TRON
Unified API + TRON Integration Workflow
In the following guide, the integration process for the tron chain is covered. TRON integration aligns with the general Unified API process but with network-specific parameters.
Get an authentication token to start using the Unified API.
Request examples are provided using cURL.
To check the integration guides for other chains, refer to the Networks Supported section.
Key TRON-specific details
chain— always set totronfor TRON-related requests.network— environment in which the transaction is processed:mainnetortestnet-nile.stakerAddress— TRON account address initiating staking, voting or withdrawal transactions.amount— amount of tokens in SUN (1 TRX = 10⁶ SUN). Note that only TRX (SUN) can be staked, since USDT (TRC-20) is not natively stakeable.
Staking flow
1. Create freezing request
Send a POST request to /api/v1/unified/staking/stake.
Example request (for testnet-nile network):
curl --request POST \
--url https://api-test.p2p.org/api/v1/unified/staking/stake \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer <token>' \
