Wormhole is a cross-chain messaging protocol that lets assets and data move between Solana and other blockchains. Bridging does not physically move a token — the original is locked or burned on the source chain and a representation is minted on the destination, with a network of guardians attesting that the first step happened. That attestation layer is the entire trust model and the entire risk: a bridged token is worth what the bridge is worth, which is a different proposition from holding a native asset. Wormhole has also been used as infrastructure beyond asset transfers, including by oracle networks delivering price data.

Raydium is the largest automated market maker on Solana by total value locked, holding somewhere between $1.5B and $2.2B through 2026 and processing tens of billions in quarterly volume. It runs several distinct pool types rather than one: concentrated liquidity pools for deep pairs, constant-product pools for everything else including most memecoins, and LaunchLab, its own bonding-curve launch venue added in 2025. For a memecoin trader the practical relevance is that a large share of Solana pairs live in Raydium pools, and which pool type a token sits in determines how its price behaves under pressure.

Pyth Network is an oracle that brings real-world prices onto Solana and other blockchains, sourced directly from over 120 publishers including trading firms like Jane Street, Cumberland and Wintermute alongside venues such as CBOE. It uses a pull model: prices are aggregated continuously on Pythnet, its own appchain, and an application requests the latest update on-chain at the moment it needs one, rather than a feed being pushed constantly whether anyone reads it. That design is why oracle costs scale with usage instead of with time, and it is the main structural difference from earlier oracle networks.

Metaplex is the protocol that supplies Solana’s metadata layer — the programs that attach a name, symbol, image and creator information to a token or NFT. This matters far beyond NFTs, because the SPL Token Program itself stores none of that: a mint records supply, decimals and authorities, and nothing else. Every memecoin ticker and logo you have ever seen in a wallet comes from a Metaplex metadata account sitting alongside the mint. That separation is also why token names can be changed after launch, and why the ticker is not an identifier.

Helius is a Solana infrastructure provider whose main product is RPC access — the endpoints that wallets, DEX interfaces and bots use to read chain state and submit transactions. An RPC node is not a validator: it does not vote or produce blocks, it maintains a copy of the chain and answers queries about it. Every action you take in a wallet passes through one, and the quality of that endpoint determines whether your transaction reaches a leader in time or quietly dies in a queue. Most traders never think about RPC until a launch, when suddenly it is the only thing that matters.

Token-2022 is a separate Solana token program that keeps the original SPL interface intact while adding optional features called token extensions — transfer fees, confidential balances, freeze-by-default states, hooks that run custom code on every transfer, and a permanent delegate that can move tokens without the holder’s signature. It does not replace the original SPL Token Program; both run side by side at different program addresses, and a mint belongs to exactly one of them forever. For traders the practical consequence is blunt: two tokens that look identical in a wallet can behave completely differently on transfer.
