From zero to first confirmed payment

Pick your stack, paste your payout addresses, copy three files. No account required. Your keys stay on your server — we just watch the chain and ping your webhook.

Where will you integrate?

We’ll generate code that’s drop-in for your stack. You can change this later.

Which chains will you accept?

Paste the payout address for each chain. These stay in your .env — we never see your keys.

Stays in your code
How this works. Customers send to your address from any wallet they own. We watch the chain, verify the on-chain transfer, and POST a signed webhook to your server. ZettaPay never holds funds. Read the wallet-less spec →

Copy these 3 files

Drop them into your repo. Pubkeys are already filled in. Every line has a comment so you can read it before you trust it.

Manual checklist · works today


          

            
1

              
SDK installed

              
Run npm ls @zettapay/sdk (or your package manager equivalent) and confirm a version appears.

            

            
2

              
Env vars are set

              
In your dev shell: echo $ZETTAPAY_WEBHOOK_SECRET should print a hex string. If empty, restart your dev server after editing .env.

            

            
3

              
Pubkeys reach the chain listener

              
Curl our public listener:
              
curl https://zettapay.vercel.app/api/status

              Status should return ok with the chains you selected listed under enabled.

            

            
4

              
Webhook endpoint reachable

              
From your dev shell run the sample POST shown in the generated handler comments. Your handler should log a 200 OK.

            

            
5

              
Signature verification works

              
Tamper one byte of the body and re-POST — your handler should reject with 401. That’s Ed25519 doing its job. Your webhook secret never leaves your server.

You’re live.

                
Send a test payment to your address from any wallet. The next confirmed transfer will POST to your webhook within seconds. Open the live status page to watch listener uptime.

          ZettaPay is 100% open-source.
          Every endpoint, every signature, every line of code is on GitHub. We never custody — payments flow directly between your customer’s wallet and your address.
