Rari Vault Strategies

Simple (potentially composable) Strategies for earning yield on Rari Vaults.

Credits

• t11s, Jet Jadeja, and the whole Rari Capital team for their work on vaults.
• Rain's crop Compound Levered USDC Strategy.
• Georgios Konstantopoulos for the amazing dapptools-template resource.

Strategies

• IdleStrategy.sol: An Idle Strategy which generates no yield for a user's deposit.
• UniswapLP.sol: Provides liquidity into a pool with the underlying and highest fees/liquidity ratio.
  • Uniswap Deploys
• CompoundLender.sol: Lends the underlying to compound.
  • Compound V2 Deploys

• interfaces/: Interfaces of external contracts Vaults and modules interact with.
  • Strategy.sol: Minimal interfaces for ERC20 and ETH compatible strategies.
