How Radius works

Launch memecoins on Raydium with 0% platform fees. Every token picks a 1% fee model: full burn, burn plus holder rewards, or burn plus creator. Every number on this page comes from the same constants and settings the code uses.

A launchpad that lives on Raydium

Radius launches memecoins on Raydium LaunchLab, Raydium's own bonding curve. When a curve fills it graduates into a Raydium CPMM pool. There is no separate exchange, no wrapped token and no Radius contract in the middle: tokens trade on Raydium from day one.

Radius takes 0%. Each token picks one of three ways to use a 1% fee on every trade, and that choice is fixed at launch. Under every model, 10% of that fee buys back and burns $RADIUS; none of it goes to a Radius wallet.

Lifecycle

How a launch works

Supply is 1,000,000,000 tokens with 6 decimals. 793,100,000 of them (79.31%) are sold on the curve. When the curve has raised 85 SOL, Raydium's own crank migrates it into a CPMM pool and the LP tokens are locked forever. Mint and freeze authority are removed at launch.

The three fee models

90% Burn

Buy back and burn this coin90%
$RADIUS buyback and burn10%

90% buys back the token and burns it. 10% buys back and burns $RADIUS.

Burn + Rewards

Buy back and burn this coin45%
Holders, in SOL45%
$RADIUS buyback and burn10%

45% buyback and burn, 45% paid to holders in SOL, 10% buys back and burns $RADIUS.

Burn + Creator

Buy back and burn this coin45%
Creator wallet, in SOL45%
$RADIUS buyback and burn10%

45% buyback and burn, 45% paid to the creator's wallet in SOL, 10% buys back and burns $RADIUS.

Fees that arrive as the token itself (the token side of the locked LP's fees) are burned in full under every model, so the keeper never sells the token into its own pool.

Follow the money

Where the 1% goes

1Someone trades
Every buy and sell on the curve pays 1% to this token's own LaunchLab platform vault, plus Raydium's 0.25%.
2Only this token's vault
Each token gets its own fee account and platform config, so fees from one token never mix with another.
3The keeper claims and splits
On a schedule it claims the SOL and splits it by the model committed at launch: 45% burns this coin, 45% goes to holders in SOL and 10% buys back and burns $RADIUS.
4Every step is public
Claims, buybacks, burns and payouts are normal Solana transactions, each linked on the token's page. Radius takes 0%; the 10% $RADIUS share is burned, not paid to anyone.

On the curve a buyer pays 1.25% in total: 0.25% to Raydium and 1% to the token's model. In the graduated pool it is 1.25% in total: the pool's 0.25% trade fee and the 1% creator fee. This build runs on devnet, where the graduated pool tier is 0.25% + 0.25% for testing; mainnet uses 0.25% + 1%.

Scope

Which trades pay the fee

Pays the fee

Every buy and sell on the token's bonding curve
Every swap in its graduated Raydium pool
From any app, bot or router: Raydium, Jupiter, a Telegram bot, all the same

Does not pay it

Trades on another pool someone else creates for the token (Meteora, Orca, a second Raydium pool)
Wallet to wallet transfers: the token has no transfer tax
Anything on other chains or bridges

Honest version

What is on chain and what the keeper does

Enforced on chain

1% on every curve trade: Raydium's LaunchLab program (the platform fee of a platform config that belongs to this one token)
1% on every pool trade: Raydium's CPMM program (the creator fee of the pool's fee tier)
Fees land in a vault only this token uses: Program-derived accounts of LaunchLab and CPMM
Liquidity can never be pulled: LaunchLab migration plus Raydium's Burn and Earn lock
The model you picked: The memo in the launch transaction, signed by your wallet

Done by the keeper

Claims the fees from the token's vaults on a schedule
Splits them by the committed model (the split is computed in the database from the model, not chosen by the keeper)
Buys the token back with the burn share, with a minimum output from reserves read on chain in the same run, and burns it
Pays holders and creators in SOL

Plainly: the keeper holds the keys to each token's fee account, so the routing after collection is not enforced by a program. What keeps it honest is that every step is a normal public transaction. Each token page lists every claim, buyback, burn and payout with its Solscan link, and anyone can reconcile the fee account's balance against that ledger. A fully trustless version needs a custom program to own the fee accounts and an audit first; that is planned, not live.

Vanity

Addresses that end in RAY

The mint address is ground in your browser, on your own device, across several cores at once. A case-sensitive RAY ending takes about 195,112 tries on average, usually about a second. The key is never sent anywhere and controls nothing once the token exists, because the launch removes mint and freeze authority.

Originals first

Copycats pay 1 SOL

Every coin launched on Radius is on record. When a new coin uses the same name, the same ticker or the same image as a coin that is already live on Radius, the launch stops at "This already exists" and shows the coins it matches, with a link to each.

You can still launch it, but only by paying the 1 SOL copycat fee to the Radius dev wallet, inside the same launch transaction. Change the name, ticker and image and it launches for free like any other coin.

Name
Compared after dropping case, spaces, punctuation and accents, and after folding look-alike letters and digits. "M A N T A", "manta!", "M4NTA" and MANTA spelled with a Cyrillic A are one name.
Ticker
The same rules, without the $. $MANTA, manta and MAN7A are one ticker.
Image
The server fingerprints every uploaded image from its pixels. A re-saved, resized or recompressed copy of a coin's image still matches it.

The fee shows in your wallet as a plain SOL transfer before you sign, and the site checks on chain that it was paid before the coin is listed. It is the only time Radius is paid anything: originals launch and trade at 0%.

Every model

10% buys back and burns $RADIUS

Under every model, 10% of each coin's SOL fee income (that is 0.1% of its trading volume) buys $RADIUS, the Radius token, on the open market and burns it. The other 90% follows the coin's model. None of it goes to a Radius wallet: Radius still takes 0%.

The keeper runs the $RADIUS buyback about every 15 minutes, once a coin's $RADIUS share reaches 0.005 SOL. Every buy and burn is listed on that coin's page and on Analytics, with its transaction.

$RADIUS buybacks start when $RADIUS launches; until then this share waits in the coin's own fee account.

Holders

Holder rewards (Burn + Rewards)

45% of the fee buys back and burns the coin, 45% is paid to holders in SOL and 10% buys back and burns $RADIUS. Holder rewards are pushed straight to wallets. There is nothing to claim. Check any wallet on the rewards page.

Held for at least 5 minutes
A wallet shares in a payout only if it held for at least 5 minutes, weighted by its smallest balance in that time. Wallets that sell before a payout get nothing; their share goes back to current holders.
Minimum balance
At least 100,000 tokens through that time.
How often
About every 5 minutes, once the holder pot reaches 0.01 SOL. Up to 1,000 holders per payout, largest first.
Dust carries over
Shares under 0.0001 SOL are not sent yet. They stay owed and are added to the next payout.
Wallets only
Program vaults and PDAs (the curve, the pool, lockers, multisig vaults), the fee account and the burn address are left out.
Paid in SOL
A normal SOL transfer to each wallet. The network fee is paid by the operator, not by you.

Creators

Creator payouts (Burn + Creator)

45% of the fee buys back and burns the coin, 45% is sent in SOL to the wallet that signed the launch and 10% buys back and burns $RADIUS. Creator payouts go out about every 5 minutes once at least 0.005 SOL is waiting. Every payout shows on the token page and on your creator dashboard.

Burns

How buybacks run

About every 5 minutes the keeper spends a coin's burn share once it reaches 0.005 SOL, at most 2 SOL per run. Each buy has a slippage cap of 1% and a price impact cap of 1.5%, with the minimum output worked out from pool reserves read on chain in the same run. The tokens bought are burned with the SPL burn instruction, so the supply really goes down. The $RADIUS buyback works the same way, on its own schedule.

Risks

Memecoins are volatile and most go to zero. Only use money you can lose.
Burns and rewards do not guarantee any price. They depend on trading volume, which can stop.
The keeper holds each token's fee account keys. Every action is public and linked, but routing after collection is not enforced by a program yet.
Raydium's programs are outside our control. If Raydium changes or pauses them, launches and fees can be affected.
Smart contract, RPC and wallet bugs exist. Check every transaction your wallet shows you before signing.
Anyone can create other pools for a token. Trades there do not pay the model fee.

Questions

FAQ

Does Radius take a cut?

No. Radius takes 0% of launches and 0% of trades. 10% of each coin's 1% fee (0.1% of volume) buys back and burns $RADIUS; none of it goes to a Radius wallet. Raydium charges its own fees, listed in the table above. The one exception is a copycat: a coin with the same name, ticker or image as a coin already on Radius pays a 1 SOL copycat fee to the Radius dev wallet.

Can the creator change the model later?

No. The model is written into the memo of the launch transaction, which the creator signs. The keeper reads it back from the chain before it moves any money for that token.

Can the liquidity be pulled?

No. There is no liquidity to pull on the curve, and at graduation Raydium moves the curve into a pool whose LP is locked forever.

What if the keeper stops?

Fees keep piling up in the token's own vault. Nothing is lost; the keeper claims them when it runs again.

Does burning make the price go up?

Not necessarily. Burns reduce supply, but price depends on what people buy and sell. Nobody can promise a price.

Is every address really ending in RAY?

Only if the launch says so. If the address is not found in time you can retry or launch with a plain address, and the site never claims a RAY ending it does not have.

Can I launch a coin that is already on Radius?

Yes, for 1 SOL. If your name, ticker or image matches a live coin, the launch shows "This already exists" with the matching coins. Launch anyway and the 1 SOL copycat fee is paid to the Radius dev wallet in the same transaction. Change the name, ticker and image and it is free.
