👋 Welcome to Tronfuel

Tronfuel is your gateway to the Tron blockchain — with all the complexity removed.

We provide developers and businesses with the tools to build, sign, send, and monitor Tron transactions while automatically managing resource delegation (energy, bandwidth) behind the scenes.

#💡 What We Do

Interacting with the Tron blockchain can be tricky due to:

Limited bandwidth and energy resources
Inconsistent transaction fees
Contract reverts due to missing resources
Incomplete monitoring of transaction status

Tronfuel solves all of this:

✅ Automatically estimates and provisions bandwidth and energy
✅ Offers per-request billing from your internal wallet
✅ Provides webhooks for real-time status updates
✅ Supports TRX, TRC10, TRC20, and TRC721 transactions
✅ Enables both advanced and simple usage modes

#🔁 Workflow Overview

Whether you’re sending TRX or smart contract calls, your basic workflow looks like this:

#🛠 Advanced Mode (Full Control)

Build the transaction payload
Sign it with your private key locally
Send the signed transaction via our API
Receive webhook notifications as it progresses

#⚡ Simple Mode (All-in-One)

Submit one payload including your private key
We build, sign, send, and monitor for you
You get full webhook tracking + resource coverage

Code examples for signing transactions securely in PHP, Python, Go, Java, and JavaScript.

#🚀 Send Transactions

Send signed transactions to the blockchain using Tronfuel’s send endpoint. We manage energy, bandwidth, and errors.

#📈 Fee Estimator

Estimate energy, bandwidth, and account activation costs for your transaction before sending.

#⚡ Simple Mode

Let us build, sign, and send the transaction for you. Best for quick setups and low-friction scripts.

#📬 Webhooks

Get real-time updates for every transaction event: broadcasted, confirmed, or failed. Includes signature verification.

#🧪 Test on Testnet First

We support both Mainnet and Nile Testnet. Use the X-Network header to switch between environments.

Example:

 1X-Network: nile

#🔐 Security First

We never store private keys unless you send them in Simple Mode. Webhook messages are signed. We handle resource allocation via internal TRX balances, giving you predictable fees and reliable delivery.
