Ledger just released a new update for Nano X that allows social recovery of your seed phrase.
It encrypts your seed in 3 shards and sends it to different entities that can then reconstruct the seed for you post ID verification.
It's a horrendous idea, DON'T enable this feature.

There is a new phishing contract called "claimRewards" which attempts to drain wallets. The Hexagate extension (chrome.google.com/webstore/d…) detects this malicious contract and indicates this is a malicious tx and a malicious website.
Anyone can install the extension to stay safe!
Hey @JackNiewold thanks for the follow. Oops that was your twin: @JackNiiewold_ .

The @Arbitrum Foundation has just announced an official airdrop! 👏 🪂 While this was widely expected, scammers have been taking advantage of this possibility to run a variety of fake airdrop websites.
You can check your $ARB airdrop eligibility at arbitrum.foundation. The site has a simple wallet connection option, after which you can check your eligibility. If you see a prompt that asks for keys, token approval, or anything besides viewing your wallet address, do not approve/sign!
A Visual Guide to @0x_PolygonZK
It’s a Rollup — It’s ZK — It’s EVM Compatible — Is it Magic?
One-page graphical view of Polygon’s zkEVM architecture: an attempt to understand this ambitious and complex feat of engineering.
First @silvergatebank at #128 by assets, now @SVB_Financial #16 (!) largest US bank by assets, per federal reserve.

Wonder what kind of phishing we will see playing off of SVB the next few weeks and months.
Spending some time looking at @0xPolygonZK.
I mean, is this perpetual motion?
- Scales Ethereum with low cost per transactions
- Leverages Eth security as a rollup,
But wait there's more:
- Somehow manages EVM support in ZK proofs
Weird ERC20s - Thanks to @deanpierce for a heads up on this handy list of non-standard token implementations:

❓How many requests do you need to examine transaction execution down to the last detail? One – tenderly_traceTransaction.
You can run our custom JSON-RPC via Tenderly Web3 Gateway and replay a tx after its execution. 🧵

The company had to make yet another disclosure to detail a second incident that allowed attackers to rampage through the company's cloud storage and exfiltrate sensitive data. wired.trib.al/PsDA9GY
