Tron quickstart - SQD Documentation

Pipes SDK streams filtered Tron data from SQD Portal into TypeScript. This example reads live USDT transfer logs and decodes the transferred amount.

The Pipes CLI currently scaffolds EVM and SVM projects only. Set up Tron and Hyperliquid pipes manually as shown here.

Prerequisites

Node.js 22.15 or later
npm, pnpm, or yarn

Create the project

mkdir tron-pipe && cd tron-pipe
npm init -y
npm pkg set type=module
npm install @subsquid/pipes@beta tsx

Create index.ts:

import { tronPortalStream, tronQuery } from '@subsquid/pipes/tron'

const USDT = 'a614f803b6fd780986a42c78ec9c7f77e6ded13c'
const TRANSFER_TOPIC = 'ddf252ad1be2c89b69c2b068fc378daa952ba7f163c4a11628f55a4df523b3ef'

const stream = tronPortalStream({
  id: 'tron-usdt-transfers',
  portal: 'https://portal.sqd.dev/datasets/tron-mainnet',
  outputs: tronQuery()
    .addFields({
      block: { number: true, timestamp: true },
      log: { logIndex: true, topics: true, data: true },
    })
    .addLogRequest({
      range: { from: 'latest' },
      request: { address: [USDT], topic0: [TRANSFER_TOPIC] },
    }),
})

for await (const { data } of stream) {
  for (const block of data) {
    for (const log of block.logs) {
      if (!log.data || !log.topics?.[1] || !log.topics[2]) continue

      console.log({
        block: block.header.number,
        from: `41${log.topics[1].slice(-40)}`,
        to: `41${log.topics[2].slice(-40)}`,
        amount: BigInt(`0x${log.data}`),
      })
    }
  }
}

Run it:

npx tsx index.ts

Tron Portal hex values do not use a 0x prefix. Transaction addresses use the 21-byte 41... form, while log addresses use the 20-byte form shown above.

Next steps

Handle Tron data for transaction families, address formats, and value types.
Query builder reference for every field and filter.
Use the shared Postgres, ClickHouse, BigQuery, or Parquet target APIs when you are ready to persist the stream.
