OpenSea has two tasks that can be completed with skill One is to purchase an NFT worth $5 through the Abstract chain, and the other is to exchange at least $5 worth of tokens through the SOL chain, which can be done simultaneously First, transfer an appropriate amount of tokens to the Abstract chain through OpenSea's cross chain bridge, purchase NFTs, and then transfer ETH tokens larger than 5U from the Abstract chain to SOL (at a very low cost). This way, the task of the SOL chain can be completed directly without the need for further redemption https://((opensea.io))/token/abstract/0x0000000000000000000000000000000000000000? direction=to&counterpart={%22chain%22:%22ethereum%22,%22contractAddress%22:%220x0000000000000000000000000000000000000000%22} Cross chain tokens to SOL chain https://((opensea.io))/token/abstract/0x0000000000000000000000000000000000000000? direction=to&counterpart={%22chain%22:%22solana%22,%22contractAddress%22:%2211111111111111111111111111111111%22}
