Tron: chain ID, RPC URLs and explorers

The main Tron RPC endpoint is TronGrid: https://api.trongrid.io for Tron's own HTTP API and https://api.trongrid.io/jsonrpc for Ethereum-style JSON-RPC, and both answered our test today. TRX trades at $0.3173 on CoinGecko, and DefiLlama counts $92.2 billion of USDT on Tron.

Tron RPC and API Endpoints Tested Today

Tron RPC access comes in two styles, and we tested both on November 8, 2026: the native HTTP API that Tron wallets and exchanges use, and a JSON-RPC layer for Ethereum tools. For the HTTP API we called wallet/getnowblock and got a current block back. For JSON-RPC we called eth_chainId and compared the hex.

https://api.trongrid.io: TronGrid HTTP API, from Tron's networks page.
https://api.trongrid.io/jsonrpc: TronGrid JSON-RPC, returned 0x2b6653dc.
https://tron-rpc.publicnode.com: PublicNode HTTP API, returned a current block.²
https://tron-evm-rpc.publicnode.com: PublicNode JSON-RPC, returned 0x2b6653dc.

An Ankr endpoint that chainid.network lists returned a 403 error asking for an API key, so it is left off.

Where Tron's Chain ID 728126428 Comes From

Tron's chain ID 728126428 is not a number anyone picked: Tron's docs say eth_chainId returns the last 4 bytes of the genesis block hash.³ The mainnet genesis block ID ends in 2b6653dc, and 0x2b6653dc is 728126428 in decimal.

chainid.network lists Tron Mainnet under the same 728126428, so the two sources agree.⁴ The number matters only to Ethereum-style tools that talk to the JSON-RPC layer. Tron's own transactions use TAPOS for replay protection, a reference to a recent block, and accounts carry no nonce. Most networks in the chains hub need no such derivation, because their IDs were simply assigned.

Why Tron Is Not an EVM Chain in Your Wallet

Tron is not an EVM chain in your wallet, even though its virtual machine runs most Solidity contracts unchanged. Tron's docs call the TRON Virtual Machine fundamentally compatible with the EVM, then list the gaps: Energy instead of gas, no EIP-1559 fee market and no account nonce.⁵

Addresses are the part users see. A Tron address is 21 bytes starting with 41, shown in wallets as 34 characters starting with T.⁶ Tron's JSON-RPC does not accept those T addresses at all, and Tron's docs say JSON-RPC is not a full replacement for the HTTP API. The wallet address page compares the formats.

Tronscan, the Tron Mainnet Explorer

Tronscan at tronscan.org is the Tron mainnet explorer that Tron's docs list, and the testnets have their own copies at shasta.tronscan.org and nile.tronscan.org. Tether links its Tron contract on Tronscan too.

Official USDT TRC20 Contract on Tron

The official USDT TRC20 contract on Tron is TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t, as Tether lists it, and that token holds 52.1% of all USDT today.⁷ The USDT TRC20 guide covers sending it.

Circle's USDC address list has no Tron entry as of November 8, 2026. Circle stopped minting USDC on Tron in February 2024 and gave Circle Mint customers until February 2025 to move it to other chains, The Block reported.

How Tron Produces Blocks

Tron produces blocks with Delegated Proof of Stake: stakers vote, and the top 27 candidates, called Super Representatives, take turns making a block every 3 seconds.⁹ A block is final, which Tron calls solidified, once at least 19 of them have built on it, typically in about a minute.

Block 1 of the current mainnet is stamped June 25, 2018, according to TronGrid.

Tron Fees: Bandwidth and Energy

Tron fees work through two resources, Bandwidth and Energy. Bandwidth pays for a transaction's size, and every account gets 600 free each day; Energy pays for contract calls and has no free amount.¹⁰ A USDT transfer is a contract call, so a wallet without staked Energy burns TRX for it. The TRC20 explainer walks through that cost.

Questions People Ask About Tron: chain ID, RPC URLs and explorers

These are the questions people ask next about Tron: chain ID, RPC URLs and explorers.

What is the Tron RPC URL?

The Tron RPC URL most tools use is https://api.trongrid.io for the native HTTP API, or https://api.trongrid.io/jsonrpc for Ethereum-style JSON-RPC. Both come from Tron's docs and both passed our test today. PublicNode runs free alternatives.

What is the Tron network chain ID?

The Tron network chain ID is 728126428, or 0x2b6653dc in hex, as eth_chainId returns it on TronGrid. Tron's docs derive it from the last 4 bytes of the genesis block hash, and chainid.network lists the same number.

Is the Tron network an EVM chain?

The Tron network is not an EVM chain in the wallet sense, although its virtual machine runs most Solidity code. Tron uses T addresses, meters fees in Energy and Bandwidth instead of gas, and relies on TAPOS instead of a nonce, so it needs a wallet with Tron support.

Does Tron have a testnet?

Tron has two testnets, Shasta and Nile, each with its own TronGrid endpoint and Tronscan explorer. Shasta's HTTP API is https://api.shasta.trongrid.io and Nile's is https://nile.trongrid.io, according to Tron's networks page.
