Security Measures

Security is core to AfriLance. Escrow contracts include non-reentrancy guards to prevent attack vectors, role-based access controls (e.g., only client can approve, freelancer submit), and time-locks for fund withdrawals to avoid rush disputes. Funds are held in the contract until release, with no admin access; pure decentralization. On-chain verification ensures transparency, and AI pre-screens disputes to reduce malicious claims. The platform undergoes regular audits, and BNB Chain's robust network adds layer-1 security. Users are protected from scams through verified profiles and escrow-only payments.
