Give Your AI Agents a Wallet on Stellar

Smart vaults with delegated spending controls. Agents pay for services autonomously using the x402 protocol while you stay in control of your funds.

Three Primitives, One Protocol

Smart Vaults

Per-user Soroban C-accounts holding USDC with per-agent spending policies. Daily limits, destination whitelists, instant revocation.

Agent Identity (ERC-8004)

On-chain AI agent registry inspired by ERC-8004. Each agent is an NFT with capabilities, pricing, and verifiable identity.

x402 Payments

HTTP 402-based micropayments. Agents pay for services with a single header — no wallets, no popups, no friction.
