What Is Raydium? Solana's Biggest AMM and Launchpad Explained

If you have traded a Solana memecoin past its launch phase, you have almost certainly touched Raydium — even if you never opened its website. Raydium is the original heavyweight automated market maker (AMM) on Solana, the place where huge amounts of token liquidity actually live, and the destination most launchpad tokens migrate to once they outgrow their bonding curve. It also runs its own permissionless launchpad. Understanding what Raydium is, how its pools work, and one important risk it carries will make you a sharper trader. Here is the full picture for 2026.

What Raydium is and why it matters

Raydium is a decentralized exchange (DEX) built on Solana that lets anyone swap tokens, provide liquidity to earn fees, and launch new tokens. At its core it is an automated market maker: instead of matching buyers to sellers through an order book, trades execute against pooled reserves of two tokens. The price comes from the ratio between those reserves, and every trade shifts it. That pooled capital is a liquidity pool, and Raydium is one of the deepest sources of it on the entire chain.

Why does it matter to a trader? Because liquidity is where price discovery happens. When a memecoin "graduates" from a launchpad, its liquidity usually ends up in a Raydium pool. When you buy or sell that token, you are dipping into Raydium reserves — directly or, more often, through an aggregator that routes part of your order there. Raydium has been a foundational piece of Solana DeFi for years, and it remains one of the largest venues by swap volume and fees on the network.

The three pool types: AMM, CPMM, and CLMM

Raydium does not have just one kind of pool. Over time it has shipped three distinct designs, and knowing the difference helps you read what you are actually trading against.

• Standard AMM (the original v4 pools). These are the classic constant-product pools that follow the x · y = k formula, the same math behind Uniswap v2. They are battle-tested and still hold a lot of liquidity, but they are no longer the default for new pools.
• CPMM (Constant Product Market Maker). Raydium's newer constant-product pools. Same x · y = k invariant as the v4 AMM, but rebuilt to support the Token-2022 standard and multiple fee tiers. CPMM is the default for new pool creation and for tokens migrating in from the launchpad.
• CLMM (Concentrated Liquidity Market Maker). A more capital-efficient design where liquidity providers pick a price range instead of spreading capital across the whole curve. More on this next, because it is the one most people find confusing.

CLMM, in plain terms

In a classic constant-product pool, your deposited capital is stretched across every possible price from zero to infinity. Most of it sits idle at prices the token will probably never reach. Concentrated liquidity fixes that. A CLMM pool lets a liquidity provider concentrate their funds inside a chosen price band — say, only between $1.80 and $2.20 for a token trading near $2.00.

The payoff cuts two ways. For liquidity providers, the same dollars do far more work, so they earn more fees per unit of capital while price stays inside their range. For traders, the benefit is deeper liquidity clustered around the current price, which means lower price impact and slippage on a swap. The catch for the provider is that if price moves outside the band, their position stops earning fees and sits entirely in one of the two tokens until price returns. It is more powerful and more hands-on — better suited to stable pairs or active managers than to set-and-forget deposits. Raydium's rival Meteora built its reputation on a similar dynamic-liquidity idea.

The order book chapter (and how it evolved)

Raydium originally launched with a clever twist that set it apart: it was a hybrid AMM. On top of its own pools, it shared idle liquidity into a central limit order book — first Serum, and later OpenBook after Serum was forked and rebranded. The pitch was that Raydium pools could tap order-book depth and order-book traders could tap pool liquidity, giving everyone better pricing.

That hybrid wiring is now largely behind it. The OpenBook integration on the v4 pools has been deactivated, so those pools no longer post or share liquidity to the order book — they function as standalone AMMs. Raydium also shipped a streamlined swap interface that dropped the OpenBook market dependency entirely, cutting the number of on-chain accounts a swap needs and simplifying routing. The practical takeaway for a trader in 2026: when you trade on Raydium, you are trading against AMM pools, not a Serum-style order book.

LaunchLab and token graduation

Raydium does not just host liquidity for tokens that already exist — it can launch them. LaunchLab is Raydium's permissionless launchpad. Like other launchpads, a new token starts on a bonding curve, where price rises along a fixed formula as people buy in. Once the token raises enough SOL to fill the curve, it "graduates": the raised liquidity migrates into a Raydium pool (typically a CPMM pool) and normal AMM trading begins. The exact graduation threshold has shifted across versions and front-ends, so treat any single SOL figure you see quoted as a moving target rather than a constant.

LaunchLab's bigger strategic move is that it is built for third parties to plug into. The most prominent example is LetsBonk (also known as Bonk.fun), a community memecoin launchpad built on top of LaunchLab in partnership with the BONK community — covered in detail in our LetsBonk explainer. Tokens launched through these front-ends graduate into Raydium liquidity, which is how Raydium re-entered the launchpad fight that Pump.fun had dominated. If you want the head-to-head landscape, see Solana launchpads compared. Note that Pump.fun's own graduations now land on PumpSwap rather than Raydium, so "graduate to Raydium" is no longer universal.

Fees and the RAY token

Raydium charges a swap fee on every trade, and the rate depends on the pool. The legacy standard AMM pools sit at a flat tier, while CPMM and CLMM pools offer a range of fee tiers so pool creators can match the fee to how volatile or stable the pair is. The bulk of each fee goes to the liquidity providers who supply the pool. A portion is split between the protocol treasury and buying back the protocol's token, RAY. The exact split between LPs, treasury, and RAY buybacks, along with the basis-point tiers, varies by pool type — treat any single percentage you see quoted as pool-specific rather than a protocol-wide constant.

RAY is Raydium's native token. It is used for governance and captures part of the protocol's fee revenue through the ongoing buyback program. You do not need to hold RAY to trade or to provide liquidity — it is relevant if you want exposure to Raydium as a protocol, not a requirement for using the DEX. For a memecoin trader, RAY is mostly context, not a tool you reach for.

How most traders actually use Raydium

Here is the part that surprises people: you usually do not need to open Raydium's interface at all. The standard way to trade is through an aggregator like Jupiter, which scans Raydium alongside every other Solana DEX and splits your order across whichever pools give the best net price. So Raydium is often the venue your trade settles on even when the app you clicked was something else entirely.

That is exactly how a trading bot works too. When you fire a buy from a Telegram bot, it is not married to Raydium — it asks an aggregator for the best route, and Raydium pools are simply one of the destinations that route can hit. The upshot: you benefit from Raydium's deep liquidity without ever learning its UI, and you automatically get the better price if a different DEX is cheaper at that moment. To eyeball where a token's liquidity sits and which pool it lives in before you trade, a tool like DexScreener shows you the pool and its depth.

The risk: a Raydium pool is not a safety signal

This is the single most important thing for a memecoin trader to internalize. Raydium pool creation is permissionless: anyone can spin up a pool for any token, deposit whatever liquidity they like, and list it. Seeing a token "on Raydium" tells you it has a pool. It tells you nothing about whether that token is safe.

• Thin liquidity. A pool can hold a tiny amount of SOL, which means a small sell craters the price and your slippage is brutal. The pool existing does not mean it is deep.
• Pulled liquidity (rug pulls). If the deployer holds the LP position, they can withdraw it and leave you with a token you cannot sell into anything.
• Honeypots and trap tokens. Token-level tricks — freeze authority, transfer-fee or transfer-hook abuse, blocked sells — can exist regardless of which DEX hosts the pool. See Solana honeypot tokens for the common patterns.

The fix is not to avoid Raydium — it is to do your own checks. Confirm the liquidity is meaningful and, ideally, locked or burned. Look at holder distribution. Verify the token's authorities. A permissionless venue is a feature for builders and a responsibility for traders.

How MoonHydra fits

MoonHydra is a non-custodial Solana trading bot on Telegram, and it touches Raydium the same indirect way most traders should: it routes swaps through Jupiter, so when a Raydium pool offers the best price, that is where your order lands — and when another DEX is cheaper, it routes there instead. MoonHydra deploys no custom on-chain contracts of its own; your keys stay encrypted with AES-256-GCM. You trade any token by contract address, with limit orders, take-profit and stop-loss, copy-trading, DCA, and multiple sub-wallets, for a flat 1% per trade on both buys and sells, on top of the usual network and DEX fees. Optional RugCheck screening (off by default) can flag some of the trap-token risks above before you commit.

Bottom line

Raydium is Solana's foundational AMM: deep liquidity, three pool designs (standard AMM, CPMM, and concentrated-liquidity CLMM), a permissionless LaunchLab launchpad that powers front-ends like LetsBonk, and a home for many graduated tokens. Most traders reach it indirectly through an aggregator rather than its own UI — and that is fine. The one rule to carry away: a Raydium listing is proof of a pool, never proof of safety, so always check liquidity depth and token authorities before you ape in.

Next: read what an AMM is for the mechanics underneath all of this, what Jupiter is to understand how routing finds you the best Raydium price, and Solana honeypot tokens so a permissionless pool never catches you off guard. When you are ready to trade, MoonHydra is at t.me/moonhydrabot.
