Everything you need to build on Canton.

Your first Canton app in four steps

1. Get to know Canton

   Canton's privacy model, parties and how synchronization works.

2. Learn Daml

   Daml, Canton's smart contract language: templates, signatories, observers and choices.

3. Run the Quickstart

   Bring up a complete Canton application locally with a few commands.

4. Connect Loop Wallet

   Let your users sign transactions with Loop Wallet, the official HackTrail wallet.

Set up your local environment in a few commands

The Canton Network Quickstart runs Canton, Daml and a sample application locally on Docker. First install the prerequisites from the official guide (Docker, direnv and so on), then:

$ git clone https://github.com/digital-asset/cn-quickstart.git
$ cd cn-quickstart
$ direnv allow
$ cd quickstart
$ make setup   # configure the environment
$ make build   # build the application
$ make start   # start the Canton services

We recommend allocating at least 8 GB of memory to Docker. Run make help to list all targets.

Connect with Loop Wallet

The Loop SDK lets your dApp connect to a Loop account. Users sign transactions in Loop Wallet on mobile or in the browser, and the whole interaction stays inside your dApp.

// npm install @fivenorth/loop-sdk
import { loop } from '@fivenorth/loop-sdk';

loop.init({
  appName: 'HackTrail dApp',
  network: 'devnet',            // 'local' | 'devnet' | 'mainnet'
  onAccept: (provider) => console.log(provider.party_id),
  onReject: () => console.log('rejected'),
});

loop.connect();                     // opens the connection window with a QR code

After HackTrail: a Canton Foundation grant

The Canton Foundation's Protocol Development Fund supports work that brings long-term value to the whole network. Strong HackTrail projects can apply to this program.

• Funding areas: core research and development, developer tools, security and audits, reference implementations, DeFi liquidity support and critical infrastructure.
• You apply by opening a pull request in the Foundation's proposal repo on GitHub.
• If you are not a Foundation member, your proposal needs a champion from the Tech & Ops Committee.
• Payments are made in Canton Coin as milestones are completed.
