• Allocate parties with an external keypair
• Read active contracts on the ledger
• Decode and validate prepared transactions
• Sign and submit transactions

Installation

Install the SDK with your package manager of choice

$ npm install @canton-network/wallet-sdk

or

$ pnpm add @canton-network/wallet-sdk

Getting Started

Import and configure the SDK:

import { SDK } from '@canton-network/wallet-sdk'

const auth: TokenProviderConfig = {
    method: 'self_signed',
    issuer: 'unsafe-auth',
    credentials: {
        clientId: 'ledger-api-user',
        clientSecret: 'unsafe',
        audience: 'https://canton.network.global',
        scope: '',
    },
}

const sdk = await SDK.create({
    auth,
    ledgerClientUrl: 'http:ledgerClientHost:port',
})

//alternatively, if you have a Provider with LedgerApi capabilities

const sdk = await SDK.create(provider)
