Built against pump and dump.
The first token launchpad we know of where every launch waits in one on-chain line and goes live in order, at most 5 a minute. No fee buys a better place in that line.
Every token opens with the same protections. While it is on its curve, one wallet holds at most 0.5% of supply, the buys in one block add up to at most 1.5%, and the dev buys on that open curve under the same caps as you. The tax is fixed at launch, the liquidity is locked for good on Uniswap v4 at graduation, and selling is never limited.
The harbor takes turns
Every launch registers on-chain first and waits its turn. The contract only lets the head of the line launch, so the order launches go out in is the order they were registered in.
One line, first come
A registration takes the next place in line and keeps it. The contract only lets the head of the line launch, so nobody can pay to jump it, and the owner, the platform and the keeper cannot reorder it. A cancelled registration is skipped, never overtaken.
First registered, first launched5 slots a minute
A round is one minute of block time. Once 5 launches have landed in it, the next one waits for the next minute. A round does not wait to fill up: the head of the line launches as soon as someone runs it, so a quiet minute costs nobody their place.
5 a minute · 50 every ten minutes at mostAnyone can run the line
The platform keeper runs the head of the line while the round has room. If it goes quiet, any wallet can run it from the queue page with nothing but an RPC. The contract checks the order and the round, so running it buys the runner no place and no priority.
Permissionless execution · no priority for the runnerHold the light to launch one
A place in line is not for sale. It asks for two things that are hard to fake in bulk: $BEACON held while the registration waits, and an X account proven to be yours.
The $BEACON is held, never spent and never taken. Once the registration resolves, launched or cancelled, you claim all of it back.
- Hold 1,000 $BEACON to registerthe queue holds it with your registration and returns all of it once the registration resolves
- Prove you control an X accountBeaconHarbor never sees your password, and the account is shown on the launch it registered
- No registration feeyou pay network gas in USDC for your own transactions, and nothing else
- One open registration per wallet and per X accountone person with a script cannot fill the line
- Cancel while you waitcancelling gives up the place in line, and everything the registration holds becomes claimable
- The balance is checked when you registerand it cannot drop before your turn, because the queue is holding it for you
$BEACON lights first
$BEACON is the first launch on BeaconHarbor, registered by the founder wallet written into the contract. It rises on the same curve as every other beacon, with the same choice of token type and tax, and standard registrations open the moment it trades.
- Ticker
- BEACON, reserved on-chain for the genesis launch
- Registered by
- The founder wallet written into the contract, and no other address
- Rules
- The same curve as everyone, Normal with no tax or Tax 1% to 10% a side split 70/30
- Standard registrations
- Closed until $BEACON trades, then open to wallets that meet the holding rule and prove an X account
Before $BEACON trades, the queue takes no other registration and the ticker BEACON is refused for everyone. After it trades, a wallet that holds 1,000 $BEACON and proves an X account can register. The live state of genesis is on the queue page, read from the chain.
First Light
First Light is the idea of a pledge window before a curve opens, where everyone who pledges enters at one price and the rest is refunded on-chain. It is on the roadmap and it is not built. Nothing is open to pledge, and no date is set for it.
Every launch today runs the queue and the curve described on this page.
Rules no token here can break
Every token trades on its own bonding curve, priced in USDC, and its contracts check these rules on every buy and every transfer until graduation moves it to Uniswap v4. The caps and tax limits are the same for the first launch and the five thousandth, and no one holds a switch that turns them off early for one token.
- 01Seed
The beacon lights with its whole supply on the curve. Anyone can buy in USDC, the creator included, priced by the same curve with no discount. While the beacon is on its curve, no wallet can hold more than 0.5% of supply, and the creator's own buy is capped at 0.5% inside the launch.
max wallet 0.5% · dev buy 0.5% at most · no presale - 02Rising
Each buy adds a point of light and pushes the price up the curve. One block sells at most 3 max wallets' worth of tokens, 1.5% of supply, shared by every buyer in that block. Both caps hold for the whole curve, never widening and never tightening, and selling is never limited.
1.5% of supply per block · caps hold until graduation · selling never limited - 03Full light
At 6,000 USDC raised the curve is full. Graduation happens inside the buy that fills it, at the same price the curve reached, so there is no pause and no step in the price.

The pool burns the tokens the last price does not need. BeaconHarbor's graduator contract puts the raised USDC and the rest into a new TOKEN/USDC pool on Uniswap v4, at that same price, as one full-range position it owns and has no function to remove, so the liquidity is locked for good. From there the token trades on Uniswap, through this site or any Uniswap interface, and appears on DexScreener by itself. The max wallet and the block budget end, so anyone may buy any amount, and with no mint function the supply can only shrink. A tax token keeps paying its creator on every swap: 1% to 10% a side, 70% to the creator and 30% to the protocol, taken and claimed in USDC through BeaconHarbor's hook contract. A Normal token pays no tax, on the curve or on Uniswap.

What is honest about this
The parts a reader should check before trusting anything here, said plainly instead of buried.
No audit yet
The contracts have not been audited. That is the state today. When an audit exists, the firm and the report link appear here and on every page that talks about money.
Live on Arc mainnet
Every balance here is real money. Every rule on this page is enforced by the contract, not by a promise from us, and every transaction is on-chain and visible.
The numbers come from the chain
Rounds, launches, trades and holder counts are read from Arc. Where a panel shows an example instead, it says so on the panel. We publish no metric the chain does not back, and no partner, listing or audit that does not exist.
Your beacon, in the order you registered.
Fill the six steps, hold 1,000 $BEACON, prove your X account, and take the next place in line. Your beacon lights when its turn comes, in a round that holds 5 of them.
There is no registration fee. You pay network gas in USDC for your own transactions. The contracts have not been audited.
