crypto finally built airplane mode for your keys.

@faradaysigner joins the IKA Space to talk air-gapped signing, QR-only wallets, and why your private keys should never touch the internet.

no wifi. no bluetooth. no nfc. you just scan.

set reminder ↓

[DEFICATALYST @CatalystSon]

the biggest threat to crypto isn't the blockchain, it's the moment you click "Approve."

in February 2025, the crypto industry witnessed one of its biggest security disasters when approximately $1.5 billion was stolen from Bybit.

what makes the incident particularly alarming is that the attackers didn't break Bitcoin's cryptography, crack Ethereum's security or somehow defeat blockchain technology. Instead, they exploited the transaction approval process itself, manipulating what signers saw and ultimately causing a legitimate transaction to authorize something entirely different.

and the scary part is how most crypto users looked at the incident and thought:
“That could never happen to me.”

but that’s exactly the wrong conclusion because the biggest threat to your wallet isn’t always someone stealing your private keys.
sometimes, it’s you signing the wrong transaction.

@faradaysigner was built to solve exactly that by keeping private keys completely offline and transforming complex transactions into clear, human-readable instructions before signing.

Wondering how an offline device signs online transactions?

QR codes. No Bluetooth. No WiFi. No NFC.

Build a tx in any Solana app. The extension shows a QR. Scan it with a Faraday cage!

Review on the device screen. Approve. Get a signed QR. Scan it back.

@d3h3d_ @faradaysigner It’s always such a blast chatting with people who share the same mindset! Let's keep in touch and stay on each other's radar. Some great things will turn up.

Our @colosseum submission is in

We built an air-gapped Solana signer on a Pi Zero.

No WiFi, no Bluetooth, no network. Keys never touch the internet. QR in, QR out!

These have been incredible weeks of building!
