Introduction ​

The Code payments platform makes accepting small payments on the web simple. It’s open, permissionless, and requires just a few lines of code—no sign-up necessary.

After a decade of building consumer platforms and developer tools, we realized traditional payment systems are too limiting—they offer only large, one-way payments, involve complex onboarding, and charge high fees. The Code SDK lets you embed a "Pay with Code" button to charge as little as 5 cents per transaction, with only a flat 1-penny fee to cover blockchain costs.

What is Code? ​

Code is the mobile wallet app used for payments. It offers the benefits of self-custodial crypto—global, secure, and simple—without the hassle of managing private keys, gas fees, or slow transactions. Built on the Solana blockchain and powered by the Code Sequencer, Code delivers an instant, global, and private payments experience.

What is the Code SDK? ​

It’s a collection of JavaScript, TypeScript, Go, Python, and PHP packages that let you integrate Code into your website or web app—on both the client and server sides.

The SDK provides a simple interface to the Code API.

What is the Code API? ​

The Code API is a gRPC-based API that lets you interact with the Code Sequencer. It’s used to create payment intents, verify payments, and more.
