# List crypto currencies

`GET /crypto/currencies`

List all supported cryptocurrencies with live rates.

## Response `200`

Successful response.

- CryptoCurrency[]
  - `chainId` integer, nullable — EVM chain ID a WalletConnect/wagmi client should switch to before signing. Null for non-EVM chains (Solana, Tron, Bitcoin, TON, …) — those need their own connector libraries.
  - `contractAddress` string, nullable — Token contract address for ERC20-style tokens on EVM chains (and SPL mint for Solana). Null for native coins (ETH, SOL, MATIC, BTC, …) where a wallet sends a plain transfer instead of calling a contract.
  - `decimals` integer, required — Decimals for unit conversion. ERC20 tokens vary (USDT=6, DAI=18); native coins follow chain convention (ETH=18, SOL=9, BTC=8). Defaults to 18 when unknown so EVM transfers stay safe.
  - `icon` string, required — SVG icon URL.
  - `id` string, required — 0xProcessing currency identifier, e.g. "USDT (TRC20)" or "BTC".
  - `name` string, required — Human-readable name from manifest, e.g. "Tether".
  - `network` string, required — Network code from the manifest, e.g. "TRC20", "ERC20", "POLYGON", "SOL".
  - `rateUSD` number, required — Price of 1 unit in USD (from Binance; 1.0 for stablecoins).
  - `symbol` string, required — Base symbol, e.g. "USDT".
  - `transferKind` 'EVM_NATIVE' | 'EVM_ERC20' | 'NON_EVM', required — How a frontend should construct the payment transaction.
