Substreak Pay

Get paid on-chain. Nobody in the middle.

Payment links, game invoices and subscriptions where the money moves from the payer's wallet straight to yours. Substreak watches the chain and tells you when it arrived.

Create a payment link My subscriptions

Links and checkouts

Create a link or QR code for an exact amount of ENJ, an Enjin token or NFT, or a token on Ethereum-style chains and Solana. The payer connects their wallet and sends straight to you.

Confirmed on-chain, then told

A payment counts only once it is confirmed on-chain. Then Substreak marks it paid, can start your automations and notifies your server with a signed webhook.

Subscriptions you control

Subscribers allow a capped amount that they can switch off any time, and one payment is collected each period. For coins like ENJ they get a reminder and pay with one tap instead.

Connect your wallet

Payment links belong to the wallet you sign in with. Connecting sends nothing, and your keys never leave your wallet.

Invoices from your game or app

For developers: create a request with an API key that can write, send the player to its checkout link, and your webhook hears about the payment once it is confirmed.
