# Create a crypto address

> Provisions a deposit address for one asset on one chain (e.g. USDC on Solana). Deposits are credited to your balance in that asset once confirmed and fire a `collection.completed` webhook. Addresses are one per `currency` + `chain` per organization: re-requesting the same pair returns the existing address (still 201). Supported pairs are listed under `deposits` in the capabilities catalog.
