Multichain users who didn't update their approvals as instructed yesterday have been exploited and have lost 445 wrapped ether ($1.4 million), the project tweeted on Tuesday.
- On Monday, Multichain instructed its users to remove approvals for six tokens and said otherwise their assets would be exposed to a security vulnerability. The tokens in question were WETH, PERI, OMT, WBNB, MATIC and AVAX.
- Decentralized finance security firm Dedaub first found the flaw, which Multichain said it had fixed.
- Later on Tuesday, crypto security firm PeckShield revealed the wallet address where the stolen funds had been deposited. The address holds 455 ether as of the time of writing.
- Because the users have to be the ones to remove the approvals, there isn't much Multichain can do, PeckShield told CoinDesk in a Twitter message.
- Multichain, formerly Anyswap, is a cross-chain bridge which raised $60 million in December in a seed funding round that was led by Binance Labs.

What to know:
Pudgy Penguins is emerging as one of the strongest NFT-native brands of this cycle, shifting from speculative “digital luxury goods” into a multi-vertical consumer IP platform. Its strategy is to acquire users through mainstream channels first; toys, retail partnerships and viral media, then onboard them into Web3 through games, NFTs and the PENGU token.
The ecosystem now spans phygital products (> $13M retail sales and >1M units sold), games and experiences (Pudgy Party surpassed 500k downloads in two weeks), and a widely distributed token (airdropped to 6M+ wallets). While the market is currently pricing Pudgy at a premium relative to traditional IP peers, sustained success depends on execution across retail expansion, gaming adoption and deeper token utility.
