Solana used to be an extremely active ecosystem for random memecoins, tokens, and NFTs, but now that craze seems to have died down.
I don't trust memecoins and random tokens, which means I generally get rid of airdrops the second they reach my wallet.
But, recently, I was doing some 'housekeeping' and found out you can actually 'reclaim' SOL.
First, I found out you can simply close the account and reclaim SOL that had been used to 'rent' that token account and keep it open.
Then, today, I found something called Sol-Incinerator.
It's a thing.
Why is there SOL hidden in your wallet?
Every time you interact with a new token, mint an NFT, receive an NFT, receive an airdrop and so on, Solana creates new storage account on the blockchain.
In order to do that, it requires a small storage deposit of real SOL - known as 'rent-exemption' - to keep that data live on-chain (typically around 0.002 SOL per token account, and even more for NFTs with complex metadata).
When you sell, swap, or send away a token, that token balance hits zero but the empty account remains open, and your SOL storage deposit stays locked inside it indefinitely until the account is explicitly closed.
Sol-Incinerator is an non-custodial Solana dApp designed to sweep everything away and recover locked and unused funds.
It detects zero-balance token accounts and also destroys worthless spam tokens, rugged NFTs, dead memecoins, and so on.
It's compatible with all main Solana wallets and it works a treat.
