Hardwares are internally exploited. $200 tech gets compromised. Here's how Coldstar makes that impossible:

I fucked up with $COLD. I’m not going to hide from it or make excuses. Here’s what happened.

For transparency: we sold $COLD after feeling we weren’t receiving the support we expected from EasyA. Our tokens were locked 2 months ago. We reassessed our position and sold. The subsequent pump was organic market activity and wasn’t the reason for our sale.

Think about it Privately buy hardware with cash Privately flash it into a cold signer Privately store Solana Privately send Solana Privately trade Solana A true complete private workflow Who else is doing this?

Update on our iOS app: WE ARE VERY VERY CLOSE! iOS works a little differently to Android to when interacting with USB drives We have architected a solution but executing the plan has been quite difficult As this is an open-source project, are there any devs who can help us?

The right question for agentic finance isn't "can the agent be trusted." It's "what can it do if it can't." Design for the compromised case, because that's the only case that matters.

Cold storage isn't a product category. It's a property: can this key be reached from the internet, yes or no? Everything else is packaging.

An agent holding your private key isn't an assistant. It's an employee you never background-checked and can't fire mid-transaction.
