⚠️ Create a new Tron address (deprecated)

Code samples

POST /api/v1/trx/account

curl -X POST 'https://settla.net/api/v1/trx/account' \
  -H 'X-API-Key: $SETTLA_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
  "index": 0
}'

DEPRECATED, shutdown 2026-12-01. Generates a new TRX address and credentials, i.e. it produces a private key and a mnemonic on the server; the service does not store or handle client keys.

Replacement: build the transaction with POST /api/v1/trx/transactions/create, sign it on your side and submit it with POST /api/v1/trx/transactions/broadcast. Addresses without any private key are available for ETH and BTC via /api/v1/{eth,btc}/xpub.

Body parameter

{
  "index": 0
}

Name	In	Type	Required	Description

» mnemonic	body	string	false	Optional mnemonic phrase.
» index	body	integer	false	Optional derivation index for BIP44 (defaults to legacy derivation if not provided).
