TRON

Signing request types

Payload	Use
`tronSendNative`	Transfer TRX.
`tronSendTrc10`	Transfer TRC-10 tokens.
`tronSendTrc20`	Transfer TRC-20 tokens.

To sign transactions you build yourself or messages you format yourself, use raw signing.

Wallet

Create a wallet with networkType: "NETWORK_TYPE_TRON". Activate the address by receiving TRX or a TRC-10 token from an existing account; receiving a TRC-20 token does not activate it. Fund it with TRX for fees and the asset being sent. Transactions consume Bandwidth; TRC-20 transfers also consume Energy. TRX pays when available resources are insufficient.

Send TRX

This TRON Mainnet example sends 1 TRX.

curl -X POST https://api.mpcvault.com/v1/createSigningRequest \
  -H "Content-Type: application/json" \
  -H "x-mtoken: <API_TOKEN>" \
  -d '{
    "vaultUuid": "<VAULT_UUID>",
    "callbackClientSignerPublicKey": "<CLIENT_SIGNER_OPENSSH_PUBLIC_KEY>",
    "broadcastTx": true,
    "tronSendNative": {
      "from": "<YOUR_TRON_ADDRESS>",
      "to": "<RECIPIENT_TRON_ADDRESS>",
      "value": "1000000"
    }
  }'

value is an integer string in sun: 1 TRX = 1,000,000 sun. Use base58check addresses starting with T; from and to are different addresses.

Send BTTOLD (TRC-10)

Replace tronSendNative with this payload in the same request:

{
  "tronSendTrc10": {
    "from": "<YOUR_TRON_ADDRESS>",
    "to": "<RECIPIENT_TRON_ADDRESS>",
    "assetName": "1002000",
    "amount": "1000000"
  }
}

This example sends 1 BTTOLD, the legacy BitTorrent TRC-10 token (assetName: "1002000", six decimals). The newer BTT token uses TRC-20. See BitTorrent’s migration notice.

Send USDT (TRC-20)

Replace tronSendNative with this payload in the same request:

{
  "tronSendTrc20": {
    "from": "<YOUR_TRON_ADDRESS>",
    "to": "<RECIPIENT_TRON_ADDRESS>",
    "contractAddress": "TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t",
    "amount": "1000000"
  }
}

This example sends 1 USDT on TRON Mainnet (six decimals). contractAddress is Tether’s TRON Mainnet USDT contract. Optional feeLimit is a positive integer string in sun that limits contract execution fees; omit it to use MPCVault’s default.

Sign and track

Sign the request. MPCVault broadcasts by default; txHash is the TRON transaction ID (txID). For TRX and TRC-10, query the solidified transaction body. Match the recipient and amount, plus the asset ID for TRC-10; check ret[0].contractRet: "SUCCESS" when present. For USDT and other TRC-20 tokens, query the solidified receipt:

curl -X POST "<TRON_MAINNET_NODE_URL>/walletsolidity/gettransactioninfobyid" \
  -H "Content-Type: application/json" \
  -d '{"value":"<TX_HASH>"}'

Check receipt.result: "SUCCESS", no top-level result: "FAILED", and a Transfer event matching the token contract, sender, recipient and amount. An empty response is not a failure result; keep tracking the original txID. See TRON confirmation semantics.
