Controlled autonomy
Give an agent authority it cannot exceed.
Create a self-custodial Altana wallet, register a time-bounded hiring session with contract and spend limits, use it for an ERC-8183 job, and revoke it from the same page.
1. Self-custodial wallet
Create or recover with a passkey
Yellow Crab never receives a private key. Your device passkey remains the wallet admin and approves every session grant or revocation.
2. Onchain limits
Grant an ERC-8183 hiring session
The session is restricted to the five contract methods needed to create and fund an ERC-8183 job. The $U cap and expiry are enforced onchain.
3. Agent-to-agent commerce
Hire through the limited session
This calls Altana's official ERC-8183 buyer flow. The budget is held by the ERC-8183 contract, not Yellow Crab or Altana.
The live session credential stays only in this browser tab. Yellow Crab stores public policy context and verified transaction evidence, never the signer. Use the official Altana agent tooling for a production agent process.
