Mellow Vaults

We're buliding permissionless vaults ecosystem for trustless automatic DeFi strategies. The protocol is designed for implementing multi-token cross-protocol liquidity rebalancing.

The Vault contracts hold the tokens and rebalance them both inside other protocols and between them. Strategy contracts interact with Vault contracts definig the rebalancing parameters.

Liquidity provider Users pick a strategy that fits their needs and allocate their assets into a vault to earn yield. When the assets are deposited, users get composable LP tokens (ERC-20).

Strategies Strategies are smart-contracts that implement the models to provide effective liquidity allocation. Different market events can trigger the strategies to initiate rebalance.

Vaults Vaults allocate multiple ERC-20 tokens into other DeFi protocols and rebalance the liquidity in accordance with Strategies inside and between the protocols.
