Bastion is a lending and exchange protocol built on Aurora, the Ethereum-compatible layer of the Near blockchain. Bastion builds an autonomous interest-rate engine with high-quality capital efficiency, quick transactions, low transaction fees, accurate liquidations, and leverages NEAR's underlying UX benefits. Users can deposit assets into the Bastion liquidity pool, and the protocol will generate collateral tokens. These cTokens earn interest based on the underlying asset value and can be used as loan collateral in the future.
