Code is an open, self-custodial payments protocol and mobile wallet built on the Solana blockchain. Its SDK lets any web developer embed a "Pay with Code" button and accept permissionless micropayments — as little as 5 cents per transaction plus a flat 1-cent blockchain fee — with no sign-up required and just a few lines of code. The API is defined as gRPC/Protobuf services (code-protobuf-api): clients sign transaction intents with a self-custodial Ed25519 keypair, payments are created as idempotent payment intents, and completion is confirmed server-side or via JWT-signed webhooks. The entire stack — SDKs (JavaScript, Go, Python, PHP), the Code VM, and the on-chain Solana programs — is open source under the code-payments GitHub org. Code was seeded by Union Square Ventures.
