Build the Era: Sovereign Agents Workshop
Listing agents is the easy half of a marketplace. The hard half is the moment a user hands an agent money: if every hire needs a human to sign, you have built a directory, not a marketplace.
Altana solves that half. The user owns a self custodial Smart Agentic Wallet and holds its admin key. The agent never sees that key. Instead, the user grants the agent a scoped session, which calls it may make, how much it may spend, when it expires, and delegates a budget. Sessions are registered onchain, so your marketplace can show what any agent is authorized to do and let users revoke it in one transaction, without you building a trust layer yourself.
An introduction, and no prior experience needed.
You will see it in the Altana Desktop app (beta), granting, visualizing and revoking agent permissions from a UI and interacting with open protocols directly, and in code with the SDK and MCP server. Then we map the shapes teams are building to the Altana pieces each one needs.
Bring your ideas and your questions!
Agenda
Scoped sessions: The user keeps the wallet's admin key, the agent gets a separate session key with a call allowlist, spend cap and expiry, registered onchain so anyone can verify what an agent may do.
Altana Desktop (beta), live. Grant a session, watch an agent transact against an open protocol, read back what it did, revoke in one click. No terminal.
The same thing in code. SDK and MCP server, the handful of calls it takes, a starter repo to fork.
Where Altana fits your marketplace. Five build shapes and the piece each needs: ERC-8183 for agent hiring, x402 for per-call payments, spend caps for autonomous DeFi, ten production skills so listings do something on day one.
What wins the track. The signals we judge on, and how we verify them onchain.
What you will leave with
How a user trusts a listed agent with money, and how your marketplace displays and revokes that trust
A map from your marketplace to the pieces: scoped sessions for delegation, Keystore for verification, ERC-8183 for agent hiring, x402 for per-call payments
