Capsule

Capsule is in development; install block appears with the first release.

Capsule is the buyer's own client: it searches the catalogue, asks for a quote and pays within a budget you set, only from your own wallet on your machine. Soukbase never holds the money.

Owner key and agent key

Planned design, not released:

OWNER (you)  --- owner key (in your OS keychain) --->  signs a policy: limits per purchase, day and week
                                                          |
AGENT (the model)  --- agent key (small balance, expiry) --->  searches, asks for a quote, pays inside the limits
                       cannot read the owner key, cannot change the policy, cannot add payees;
                       over the limit it waits for the owner
                                                          |
SELLER WALLET  <--- USDC on Base or Tempo, paid from your own wallet on your machine

Risks of paying in USDC

USDC is issued by Circle. The issuer can freeze USDC at an address. Soukbase cannot prevent or undo a freeze.
Payments are on-chain and final. There is no chargeback and no escrow.
USDC aims to hold 1 USD but is not a bank deposit and is not insured. Its price can differ from 1 USD.
A buyer who pays with stolen or frozen USDC can put the seller's wallet at risk. The Seller Agreement says so (/legal/seller-agreement.md).
A payment sent on the wrong network or to the wrong address cannot be recovered by Soukbase.
