Announcing the debut of a new service! Now you can contact me and my friend @rata0x for legal services and advice. We've known my dear friend t.me/rata0x for 5 years, and we've helped a lot of individuals in the most desperate situations! So, if you need to: 1. Resolve the issue of unauthorized blocking of funds on the exchange. 2. You have had a huge sum of money stolen from you and must immediately block it on exchanges and return it as soon as possible. 3. You or your project require legal assistance and advice. Contact t.me/rata0x ! When I refer him, I use my name because I've worked with him for a long time and know him well.

Three Good Multisig Operations Tips! 1) You can create multisig with Safe, and sign transactions off-chain and send them using any other wallet that doesn't control multisig at all. So, you could use Safe contract alternatively to any ERC2771 smart contracts (like Openzeppelin Defender is). 2) How to choose a better number of signers? Pick a M-of-N multisig where M is less than N, such as 2-of-3. Give yourself some leeway, a 2-of-2 requires all your backups to work perfectly. 3) Implement Web3 Front-end monitoring, use a tool by @koda (link below)! P.S. That’s an awesome app: pilot.gnosisguild.org

A victim lost $510,294 due to copying the wrong address from transaction history! Victim: 0x0d534863a71d5e68d5c919a4c2ef47c3a7a792c0 Fake address: 0x4049Ebf479Fa49924e120490d119f0827cAa9aeC Legitimate address: 0x40491fe2bA81621475c894Ebe8bcad56C7da9aec How transaction history poisoning works: 1. Scammer sends fake/dust transfer with similar address; 2. Their fake address appears in your history; 3. You copy address from history thinking it's legitimate; 4. Funds get sent to scammer instead. How to stay protected: 1. Always double-check the addresses you're sending funds to; 2. Never copy addresses from transaction histories; 3. Use a wallet that supports whitelisting or bookmarks.

GM folks, please please please never ever download any PDF or install any software during a call with VC. Two CEO’s of a Defi Protocols got hacked in this way, lucky they engaged with me and rata0x and we managed to recover nearly 1m$ stolen assets. However, if they wouldn’t install the app during the meeting, they wouldn’t lose over 5m$… Since I stated to assist and engage with more hacking and stolen assets, I will share my first hand experience for better on-chain security of you. Rata0x and I are here to help.. Our mission has recovered over $100M so far.
