Your wallet gets one more chance before a suspicious withdrawal becomes irreversible.

Is the WorldIDVerifier 4.0 already deployed to mainnet? @worldnetwork @worldbuildlabs
Just attended my first @cognition meetup in Florianópolis @ipecity 🇧🇷
Mind blown learning about Devin and @windsurf 🤯
Last month, I received a newsletter from @maggielove_ that said:
"When anyone wins the thing you want, that's not the universe rubbing it in. That's the universe saying, there it is again. It's real. It's still available."
That line stayed with me.
A week later, I went to a crypto event in Brazil and met a girl who had just won 1st place in a hackathon.
After talking to her, I remembered Maggie's Newsletter and thought to myself, "This is now proof, right in my face, that what I want to achieve is possible."
Update on LockFi 🔐
LockFi is a smart vault that delays suspicious withdrawals to give users time to react before funds are lost.
New feature: users can now immediately withdraw to a pre-configured safe address during suspicious activity.
Not just delay.
Now, an escape route.
I won 1st PLACE at the @monad Hackathon with LockFi 🏆🥹
LockFi is a safe lock to keep your assets, it detects suspicious withdrawals and delay them, giving users time to cancel before funds are lost
That’s just the first MVP. Excited to keep shaping it!

This week at MERGE in São Paulo I realized talking about crypto in Portuguese is more difficult, I keep looking for words because everything I learned in web3 was in English 😭
