Getting Started

1. Install the FabricVault extension from the Chrome Web Store (link TBD)

2. Configure at least one peer and one identity in the extension dashboard

3. Run the JSON-RPC gateway alongside your Fabric network:

   npx @fabric-vault/gateway

4. Use the SDK in your dApp to connect:

   import { waitForProvider, FabricVaultClient } from "@fabric-vault/sdk"
   
   const { info, provider } = await waitForProvider()
   const client = new FabricVaultClient(provider, info)
   const identities = await client.connect()

See the Getting Started guide for full setup instructions.
