Released on July 8th, 2026
  • Optional validatorUrl in the token and amulet namespaces
the Wallet SDK token and amulet namespaces can now be initialized without a validatorUrl. The only requirement now is to expose just the ledger API and registry urls for amulet and token specific operations. However, users can continue to provide the validatorUrl, if they want to expose their validatorApi to these namespaces as this is an optional parameter. 
import { SDK } from '@canton-network/wallet-sdk'

const sdk = await SDK.create({
    auth: {
        method: 'self_signed',
        issuer: 'unsafe-auth',
        credentials: {
            clientId: 'ledger-api-user',
            clientSecret: 'unsafe',
            audience: 'https://canton.network.global',
            scope: '',
        },
    },
    ledgerClientUrl: localNetStaticConfig.LOCALNET_APP_USER_LEDGER_URL,
    token: {
        registries: [
            new URL('http://localhost:2000/api/validator/v0/scan-proxy'),
        ],
        auth: {
        method: 'self_signed',
        issuer: 'unsafe-auth',
        credentials: {
            clientId: 'ledger-api-user',
            clientSecret: 'unsafe',
            audience: 'https://canton.network.global',
            scope: '',
        },
    },
    },
    amulet: {
        scanApiUrl: 'http://scanapi:8080',
        auth: {
        method: 'self_signed',
        issuer: 'unsafe-auth',
        credentials: {
            clientId: 'ledger-api-user',
            clientSecret: 'unsafe',
            audience: 'https://canton.network.global',
            scope: '',
        },
    },
        registryUrl: 'http://registry:8080',
    },
})
  • Function for retrieving validator party
For certain functions that require a validator operator party, we have provided a method to retrieve given the validator URL 
import { getValidatorParty } from '@canton-network/wallet-sdk'

const validatorParty = await getValidatorParty(
    new URL('http://validatorurl'),
    {
    method: 'self_signed',
    issuer: 'unsafe-auth',
    credentials: {
        clientId: 'ledger-api-user',
        clientSecret: 'unsafe',
        audience: 'https://canton.network.global',
        scope: '',
    }
)
  • Export custom logger types.
exports CustomLogAdapter and the logger adapter types from @canton-network/wallet-sdk, so SDK users can provide their own logging implementation without importing from internal paths.
  • Bug fix: Filter holdings by instrument when creating a transfer.
When instrumentId/instrumentAdmin are passed to sdk.token.transfer.create, the sdk will filter holdings by instrument prior to creating a transfer. Previously, if there was more than one instrument in a party’s holdings, the inputUtxos would have to be passed in as a workaround.
