This proposal outlines an extension of the prevailing ERC-20 token standard, introducing a seamlessly integrated revenue-sharing mechanism. It incorporates a suite of interfaces designed to foster fair distribution of revenue among token holders while preserving the essential attributes of ERC-20. Central to this design is the establishment of a communal revenue pool, aggregating revenues from diverse sources. The token, in essence, embodies shares, affording holders the ability to burn their tokens and redeem a proportionate share from the revenue pool. This innovative burning mechanism guarantees that, when the revenue pool is non-empty, the token's value remains at least commensurate with the share of the revenue pool. Additionally, in periodic intervals, token holders can claim a portion of the reward, enriching their engagement and further enhancing the token's utility.
This proposal standardized an Intrinsic RevShare (revenue-sharing) model, allowing users to claim rewards periodically to ensure the efficiency of liquidity. This standard can inherently offer a clear path to long-term benefits for holders with revenue sharing, achieving a more sustainable token model by rewarding holders.
With the inheritance of ERC-20 functionalities, token holders enjoy flexibility in trading tokens on secondary markets, and an optional burning mechanism empowers them to actively contribute to a deflationary economic model while obtaining a proportional share of the revenue pool.
This approach also encourages active participation in open-source initiatives with a sustainable and multifaceted revenue-sharing ecosystem for Intrinsic RevShare token holders.
This standard enables the tokenizing of all kinds of projects with revenue. This EIP introduces a new model for incentivizing contributions to open-source projects. It proposes the distribution of Intrinsic RevShare tokens to active contributors, creating a tangible asset reflecting project involvement.
Notably, it introduces a use case known as Initial Model Offering (IMO). Many open-sourced AI models face a challenge in monetizing their contributions, leading to a lack of motivation for contributors and organizations alike. This proposal seeks to empower open-sourced AI models and organizations by introducing Intrinsic RevShare token. In leveraging the token for IMO, open-sourced AI organizations can conduct fundraisings for essential funds to incentivize the ongoing development of AI models. Moreover, any project utilizing these open-source models contributes to the sustainability of the ecosystem by paying a designated fee to the revenue pool. This fee forms the basis of a revenue-sharing mechanism, allowing Intrinsic RevShare token holders to claim a proportionate share, thereby establishing a systematic and fair distribution mechanism. Importantly, this revenue-sharing feature serves as a guarantee for token holders, fostering long-term revenue benefits and encouraging sustained engagement in the open-source AI community.

Every compliant contract must implement the IERC7641, and ERC-20 interfaces.
The Intrinsic RevShare Token standard includes the following interfaces:
IERC7641:
claimableRevenue view function to calculate the amount of ETH claimable by a token holder at a certain snapshot.claim function for token holder to claim ETH based on the token balance at certain snapshot.snapshot function to snapshot the token balance and the claimable revenue token balance.redeemableOnBurn view function to calculate the amount of ETH redeemable by a token holder upon burn.burn function for token holder to burn tokens and redeem the corresponding amount of revenue token.The AltRevToken extension is OPTIONAL for this standard. This allows the contract to accept other ERC-20 revenue tokens (more than ETH) into the revenue sharing pool.
The AltRevToken extension
claimableERC20 function to calculate the amount of ERC-20 claimable by a token holder at certain snapshot.redeemableERC20OnBurn function to calculate the amount of ERC-20 redeemable by a token holder upon burn.We implement a revenue sharing mechanism wherein any token holder can claim a proportional share from the revenue pool. To ensure regular and transparent revenue distribution, we have incorporated the snapshot method, capturing both the token balance and the associated claimable revenue token balance. Periodic invocation of the snapshot method, corresponding to distinct revenue-sharing processes, is required. During each snapshot, token holders are empowered to claim a proportionate share from the revenue pool, creating a systematic and equitable distribution mechanism for participants.
snapshot interfaceWe specify a snapshot interface to snapshot the token balance and the claimable revenue token balance. This functionality ensures correctness in tracking token holdings, facilitating a transparent record of each token portfolio. Regular invocation of the snapshot function is essential to maintain up-to-date records. The snapshot interface returns a unique snapshotId, allowing access to the corresponding token balance and claimable revenue token balance associated with that specific snapshot. This systematic approach enhances the correctness and reliability of historical data retrieval, providing users with comprehensive insights into their token and revenue token balances at different points in time.
claimableRevenue interfaceWe specify a claimableRevenue interface to calculate the amount of ETH claimable by a token holder at a certain snapshot. We will share the revenue between two consecutive snapshots. As an example in our reference implementation, assuming that the revenue between two snapshots is R, we specify a revenue sharing ratio p, ranging from 0%-100%, and we share the revenue of pR to different token holders according to the token ratio. In this example, the amount of ETH claimable by a token holder with amount tokens at a certain snapshot is pR * amount / totalAmount , where totalAmount denotes the total amount of ERC-7641 token. Noted that the remaining revenue of (1-p)R will be retained in the revenue pool, and we can take out this part of revenue through burning.
claim interfaceWe specify a claim interface for token holder to claim ETH based on the token balance at certain snapshot. Each token holder can only claim revenue at a certain snapshot once, ensuring a fair and transparent distribution mechanism.
We implement a burning mechanism wherein any token holder can burn their tokens to redeem a proportional share from the revenue pool. This mechanism serves as a guarantee, ensuring that the value of the token is consistently greater than or equal to the share of the revenue pool, promoting a fair and balanced system.
redeemableOnBurn interfaceWe specify redeemableOnBurn interface to calculate the amount of ETH redeemable by a token holder upon burn. It is defined as a view function to reduce gas cost. As an example in our reference implementation, the amount of ETH redeemable, i.e., redeemableETH by a token holder with amount of token to burn is
where totalSupply denotes the total supply of ERC-7641 token, and totalRedeemableETH denotes the total amount of ETH in the burning pool.
burn interface:We specify burn interface for token holder to burn tokens and redeem the corresponding amount of revenue token. A token holder can burn at most all tokens it holds. This burning process leads to a reduction in the total token supply, establishing a deflationary economic model. Furthermore, it is important to note that tokens once burned are excluded from participating in any subsequent revenue sharing.
This standard is backward compatible with the ERC-20 as it extends the existing functionality with new interfaces.
The reference implementation includes sample implementations of the interfaces in this standard under contracts/ and corresponding unit tests under test/.
The introduction of the burning mechanism in this standard signifies a shift towards a deflationary economic model, which introduces unique considerations regarding security. One prominent concern involves the potential impact on token liquidity and market dynamics. The continuous reduction in token supply through burning has the potential to affect liquidity levels, potentially leading to increased volatility and susceptibility to price manipulation. It is essential to conduct thorough stress testing and market simulations to assess the resilience of the system under various scenarios.
The extension of AltRevToken with the ability to set up different revenue tokens introduces specific security considerations, primarily centered around the prevention of adding numerous, potentially worthless tokens. The addition of too many spam (worthless) tokens may lead to an increase in gas fees associated with burning and claiming processes. This can result in inefficiencies and higher transaction costs for users, potentially discouraging participation in revenue-sharing activities.
A robust governance model is crucial for the approval and addition of new revenue tokens. Implementing a transparent and community-driven decision-making process ensures that only reputable and valuable tokens are introduced, preventing the inclusion of tokens with little to no utility. This governance process should involve community voting, security audits, and careful consideration of the potential impact on gas fees.
