# Ethereum Wallet Sign Transaction (beta)

**POST /v1/wallets/{wallet_id}/sign_transaction**

Sign transaction using a managed wallet. Managed wallet means the private key is never exposed to the client and always stored encrypted in our vault. Currently, only Ethereum `ethereum` wallet type signing is supported.

## HTTP Request

`POST /v1/auth/wallets/{wallet_id}/sign_transaction`

## Returns

A successful response returns a `Wallet` object, `signature` property, and `signed_transaction` for the signed transaction. For ethereum transactions, the `signed_transaction` can be used with RPC method `eth_sendRawTransaction` in EVM compatible RPC nodes.
