Hands-on tutorials

Pick a starting point. Each tutorial is self-contained, takes under an hour, and ends with running code or a deployed contract.

Install the wallet, claim from the faucet, send 1 QCH on Channel 1, and watch the SpendAndRotate event fire.

Walk the parent → child Merkle tree, derive a child manually, and verify a proof against the on-chain root.

Build the Counter contract end-to-end with Hardhat, deploy to testnet, and call it from the TypeScript SDK.

Stream new blocks via the websocket, hydrate transaction details from RPC, and render the SpendAndRotate trace.

Provision a Hetzner AX42, install the node binary, register stake, and watch the first block reward arrive.

Drop @quanchain/sdk into a Next.js app, fall back to eth_* compat where needed, and feature-flag composite signing.

Detect a leak, fire a composite-signed recovery on Channel 2, and migrate to a higher security level.

Upload a 600 KB JSON blob to Channel 3, reference it from a Channel 2 contract, and verify integrity on read.
