Jev acts as an onchain firewall in a 2-of-2 Safe on Base
In a 2-of-2 Safe wallet, Jev serves as a guard that simulates transactions and checks contracts and past recipients before signing, blocking unlimited approvals to fresh contracts and judging within 100ms whether a transaction matches your intent.
onchain firewall using Jev by @typesafeai & @safe on @base 👇 how that works: 1. wallet is a 2-of-2 Safe: your key + jev guard 2. before signing, the guard reads the chain: simulates the tx, checks contracts (verified? how old?) and past recipients 3. hard rules catch unlimited approvals to fresh contracts, lookalike addresses etc 4. jev judges the rest in 100ms: does tx actually match what you meant to do? 5. safe → guard signs. scam → tx never exists. unsure → it asks you gives you an automatic security check on every transaction, in ~0.5s, before it's even signed
