Fundu never stores or has access to your private keys. All transactions require your explicit approval through your wallet. We use Sign-In with Ethereum (SIWE) for authentication — your wallet proves your identity without exposing secrets.
Our smart contracts manage circle contributions and payouts on the Base blockchain. Contract logic enforces payment schedules, payout order, and fund distribution automatically — removing the need to trust any single party.
Every contribution and payout is recorded on the blockchain and can be independently verified. Circle balances, payment statuses, and payout history are all visible on-chain. No hidden ledgers, no opaque accounting.
