# ConsensusLayerDepositManagerV1

*Alluvial Finance Inc.*

> Consensus Layer Deposit Manager (v1)

This contract handles the interactions with the official deposit contract, funding all validatorsWhenever a deposit to the consensus layer is requested, this contract computed the amount of keys that could be deposited depending on the amount available in the contract. It then tries to retrieve validator keys by calling its internal virtual method \_getNextValidators. This method should be overridden by the implementing contract to provide \[0; \_keyCount] keys when invoked.
