Token standard
TRC-20 Token Standard
TRC-20 is a token standard that allows the creation of tokens on the TRON network. The TRC-20 standard requires the implementation of several functions so that the contract can work correctly with the protocol.
Work with TRC-20 tokens via the CryptoAPIs API
Read TRC-20 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-20 token transfer history for any token contract or address, with pagination and real-time updates.
Token balances
Read current TRC-20 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.
The TRC-20 contract standard
In order to swap, transfer, share token and be supported by digital wallets, all the TRC-20 tokens follow a series of specifications which include 6 required items and 3 optional items.

BEP-20Frequently Asked Questions
Which blockchain does TRC-20 run on?
TRC-20 settles on Tron. Tron meters execution in bandwidth and energy rather than gas, so a TRC-20 transfer's cost model is different from an ERC-20 one even though the token interface looks familiar.
What kind of token standard is TRC-20?
It is a fungible-token interface, Tron's counterpart to ERC-20.
Can I test TRC-20 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-20 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-20 data cost?
It depends on the endpoint family rather than on TRC-20 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-20 tokens on CryptoAPIs
Now that you know what TRC-20 is, integrate it: read TRC-20 token transfers, balances, and contract metadata across supported chains through one REST API.
