Zama Mainnet API Key Request

This form is for builders who want to deploy a confidential dApp on Ethereum mainnet using the Zama hosted Relayer. Mainnet requests require an API key. Request yours here.

What you get

* A mainnet API key for the Zama hosted Relayer.
* Relayer access is free for admitted projects; you pay only your own mainnet gas. * A 15-minute call with the Zama team before your key is issued.

Requirements

* A working confidential dApp on Sepolia (smart contract + frontend), or a previous Zama Developer Program submission.
* An identified team: real names, GitHub and X profiles, one contact email. * A clear plan for what goes to mainnet and why it needs confidentiality. * A backend that proxies Relayer calls, so the key never ships in your frontend.

How it works

1. Request a key with this form (about 10 minutes). 2. We review requests on a rolling basis. 3. Admitted builders get a 15-minute verification call. 4. Your key is issued within about a week of your request.
