Swapper contracts are used to swap tokens on-chain. Swaps can be done synchronously via aggregators like 1Inch or Automated Market Makers (AMMs) like Uniswap. They can also be done asynchronously with aggregators like Cowswap.
Vaults that can swap underlying assets as part of a rebalancing process. Vaults can also swap reward tokens for vault assets.
