ERA is an air-gapped hardware wallet that shows you what you sign.
Most hardware wallets ask you to approve raw hex. ERA Lens™ decodes the transaction on the device itself, offline — plain language, no registry lookup, no network call, no blind trust. Ten independent wallets live on one device, isolated from one another. Nothing crosses the air gap but a QR code: no USB, no Bluetooth (EIP-4527).
This publisher hosts the official Dart and Flutter SDKs for that device: linking a wallet from its export, building the sign requests it understands, verifying the signatures that come back, and deriving addresses locally for every chain it supports.
