Code samples

POST /api/v1/trx/account/privatekey

curl -X POST 'https://settla.net/api/v1/trx/account/privatekey' \
  -H 'X-API-Key: $SETTLA_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
  "mnemonic": "<12 or 24 words>",
  "index": 0
}'

DEPRECATED, shutdown 2026-12-01. The endpoint accepts a mnemonic and returns a private key; the service does not store or handle client keys.

Replacement: derive keys in your own wallet, 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.
