- UnlockShare a family wallet that needs two of three to move moneyA Safe multisig requires a set number of owners to approve any transaction, so no single lost phone or bad decision drains it.
- SolutionHow to avoid crypto wallet drainer scamsYou can see in plain words what any site will make you sign before you sign it: scan the request with Recon. For savings, add Second Signature as an AI cosigner on a Safe, so money only moves when it agrees. Check and revoke old approvals with Revoke.cash.
- SolutionRefugee with no papers: prove who you are and your skillsYou can start a record today that no border can take: an ID key you make yourself in a browser, references former colleagues sign for you onchain, and certificate copies stored permanently. UNHCR has already paid displaced people in USDC to phone wallets. This record is strong supporting evidence; legal status still comes from governments and UNHCR.
- SolutionPool village money for a well without anyone stealing itYour village can hold a fund that no single person can spend, and that anyone can check on a phone. A multisig wallet needs, say, three of five elders to sign each payment, and every gift and payout is public. Relatives abroad send straight in, and the driller is paid stage by stage. Skip this if you need protection from a whole group colluding: a multisig stops one thief, not many.
