ERA is the companion app for the ERA hardware wallet. Your private keys are generated on the device and never leave it — the app is watch-only and non-custodial, so you stay in full control of your crypto at all times.

Every transaction is signed on your hardware wallet and confirmed by you on its screen. The app and the device communicate through air-gapped QR codes and NFC, so your keys are never exposed to the internet, your phone, or us.

WHY ERA
• Non-custodial — you hold your keys, we never do
• Air-gapped signing over QR and NFC — keys stay offline on the device
• Watch-only app — no seed phrase or private key ever touches your phone
• No sign-up, no email, no account — just pair your device and go

WHAT YOU CAN DO
• Track your whole portfolio with live balances and USD values
• View full transaction history across every chain
• Receive with a tap and share your addresses as QR codes
• Send crypto — built, reviewed, and signed on your hardware device
• Swap tokens within and across chains through an integrated aggregator
• Buy crypto with fiat through our on-ramp partner
• Connect to dApps with WalletConnect and sign securely on the device
• Manage multiple accounts and a personal address book
• Keep your device firmware up to date

SUPPORTED NETWORKS
Bitcoin, Ethereum and leading EVM networks (Arbitrum, Optimism, Base, Polygon, BNB Chain, Avalanche, Gnosis, zkSync, Aurora, Kaia), Solana and Tron — with more on the way.

SECURITY FIRST
• Private keys are generated and stored only on the ERA hardware wallet
• Transactions are signed offline and verified on the device screen
• App access is protected by a PIN and optional biometric unlock
• Swaps and purchases are handled by licensed third-party providers; ERA never takes custody of your funds

IMPORTANT
ERA is a companion app and requires an ERA hardware wallet to sign transactions and manage funds. Without the device you can explore the interface, but sending, swapping, and signing require your hardware wallet.

Own your keys, own your crypto — with ERA.
