Quick reference for the Solana and J Tools terms used across the docs.

Solana basics

The units, fees, and mechanics that every transaction depends on.

Term	What it means
SOL	The native currency of the Solana network. You pay network fees in it, and most pools on J Tools pair tokens against it.
Lamport	The smallest unit of SOL. 1 SOL = 1,000,000,000 lamports. Network fees, rent, and tips are all counted in lamports.
Mainnet	The live Solana network where real value moves. The production tools on J Tools run on mainnet, so most actions there sign a real transaction. The read-only analysis tools read the same mainnet state and sign nothing.
Devnet	Solana’s public test network. It runs the same programs as mainnet, but its SOL carries no value and cannot cross over to mainnet. The free Devnet Faucet hands out up to 25 SOL a day for testing, with no wallet connection and no signature. The other tools stay on mainnet only, so devnet is where you rehearse a flow before spending real SOL.
RPC	The connection your wallet and tools use to read chain state and send transactions to the network. J Tools routes this through its own providers with automatic failover.
Transaction signature (txid)	The unique id of a confirmed transaction. Paste it into a block explorer to see exactly what happened on-chain.
Compute units	The work budget a transaction is allowed to use. The priority fee is priced per compute unit, so a heavier transaction costs more to push through congestion.
Simulation (dry-run)	A test pass that runs a transaction against current chain state without sending it. It catches errors before you spend any fee. Most tools run it automatically before sending, and Multi Swap also offers a Simulate button.
Rent	The minimum lamports a Solana account must hold to stay alive on-chain (the rent-exempt minimum). Closing an empty token account reclaims this rent, which is what the Close Account tool does (it keeps a 5% cut of the rent it returns).
Network fee (gas)	What Solana charges to process a transaction. It comes out of your wallet but is never counted as platform revenue.
Platform fee	What J Tools charges for using a tool, paid to the platform wallet. This is the line the affiliate program shares from. See the in-app fee summary or the Fee schedule.
Priority fee	Extra micro-lamports per compute unit, paid to push a transaction ahead of others during congestion. J Tools can estimate this automatically.
Blockhash	A recent block reference that a transaction includes to prove it is fresh. It stays valid for a short window (around 150 slots) before it expires, and an expired one just means you sign and submit again.
Confirmation	How far a transaction has settled: `processed`, then `confirmed`, then `finalized`. Most tools wait for confirmation before they report the action as done.
Slippage	The gap between the price you expect on a swap and the price you actually get. A slippage setting caps how much movement you will accept before the trade fails.

Tokens and authorities

#tokens-and-authorities

What a token is, and the keys that control it.

Term	What it means
SPL token	A standard fungible token on Solana, built on the Solana Program Library. The Token Creator mints these.
Token-2022	Solana’s newer token program. It supports extensions like a transfer fee (token tax) and interest-bearing balances. Which extensions a given tool exposes can vary. A transfer fee does not reach the creator on its own: it sits withheld in each holder’s token account until the withdraw authority sweeps it, which is what Token-2022 Tax Collector does. Some LP mints are Token-2022, which simpler scanners can misread.
Metadata	A token’s name, symbol, and image. It lives in a separate account that the update authority can edit until the token is made immutable.
Decimals	How many fractional places a token splits into. A token with 6 decimals can be held down to 0.000001, and the Token Creator sets this at mint time.
Supply	The total number of tokens in existence. New supply can only appear while a mint authority still exists, so revoking it caps the supply for good.
Mint address vs token account	The mint address is the token’s permanent on-chain id, one per token. A token account is where a single wallet holds its balance of that mint, so one mint has many token accounts.
Holder	A wallet that owns a balance of a given token.
Mint authority	The key allowed to create new supply of a token. Revoking it with Revoke Mint fixes the supply for good.
Freeze authority	The key allowed to freeze and unfreeze holder accounts. Revoke Freeze removes it so balances stay free to move.
Update authority	The key allowed to edit a token’s metadata (name, symbol, image). Make Immutable removes it, along with the other two, so nothing can change.
Immutable	A token with no authorities left to change it. Supply is fixed, no account can be frozen, and the metadata is locked. Buyers look for this.
Vanity address	A mint or wallet address with a custom prefix or suffix that you generate on purpose, for example one ending in your ticker.
WSOL (wrapped SOL)	SOL held inside an SPL token account so it can trade in pools. The free WSOL Wrapper wraps and unwraps SOL into WSOL.
ATA (associated token account)	The standard token account a wallet holds for a given mint. Empty ones can be closed to reclaim their rent.
Snapshot	A captured list of who holds a token at a point in time, used for airdrops and reward distributions.

Trading, liquidity, and routing

#trading-liquidity-and-routing

The pieces that make swaps and pools work.

Term	What it means
DEX	A decentralized exchange where tokens trade on-chain instead of through a company. J Tools works with Raydium (V4, CPMM, and CLMM), Meteora (DLMM), Orca (Whirlpool and Splash Pool), and PumpSwap. Pump.fun is a bonding-curve launchpad, not a pool DEX, so it sits apart from this list.
AMM	An automated market maker. Instead of an order book, a pool of two tokens sets the price by formula as people trade against it.
LP (liquidity pool)	The paired reserve of two tokens that an AMM trades against. Adding liquidity to one lets others buy and sell your token. See Create LP.
CLMM	Concentrated-liquidity market maker. A pool type (Raydium’s, for example) where liquidity sits inside a chosen price range instead of spreading evenly across all prices.
Bonding curve	The fixed-formula price curve a new token trades on before it graduates to a real DEX pool. Price moves along the curve as people buy and sell. Pump.fun is a bonding-curve launchpad, so its tokens start here.
PumpSwap	The DEX where Pump.fun tokens land after they graduate off the bonding curve. Some of its LP mints are Token-2022.
Pool fee tier	The cut a pool charges on each swap, set when the pool is created. A higher tier earns liquidity providers more per trade but can make the pool less attractive to traders. On concentrated pools the fees wait on your position until you collect them with LP Fee Claim; on standard pools they stay in the pool and come back when you remove liquidity.
Creator fee	A share of trading fees that a launchpad pays the wallet that launched a token. Pump.fun, PumpSwap and Raydium LaunchLab hold it in a creator vault that does not show in the wallet balance. Creator Fee Claim moves it to your wallet, and Claim Center lists it next to your LP fees, Token-2022 tax and reclaimable rent.
Price range (concentrated liquidity)	On a CLMM pool, the band of prices your liquidity actually works in. Set it tight to earn more fees per dollar, or wide to keep earning as the price drifts.
Graduate / migrate (Pump.fun)	The moment a Pump.fun token sells enough on its bonding curve to move onto a real DEX pool. After it graduates, it trades on PumpSwap instead of the curve.
Relay transfer	A privacy hop that routes funds through intermediate wallets to break the on-chain trail. Relay Transfer routes one source to one destination through relay wallets; Multi To Multi Relay does the same for many source and destination pairs.

Wallets and analysis

#wallets-and-analysis

How the wallet tools read a list of addresses and work out what is connected to what.

Term	What it means
Cluster	Two or more wallets that on-chain history ties together. Wallet Scope groups a pasted wallet list on one fact only, the address that sent each wallet its first SOL, and it leaves known exchange and bridge hot wallets out of those groups since thousands of unrelated people withdraw from the same address. J Map colors the groups on a token’s holder map from actual transfers instead: one wallet funded the other, or tokens or other assets moved between them. A cluster marks where the question starts, never a verdict on its own.
Funder (first funder)	The address that sent a wallet its first SOL. It is the single on-chain fact clusters are built from, so wallets that share a first funder land in the same group in Wallet Scope. Every funder address links to Solscan, so you can check the transaction yourself.
Fresh wallet	An address first seen on-chain within the last 30 days. Wallet Scope tags these and gives them their own filter chip. A block of wallets that all appeared in the same week is worth reading as one entity until something proves otherwise.
PnL (profit and loss)	What a wallet has made or lost on its trades. Realized PnL counts positions already closed; unrealized PnL is the paper gain or loss on what the wallet still holds. The 30-day figures in Wallet Scope deep analysis are passed through from a third-party analytics provider rather than computed by J Tools, so read them as a fast signal and not as accounting.

Bundles and reliability

#bundles-and-reliability

How J Tools lands transactions together and stays up when a provider blinks.

Term	What it means
Bundle (Jito bundle)	A group of transactions submitted together to land in the same block. Jito executes an included bundle atomically. J Tools keeps a sent bundle in flight for a short window and re-posts it across Block Engine regions, then checks the landing on-chain so a rare partial land is caught and handled. Used by tools like Bundled Trade and Pump.fun Create & Bundle Buy.
Jito	The Jito Block Engine, the public infrastructure that accepts bundles. It keeps working even when the main RPC providers are down.
Jito tip	A lamport tip paid to land a bundle. Without a tip a bundle will not be included, so it is never free, and no tip guarantees a slot. J Tools reads the live tip level and raises a tip that sits below it, up to a cap.
Circuit breaker	A health guard that benches a failing RPC endpoint for a short cooldown so traffic fails over to a healthy provider.
Slug	A tool’s single canonical id, the same across its page URL, its config, and its fee record. It is how every part of the platform refers to one tool.
Error code	The short string that names what went wrong in an API response, for example `RATE_LIMITED`. The full list is in the Error codes reference.

J Tools terms

#j-tools-terms

A few words that are specific to how the platform is built and laid out.

Term	What it means
Fee card	The summary panel on every tool that shows the platform fee and the network fee before you confirm. Read it each time, since the two charges are separate. See the Fee schedule.
Token selector	The shared picker every tool uses when you need to choose a token. You can paste a mint address or pick from tokens your wallet already holds.
Activity Log	The strip pinned to the bottom of the app that records what each tool did, with signatures you can open in an explorer.
Wallet adapter	The bridge between J Tools and your wallet (Phantom, Solflare, and others). It is what lets the app ask your wallet to sign, while the keys stay inside the wallet.
