A deep dive into the ERC-4626 Ecosystem 🧩
We explore some of the vast ecosystem of #DeFi projects building on the #ERC4626 standard.
We explore some of the vast ecosystem of #DeFi projects building on the #ERC4626 standard.
1/ Standards in traditional technology are one of the most powerful catalysts. They drive interoperability, ecosystem development, and future innovation.
2/ Crypto is no exception to this: ERC-20, ERC-721, ERC-4626. Standards are the condition for a successful composable and permissionless ecosystem.
3/ ERC-4626 is one of the most exciting standards for Ethereum. As a standard for tokenized vaults, it lowers the integration effort for yield-bearing vaults that are powering many DeFi projects.
4/ Beyond substantially decreasing integration costs, this standard natively creates a derivative asset, generating a new kind of liquidity independent from the underlying assets.
5/ Here are some interesting protocols building on ERC-4626 that caught our attention.
6/ @Timeless_Fi
Timeless is a yield market protocol that lets you boost, hedge, and trade yield.

7/ Instead of just parking your money into a classic yield farm, Timeless enables users to boost their yield, hedge against falling yield rates or speculate on yield rate changes.
8/ Timeless supports yearn and ERC-4626 vaults and anyone can use their Factory to deploy new yield tokens and liquidity pools, while it previously released an open source repository of ERC-4626 wrappers for popular projects called Yield Daddy github.com/timeless-fi/yi….
9/ @iearnfinance
Yearn is a yield aggregator where users, protocols, and DAOs can deposit digital assets into various capital pools known as vaults and receive yield.

10/ The vaults help to socialise gas costs, automate yield generation and rebalancing processes, and shift capital when opportunities arise.
Yearn V3 uses ERC-4626 for their vaults, which means these deposits can be funnelled to other ERC-4626 vaults easily.

15/ Balancer uses ERC-4626 on their Linear pools, the base component of Boosted Pools to facilitate trades between two tokens at a known exchange rate with linear math.
16/ With ERC-4626, you can create a linear pool from any ERC-4626-compatible wrapped token, which then can be subsequently used to create a Phantom Stable pool and Boosted Pool in combination with any lending platform like Aave.

aztec.network
25/ This bridge allows people to issue and redeem shares of any ERC4626 vault after the vault is listed in the contract, and also enables any protocol conforming to the ERC-4626 standard to be easily added to Aztec Connect.

27/ With its unique ability to provide collateral that can also generate yield, Alchemix can offer a self-paying loan that has effectively no risk of liquidation.
28/ Alchemix is working on an ERC-4626 adapter for their contract so that they can use ERC-4626 vaults as new yield sources.
29/ @element_fi

32/ It separates the principal and interest components of a position by issuing two FNFTs; one containing the principal and the other containing the rights to future interest on that principal.
33/ Resonate facilitates the commerce of the rights to future interest by matching issuers and purchasers.
Resonate will be supporting lending pools with ERC-4626 adapters and offering lenders new ways to receive fixed-rate returns. Resonate will launch in Q3 2022.

docs.frax.finance/frax-ether/tec…
39/ sfrxETH is an ERC-4626 compliant vault. sfrxETH is obtained by first approving the sfrxETH contract as a frxETH spender, and then calling mint() (mints a specific number of sfrxETH) or deposit() (deposits a specific amount of frxETH).
40/ @mstable_
mStable is a secure and composable layer for yield with vaults built on ERC-4626. It aims to power the next generation of composable vault infrastructure with its Meta Vaults starting with a Convex-centric vault in mid-Q4.

41/ mStable’s ERC-4626 Save and Convex strategies have pioneered gas-efficient, optimised yield strategies for depositors to earn and compound yield in a decentralised, secure manner.
42/ The world of ERC-4626 has just emerged since the standard was introduced earlier this year.
“Dual-layer assets”, separating the vault underlying assets from the tokenized version, brings augmented capabilities to the worn-out “LEGO” in the DeFi-world.

43/ What if you could:
Design and integrate compliant ERC-4626 vaults with insurance coverage effectively being paid from the yield in real-time, create native money markets for any vault token unlocking leverage...

44/ ...or even bridge and perform complex and frequent cross-chain rebalancing between multiple vaults?
From ERC-4626 bridges to fixed-rate lending, yield aggregation, liquidity pools… the list goes on.

45/ mStable and many others are extremely excited about the unlimited possibilities in this space.
Reflecting on the power of standards, mStable realized that broad adoption is a prerequisite for it to become a game changer in DeFi.

46/ With early adopters of the standard, mStable is building the 4626-Alliance, a fertile ground for 4626-builders to foster collaboration and push the standard.
