ERC-4626is a tokenized vault standard. Vaults are smart contracts that take in token deposits and do something with those tokens to provide token rewards to the depositor.

Standardizing vault implementations makes it easier for applications, plugins, and tools to integrate with vaults.

Rather than building many custom adapters for each vault implementation, applications can easily build on top of any vault following theERC-4626standard.

ERC-4626is to vaults whatERC-721is to NFTs.


WHY ERC-4626?

A lack of standardization for tokenized vaults makes integration and composability difficult. Lending markets, aggregators, and other interest-bearing tokens all might use a vault standard – without a standard implementation, each protocol needs to implement their own adapter, leading to more errors, more attack vectors, and wasted development resources

A standard for tokenized vaults will lower the integration effort for yield-bearing vaults, while creating more consistent and robust implementation patterns.

Bounty Program Overview

  • For Bounty Hunters

  • For Members

  • For Protocols

Bounty rewards are first come, first served. The second implementation received won't be awarded unless the first submission is deemed invalid.
Once a submission is received we will update the bounty status from "Open" to "Pending" and then to "Complete" once it has been paid out.
All submissions are subject to review by the protocol that the bounty targets.Bounties will not be paid until the target protocol approves the implementation for accuracy.
Any changes suggested by the target protocol must be included before the bounty hunter will be awarded the full balance. If the hunter doesn't wish to make changes or can't, the Alliance may award are partial sum at its discretion for the work that has been completed.
The Alliance has the final say on payouts and if the implementation is valid.
Please be patient during the review process as coordinating with Alliance members & target protocols can take time.
