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!
