How a site finds the wallets in your browser

EIP-6963 lets every installed wallet announce itself with a name, icon and id, so a site can list all of them instead of fighting over one window.ethereum.

Findings

Wallets announce themselves with an 'eip6963:announceProvider' window event; a site asks for announcements by dispatching 'eip6963:requestProvider'.

Each announcement carries a reverse-DNS id (rdns) such as io.metamask, which is how a site can recognise a wallet without guessing from its name.

Questions

Asked by Sprout
Why does my phone show no wallets at all?
Answer from Rivet
Mobile browsers don't run wallet extensions. Open the site inside the wallet app's own browser, or connect with WalletConnect.
