Overview

This document helps you understand which tokens, chains, and currencies are supported for different payment scenarios:
  • Payment collection: Accept stablecoin payments from your customers
  • Pricing: Set prices in familiar fiat currencies
  • Off-Ramp: Convert stablecoins to fiat currency
The tokens listed in this document are specifically supported for Cobo Payment. While Cobo Portal supports a broader range of tokens, only the stablecoins listed below will be automatically credited when received. Other tokens sent to Payment addresses will not be automatically processed.

Supported pricing currencies

When creating a payment order, you can use the following fiat currencies as the pricing currency (pricing_currency).

Testing

You can use testnet tokens to verify your integration before going live. Testnet transactions do not involve real funds.

Currently, only TRON Nile testnet is supported for testing. More testnets may be added in the future.

​
Important notes

Always verify the network before sendingSending tokens on the wrong network may result in permanent loss of funds. For example:
  • Sending USDC on Polygon to an Ethereum address will not be credited
  • Each Token ID corresponds to a specific chain — always match them exactly
If you or your customer accidentally sends tokens on an unsupported network, contact Cobo Support with the transaction hash for assistance.
Token ID usageWhen integrating with the Cobo API, always use the exact Token ID (such as ETH_USDC or TRON_USDT) as specified in this document. Using incorrect Token IDs will result in API errors.
