In the evolving landscape of AI agents, the challenge of control emerges. While smart contracts offer financial autonomy, their reliance on blockchain restricts AI’s potential by limiting data processing and interaction with off-chain systems. As AI agents require advanced computing power, their autonomy falters outside the blockchain. The concept of a sovereign proxy, which ensures agents remain secure and independently verifiable, becomes critical. This article outlines a seven-pillar technology stack to maintain agent sovereignty while allowing complex interactions. Key components include identity management via ERC-8004, seamless payment protocols like x402, and verifiable computation through trusted execution environments. Solutions for determinable AI outputs and immutable record-keeping enhance agent accountability. Additionally, advanced wallets enable controlled autonomy, and coordination frameworks cultivate a marketplace for specialized skills. Ultimately, sovereign proxies empower AI agents, ensuring they operate under their owner’s control and achieve true autonomy in various environments while maintaining security and trust.
