Quick Reference

Adding New Chains

See: references/rules/adding-chains.md

Key steps:

1. Implement chain core logic in packages/core/src/chains/mychain/
2. Add chain configuration in packages/shared/src/config/chains/
3. Update UI components for chain-specific features
4. Add comprehensive tests

Reference implementations:

• EVM chains: packages/core/src/chains/evm/
• Bitcoin: packages/core/src/chains/btc/
• Solana: packages/core/src/chains/sol/

Adding WebSocket Events

See: references/rules/adding-socket-events.md

Key steps:

1. Define event name in EAppSocketEventNames enum
2. Define payload type interface with msgId: string
3. Add event handler in PushProviderWebSocket.initWebSocket()
4. Always acknowledge messages via ackNotificationMessage

this.socket.on(EAppSocketEventNames.myEvent, (payload: IMyPayload) => {
  void this.backgroundApi.serviceNotification.ackNotificationMessage({
    msgId: payload.msgId,
    action: ENotificationPushMessageAckAction.arrived,
  });
  void this.backgroundApi.someService.handleEvent(payload);
});

See: references/rules/notification-system.md

Notification modes:

Key files:

• Service: packages/kit-bg/src/services/ServiceNotification/ServiceNotification.ts

• Types: packages/shared/types/notification.ts

Pages & Routes

See: references/rules/page-and-route.md
