Foundry

Foundry is a blazing fast, portable and modular toolkit for Ethereum application development written in Rust.

Foundry consists of:

• Forge: Ethereum testing framework (like Truffle, Hardhat and DappTools).
• Cast: Swiss army knife for interacting with EVM smart contracts, sending transactions and getting chain data.
• Anvil: Local Ethereum node, akin to Ganache, Hardhat Network.
• Chisel: Fast, utilitarian, and verbose solidity REPL.

source .env
forge script script/Deploy.sol:SepoliaScript --slow --broadcast --verify --rpc-url ${SEPOLIA_RPC_URL}

if verification fails:

forge verify-contract --watch --chain sepolia --constructor-args $(cast abi-encode "constructor(string,string,address,address,address)" "Harberger Tax" "HARB" "0x0227628f3F023bb0B980b67D528571c95c6DaC1c" "0xb16F35c0Ae2912430DAc15764477E179D9B9EbEa" "0x64dda11815b883c589afed914666ef2d63c8c338") 0x7517db0f2b24223f2f0e3567149ca180e204da8a Harb

forge verify-contract --watch --chain sepolia --constructor-args $(cast abi-encode "constructor(address)" "0x7517db0f2b24223f2f0e3567149ca180e204da8a") 0x00b4d656b8182d0c2f4841b7a6f1429b94f73a66 Stake

open features:

• reduce snatch collision
• profit for staking position
• tax paid for staking position
• deployment on L2

todos:

• liquidation bot
• write unit test for capital exit function
• put ownerOnly restriction on recenter, remove it later. gives more control to the team initally, but keeps it decentralized
