How it works

1Shot walkthrough

Provision & Fund Your Key

Create an API key then fund your escrow wallet on your target network (ETH, BASE, AVALANCHE, and more) 

Configure Your Transaction

Enter a contract address and function call to generate a private API endpoint—transactions are signed, submitted and monitored automatically.

Call the API

Use your favorite HTTP library (cURL, Requests, Axios, etc.) to call your endpoint and execute the transaction; no client-side keys or signing. 

Monitor and Confirm

1Shot handles the transaction lifecycle—optional webhooks notify your application when transactions are confirmed.
