signing

Example: signing

Two sample scripts demonstrating transaction and payload signing via the Turnkey API.

sign_raw_payload

Signs an arbitrary hex-encoded payload using Keccak256 hashing.

1/ Setup

Copy .env.example to .env and fill in the values:

cp examples/signing/sign_raw_payload/.env.example examples/signing/sign_raw_payload/.env

2/ Running

set -a && source examples/signing/sign_raw_payload/.env && set +a && go run ./examples/signing/sign_raw_payload

Prints the signature r, s, and v values on success.

---

sign_transaction

Signs an Ethereum transaction (EIP-1559) using a Turnkey wallet address or private key ID.

1/ Setup

Follow the Quickstart to get your API key and organization ID, then create a wallet to sign with.

Copy .env.example to .env and fill in the values:

cp examples/signing/sign_transaction/.env.example examples/signing/sign_transaction/.env

TURNKEY_UNSIGNED_TRANSACTION defaults to an EIP-1559 transaction sending 0 ETH to the zero address on mainnet if not set.

2/ Running

set -a && source examples/signing/sign_transaction/.env && set +a && go run ./examples/signing/sign_transaction

Prints the signed transaction hex on success.
