A new exploit on the old Opensea contract is being used to steal your NFTs.

⚠ Signing this seemingly innocent transaction could drain your wallet.

Here's a simple breakdown. ⬇⬇
This new exploit dupes the user into signing a transaction, granting the attacker control over the user's proxy contract.

#NFTs #opeansea #artwork
It can steal any NFT that users listed on Opensea before May 2022 (i.e. before Seaport upgrades), primarily through the Wyvern protocol, which grants proxy contracts the ability to withdraw user NFTs.
How to keep yourself safe?

🔅 Check your transaction and read what it's doing carefully.

🔅 Second, you can go to @RevokeCash and revoke "Opensea (old)" permissions.

🔅 The third option is to follow @QuillAudits on Twitter & Telegram to stay updated.

Exploiters minted over 1 Billion in $GALA tokens on BSC & fears caused a 20% drop in GALA.

The problem is caused by a misconfiguration of the @pNetworkDeFi bridge.

#GALA #galatoken #breach

🧵👇 $1B Crypto Hack Fears Spur ...
➡️ Hackers immediately sent the freshly minted GALA to #PancakeSwap.

➡️ The attacker dumped a total of 10.72 billion $GALA and earned a total of 12,977 billion $BNB ($4.4 million) by draining the PancakeSwap pool to zero.

#news #Hack
@pNetworkDeFi stated that a new pGALA token will be created to replace the old compromised one and will be airdropped to those who had pGALA before the pool was drained in the coming days.

⚠️⚠️

On July 28, Solana-based DeFi protocol @nirvana_fi lost $3.5M to a Flash Loan attack.

After the attack, Nirvana’s native token $ANA lost 85% of its value.

Its #stablecoin $NIRV lost 90% of its US dollar value in the process

👇👇
This hack was similar to previous flash loan attacks, such as one on @Crema_Finance ($6M loss).

#Nirvana | #Crypto
In the current scenario,

The hacker used flash loans to manipulate the $ANA price from $8 to $24.

The hackers then siphoned off 3,490,563.69 $USDT after claiming $USDC and $USDT at this inflated price.

Decoding #Ethereum Rollups: zk, zkVM, zkEVM

Last week, a trio of @Scroll_ZKP, @0xPolygon, and @zksync announcements had something in common:

Each company implied it would be the “first” to bring a zkEVM to market.

🔽MEGA...🧵👇
TL; DR

➚➚There are several applications for zero-knowledge proof in blockchain scaling and privacy since it can ensure computational integrity, accuracy, and privacy.

➚➚Both zk-SNARK and zk-STARK have advantages, but their combination offers more possibilities.

#ETH
➚➚ZkVM provides zero-knowledge proofs for applications, and it can be divided into the mainstream, #EVM, and newly-built instruction sets.

➚➚Equivalence, specification-level compatibility, and EVM compatibility are all types of EVM compatibility.
