Did you know that for every junk airdrop you receive in your Solana wallet, you will be charged 0.002 SOL?

That's right, this is part of Solana's account rent mechanism. Some of you might ask, "I wasn't charged rent when I created my Solana address."

Okay, before understanding the Solana account mechanism, let's differentiate between the concepts of address and account.

In the Solana architecture, an account ≠ an address. Solana addresses are created for free, can receive assets, sign transactions, and do not occupy on-chain storage.

This point is crucial: they do not occupy on-chain storage.

So when is "rent" charged? It is charged when on-chain storage is occupied.

How is on-chain storage occupied? Suppose someone transfers USDC to you; the Solana system needs to create a "USDC Token" account, which requires deducting 0.002 from your SOL balance as rent. Once the account is created, the USDC arrives.

Another common situation is passively receiving junk token airdrops, where the system automatically creates a junk token account for you, deducting 0.002 SOL as rent. Your wallet ends up with junk airdrops, and your SOL decreases.

So, the relationship between address and account is similar to having multiple accounts under your name to receive different tokens. Each time an account is created, 0.002 SOL rent is required. However, in many cases, account creation is passive.

The following image from Solscan shows the situation of the MEME token SBAE, where the SOL Balance of 0.002039 is the rent.

On the USDC page, although the SOL Balance is not displayed, the Owner Program is the Token Program, which means rent still needs to be paid.

Why is there "rent"?

It is actually to prevent state explosion, similar to a DDOS attack, and to stop someone from maliciously spamming tokens on-chain. The real situation is to reduce the airdrop costs for legitimate projects, making it so that those who benefit pay the fees. This has, however, been exploited by many junk MEME creators to generate false holding address data.

Is there a chance to recover the rent?

Junk.Fun is precisely the solution to this problem. Junk.Fun is a junk token recycling platform in the Solana ecosystem. After recycling worthless MEME or NFT tokens, users will receive Credits. Credits can be directly withdrawn as SOL, or users can exchange them for Junk.Fun treasure chests to win $SOL tokens, physical prizes (like an iPhone), NFTs, and other rewards in future airdrops.

During the first month of activities, Junk.Fun will distribute at least $50,000 in prizes.

Each time a user recycles a token, a fixed percentage of the transaction fee will go into a growing reward pool.

Early users and partners will also receive exclusive referral links. The first 48 hours will adopt an invitation-only access mechanism.

In fact, the existing recycling tools in Solana have processed over 400,000 SOL, worth over $900,000, with more than 100,000 addresses. The market demand is huge and real.

The core modules of Junk.Fun include:

1) Bulk destruction and rent recovery

Select all junk tokens/NFTs with one click; bulk destroy and close accounts; rent is automatically deposited into the Junk.Fun account.

2) Treasure chest lottery

Purchase treasure chests with Junk.Fun balance;

46% chance of winning lottery rewards;

Opening a legendary treasure can yield up to 60% of the total prize pool.

3) Friend referral system

When friends open treasure chests, the referrer earns a commission.

In the subsequent phases, Junk.Fun's gameplay will become more gamified and fun. Various PVP game modes will be added, allowing players to win treasure chests and subsequently win SOL through competition.

This scenario not only leads to PVP battles but can also evolve into tournaments, social games, team competitions, and more. From "one-time use" to "continuous participation," from "recycling tool" to "gaming platform," from "cleaning wallets" to "entertainment ecosystem."
