# Canton Wallet SDK 1.5.0 improves token-lock handling

**By [CantonNews](https://cantonnews.org/author/cantonnews), Editorial Team** · Published 11 September 2026 · TECHNOLOGY

> Canton’s wallet developer toolkit has been updated with better handling of expiring token locks, a public-registry access fix and a new trade example.

[Canton Wallet SDK 1.5.0 has been released](https://github.com/canton-network/wallet/releases/tag/@canton-network/wallet-sdk@1.5.0), updating the tools developers use to connect wallets and applications to the network.

One change concerns tokens locked for a set period. The toolkit now recognises locks whose expiry is expressed as a duration after the holding was created. The fix lets eligible holdings with expired locks count toward available balances and fund transfers. The [implementation and tests](https://github.com/canton-network/wallet/pull/2398) set out how the expiry is calculated.

Another fix lets developers [query public token registries without attaching authentication](https://github.com/canton-network/wallet/pull/2415). Developers can select this option for public services that do not require a login; authenticated access remains the default.

The September 9 release also adds a [multi-synchronizer trade example](https://github.com/canton-network/wallet/pull/1622). Synchronizers coordinate transactions between participants, and the example gives developers code for a trade involving more than one of them.

Version 1.5.0 is available through the project’s official repository, alongside its release notes and updated supporting packages.
