Stablecoins depend on issuers, bank accounts, and regulatory decisions an agent can't verify. Bitcoin's 21 million supply cap is enforced by code. An agent can independently verify every block header, every transaction, every signature. For autonomous software, verifiable beats convenient.

When an agent hits an API that returns 402 Payment Required, Claw Cash will read the payment requirements (amount, token, chain, address), swap BTC to the requested stablecoin on the fly, sign the x402 payment authorization, and retry the original request. The agent holds sats as its treasury and pays in whatever currency the API demands. This feature requires ECDSA signing in the enclave — tracked in #5.

Inside an Evervault Enclave. Keys are generated and sealed inside the enclave boundary and never leave it. The CLI communicates with the enclave over an attested TLS channel. Even if the host machine is compromised, the keys remain inaccessible.

Bitcoin on-chain, Lightning, and Arkade (instant off-chain). For stablecoins: USDC and USDT on Polygon, Arbitrum, and Ethereum. The agent holds BTC and swaps to stablecoins on demand via LendaSwap and Boltz.

Yes. Claw Cash acts as a factory bot — your Telegram bot authenticates with a shared API key and gets per-user sessions via POST /v1/auth/bot-session. Each Telegram user gets their own enclave-backed identity. No user-facing auth flow needed.

Instant. Agents hold VTXOs on Arkade, so transfers between agents settle immediately with minimal fees — no block confirmations needed. Lightning payments are also near-instant for paying external services.
