DApp Browser migration

We are in the process of deprecating the DApp Browser.

Ledger Live will now support injecting a compatible provider in the webview.

Deprecations

GitHub - LedgerHQ/iframe-provider (opens in a new tab)
GitHub - LedgerHQ/eth-dapp-browser (opens in a new tab)
params field in the manifest used by Ledger Live (replaced by the dapp field)

Changes

Ledger Live will now inject the needed provider in the WebView directly avoiding the need for an iframe like the eth-dapp-browser

The new provider is EIP 6963 compliant if there is a need for it but you can also use the injected window.ethereum

The provider exposes a boolean provider.isLedgerLive to inform when you are in the Ledger Live environment, in that case we expect the dApp to auto connect using this provider, thus improving the user experience and avoid unnecessary clicks

Manifest for dApps can now use the url field directly instead of params.dappUrl and must use the dapp field instead of the params for the provider, networks and nanoApp fields

Ledger Live supported versions

Desktop: 2.79
Mobile: Next release
