Guides

Practical how-to guides organized by development stage. Each guide solves a specific task with working code.

• AI Coding Agents: Use ICP skills to give AI coding agents accurate canister IDs and tested code patterns.

Build

• Backends: Persist data, make HTTPS outcalls, schedule timers, and generate randomness.
• Canister Calls: Define Candid interfaces, generate type-safe bindings, and call canisters from backends and frontends.
• Frontends: Serve assets, integrate frontend frameworks, configure custom domains, and certify responses.
• Authentication: Add passwordless login and verifiable user identity to your app.

Quality and shipping

• Testing: Write unit tests, run integration tests with PocketIC, and set up end-to-end testing.
• Canister Management: Deploy, upgrade, fund, optimize, and back up canisters.
• Security: Implement access control, DoS prevention, and safe upgrade patterns.

Advanced features

• Digital Assets: Create and integrate with ledgers and wallets using digital asset standards.
• Chain Fusion: Connect canisters to Bitcoin, Ethereum, and Solana and sign cross-chain transactions.
• Governance: Transfer control of your app to your community and govern it through proposals.
