    Last friday was my last day at Ledger. Extremely humbled by what we accomplished and wishing all the builders and self custody believers there the best in their journey to make the space safer.

    Thanks to @BrutalTrade for joining the fight with @_SEAL_Org tonight - more ransom funds frozen. Asking for a ransom onchain means the entire community is fighting against you - not a smart move.

    We've decided not to move forward with Smoo.th - we reconsidered our go to market strategy during our road show and couldn't figure any that would be suitable for the growth scenario we envisioned as a team. Therefore we'd rather save everybody time and money.

    Merci et je profite du micro pour signaler que nous avons pu atteindre ce status car nous sommes une boîte "en dur" (tellement qu'on a construit une usine de 4000m2 à Vierzon) - aujourd'hui les futures licornes pure player protocole blockchain se battent pour le droit au compte

    PSA there's some kind of Twitter campaign ongoing linking to an /article/ link of an official account that silently redirects to a different malicious one. Stay safe.

    Replying to @TuurDemeester and @LedgerHQ
    The partnership was just an announcement about us testing SGX. We're extremely clear about the security trade offs (see github.com/ledgerhq/bolos…) and this has absolutely no impact whatsoever on our other product lines (typically hardware wallets)

    I try not to hype things too much, but I strongly believe this will change the way we look at hardware wallet development - github.com/LedgerHQ/app-s… - huge congrats to greenknot, @salvatoshi and team, the future will be merkleized. Your move @LarryBitcoin :)

    Bah non, ils sont tous les bienvenus. La souveraineté digitale et financière devrait être un enjeu majeur pour tous les bords politiques.
