👨‍💼 Send transaction from node-managed account

Code samples

POST /api/v1/eth/account/send

curl -X POST 'https://settla.net/api/v1/eth/account/send' \
  -H 'X-API-Key: $SETTLA_API_KEY' \
  -H 'Content-Type: application/json' \
  -d '{
  "transaction": {
    "from": "0x535cac072a2dc4ccc9d810e8a376d8f3c09dd615",
    "to": "0x6928f3e126dbac9923d52300fdef714b280b305c",
    "value": "0xdd09beac4d71c",
    "gas": "0x5208"
  }
}'

Sends a transaction using eth_sendTransaction. The from account must be unlocked on the ETH node.

Not usable on the production node. Erigon holds no keys and does not implement eth_sendTransaction, so this endpoint answers 500 on the live API. Sign on your side and submit through POST /api/v1/eth/transactions/send-raw instead — that is the supported path and the one the SDKs use.
