Ion Protocol

Ion Protocol is a decentralized money market purpose-built for all types of staked and restaked assets. Ion protocol unlocks capital efficiency for yield-bearing staking collaterals using reactive interest rates, collateral-specific utilization, and price-agnostic liquidations. Borrowers can collateralize their yield-bearing staking assets to borrow WETH, and lenders can gain exposure to the boosted staking yield generated by borrower collateral.

Usage

Installing Dependencies

Install Bun

curl -fsSL https://bun.sh/install | bash

Run Bun install for javascript dependencies

bun install

Install jq

brew install jq

Environmental Variables

Copy .env.example to .env and add environmental variables.

MAINNET_RPC_URL=https://mainnet.infura.io/v3/
MAINNET_ARCHIVE_RPC_URL= # Archive node used for creating fork environments
MAINNET_ETHERSCAN_URL=https://api.etherscan.io/api
ETHERSCAN_API_KEY=
RPC_URL= # RPC of the desired testnet used in deployment scripts

Test

1. The test suite includes fork tests that require foundry ffi.

2. Add RPC_URLs to the .env and run forge test with the --ffi flag.

forge test --ffi

Testnet Setup

1. Set up anvil as a mainnet fork.

   • For the contracts using mainnet contract addresses as constants to work properly, the testnet needs to be a fork of a mainnet environment.

   anvil --fork-url $MAINNET_ARCHIVE_RPC_URL --chain-id 31337

2. Set anvil as the target RPC for the deployment script in .env

   # ...other environmental variables
   RPC_URL=http://localhost:8545
   

3. Run the testnet deployment script

   bash node.sh

4. Run the foundry script to verify that the contracts are working properly.

   forge script script/__TestFlashLeverage.s.sol --rpc-url $RPC_URL

Format

$ forge fmt
