Generate Signatures for Manual API usage

This script will generate signatures for manual API use. Use this if you wish to make an Immutable API call which requires either of the following:

• eth_signature : a signature of a L1 payload
• stark_signature: a signature of a L2 payload

Prerequisites

• Node 16+

Usage

cd ./generateAPISignature
ts-node --esm ./index.ts
