Cryptonly currently supports these crypto currencies:

Currency	Network

Fiat settlement currencies (used as fiatCurrencyCode on POST /invoice) include USD, EUR, and other common currencies — see GET /currencies/fiat for the exact list available to your account.

Fetching currencies via the API

• GET /currencies — list supported crypto currencies, optionally filtered with ?network= (e.g. Tron). Each entry includes decimalPlaces, minDepositAmount, minWithdrawalAmount, depositCommission (your tenant's effective rate), contractAddress (for tokens), and an optional addressMask regex for client-side address validation.
• GET /currencies/fiat — list supported fiat currencies for invoices, with decimalPlaces and minInvoiceAmount.

Use these endpoints rather than hardcoding currency lists or minimums — available assets and thresholds can change per tenant and over time.
