# DApp Browser v3 migration

We are in the process of deprecating the dApp Browser live-app v1 and v2.

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

## Deprecations

- [GitHub - LedgerHQ/iframe-provider](https://github.com/LedgerHQ/iframe-provider)
- [GitHub - LedgerHQ/eth-dapp-browser](https://github.com/LedgerHQ/eth-dapp-browser)
- `params` field in the manifest used by  (replaced by the `dapp` field)

## Changes

Ledger Wallet 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  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 Wallet supported versions

- Desktop: 2.79
- Mobile: Next release
