Isolated Agent Architecture

Yield Seeker is designed with a strong focus on security, isolation, and user control. Each AI agent operates in its own secure smart wallet. These wallets are fully isolated from one another, meaning no agent can access or interfere with another agent’s funds. This structure ensures strict separation of user assets and prevents any cross-agent vulnerabilities. Only the wallet owner has permission to withdraw funds. Yield Seeker cannot independently move or withdraw user funds.

Trusted Key Management

Private keys are secured using Coinbase’s Trusted Execution Environment (TEE). This infrastructure protects sensitive key material through encryption and hardware-based isolation. The TEE ensures that private keys remain inaccessible—even during transaction execution—and cannot be exposed to external systems or internal services. This approach is widely used in institutional-grade custody systems and significantly reduces the risk of key compromise.

Smart Wallet Delegation via EIP-7702

Yield Seeker wallets implement EIP-7702, enabling secure transaction delegation without exposing private keys. This allows your agent to execute transactions autonomously while minimizing attack surface and maintaining robust key security. Delegated permissions are scoped and controlled, allowing agents to perform specific operations without granting unrestricted access to funds.

Smart Contract Security

Yield Seeker’s smart contracts have been independently audited by Nethermind, a leading blockchain security firm. The audit reviewed core contract logic, agent execution flows, and fund management mechanisms to identify potential vulnerabilities, edge cases, and attack vectors. All critical and high-severity findings were addressed prior to deployment. You can review the full audit report here:

Full User Control

Users maintain full control of their funds at all times. Only the user can initiate withdrawals through the Yield Seeker interface via the Wallet page. In the unlikely event that the platform becomes inaccessible, funds can still be recovered without relying on the Yield Seeker interface. While we do not have access to user funds, we can assist in guiding users through the recovery process if needed.

Defense in Depth

Yield Seeker combines multiple layers of protection to reduce risk across the system:
  • Isolated agent wallets prevent cross-user access
  • Private keys secured using Coinbase’s Trusted Execution Environment (TEE)
  • EIP-7702 delegation restricts agent permissions
  • Independently audited smart contracts
  • Full user withdrawal control at all times
No system is completely risk-free, but this layered architecture is designed to minimize attack surface and protect user funds under a wide range of conditions.

Built for Safety and Autonomy

Yield Seeker combines advanced infrastructure, smart contract design, and modern account abstraction standards to deliver a secure, automated experience. From wallet isolation to delegated execution and gas fee coverage, your funds remain protected, efficient, and under your full control.
