On-Chain Glossary

A plain-English reference for the terms you will see when tracking wallets on Solana. Bookmark this page whenever a concept needs a quick definition.

Smart Money

Capital controlled by experienced, well-informed participants. On-chain, it refers to wallets whose trading is consistently profitable and risk-managed.

Wallet Address

A public identifier on a blockchain that can send and receive tokens. On Solana it is a base58 string; all of its activity is visible on block explorers.

On-Chain Data

Information recorded directly on the blockchain — transfers, swaps, and balances — that anyone can read and verify.

Win Rate

The percentage of a wallet's tracked trades that were profitable over a measured window. A high win rate suggests discipline, not guaranteed profits.

PnL (Profit and Loss)

The realized and unrealized gains or losses of a wallet's positions, usually expressed in a base currency or SOL.

ROI (Return on Investment)

The percentage gain or loss relative to the amount invested. Often annualized or measured over specific windows like 7 or 30 days.

Drawdown

The decline from a portfolio's peak value to its trough. Lower drawdowns indicate better risk management.

Liquidity Pool

A pool of tokens locked in a smart contract that enables decentralized trading. Solana pools on platforms like Raydium are where most swaps happen.

DEX (Decentralized Exchange)

A protocol that lets users trade tokens directly from their wallets without a centralized intermediary.

Meme Coin

A cryptocurrency driven primarily by community and culture rather than fundamentals. Highly volatile and high-risk.

Micro-Cap Token

A token with a small market capitalization. Micro-caps can move dramatically on low volume, amplifying both upside and risk.

Copy Trading

Automatically replicating another wallet's trades. Convenient, but it transfers that wallet's risks — and losses — directly to you.

MEV (Maximal Extractable Value)

Value that can be extracted by reordering, including, or excluding transactions in a block, such as front-running swaps.

Slippage

The difference between the expected price of a trade and the price at which it executes, common in low-liquidity tokens.

Gas / Transaction Fee

A small fee paid to process a transaction on the network. Solana fees are typically very low compared to other chains.

Block Explorer

A tool (such as Solscan) for viewing on-chain addresses, transactions, and token activity. The source of truth for verification.

Token Swap

Exchanging one token for another, usually via a DEX liquidity pool rather than an order book.

Whale

An address holding a large amount of a token or capital. Whales can move markets when they trade.
