TRON: blocks and transactions

TRON apps often use TronWeb wallet/* paths. On RpcNode these are invoked as JSON-RPC methods (method string includes the path). Some eth_* aliases may also be available — check the TRON method list in docs.

Steps

  1. Create a tron mainnet endpoint.
  2. Read the tip with wallet/getnowblock (or eth_blockNumber if listed for your endpoint).
  3. Fetch a block with wallet/getblockbynum / wallet/getblockbyid.
  4. Fetch a tx with wallet/gettransactionbyid.
  5. For TRC-20 balances use triggerconstantcontract / eth_call patterns as documented per method.

Tips

  • TRON addresses are base58check (T…); do not send 0x EVM addresses to wallet/* account APIs.
  • Sun units: 1 TRX = 1e6 sun.
  • See /tron in the sidebar for the exact method catalog and credits.
