Been playing with the @Ledger firmware.
@JupiterExchange swaps now clear-sign on my Nano S with token tickers, amounts, slippage and supporting instructions.

This is huge.
Solana has the same problem and it's brutal. Your Ledger shows a base58 program ID and "Blind signing ahead, accept risk." You sign because what else are you supposed to do.
That's what we're fixing with Lucid.

0/ Clear signing is now live.
An open standard to end blind signing, making human-readable transactions default.
This effort brings a major UX and Security upgrade to transaction signing on Ethereum.

Lucid won the Public Goods track by solving blind signing on Solana.
Thanks everyone for a great time in Belgrade.

Another amazing Demo Day in Belgrade is behind us. This one proved that @Solana took over the Balkan region.
-- 30 teams pitched (many new cracked ideas)
-- 100 guests IRL 2.3k views on a 5-hour X live
-- more late nights than ever, but we truly enjoyed all of them

1/ Multisig signers on Solana approve transactions their hardware wallet can't read.
The Ledger throws a "blind signing" warning. Trust falls back to the multisig UI.
When that UI is compromised, the hardware wallet you bought as your trust anchor offers zero protection.

4/ The on-chain program reconstructs the exact message from the intent definition proposal parameters, then verifies the ed25519 signature against it.
If anything is tampered between proposal and signing, the signature won't match and the program rejects it.

5/ No blind signing. No UI as your last line of defense. You only need to trust the hardware wallet.
Built for @solana @colosseum Frontier:
· On-chain program (Pinocchio)
· Dashboard
· CLI SDK
Soon live on Devnet: uselucid.xyz
