TronFuel — Gasless Transactions API for TRON
Non-custodial energy & bandwidth rental → Let users transact without TRX • Save up to ~75% on fees
_______________________________________________________________________________ _
Why TronFuel?
- Gasless UX: Let users send TRC-20 tokens and interact with smart contracts without holding TRX.
- Meaningful savings: Pay-as-you-go resource rental typically reduces costs vs. default flows (developers report up to 75% lower transaction fees).
- Non-custodial & secure: Transactions are built unsigned and signed locally — private keys never leave the client.
- Developer friendly: REST API, webhooks, code samples and SDK examples for common Tron stacks (quick integration).
- Fits many use cases: Wallets, NFT marketplaces, games, DeFi, airdrops and remittance/payment apps.
How it works — 4 simple steps
- 1) Build an unsigned Tron transaction payload in your app (e.g. TRC-20 transfer).
- 2) Call TronFuel's estimate endpoint to preview energy & bandwidth needs and cost savings.
- 3) User signs the unsigned payload locally (private key never shared).
- 4) Submit the signed transaction to TronFuel — we rent resources and relay/broadcast. Track status via webhooks or API.
Quick integration (conceptual)]
Code:
# pseudo-code example (concept)
unsigned_tx = build_tron_tx(...)
estimate = POST https://tronfuel.dev/api/v1/estimate { unsigned_tx }
signed_tx = user_sign(unsigned_tx)
resp = POST https://tronfuel.dev/api/v1/relay { signed_tx, api_key }
# track via webhook or GET /status/{txid}
Security & reliability
- Local signing enforced — TronFuel never stores private keys.
- All API traffic is TLS encrypted; webhook payloads include HMAC signatures for authenticity.
- Contact us for SLA/enterprise onboarding and volume plans.
Pricing & trial
Pay-as-you-go pricing based on consumed energy/bandwidth. Reach out for sandbox access and trial API credits for evaluation or proof-of-concept integrations.
Common integrations / proven use cases
- Wallets: Increase transactions and reduce churn by removing TRX friction for users.
- NFT marketplaces & Games: Enable minting/trading with a smoother UX and lower costs.
- DeFi / Remittance: Predictable, lower per-transfer cost for high-volume flows.
- Airdrops & token distributions: Bulk transfers without staking TRX or holding resources long-term.
