In the last issue of ALT, I mined nearly 16,000 pixels. Because I had something to do at the time, I sold them right after the market opened. The floor price was so high that I lost a few thousand dollars. I burst into tears. In the last issue of pixels, I also mined nearly 16,000 pixels and sold them. Half of it, half of the pattern, the current cannabis ~ I hope everyone will not miss this issue, don’t miss it! miss! Passed ~ #Launchpool

🔹Introduction to this project!
Portal (PORTAL) Portal is a cross-chain game platform that allows more players to join the world of Web3.0.
The Portal platform makes discovering and playing Web3 games seamless and easy. Gamers can finally access the largest Web3 gaming network with a smooth experience. Players will be able to play on all chains without the need to bridge/swap/purchase additional tokens to play. $PORTAL is the native token in the Portal ecosystem and has the following functions: Transaction: Users can use $PORTAL to purchase game items and other game experiences in online games. Cross-chain fee token: Users can use $PORTAL to pay cross-chain transaction fees. Staking: Users can stake through Launchpad to access tokens and NFTs. Node: Users can purchase Portal nodes to assist in the verification of the network. Network Consensus: Users can stake $PORTAL into nodes to further amplify their network verification efforts. The Portal platform consists of the following core products: Cross-chain Token: $PORTAL is a cross-chain token that utilizes LayerZero’s messaging protocol. Content Discovery Platform: A content-rich discovery platform that combines web3 games so users can discover and link to play top web3 games in one place. Gaming Wallets: Secure non-custodial wallets with Web2 authenticated access (Twitter/Discord/PSN/Twitch) for seamless account creation. Games can integrate with a simple SDK and allow their games to be easily played anywhere. Node Network: A network of validators that protects the core data of the Portal platform. Staking Access: Stake $PORTAL to receive upcoming rewards on the Portal Launchpad. Portal Launchpad: Discover and access the hottest upcoming NFTs and gaming tokens within the Portal Network. As of February 21, 2024, Portal has raised $29,000,000 through private placements and public offerings.The project sells 33% of the supply to fund the development of the platform and ecosystem. As of February 21, 2024, the total supply of PORTAL is 1,000,000,000, and the circulating supply after listing is 167,134,615 (accounting for approximately 16.71% of the total token supply). Token sale and economic model token distribution: An’an’s Launchpool accounts for 5% this time

Analysis of the just-launched PayPal stablecoin PYUSD smart contract reveals the existence of so-called “centralized attack vectors.”

Smart contract security auditor Pashov noted in a recent Twitter post that PYUSD’s contract has an “asset protection” role. It wipes your balance in two transactions: first "Freeze" and then "Wipe FrozenAddress".

The reason this is considered an attack vector is that this functionality increases the damage a potential attacker can cause if they manage to access it.

Pashov noted that PYUSD has six decimal places and uses Solidity compiler version 0.4.24. What’s more interesting is that this smart contract does not “implement EIP-712 as expected by the standard.”
