Yield optimizer for Curve Finance LP tokens. Deposit Curve LP tokens to earn boosted CRV rewards plus CVX incentives without needing to lock CRV.

​
What it offers

  • deposit: Deposit Curve LP tokens into Convex pool (with auto-staking)
  • withdraw: Withdraw Curve LP tokens from Convex pool
  • getReward: Claim accumulated CRV + CVX + extra rewards

​
Notes

  • Pool IDs (pid) are sequential integers
  • Third param in deposit = auto-stake in reward pool (always pass true for yield)
  • Each pool has its own BaseRewardPool contract (get from poolInfo.crvRewards)
  • Approve Curve LP token to Booster before depositing
  • getReward with claimExtras=true claims CRV + CVX + any extra reward tokens

​
Its names in a program

On Ethereum, Convex is a namespace: its contracts need no import.

​
ABI

Where a line says what an address it returns is, a program that calls the function through its namespace calls that contract’s methods on the result directly: <Namespace>.<Contract>.<function>(...).<method>(...). A token’s methods are the ERC-20 functions, and its writes are SafeERC20.

​
BaseRewardPoolABI

import BaseRewardPoolABI from "./protocols/convex/BaseRewardPoolABI.json";
  • getReward(address _account, bool _claimExtras) returns (bool)
  • earned(address account) view returns (uint256)
  • balanceOf(address account) view returns (uint256)
  • withdrawAndUnwrap(uint256 amount, bool claim) returns (bool)

​
BoosterABI

import BoosterABI from "./protocols/convex/BoosterABI.json"; Speaks for: booster.
  • deposit(uint256 _pid, uint256 _amount, bool _stake) returns (bool)
  • withdraw(uint256 _pid, uint256 _amount) returns (bool)
  • poolLength() view returns (uint256)
  • poolInfo(uint256) view returns (address lptoken, address token, address gauge, address crvRewards, address stash, bool shutdown): lptoken is a token, token is a token, crvRewards is a Convex.BaseRewardPool
