Loop SDK

Loop SDK allows dApps to connect to a Loop account.

What is Loop SDK?

Loop SDK is a lightweight JavaScript client that allows dApps to securely connect to the Loop wallet.
It handles the connection flow, performs session validation, and provides a Provider object so your application can fetch holdings, query DAML contracts, submit transactions, and sign messages.

Limitation

Currently, the SDK only supports DAML transactions from the built-in Splice DAR files and Utility app DAR files.

There is no plan to upload or support third-party DAR files at this time.

Security Considerations

The Loop SDK is designed so your dApp never handles private keys directly.
For best security:

  • Do not request or store private keys.
  • Avoid persisting sensitive fields (e.g., authToken, party_id, email) outside memory.
  • Always use HTTPS.
  • Verify user identity on your backend before performing sensitive actions.
