Solana glossary

A deterministic pricing function used by Pump.fun and similar launchpads where token price rises smoothly as buyers acquire tokens from the curve. Once the curve's market-cap threshold is met, the token 'graduates' and migrates to a regular AMM like Raydium.

A trading strategy where a bot automatically mirrors the on-chain trades of one or more target wallets into your own wallet, sized by a configurable rule.

A Solana validator plugin interface that streams account updates, transactions, and slot changes out of the validator in real time, used to feed external indexers and gRPC servers like Yellowstone.

A Solana transaction submission mechanism that groups multiple transactions into an atomic, priority-ordered bundle auctioned to block producers for same-slot inclusion — protecting trades from public-mempool MEV.

Solana's dominant DEX aggregator — routes swaps across every liquidity venue (Raydium, Orca, Meteora, Pump.fun, etc.) to find the best available price for a given token pair.

A Solana wallet belonging to a known trader or influencer that the public tracks — typically surfaced on aggregator sites like kolscan.io and used as a copy-trade target.

The profit searchers extract by reordering, inserting, or frontrunning transactions within a block. On Solana, MEV flows primarily through Jito's bundle auction rather than public mempool sandwiching.

Realized PnL is the profit/loss you've locked in by selling positions. Unrealized PnL is the paper profit/loss on positions you still hold — it can evaporate before you exit.

An MEV attack where a searcher frontruns your buy (pushing the price up), lets your trade execute at the inflated price, then backruns with a sell to profit from the impact. Copy trades are especially exposed.

The difference between the expected fill price of a trade and the actual fill price, driven by liquidity depth and price movement between order submission and execution.

The JSON-over-HTTP API that every Solana node exposes for reading chain state and submitting transactions. Fine for basic queries, limiting for latency-sensitive trading vs gRPC streaming.

A high-throughput gRPC streaming protocol for Solana that pushes account updates, slot events, and transactions directly from a validator's Geyser plugin to clients.
