of your network selection, the USDC will likely be permanently lost. You bear all wrong-address and wrong-network risk, and Summer has no obligation to attempt or fund any recovery.
6.5. Depeg and market risk. USDC is designed to maintain a value of one US dollar, but its market price can and does deviate from one dollar, including materially and for extended periods. Whether USDC can be converted back into dollars depends on the Issuer and its reserves. If the Issuer fails, suspends conversion into dollars, or becomes insolvent, USDC may lose some or all of its value. You bear all risk of change in the value of USDC from the moment of on-chain confirmation, and any conversion spread or movement between computation and conversion is handled by the Payout Provider under its terms.
6.6. Network risk. Blockchain networks can suffer congestion, outages, forks, protocol changes, consensus attacks, and smart contract defects. These can delay, prevent, or alter transfers. Summer does not control any blockchain network and does not support forked or airdropped assets; if a Supported Network forks, Summer and the Payout Provider will determine which chain, if any, remains supported.
6.7. Self-custody risk. You alone control the private keys to your Linked Address. If you lose your keys, seed phrase, or key device, or if your keys are compromised by malware or phishing, your USDC may be permanently lost. There is no password reset and no customer support that can restore access. Neither Summer nor the Payout Provider can access, freeze, or recover assets at a self-custodied address.
6.8. Regulatory risk. The legal treatment of stablecoins is evolving. Changes in federal or state law, regulatory action, or changes to the Payout Provider's licenses or products may require Summer to change, suspend, geo-restrict, or terminate the Program at any time, including with immediate effect.
6.9. Tax complexity. Receiving and later disposing of USDC has tax consequences described in Section 7, which may be more complex than receiving fiat.
6.10. Your own decision. You opt in based on your own judgment. Neither Summer nor the Payout Provider has advised you to receive Payouts in USDC.
7. Valuation, taxes, and reporting
7.1. USD value at transfer time. For all purposes, including tax reporting, our books and records, and any dispute, the amount of a Stablecoin Payout is its US dollar value at the time of transfer, as determined by the conversion executed by the Payout Provider under Section 5.1. That USD amount, not the later market value of the USDC, is the gross Program Payment amount, before any withholding, reported under the Creator Tax Addendum: for US Creators on Form 1099-MISC (royalties) where the IRS reporting threshold is met, and, if non-US Creators are ever admitted to the Program, on Form 1042-S, each as described in Section 7 (Tax reporting) of the Creator Tax Addendum.
7.2. Withholding first, then conversion. Any US withholding required under the Creator Tax Addendum is applied to the gross USD Payout amount before conversion, and only the net amount is converted and transferred. Under that Addendum: (a) if you are a US Creator and no valid Form W-9 is on file, 24 percent backup withholding applies; (b) if non-US persons are ever admitted to the Program, withholding at 30 percent, reduced to the applicable treaty rate where your Form W-8BEN or W-8BEN-E makes a valid treaty claim, applies to the US-Source Share only (the part of your Payout that arose from spends by Players whose Player Country at the time of spend was the United States), and no US withholding applies to earnings from Players outside the United States; and (c) the Withholding Determination recorded in the Creator Tax Addendum governs whether and how much is withheld on the date of a Payout. Withheld amounts are not a Summer fee; Summer remits them to the IRS. US-Source Share, Player Country, Withholding Determination and Tax Forms have the meanings given in the Summer Dictionary.
7.3. Your basis and later gains or losses. Your tax basis in the USDC you receive generally equals the USD value at transfer under Section 7.1. Any gain or loss when you later sell, convert, spend, or otherwise dispose of the USDC is solely your responsibility to track and report. Summer does not track your disposals and does not issue disposal reporting.
7.4. Statements. We or the Payout Provider will make available a record of each Stablecoin Payout showing the gross USD amount at the Creator Rate, any withholding under Section 7.2, the net USD amount converted, the USDC amount, the Supported Network, the destination address, and the transaction identifier.
7.5. No tax advice. Section 10 (No tax advice) of the Creator Tax Addendum applies to this Addendum.
8. Sanctions and compliance screening
8.1. Your consent to screening. You consent to screening, at enrollment and on an ongoing basis including before each Stablecoin Payout, of: (a) your identity, against sanctions and watch lists administered by the US Office of Foreign Assets Control and other applicable authorities; and (b) your Linked Address and its transaction history, using blockchain analytics providers engaged by Summer or the Payout Provider. Screening data is handled consistent with the Summer Games Privacy Policy and the US State Privacy Addendum.
8.2. Risk signals. If screening identifies risk signals associated with your Linked Address (for example, exposure to sanctioned addresses, mixing or tumbling services, darknet markets, ransomware, or stolen funds), Summer and the Payout Provider may refuse or delay a Stablecoin Payout, unlink the address, revert your Payouts to fiat, suspend your Program enrollment, review your Account, and make reports to authorities where required by law.
8.3. Your representations. You represent that you are not a sanctioned person, are not located in or ordinarily resident in any embargoed jurisdiction, and do not operate your Linked Address for or on behalf of any sanctioned person.
8.4. Blocked payouts. Where law requires a Payout to be blocked or rejected, Summer will comply, and blocked amounts will be handled as the law requires. Summer is not liable for amounts it is legally required to block, reject, or report.
9. Summer's right to revert any payout to fiat
9.1. Reversion right. Summer may deliver any Payout in fiat to your Payout Account instead of in USDC, at its discretion and without prior notice, including when: screening under Section 8 flags a risk; a Supported Network or the Payout Provider's stablecoin product is unavailable, degraded, or discontinued; the transfer would create legal or regulatory risk; we suspect error or fraud; your Linked Address cannot be verified; or the Program is suspended or terminated. Reverting a Payout to fiat is not a breach of this Addendum or the Creator Program Terms.
9.2. No Payout Account. If a Payout is reverted to fiat and you have no verified Payout Account on file, the Payout will remain pending, without interest, until you provide one. Pending amounts remain Summer's own funds; nothing is held for you, and Section 13 of the Creator Program Terms (dormancy and unclaimed amounts) applies.
10. Fees
10.1. Fees for the Program, including any Program fee [FEE PLACEHOLDER], network (gas) fees, and Payout Provider conversion or transfer fees, are set out in the Fee and Rates Schedule and are disclosed before you opt in. Fees may be deducted from the Payout before conversion. Fee changes are made with notice as described in the Creator Program Terms.
11. Program changes, suspension, and termination
11.1. The Program depends on a third-party product. The Program is built on stablecoin payout products of the Payout Provider. If the Payout Provider changes, suspends, or discontinues those products or their terms, Summer may make corresponding changes to this Addendum and the Program, including with immediate effect where the underlying change is immediate.
11.2. Changes to this Addendum. We may amend this Addendum as described in the Creator Program Terms. For material changes not required by law or by the Payout Provider, we will give you advance notice, and your continued Program enrollment after the change takes effect is acceptance. You can always decline a change by reverting to fiat payouts.
11.3. Suspension or termination by Summer. We may suspend or terminate the Program, in whole, for specific states, or for specific Creators, at any time. On termination, all pending and future Payouts are delivered in fiat under the Creator Program Terms. Termination of the Program does not affect Payouts already confirmed on-chain.
11.4. Opt-out by you. You may leave the Program at any time through the Creator dashboard, effective for Payouts initiated after the change.
12. Payout Provider terms
12.1. Flow-down. Your use of the Program is conditioned on your acceptance of any additional stablecoin terms the Payout Provider requires Summer to present during enrollment. Those terms govern the mechanics of conversion, custody during transit, and on-chain transfer; this Addendum governs your relationship with Summer. You do not open an account with the Payout Provider, and the Payout Provider owes you no obligation under this Addendum.
12.2. Independent providers. The Payout Provider and the Issuer are independent third parties, not agents of Summer beyond executing Payout instructions. To the maximum extent permitted by law, Summer is not responsible for their acts, omissions, insolvency, or product changes, and any claim you have against the Payout Provider or the Issuer is subject to their respective terms.
13. Disclaimers and limitation of liability
13.1. As-is program. To the maximum extent permitted by law, the Program is provided as is and as available, and Summer disclaims all warranties regarding the Program, blockchain networks, key-management software, the Issuer, USDC, and its value, whether express, implied, statutory, or otherwise.
13.2. Liability limits. The limitations of liability and the dispute resolution provisions in the Summer Games Terms of Service and the Creator Program Terms apply to this Addendum. Without limiting them: Summer's payment obligation for a Stablecoin Payout is fully discharged as described in Section 5.4; Summer is not liable for losses caused by an address or network you supplied, by your loss of private keys, by USDC value fluctuation, by Issuer failure, or by network events described in Section 6.6.
13.3. Non-waivable rights. Nothing in this Addendum limits or excludes liability that cannot be limited or excluded under applicable law, or waives rights you have under consumer protection law that cannot be waived.
14. Relationship to other documents
14.1. This Addendum is part of the Creator Program Terms and is subject to the Summer Games Terms of Service (including Sections 23 and 24 as incorporated by Section 1.4), the Creator Tax Addendum, the Fee and Rates Schedule, and the Network Share Schedule. The Refund and Billing Policy governs Player purchases of Sparks and is unaffected by this Addendum.
