Application layer

One agent balance, multiple currencies

Wallet OS is the operator layer behind a Pulsar-style experience: agents keep a USDC spending base, price invoices in EURC, and prepare fiat funding paths without exposing the custody complexity underneath.

Circle Wallet execution

Connect key

Wallet OS checks the Circle path before a policy-gated transfer is attempted: credentials, source wallet, Arc Testnet USDC token lookup, readable balance, recipient policy and smoke-transfer guardrails.
