Aave

Yearn Finance is a suite of products in Decentralized Finance (DeFi) that provides lending aggregation, yield generation, and insurance on the Ethereum blockchain. The protocol is maintained by various independent developers and is governed by YFI holders. The first Yearn product was a lending aggregator. Funds are shifted between dYdX, AAVE, and Compound automatically as interest rates change between these protocols. Users can deposit to these lending aggregator smart contracts via the Earn page. This product completely optimizes the interest accrual process for end-users to ensure they are obtaining the highest interest rates at all times among the platforms specified above. Capital pools that automatically generate yield based on opportunities present in the market. Vaults benefit users by socializing gas costs, automating the yield generation and rebalancing process, and automatically shifting capital as opportunities arise.

Bancor is a protocol for the creation of Smart Tokens, a new standard for cryptocurrencies convertible directly through their smart contracts. Bancor is an on-chain liquidity protocol that enables automated, decentralized exchange on Ethereum & across blockchains. The Bancor Protocol is a fully on-chain liquidity protocol that can be implemented on any smart contract-enabled blockchain. The Bancor Protocol is an open-source standard for liquidity pools, which in turn provide an endpoint for automated market-making (buying / selling tokens) against a smart contract. Bancor Network currently operates on the Ethereum and EOS blockchains, but the protocol is designed to be interoperable for additional blockchains. Our implementation can be easily integrated into any application enabling value exchanges. Our implementation is open source and permissionless, and ecosystem participants are encouraged to contribute to and enhance the Bancor Protocol.
