Dev

Pre Requisites

Submodule

$ git submodule init
$ git submodule update

Install

$ yarn install

Compile

Compile the smart contracts with Hardhat:

$ yarn compile

TypeChain

Compile the smart contracts and generate TypeChain artifacts:

$ yarn typechain

Lint Solidity

Lint the Solidity code:

$ yarn lint:sol

Lint TypeScript

Lint the TypeScript code:

$ yarn lint:ts

Test

Run the Mocha tests:

$ yarn test

Run fork tests

$ yarn test:fork:all

Tasks

Running in fork mode

$ NODE_URL=<FORK_URL> yarn task:fork <TASK_NAME>

Running task normally

$ NODE_URL=<NODE_URL> yarn task --network <NETWORK> <TASK_NAME>

Coverage

Generate the code coverage report:

$ yarn coverage

Clean

Delete the smart contract artifacts, the coverage reports and the Hardhat cache:

$ yarn clean

Local Fork

This runs a local node on your system, that can be used with Metamask, etc.

Run a local fork:

npx hardhat node --fork https://eth-mainnet.alchemyapi.io/v2/<API_KEY> --port <PORT>

Once you stake or lock CVX you may want to progress timestamps to check rewards stuff

export NODE_URL=<LOCAL_NODE_URL>
yarn task timeTravel --duration 69420 --network forking

Notes

Warnings

• auraBAL and vlAURA reward contracts are not on the 4626 standard

• StashToken contracts are not ERC20 compliant. convex-platform/contracts/contracts/StashToken.sol it is designed to interact only with VirtualBalanceRewardPool and ExtraRewardStashV3. Any extraRewards is distributed by a VirtualBalanceRewardPool, which is linked to a StashToken, the StashToken wraps the extraReward as a baseToken.
