Supported cryptocurrencies

Caution

The source of truth is the GET /currencies endpoint. The supported list can change at any time (new networks added, currencies removed due to regulatory compliance).

Before deploying your integration, call the endpoint and validate the symbol you want to use.

Current snapshot

How symbols work

In B4bit Pay each (currency, network) combination has its own symbol. For example, USDC exists on multiple networks:

• USDC → Ethereum
• USDC_POLYGON_NXTB → Polygon
• USDC_ARB_3SBJ → Arbitrum
• USDC_OPT_9T08 → Optimism
• USDC_BASECHAIN_ETH_5I5C → Base
• SOL_USDC_PTHX → Solana
• TRX_USDC_6NU3 → Tron
• USDC_AVAX → Avalanche

When you create an order with POST /orders/, pass the exact symbol you want to charge. Obtain it from GET /currencies.

Mandatory TAG/MEMO

Danger

The XRP, XLM and ALGO currencies require a TAG or MEMO in addition to the address. If the customer does not enter the TAG/MEMO along with the address and amount when paying, the funds are unrecoverably lost.

If you integrate via the API Gateway, make sure to prominently display the tag_memo to the user.

Bitcoin Lightning

BTCL uses the Lightning Network, an instant off-chain payment protocol. The flow is different: instead of an address + amount, B4bit Pay returns a BOLT11 invoice that the customer pays with their Lightning wallet.
