Filter Tron Smart Contract Events by USDT Contract Address
Retrieve smart contract events emitted by a specific Tron contract address (here, USDT). Returns event arguments, block info, event signature, and transaction hash.
Variations: Replace the smartContractAddress with any TRC-20 contract, or add a smartContractEvent filter to narrow to specific event names.
{
tron {
smartContractEvents(
date: {after: "2023-07-31"}
options: {desc: "block.timestamp.iso8601", limit: 10}

Filter Tron USDT Events by Transfer or Approval Event Names
Filter events for a specific Tron contract to only Transfer and Approval event types, useful for monitoring token movements and allowance changes.
Variations: Edit the in list to include other event names, or remove smartContractEvent to see all events for the contract.
{
tron {
smartContractEvents(
date: {after: "2023-07-31"}
options: {desc: "block.timestamp.iso8601", limit: 10}
smartContractAddress: {is: "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t"}
smartContractEvent: {in: ["Transfer", "Approval"]}
) {

}
block {
