Hi Product Hunt! I'm Tom, and I've been building crypto wallets since 2013 (BitBill was one of the earliest Bitcoin wallet teams). Ownbit started in 2017 with one idea: professional-grade custody shouldn't require buying hardware or trusting a custodian. So we built: - A two-phone cold wallet — one offline phone signs, one online phone watches and broadcasts. Air-gapped, no extra device to buy. - Full multisig on BTC, ETH, TRON, Solana and most major chains, using open-source contracts and standard scripts, so recovery never depends on our servers. - Crypto inheritance — probably the hardest unsolved problem in self-custody, built in natively. No KYC, no data collection, 9 years without a security incident. Would love your feedback — especially from anyone managing team funds or thinking about what happens to their coins in 30 years. AMA!
