EOPEN
TRON Energy API for Exchanges
Reduce USDT TRC-20 withdrawal cost with API-based 65K / 131K Energy rental, webhook status updates, and on-chain delegation proof.
Talk to EOPENWithdrawal Cost Infrastructure for Exchanges
Make every TRC-20 payout predictable
EOPEN helps exchanges rent Energy before high-volume USDT withdrawals, reducing burned TRX while keeping finance and operations teams clear on every order.

Exchange Workflow
Webhook reconciliation
Receive order state, delegation hash, and timeout status without polling your treasury service.
Dedicated commercial terms
High-volume exchanges can negotiate dedicated rates, pool reserves, and response targets.
01
The exchange problem
TRC-20 withdrawals often burn TRX when hot wallets lack Energy. At exchange scale, that turns a network resource issue into a recurring operating cost.
- USDT withdrawals need different Energy packs depending on recipient state.
- Hot wallet operations need predictable timing and audit records.
- Finance teams need a simple cost model across TRX and USDT balances.
02
Worked example: 10,000 daily withdrawals
Take a desk clearing 10,000 warm USDT withdrawals a day. Burning TRX at 6.4 TRX each costs about 64,000 TRX/day — roughly 1,920,000 TRX/month. Renting Energy at a typical 1.5 TRX per transfer brings that to about 15,000 TRX/day — near 450,000 TRX/month. That is well over a million TRX kept on your books each month, and savings of up to 80% on the Energy line that scale linearly as the withdrawal queue grows.
- Warm transfer: ~64,285 Energy (≈ 6.4 TRX burned vs ~1.5 TRX rented).
- Pre-provision 500,000-Energy bulk packs ahead of volatility-driven spikes.
- Map each rental order to the batch it funded for clean reconciliation.
03
How EOPEN fits
Your withdrawal service requests Energy for the sending address, waits for the delegation hash, then releases the USDT transfer. Webhooks keep order state and finance records aligned.
- REST API for Energy order creation.
- Tx hash returned for on-chain verification.
- Bulk pricing and dedicated pool options for high-volume desks.
Next steps
Size a bulk pack to your daily withdrawal volume and turn an unpredictable TRX burn into a forecastable per-transfer line item.
Core API flow
- 1Authenticate your withdrawal service with the exchange API key.
- 2Request a bulk Energy quote sized to the batch (e.g. a 500,000-Energy pack) before the queue drains.
- 3Submit the order and receive Energy delegated to the sending hot wallet; capture the tx hash.
- 4Release withdrawals at the rented rate (~1.5 TRX each) instead of burning ~6.4 TRX, and reconcile by order ID.
Exchange FAQ
Can EOPEN support exchange withdrawal spikes?
Yes. Enterprise accounts can discuss reserved pool capacity and operating limits before production rollout.
Can we settle in USDT instead of TRX?
Account balances support both TRX and USDT, which keeps exchange finance reconciliation simpler.
Do we need to custody user assets with EOPEN?
No. EOPEN delegates Energy to your TRON address. Your withdrawal keys and assets remain under your control.
Migration & verifiability
Why do I see different field names in old docs vs new docs?
Field naming and migration details are maintained on docs.eopen.io. This page keeps only the exchange scenario overview.
