Turn any USB stick you already own into a hardware wallet with @coldstar_sol:
keys decrypted only in memory, offline QR signing, open source, one-line install, 1% fee capped at $10.
Three-quarters of a million dollars signed in its first ten weeks, according to the team. W!

Next picks from the @colosseum Crypto World’s Fair. This time: Infrastructure, Security & Privacy.🛡️Here is my personal pick 👇
Security:
@coldstar_sol - turns any USB drive into an offline signer for Solana. Your keys exist for a split second, then they are gone
@hackhackai - AI security audits built by Solana auditors and checked with real exploit tests
@ProofOfExploit - smart contract audits for early Solana teams that are affordable and can be trusted
@iris_intel_app - shows who is really behind a wallet or a token, and follows stolen money across chains
Stakeward by @alexandr_zhibul - keeps your staked SOL safe, even if someone steals your wallet key
Privacy:
@VisionSwapSol - a private pool, live on Solana mainnet. Send and trade with no link back to you
@TiraiProtocol - private, quantum-safe transfers between Solana and Ethereum for institutions

I met @devsyrem from judging some bounties on @SuperteamEarn about NFTs on @solana. Soon after he shared his vision for @buildcoldstar. I knew he was a bright young founder with talent and integrity from his work. We focus on building hardware and security for developers on @solanamobile. We met in person at @SolanaAccel in Miami in and launched @buildcoldstar. We are making even bigger plans for @buildcoldstar to provide Infrastructure for the Next Generation of @solana_devs.
