What is it?

Nautilus Wallet is an open-source browser extension wallet for the Ergo platform, available for Chrome and Firefox. It lets users manage standard wallets, read-only wallets and hardware wallets side by side from one interface.

The wallet can sign transactions with a Ledger device, so private keys stay on the hardware. It also acts as a dApp Connector, exposing the EIP-12 compatible API that Ergo dApps use to request connections and transactions.

NFT collectibles are shown in a sandboxed gallery, which keeps untrusted token content isolated from the wallet itself. The project supports mainnet and testnet builds and includes unit, type, end-to-end and lint checks.
