A Beginner’s Guide to EIP-5725: Transferable Vesting NFTs
Learn about the standard enabling new NFT and bonding capabilities for users and projects
Since the launch of the ERC-721 standard for non-fungible tokens in 2018, the crypto world has seen NFTs evolve in ways that would have been difficult to imagine five years ago. New use cases and capabilities are fundamentally changing the way users interact with not only the NFTs themselves, but also with the projects and companies behind the NFTs.
Core contributors to ApeSwap, a decentralized exchange and bonding protocol, and team members of Paladin, a blockchain security provider, collaborated to develop an extension to the ERC-721 standard that allows for exciting new functionality for NFTs. The EIP-5725: Transferable Vesting NFT standard is the result of careful consideration of what NFTs can and should be, as well as many rounds of real-world testing and iteration.
What is EIP-5725?
An Ethereum Improvement Proposal, or EIP, is a document used to recommend and describe standards for the Ethereum community. There are multiple types of EIPs, but EIP-5725 is a ERC (Ethereum Requests for Comments) proposal, meaning that it affects application-level standards and specifications.
The EIP that ApeSwap and Paladin have worked together to create is called EIP-5725: Transferable Vesting NFT. This EIP provides an interface for transferable vesting NFTs which release underlying tokens over time.
While time locks and vesting are both important mechanisms for controlling the distribution of ERC-20 tokens and have been around since the age of ICOs, the lack of standardization across the industry can be problematic. Without a standardized approach, it can be difficult for investors to understand how a particular token is being distributed and what the implications of that distribution might be.
How does EIP-5725 work?
EIP-5725 allows for the implementation of a standard API for NFT based contracts to allow two primary functionalities: transferability, and vesting.
Projects that implement EIP-5725 are able to use their NFTs to represent unvested tokens that belong to the holder of the NFT. In other words, this standard allows projects to either integrate with an existing NFT marketplace, or create their own, to be used as a secondary market for vesting tokens.
Also, using EIP-5725, projects can hold and represent the vested and locked properties of any underlying token (ERC-20 or otherwise) that is emitted to the NFT holder. This standard is an extension of the ERC-721 token that provides basic functionality for creating vesting NFTs, claiming the tokens and reading vesting curve properties.

Who created EIP-5725?
ApeGuru and Apetastic, core contributors to ApeSwap, created the EIP-5725 after realizing that no such standard existed when developing vesting contracts for ApeSwap’s business development partners. They enlisted the help of Paladin to review the contracts and ensure the highest level of security and usability for future projects. ApeSwap used the standard in creating the first ApeSwap Bonds, then called BANANA Bills, to raise protocol-owned liquidity through the sale of discounted vesting tokens in exchange for user LP tokens.
Why is EIP-5725 important?
EIP-5725 allows projects to implement several new capabilities to create value for users and projects:
- Transferability of vesting tokens: When using EIP-5725, vesting tokens are emitted to the holder of a transferable NFT, meaning that users can buy or sell the NFTs that represent unvested tokens. This secondary market offers users more flexibility around the underlying asset, as they can liquidate or trade it at any time.
- Custom NFT art capabilities: EIP-5725 also allows projects to create custom NFT art based on a variety of underlying inputs. For example, projects can choose to include a limited edition seal or color scheme on NFTs of particular significance or value, which can then become one of the considerations when valuing the NFT on a secondary market.
- Novel vesting curves: The vesting curves within EIP-5725 NFTs do not have to be linear — they are entirely customizable, and can have accelerating or decelerating vesting depending on the use case required by the project.
- Aggregated, holistic views of vesting tokens and properties: The standard EIP-5725 API enables projects to create holistic dashboards and reporting tools that aggregate the status of their vesting NFTs across entire chains, which can help the project make more informed strategic decisions about future releases and marketing efforts.
How are projects using EIP-5725 right now?
ApeSwap has used the EIP-5725 standard to create a category of products called ApeSwap Bonds (formerly known as Treasury Bills). ApeSwap Bonds allow crypto projects to create transferable NFTs that users purchase with liquidity provider tokens. Holders of the NFTs then receive the project’s native token at a discount, which is set by a variety of factors including Bond supply and token prices, linearly over the course of a vesting period set by the project.
This serves two purposes — first, users get access to discounted tokens that vest over time instead of having to buy them directly at current market prices, and second, projects receive LP tokens that represent liquidity they now own and control. This approach is superior to the traditional yield farming model in that the capital that a project puts forth in the form of discounted tokens generates a return in the form of project-owned liquidity, as opposed to rented liquidity where reward tokens spent generate no return for the project.
To date, ApeSwap has created nearly $1M worth of protocol-owned liquidity for itself and over $1.5M worth of liquidity owned by its partners through the sale of ApeSwap Bonds based on the EIP-5725 standard.
Why should users educate themselves on EIP-5725?
ApeSwap and Paladin are excited to promote the EIP-5725 standard to the crypto community at large to enable users to take advantage of the many opportunities that it creates. Users who are interested should learn more about ApeSwap Bonds in the documentation and stay tuned for new Bonds partners and capabilities launching soon.

What else should users know about EIP-5725?
The EIP-5725 standard is still in “draft” status and is awaiting further validation before moving to “review” status. Users and project contributors are encouraged to add to the ongoing discussion at the Ethereum Magicians forum, and ApeGuru and Apetastic invite anyone with questions about EIP-5725 to reach out to them on Telegram at @Apegurus and @Ape_tastic, respectively.
