Raydium,
explained.

Raydium is a decentralized exchange on Solana. Trades run against liquidity pools rather than an order book: anyone can swap tokens, add liquidity to earn trading fees, launch a token with LaunchLab or trade perpetual futures on Raydium Perps.

No. This is an independent community hub run by StonkBuilder Community. Raydium's own site is raydium.io, with its documentation at docs.raydium.io; Raydium does not operate or endorse this page.

The RAY mint on Solana is 4k3Dyjzvzp8eMZWUXbBCjEvwSkkk59S5iCNLY3QrkX6R. It is verified on Jupiter and has no mint or freeze authority, so no new RAY can be created. Tickers and logos can be copied, so compare the whole address before you swap.

The pool's fee, 0.25% on most pools and from 0.01% to 4% depending on the pool, plus a Solana network fee of about 0.002 SOL. Price impact and your slippage limit decide how far the price you get can move from the quote. Raydium shows them before you sign.

Usually the price moved past your slippage limit, the wallet was short of SOL for fees, or the route went stale on a busy network. The small network fee is still paid on a failed transaction; nothing else leaves your wallet. Transactions that went through can't be reversed.

A standard (CPMM) pool spreads liquidity over every price, so it always earns a share of fees. A concentrated (CLMM) pool puts your liquidity in a range you pick: more fees while the price is inside it, none while it is outside.

Raydium's token launchpad. A new token trades on a bonding curve, where each buy raises the price. When the curve reaches its target (85 SOL on JustSendIt, from 24 SOL on Advanced) the token moves into a Raydium pool automatically, with its liquidity burned or locked. Launchpads such as letsbonk.fun and StonkFun run on it too.

A way to lock liquidity for good and keep its trading fees. The LP tokens or position go into a program-owned lock, and you get a Fee Key NFT that claims the fees. The Fee Key can be transferred; the liquidity can never be withdrawn. It works on standard pools and full-range concentrated positions.

On standard and concentrated pools, 84% of each swap fee goes to the pool's liquidity providers, 12% buys back RAY and 4% goes to the treasury. The original AMM v4 pools charge 0.25%, of which 12% buys RAY. Bought-back RAY is held in a public wallet, not burned.

On the Staking page at raydium.io: deposit RAY and it earns RAY rewards, paid from new RAY emissions rather than from trading fees. The rate changes, so check it on the page before you stake.

Its programs have been audited by Kudelski Security, OtterSec, MadShield (now OShield), Halborn and Sec3, and it runs a bug bounty of up to $505,000 on Immunefi. In December 2022 an attacker who took over an AMM v4 admin key drained about $4.4 million from eight pools; Raydium compensated affected liquidity providers. Program upgrades now need 3 of 4 multisig signers and a 24-hour wait.
