@MARcryptoTIN PulseChain-branded Keystones are currently in the manufacturing phase, and the expected delivery is in 5-6 weeks.

[Keystone Hardware Wallet @KeystoneWallet]

@13jujusam13 @0xHoldX @LibertySwapFi Branded devices are made on-demand. So, they usually take this time.

[Keystone Hardware Wallet @KeystoneWallet]

@w3gio Not at all.
We haven't seen an unusual offer like this before.
So, we genuinely want to know the possible reason behind this decision 💙

@prezthedegen It's a win-win!

🚨 Humanity Protocol lost $31M yesterday.
The token dropped 90% in hours.

Behind that number are real people who trusted the project with their money.

What happened:
A team member's laptop was compromised. Private keys leaked. The attacker took over the multi-sig, drained the treasury, minted new tokens, and dumped them.

Nobody woke up that morning planning to lose everything.

But some habits made it inevitable:
→ Signing keys living on internet-connected laptops
→ One person holding multiple multi-sig keys
→ No cold storage between the team and the treasury

This pattern keeps repeating, and it's always token holders who absorb the loss.

The hard part isn't the cost.

A hardware wallet costs $50–100 and keeps private keys completely offline. The hard part is treating security as a responsibility before something goes wrong.

For project teams and individual holders alike — it's worth taking seriously.

Stay cold. Stay air-gapped.
