Basics

​

What is Raydium?

A decentralised exchange (DEX) on Solana. You use it to swap tokens, provide liquidity, farm rewards, and launch tokens — all without an account or a centralised intermediary. See introduction/what-is-raydium.

​

Do I need an account?

No. Your Solana wallet is your identity. There’s no signup, no KYC (on Raydium itself), no password.

​

Is there a mobile app?

Raydium doesn’t ship its own app. Use the built-in dApp browser of any reputable Solana wallet that has one — raydium.io loads inside it.

​

Which wallet should I use?

Any reputable, non-custodial Solana wallet that supports versioned (V0) transactions. See getting-started/choosing-a-wallet for the features that matter when picking one.

​

What is RAY?

Raydium’s native SPL token. You can stake RAY in the Raydium app and track RAY buybacks from protocol fees. You do not need RAY to swap or provide liquidity — it’s optional. See ray/index.

​

Fees

​

How much does a swap cost?

Two kinds of fee:

• Trading fee: 0.25% on most pools (some tiers offer 0.01%, 0.05%, or 1%). Split between LPs and protocol. Charged on every swap.
• Network fee: ~0.0005–0.002 SOL (a few cents) for the Solana transaction itself. Paid in SOL.

​

What’s the “priority fee”?

An optional tip to Solana validators to prioritise your transaction during congestion. The Raydium UI has a priority-fee selector (Normal / Turbo / Max). On a quiet network, pick Normal. On a congested network, Turbo prevents your transaction from getting dropped. See integration-guides/priority-fee-tuning.

​

How much SOL do I need for fees?

Budget 0.02 SOL as a minimum safety buffer. One swap costs ~0.002 SOL; you don’t want to run down to exactly zero.

​

Why did the trade fee look bigger than 0.25%?

If either token is Token-2022 with a transfer fee, the total cost compounds: pool fee + transfer fee + another transfer fee on output. See reference/fee-comparison.

​

Transactions

​

My transaction failed. Why?

Most common causes:

1. Slippage exceeded — price moved between quote and execution. Raise slippage (0.5% → 1% or 2%) and retry.
2. Insufficient SOL for fees — always leave at least 0.02 SOL above your swap amount.
3. Stale route — the pool changed (unlikely in short windows). Refresh the page and retry.
4. Congestion — Solana was overloaded; raise priority fee.

The transaction fee is still paid on a failed transaction (that’s how the network charges for the wasted compute). The trade itself does not happen.

​

How do I find a transaction?

• Your wallet’s Transaction history tab.
• The Raydium UI’s confirmation toast links to an explorer.
• Search your wallet address on solscan.io or explorer.solana.com.

​

What’s the transaction signature / hash?

A base58 string (~88 characters) that uniquely identifies a Solana transaction. It’s shown in your wallet log and on explorers.

​

Can I cancel a pending transaction?

Usually no. Solana transactions either land or expire (in ~30 seconds) — there’s no mempool to cancel from. If a transaction is stuck pending, wait 30 seconds; it will either confirm or drop.

​

Can I reverse a completed transaction?

No. Solana transactions are final. If you sent funds to the wrong address, they’re gone unless the recipient voluntarily returns them.

​

Tokens

​

How do I know a token is legitimate?

• Look for the verified badge in the Raydium UI.
• Cross-check the mint address against known canonical addresses (reference/program-addresses for protocol addresses; see getting-started/trust-and-safety for common tokens).
• Check the token on solscan.io — look at holder count, mint authority, freeze authority.

​

What’s wrapped SOL?

SOL, the native token, is not an SPL token — the Solana runtime treats it specially. For pools and many dApps, you need SOL in SPL form (“wrapped SOL”, So11111111111111111111111111111111111111112). Your wallet and Raydium wrap and unwrap automatically. Occasionally small dust amounts of wSOL remain; they’re unwrapped on your next swap.

​

I see two versions of the same token (e.g. USDC and USDC.wh). Why?

• USDC = native USDC issued by Circle. Preferred.
• USDC.wh = USDC bridged from Ethereum via Wormhole; a different token on-chain.

They trade at slightly different prices because they live in separate pools. Raydium will tell you which you’re holding; prefer native for most use cases.

​

What’s an LP token?

When you deposit into an AMM pool, you get LP tokens (Liquidity Provider tokens) representing your share. Burn them to withdraw your share plus accrued fees.

• CPMM / AMM v4: LP tokens are fungible SPL tokens. You can stake them in a farm, send them to another wallet, etc.
• CLMM: your position is a position NFT, not a fungible LP token. You can transfer it, but can’t stake it in Farm v6.

See user-flows/add-remove-liquidity.

​

How do I close an empty token account?

Some wallets offer a “Close” or “Burn empty accounts” button. Each closed account returns ~0.002 SOL of rent. Safe for standard SPL tokens; don’t close Token-2022 accounts with transfer hooks (hook program runs on close).

​

LP & farming

​

What’s impermanent loss?

The value gap between holding LP tokens and simply holding the two underlying tokens. For correlated pairs it’s negligible; for volatile uncorrelated pairs it can be 10–50% over a year. See algorithms/impermanent-loss.

​

Should I use CPMM or CLMM?

CPMM = set-and-forget, lower fee capture per dollar. CLMM = active management, higher fee capture per dollar, more IL risk. Full decision guide: user-flows/choosing-a-pool-type.

​

Can I stake my CLMM position?

CLMM positions can’t be staked in Farm v6 (farms accept only fungible LP tokens). However, some CLMM pools have built-in farm rewards that accrue to the position directly. See products/clmm/fees.

​

What’s Burn & Earn?

A mechanism for permanently locking an LP position while retaining a Fee Key NFT that continues to collect trading fees. Used heavily by LaunchLab graduated tokens. See user-flows/burn-and-earn.

​

LaunchLab specifically

​

What is LaunchLab?

Raydium’s token-launch program: a bonding curve that graduates into a full Raydium pool when it hits a funding target. See products/launchlab/overview.

​

Can I launch a token myself?

Yes, via raydium.io/launchlab or a third-party platform built on LaunchLab. See user-flows/launch-token-launchlab.

​

What are creator fees?

LaunchLab splits fees into a pre-graduation pool (claimed from a vault) and a post-graduation pool (claimed via a Fee Key NFT from Burn & Earn). See products/launchlab/creator-fees.

​

Perps

​

Does Raydium have perpetual futures?

Yes — Raydium Perps, powered by Orderly Network. Gasless CLOB trading with up to 100× leverage. See products/perps/index.

​

How is it different from spot swap?

Perps are leveraged derivatives — you trade price exposure, not the actual token. Gasless (orders don’t send a Solana transaction). See products/perps/trading-basics.

​

Referrals

​

How do referrals work?

Share a Raydium swap URL with your wallet as referrer; you earn 1% of every swap through the link. See user-flows/referrals-and-blinks.

​

What are Blinks?

Shareable one-click transaction links. When a referral link is posted on X (Twitter), compatible wallets render it as an interactive widget that lets the viewer swap without leaving the post.
