Lyra V2 Account Abstraction


lyra

Account Abstraction is here!

This repo contains all contracts that help Lyra v2 achieve Account Abstraction experience. More specifically, for L1 to L2 gasless deposits, we use Gelato relayer; for all L2 transactions, we adopt ERC4337, with our own Paymaster and LightAccount from Alchemy.

Usage

Build

$ forge build

Test

We have a few fork tests for deposit and withdraw helpers. You can run them on Mainnet / Lyra chain with commands below:

# tests on Lyra chain
$ forge test --match-contract FORK_LYRA_ --fork-url https://rpc.lyra.finance

# tests on Mainnet 
$ forge test --match-contract FORK_MAINNET_ --fork-url <mainnet rpc>

Using the contracts

Go see this repo for examples

Deployments

Gasless Deposit Forwarders

Gasless forwarders are used to make sure users only with ERC20 can deposit to Lyra

ETH

Network USDC Selfpaying Forwarder USDC Sponsored Forwarder
Ethereum Mainnet 0x00efac83a3168568e258ab1ec85e85c10cbaf74e 0xf0372da389db728a3173a7b91c5cb4437a6319ea
  • On Ethereum Mainnet, only USDC supports gasless deposit.
  • We use a differnet forwarder here that only work with USDC (receiveWithAuth) to minimize gas cost.

Arbitrum

Network SelfPaying Permit Forwarder Sponsored Permit Forwarder
Arbitrum 0x00eFAc83a3168568e258ab1Ec85E85C10cBAf74E 0xC3621651c550F3c1BC146ffAe0975a566423Da17
Arbitrum Sepolia - 0xE3436F0F982fbbAf88f28DACE9b36a85c97aECdE
  • On Arbitrum, all ERC20s can be gasless (with permit)

Optimism

Network SelfPaying Permit Forwarder Sponsored Permit Forwarder
Optimism 0xAa7Dd6fa6B604b776BCE03Af6ED717c00E66538E 0x062B67001A6dd9FC6Aa1CFB9c246AcfFC4BfAdC5
Optimism Sepolia - 0x1480Cfe30213b134f757757d328949AAe406eA33
  • On Optimism, only USDC has permit now, but other ERC20s can potentially use these contracts to achieve gasless deposit if they have permit.
