The account structure of Solana is very different from Ethereum. When each SPL token is recharged or traded to the Solana wallet, some SOL needs to be used to open the SPL token account for that wallet. So the more dirt dogs a wallet has on Solana, the more SOLs it will be occupied. Even if the local dogs are sold, these occupied SOLs will not be automatically released as' rent '. OKX @ Wallet has keenly identified this demand and developed a "rent recovery" feature that can be released with just one click. Both the app and PC versions are available, with the entrance located on the homepage of the wallet app - More - Solana Account Rent Recovery. It feels good to 'pick up' the money again 😎
