If you care about keeping your crypto truly secure without constantly second-guessing what you’re approving, hardware wallets like ERA Wallet have been turning heads for a reason. Built from the ground up as a fully air-gapped device that communicates only via QR codes (no USB, no Bluetooth, no Wi-Fi ever), it already stood out with its on-device decoding through ERA Lens™ and support for up to 10 independent seed phrases on a single slim card-sized device.
Now, ERA has just shipped its biggest firmware update to date — and it’s a game-changer for anyone holding assets across multiple ecosystems.
Massive Expansion: 37 New Blockchains, All Air-Gapped
Previously, ERA supported Bitcoin, Ethereum & EVM L2s, Solana, and Tron. This release significantly broadens the horizon:
- Bitcoin family: Litecoin, Dogecoin, Dash, Bitcoin Cash
- Major L1s: Cardano (ADA), XRP, TON, Sui
- Full Cosmos ecosystem in one go: Cosmos Hub, Osmosis, Celestia, Injective, Sei, THORChain, and 24 more networks
Every single one of these new chains works 100% air-gapped via QR code. You scan the transaction QR from your software wallet (MetaMask, Rabby, OKX, or any EIP-4527 compatible app), review everything on the device’s e-ink screen, and sign — all without the device ever touching a network or cable.
This level of broad multi-chain support while maintaining true air-gapped security is rare. Whether you’re deep into DeFi on Cosmos or simply want to hold your ADA or TON offline with the same peace of mind as your Bitcoin, you no longer have to compromise.
Quick Sign — Multi-Wallet Signing, Finally Simple
One of the most practical improvements in this update is Quick Sign.
ERA already lets you store up to 10 completely independent seed phrases on one device (perfect for separating cold storage, DeFi activity, trading wallets, etc.). Until now, when a transaction arrived, you had to manually figure out which of your 10 wallets it belonged to.
With Quick Sign it’s now effortless:
Unlock the device → Press Sign → The wallet automatically detects the correct seed phrase and takes you straight to the review screen.
Same rock-solid air-gapped security, dramatically less friction. If you manage multiple wallets (and most of us do these days), this alone is worth the update.
See What You Sign — Every Single Time
Blind signing has cost users and protocols billions. ERA’s ERA Lens™ already decodes transactions directly on the device (offline, from contract ABIs) so you see human-readable details like “Swap 1,250 USDC for 0.45 ETH on Uniswap” instead of raw hex.
This update makes it even stronger:
- ERC-8213 implementation now displays standardized EIP-712 typed data and calldata digests right on the screen. You can independently verify the exact message or transaction you’re signing.
- Expanded protocol support in ERA Lens:
– Uniswap (Universal Router) V2, V3 & V4 swaps
– SushiSwap swaps
– Fly swap aggregator
– Aave actions: supply, borrow, repay, withdraw - New chain support inside ERA Lens: Unichain and Boba Network
- 28 new tokens added, including USDKG on Ethereum
If a transaction can’t be decoded or doesn’t match a known interface, ERA Lens blocks the signing flow and flags it for manual review. You stay in control — always.
Why This Matters
In a world where sophisticated attacks and clever phishing are constant threats, having a hardware wallet that:
- Never connects to anything,
- Shows you exactly what you’re approving in plain language,
- Lets you manage multiple isolated wallets easily,
…is more valuable than ever.
The update keeps ERA’s core promise intact while removing the last practical pain points for power users.
If you’re already an ERA owner, just update your Companion app and install the new firmware via NFC — it’s straightforward and cryptographically verified on-device.
And if you’re thinking about getting one for the first time or adding a second device for redundancy, you can get a solid 10% discount with the code FPORTAL10 at the official shop.
