Burned vs locked liquidity on Solana: what buyers verify

"LP burned" and "LP locked" both claim the creator cannot pull the pool. One is permanent and needs no trust, the other expires and depends on a contract. Here is what each means on-chain and how to verify a burn yourself.

How to Airdrop Tokens on Solana: Snapshot, List and Costs

A Solana airdrop is a snapshot, a cleaned recipient list and a series of batched transfers. The main cost is not fees but token account rent, about 0.00204 SOL for every recipient who has never held the token.

Launching a token on Solana is eight decisions, not one button. This checklist covers supply, metadata, what it really costs, which authorities to revoke, how liquidity works and how to verify the result like a buyer would.

How to spot a Solana rug pull: a trader's pre-buy checklist

Most Solana rug pulls use one of a handful of on-chain powers, and every one of them is publicly readable before you buy. This is the checklist I run on a new token, where to look for each item, and what it cannot tell you.

How Unstaking SOL Works: Epochs, Cooldown and Lost Stake

Unstaking SOL is two steps: deactivate, then withdraw once the current epoch ends. This guide explains stake account states, why the wait is up to about two days, and how stake accounts get forgotten without being lost.

Mint authority vs freeze authority on Solana, explained

Every Solana token has two optional keys stored on its mint account. One can print supply, the other can stop you selling. Here is what each does, when keeping them is legitimate, and how to check any token yourself in a minute.

Fees

Solana Transaction Fees Explained: Base, Priority and Rent

A Solana transaction has a tiny fixed base fee, an optional priority fee, and sometimes a rent deposit that is not a fee at all. Here is how each one is calculated and what common actions cost in SOL.

Solana Wallet Security Checklist: Drainers and Delegates

Most Solana wallets are drained by one signed transaction or one leaked seed phrase, not by old approvals. This checklist ranks the habits that prevent it and explains what to do in the first minutes after a compromise.

Token-2022 explained for traders: extensions that matter

Token-2022 lets a Solana token carry optional extensions, and a few of them give the issuer powers the classic token program never allowed. This is what each extension does, which ones should stop a trade, and how to check a mint.

What is wrapped SOL (wSOL)? Why it exists and how to unwrap

Wrapped SOL is ordinary SOL sitting inside an SPL token account, backed one for one with no issuer. It exists because DeFi programs only handle tokens, and leftover wSOL converts back to SOL by closing that account.

Spam NFTs on Solana: what to do with them (hide or burn?)

A spam NFT in your Solana wallet cannot hurt you by sitting there; the claim site it advertises can. Hide compressed spam, burn regular Metaplex NFTs to get their rent back, and never open the link.

Why Solana Transactions Fail: Common Errors and Fixes

A Solana transaction either never lands or lands and fails, and the two cost different amounts. This guide covers the real failure modes, what each error message means, and how to read a failed transaction's logs.

Is it safe to close Solana token accounts? Risks explained

Closing an empty Solana token account is about as low-risk as on-chain actions get, and the account can be recreated at the same address later. The permanent step is burning a balance. Here is where the line sits.

Rent Basics

How much SOL can you recover by closing token accounts?

Every empty SPL token account holds 0.00203928 SOL, so the estimate is simple multiplication: accounts times deposit, minus fees. Here are the numbers by account type, a table of totals, and what reduces the figure.

Rent Basics

Solana's hidden rent cost: where token accounts come from

The 0.002 SOL that disappears when you buy a new token is not a network fee. It is a deposit on a new token account, and swaps, airdrops, NFT mints and memecoin trading each leave those accounts behind in a different way.

Rent Basics

What is Solana rent? The refundable deposit on every account

Solana rent is not a recurring charge. It is a one-time deposit, sized by how many bytes an account stores, that keeps the account on chain and comes back in full when the account is closed.
