# 8.7. Security

The replica marketplace relies on Ethereum's security for smart contract functionality. The only wallet that can affect the logic of our smart contracts is a multi-signed wallet that uses a Gnosis MultiSig wallet with three hardware wallets.

The backend side manages databases that cache smart contract events to track ownership. The backend also stores temporary assets.

As a result, the responsibility is minimal, and for the fight payment hot wallet, the automatic daily refill is designed so that there will be minimal tokens to prevent or minimize defensive defects.
