## 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. ## Documentation https://book.getfoundry.sh/ ## Usage ### Install ```shell $ git clone $ git submodule init $ git submodule update $ cd lib/uni-v3-lib $ yarn ``` ### Build ```shell $ forge build ``` ### Test ```shell $ forge test ``` ### Format ```shell $ forge fmt ``` ### Gas Snapshots ```shell $ forge snapshot ``` ### Anvil ```shell $ anvil ``` ### Deploy ```shell forge clean forge cache clean source .env forge script script/Deploy.sol:BaseXDeploy --slow --broadcast --verify --rpc-url ${X_RPC_URL} ``` if verification fails: ```shell 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 ``` ### Cast ```shell $ cast ``` ### Help ```shell $ forge --help $ anvil --help $ cast --help ``` ## Deployment on Sepolia ### Harb address: 0x087F256D11fe533b0c7d372e44Ee0F9e47C89dF9 [abi](../subgraph/harb/abis/Harb.json) ### Stake address: 0xCd21a41a137BCAf8743E47D048F57D92398f7Da9 [abi](../subgraph/harb/abis/Stake.json) ### LP address: 0xCc7467616bBDB574D04C7e9d2B0982c59F33D43c [abi](../subgraph/harb/abis/BaseLineLP.json) ## Deployment on Base Sepolia ### Multisig address: 0xf6a3eef9088A255c32b6aD2025f83E57291D9011 ### Harberg address: 0x54838DC097E7fC4736B801bF1c1FCf1597348265 ### Stake address: 0xd7728173F73C748944d29EA77b56f09b8FEc8F33 ### LP address: 0x00E4da809989f40F5D1B31bE6202A5e512db4212 ## References open features: - reduce snatch collision todos: - write unit test for capital exit function - would anchorLiquidityShare affect capitalInefficiency? - could the UBI pool run dry? - what happens if discovery runs out? ## Simulation data: ```json { "VWAP":0, "comEthBal":1234, "comHarbBal":0, "comStakeShare":0, "liquidity":[{ "liquidity":1234, "tickLower":-123, "tickUpper":124 }], "startTime":1234, "txns":[{ "action":5,"timeOffset":0,"x":0,"y":""}, {"action":0,"ethAmount":1,"x":0,"y":""}, {"action":5,"timeOffset":0,"x":0,"y":""}, {"action":0,"ethAmount":2,"x":0,"y":""}, {"action":5,"timeOffset":0,"x":0,"y":""}, {"action":0,"ethAmount":4,"x":0,"y":""}, {"action":2,"harbAmount":3000,"tax":10,"y":""}, {"action":5,"timeOffset":0,"x":0,"y":""}, {"action":4,"positionId":654321,"x":0,"y":""}, {"action":2,"harbAmount":5000,"tax":20,"y":""}, {"action":0,"ethAmount":8,"x":0,"y":""}, {"action":5,"timeOffset":0,"x":0,"y":""}, {"action":1,"harbAmount":20000,"x":0,"y":""}, {"action":5,"timeOffset":0,"x":0,"y":""}, {"action":4,"positionId":654321,"x":0,"y":""}, {"action":2,"harbAmount":8000,"tax":29,"y":""} ] } ```
