# Kraken

**What it is.** A large, long-established multi-asset exchange with broad fiat pairs and a mature trading API. Not Bitcoin-only.

**What it bridges.** Fiat ↔ BTC and **BTC ↔ stablecoin**, across many fiat currencies — useful where an agent's counterparties or jurisdictions are outside US-centric rails.

**Agent access.** Full programmatic **API** (spot trading, funding, withdrawals).

**How an agent uses it.** KYC account; fund; execute fiat↔BTC or BTC↔stablecoin via API; withdraw to self-custody promptly. Custodial risk during the holding/conversion window.

**Coverage.** Broad international coverage across many fiat currencies; exact per-region availability shifts — see the venue.

**Dependencies & payment.** A KYC'd Kraken account and its trading API. Fund in one of many fiat currencies; execute fiat↔BTC or BTC↔stablecoin via API; withdraw to self-custody promptly.

**Gotchas.** Multi-asset custody surface (freeze surface spans the account and all held assets).

**Links.** [kraken.com](https://kraken.com) · [API docs](https://docs.kraken.com).
