Builder Toolkit

Start here when you want to see Nitrolite working before reading every page. Try the live apps, inspect their source, then use the SDK and migration docs when you are ready to build.

Live Examples

Shared checkout

Co-Sign Checkout

Two participants create a shared cart, co-sign checkout actions, move funds into an app session, propose purchases, close the cart, and withdraw remaining shared-wallet funds.

Upcoming Tools

Coming soon

Nitrolite Playground

Manage channels and inspect active app sessions from one UI. App-session management will be available after the playground deployment is ready for builders.

Deployment pending

Coming soon

Yellow SDK MCP

Structured SDK, protocol, RPC, examples, and migration context for AI coding tools. This should help teams build with Yellow SDK with fewer hallucinated method shapes.

NPM package pending

Coming soon

Faucet App

Get testnet assets for the v1 builder flow without leaving the Nitrolite docs path. This will be linked here once the faucet deployment is ready.
