The proposal states that the core objective of V3 growth is to offer a significant improve to V2. The ultimate state of V3 ought to be a completely decentralized protocol that gives a safer and dependable infrastructure for on-chain capital allocation.
To realize this objective, the Yearn contributors define 4 important necessities that V3 wants to satisfy:
- Additional decentralization at launch and progressive decentralization over time.
- Simplify coverage writing.
- Higher than Yearn’s V1 technique product.
- Higher than Yearn’s V2 repository.
The primary contract model of Yearn V3 “3.0. publicize different chains.
Concerning the fundamental construction of V3, price range and technique are solely unbiased, Vault is suitable with ERC 4626 in V3. The connection between V3 vaults and their technique has utterly modified and is now utterly separate.

Which means that vaults can’t solely deploy funds to a number of methods, however methods may settle for funds from varied vaults (in addition to non-vault sources comparable to direct deposits from customers).
V3 Vaults are debt managers that approve methods to steadiness debt, and customers can pay for debt administration. In these respects, V3 vaults operate precisely like V2 vaults however with extra enhancements and adaptability.
By complying with 4626, the technique interface is immediately standardized with a number of protocols in DeFi. This permits any 4626-compliant protocol to hook up with the V3 library now, requiring no new implementation or coverage code. This dramatically reduces the complexity of price range accounting and in addition reduces fuel prices.
Concerning the V3 charge construction, for the reason that methods themselves at the moment are treasury-independent, charges in V3 shall be charged on the meta-vault degree in addition to by way of the tokenized methods. V3 additionally introduces a “protocol charge”. Protocol charges are set by Yearn administration and are calculated as a share of the full charges charged upon any V3 price range or technique report.
