Metapool product for staking on Ethereum, receiving in exchange mpETH.

Allows users to stake ETH or WETH, instant redeem of mpETH (with a small fee) or delayed redeem (1 to 7 days) and add liquidity with ETH or WETH (for instant redeem).

NOTE: Goerli is no longer supported, use Sepolia testnet.

Main contract responsible of managing the staking of ETH/WETH and redeem of mpETH

Liquidity pool to allow users to immediately exchange mpETH for ETH, without any delay but with a small fee. Also users can provide liquidity with ETH or WETH. This ETH will be slowly converted to mpETH through swaps and the Staking contract can also use this ETH (with some limitations) to create new validators, minting new mpETH for liquidity providers.

Manage the delayed mpETH redeem of users. Send ETH from rewards and validators disassemble to users. Users request the withdraw in the Staking contract and, one epoch later (one week) complete the withdraw on this contract.

This project use multiple .env files

• .env for common variables to all network
• .env.<network> for network specific variables

For testing with hardhat generated accounts, the .env only requires:

NETWORK="Network used for all commands"

If NETWORK is not set, hardhat will try to use the Sepolia network.

For production you will need extra variables. Check .env.sample for a list of all variables 

Above this, each network requires a .env.<network> file with the following variables:

RPC_ENDPOINT="RPC endpoint URL"
BLOCK_NUMBER="Block number to fork"

Note:

• All commands also compile the contracts

npm run compile

npm test

npm run deploy <network>

npm run verify <network>

TARGET=Staking npm run upgrade <network>

npm run transfer_to_multisig <network>

This only transfer the admin permission to upgrade the contracts implementations, not the ADMIN_ROLE
