Usage Patterns

All commands are available through the SDK instance:

// Get SDK instance
const sdk = window.movementSDK;

// Or use React hook
const { sdk } = useMovementSDK();

// Call command
const result = await sdk.sendTransaction({...});

Response Handling

Commands return promises that resolve with results or reject with errors:

try {
  const result = await sdk.sendTransaction({...});
  console.log('Success:', result);
} catch (error) {
  console.error('Error:', error.message);
}

See Responses for detailed error handling patterns.

Rate Limits

Commands are rate-limited to prevent abuse:

• Transactions: 300 per day per user
• Notifications: 50 per day per user
• Other commands: 1000 per hour

Rate limit errors return status code 429.
