Fraxtal Contracts

Setup

1. npm install
2. Make sure your submodules in /lib are optimism@e6ef3a900c42c8722e72c2e2314027f85d12ced5 and frax-standard-solidity@latest. See https://www.git-scm.com/book/en/v2/Git-Tools-Submodules for additional help
3. Install the Go binary.
4. forge build
5. Set up your .env based on .env.EXAMPLE
6. In your .env, set FOUNDRY_PROFILE to the folder group you want to work with

Test Example

MAKE SURE TO SET YOUR .env to FOUNDRY_PROFILE="fraxtal" or FOUNDRY_PROFILE="vefxs" or FOUNDRY_PROFILE="miscellany" DUE TO SOLC VERSIONING ISSUES, AS MENTIONED ABOVE clear && source .env && forge test --fork-url $MAINNET_RPC_URL --match-path ./src/test/VestedFXS-and-Flox/e2e/E2E_VeFXS.t.sol --match-contract Fuzz_MegaTest_VeFXS -vvvvv

Verification

Regular contracts

Try using forge verify-contract first source .env && forge verify-contract --chain-id 252 --watch --num-of-optimizations 10000 --etherscan-api-key $FRAXTAL_API_KEY --constructor-args $(cast abi-encode "constructor(address)" "0x007FD070a7E1B0fA1364044a373Ac1339bAD89CF" true) 0xC540f05BF5a09336078634D65E46242DFBa55030 src/contracts/VestedFXS-and-Flox/VestedFXS/VestedFXSUtils.sol:VestedFXSUtils source .env && forge verify-contract --chain-id 252 --watch --compiler-version "0.8.26" --evm-version "cancun" --num-of-optimizations 100000 --rpc-url $FRAXTAL_RPC_URL --etherscan-api-key $FRAXTAL_API_KEY --constructor-args 0x000000000000000000000000625e700125ff054f75e5348497cbfab1ee4b7a40 0xBFc4D34Db83553725eC6c768da71D2D9c1456B55 src/script/Miscellany/Proxy.sol:Proxy CHECK THE PROXY OUT FOLDER TO SEE THE OPTS/RUNS/EVM/COMP STUFF BECAUSE SOMETIMES IT IS OLDER AND IS DIFFERENT FROM THE IMPLEMENTATION!!!

If this fails, try forge flatten

1. forge flatten --output src/flattened.sol src/contracts/VestedFXS-and-Flox/VestedFXS/VeFXSYieldDistributor.sol
2. sed -i '/SPDX-License-Identifier/d' ./src/flattened.sol && sed -i '/pragma solidity/d' ./src/flattened.sol && sed -i '1s/^/\/\/ SPDX-License-Identifier: GPL-2.0-or-later\npragma solidity >=0.8.0;\n\n/' ./src/flattened.sol
3. Take the contents of your new flattened.sol file and do the Etherscan verification manually

Verifying a proxy

1. https://fraxscan.com/proxycontractchecker?a=PROXY_ADDRESS_HERE
2. TRY source .env && forge verify-contract --chain-id 252 --watch --num-of-optimizations 100000 --evm-version "cancun" --etherscan-api-key $FRAXTAL_API_KEY --constructor-args $(cast abi-encode "constructor(address)" "0x625e700125FF054f75e5348497cBFab1ee4b7A40" true) 0x437E9F65cA234eCfed12149109587139d435AD35 src/script/VestedFXS-and-Flox/Proxy.sol:Proxy
3. OR (2) but with --show-standard-json-input and paste that into the verifier
4. If you are still having problems, make sure the constructor args are padded properly, etc. Sometimes Etherscan guesses the wrong ones.

Code Coverage

1. forge coverage --ir-minimum --report lcov && genhtml lcov.info -o report --branch-coverage --ignore-errors category.
2. Go to /report and browse the html
3. OPTIONAL: forge coverage --report summary (shows a coverage report in the terminal)
4. OPTIONAL: VS Code: install Coverage Gutters or a similar extension to see the coverage inside VSCode tabs

Tooling

This repo uses the following tools:

• frax-standard-solidity for testing and scripting helpers
• forge fmt & prettier for code formatting
• lint-staged & husky for pre-commit formatting checks
• solhint for code quality and style hints
• foundry for compiling, testing, and deploying
