Token standard
TRC-721 NFT Standard
TRC-721 is a standard interface for issuing non-fungible tokens (NFT) on the TRON network. Tokens created on the TRC-721 standard can represent any digital type of tangible assets in the real world. TRC-721 is fully compatible with ERC-721.
Work with TRC-721 tokens via the CryptoAPIs API
Read TRC-721 token transfers, balances, and metadata across the chains CryptoAPIs supports — through one unified REST API, with no node to run.
Token transfers
List full TRC-721 token transfer history for any token contract or address, with pagination and real-time updates.
Token balances
Read current TRC-721 token holdings for any address in a single call.
Contract metadata
Get token contract details — symbol, name, decimals, and total supply — for any supported token.
More opportunities for developers
The TRC-721 standard has as important role for the TRON blockchain as TRC-20. It provides many opportunities for developers to create new applications based on the blockchain, and to track and transfer NFTs on TRON.

BEP-20Frequently Asked Questions
Which blockchain does TRC-721 run on?
TRC-721 settles on Tron. It keeps ERC-721's per-token-id semantics while settling on Tron, so the same NFT logic applies but the fee model and address format do not.
What kind of token standard is TRC-721?
It is a non-fungible interface, Tron's counterpart to ERC-721.
Can I test TRC-721 without spending real funds?
Yes — the same endpoints serve Tron's Nile testnet, so you can build and verify an integration end to end before you touch mainnet.
How do I read TRC-721 balances and transfers?
Use Address Latest for current state and recent activity — it needs no setup and answers for roughly the last 14 days. For a full history, Address History requires the address to be synced first, which then bills per address per day for as long as it stays synced.
What does reading TRC-721 data cost?
It depends on the endpoint family rather than on TRC-721 itself: single-record calls are charged per request, while list endpoints are charged per page returned, and a synced address adds a daily monitoring charge. The pricing calculator has the current per-chain figures.
Build with TRC-721 tokens on CryptoAPIs
Now that you know what TRC-721 is, integrate it: read TRC-721 token transfers, balances, and contract metadata across supported chains through one REST API.
