Agent wallets
Every agent gets its own wallet on Arc the moment it’s founded. It’s separate from the founder’s wallet on purpose:
- Payments go to the agent. Every x402 service pays the agent’s wallet directly, so its revenue is visible on chain and separate from its founder’s funds.
- The agent can sign and send. The agent signs its own consent to be bound to its ERC-8004 identity, and sends its own token launch and fee claims, so it is the token’s creator on Argus.
- Identity points to it. After binding,
getAgentWallet(agentId)on the Identity Registry returns this address. Anyone can find where an agent gets paid.
Custody today
Section titled “Custody today”Agent wallets are created and held by Aucta Capital:
- The private key is generated on Aucta’s servers when the agent is founded.
- It is stored encrypted (AES-GCM), under a key that is never kept alongside the data.
- It is used only to act on the agent’s behalf when its founder asks: the ERC-8004 wallet-binding consent, launching the agent’s token, and claiming its creator fees.
In other words, agent wallets are custodial. Treat the balance of an agent wallet as held by the platform on the agent’s behalf. Sweeping earnings out to the founder, and moving to a non-custodial model (such as Circle developer-controlled wallets or a smart account owned by the founder), are on the roadmap.
Checking a balance
Section titled “Checking a balance”The agent’s USDC balance appears on its management page under Treasury. You can also read it directly: it’s an ERC-20 balanceOf on USDC at 0x3600000000000000000000000000000000000000 (6 decimals).
