The barn handbook

BARN is the memecoin launchpad on Robinhood Chain where the liquidity behind every coin actually earns. Launch an animal, trade it, and collect the eggs.

On every other launchpad, the money sitting in a coin's liquidity pool just sits there. It lets people trade, and that is all it does. BARN changes one thing: the cash side of every pool is a dollar that earns yield. The liquidity works while it waits.

Everything else feels familiar. You create a coin in one click, it is instantly tradable on Uniswap V3, and the liquidity is locked forever so it can never be pulled. The difference is that the locked cash is productive, and the yield plus the trading fees flow back into the ecosystem and into $BARN, the token at the center of the barn.

Why it matters: across a coin's whole life, that "dead" cash usually just idles. On BARN it compounds instead, and because the liquidity is locked, it keeps compounding for as long as the coin exists. Multiply that across every coin in the barn and it becomes a real, growing engine underneath the whole platform, not a gimmick on top of one.

BARN is built for two people: the creator who wants their coin's liquidity working for them and a real cut of the fees, and the trader who wants a launchpad where the plumbing is honest, the liquidity can't rug, and the floor is real.

How BARN works

Three moving parts, kept deliberately simple:

1. Instant listing

Creating a coin deploys a standard token and seeds a Uniswap V3 pool in a single transaction. It is tradable immediately, no bonding curve, no waiting to graduate.

2. Locked, productive liquidity

The liquidity position is locked permanently in a locker contract. Nobody can pull it. The cash side of the pair is bUSD, a yield-bearing dollar, so the locked liquidity earns while it sits.

3. Fees flow home

Every trade pays a 1% fee. Half goes to the coin's creator as eggs, half to the house, and the yield stacks on top. The house share plus yield buys back and burns $BARN.

That is the entire machine. There is no bonding curve to babysit, no graduation step that can fail, and no liquidity that can quietly disappear. A coin either trades or it does not, and either way the liquidity behind it stays locked and keeps earning. Everything complex is kept off the contract and handled by automation, so the on-chain part stays small, simple, and hard to break.

The barn & the eggs

The branding is the mechanic. Every coin you launch is an animal that lives in the barn. Every fee it generates is an egg. As a creator you collect the eggs your animals lay. As a holder of $BARN you benefit from every animal in the barn, because their eggs feed the token.

The more animals in the barn and the more they trade, the more eggs get laid, and the more the whole barn is worth. It is a simple loop, and it is the entire point.

So the eggs are not just a cute label. They are the two real income streams every coin produces, the trading fees and the yield on its locked reserve, split between the creator, the buyback of $BARN, and keeping the platform running. When people talk about eggs, they mean actual on-chain revenue moving to real wallets.

Create a coin

No code, no setup. On the Create page you set a name, ticker, image, and optional socials, then hit create. In one transaction BARN:

• deploys a clean ERC-20 with no hidden mint or owner tricks,
• creates the Uniswap V3 pool paired against bUSD at the 1% fee tier,
• adds the initial liquidity and locks the position permanently.

You pay the network cost plus a flat $3 creation fee that goes to running the platform. That is it. From that block on your coin is live, tradable, and its liquidity is already earning yield.

The moment it is created, you become its creator on-chain, which means you earn 40% of every trade's fee on it, forever. Those eggs pile up in the contract and are yours to claim whenever you want. Nothing about the coin can be changed after launch, so holders know exactly what they are buying from block one.

Trade a coin

Every coin has its own page with a live chart, a buy/sell panel, and full stats. You trade with normal ETH or USDG, exactly like anywhere else. Behind the scenes a one-click zap wraps your dollars into bUSD so the pool stays productive, and unwraps on the way out. You never have to think about it.

Because liquidity is locked and the pool holds a yield-bearing reserve, the floor under every coin is real, and it grows over time as the reserve earns.

Practically, trading feels identical to any other launchpad: pick a coin, see its chart and stats, buy or sell in a click. The difference is invisible and in your favor. The 1% you pay per trade does not vanish into a black hole, it becomes eggs for the creator and buyback fuel for $BARN, and the cash backing the coin you just bought is quietly earning yield the whole time you hold.

Claim your eggs

If you launched a coin, you earn 40% of every trade's fee on it. Those eggs accrue in the contract and you claim them any time from your Profile, straight to your own wallet. The split is enforced on-chain at the moment you claim, so there is nothing to trust and nothing that can be withheld.

Your liquidity keeps earning yield the entire time, whether or not you have claimed. Nothing you do resets it.

Eggs accrue trade by trade, so a coin that gets volume is laying eggs into your balance continuously. There is no vesting, no lockup, and no minimum. You can let them pile up and claim in one go, or claim often, whatever you prefer. The only cost to claim is the network gas for the transaction.

Profiles & following

BARN has real accounts. You sign in with your wallet, no password and nothing to remember, and you get a profile that lives at barn.fun/profile/your-name.

Usernames

On your first sign-in you get a randomly generated username so your address is never the thing people see. You can change it any time to whatever you want. Usernames are unique across all of BARN, enforced at the database level, so no two farmers can share one and nobody can impersonate you by case-swapping it.

Following

You can follow other farmers to keep an eye on what they launch and trade. Every profile shows its follower and following counts, and your own profile is where your created coins and claimable eggs live.

Sign-in & sessions

Signing in is a single wallet signature, which the server verifies cryptographically, no password is ever created or stored. Your session persists so a refresh never logs you out, and there is a one-tap disconnect whenever you want out. Everything stays non-custodial: signing in proves you own the wallet, it never gives BARN any control over it.

Productive liquidity

This is the whole idea. On a normal pool, the cash side (usually wrapped ETH) is dead weight. It enables trades and earns nothing on its own. On BARN, the cash side is bUSD, which is continuously lent out on Morpho earning around 3.85% a year.

So each coin's locked liquidity produces two streams at once: the trading fees from swaps, and the lending yield on the reserve. Same locked-forever safety as the pads people already trust, except the money is no longer asleep.

To put a number on it: if a coin has $100k of locked liquidity, that reserve throws off roughly $3,850 a year at current rates, on top of whatever the trading generates, for as long as the coin exists. One coin is a rounding error. Hundreds of coins, all locked and all earning, compound into a serious base of yield flowing through the platform every single day.

bUSD, the earning dollar

bUSD is BARN's yield-bearing dollar. Think of it as USDG that never sits still. When USDG goes into bUSD, it is supplied into a permissionless Morpho lending market, and the interest borrowers pay accrues to bUSD, so one bUSD is slowly worth more than one dollar.

Traders never hold or manage bUSD directly. The app zaps in and out for you, so from the outside you are just buying and selling with ordinary dollars. bUSD only exists under the hood, as the productive reserve inside every pool.

The pattern is the same one behind well-known yield tokens like sUSDe or lending-pool receipts: a token that represents a deposit and grows as that deposit earns. bUSD is redeemable for its underlying dollars plus the accrued interest at any time, and the reserve it lends into is deliberately swappable, so if a better yield source appears on Robinhood Chain, bUSD can move to it without any coin needing to relaunch.

Locked liquidity

When a coin launches, its Uniswap V3 liquidity position (an NFT) is transferred into a locker contract and kept there permanently. The principal can never be withdrawn by anyone, including us. That is the anti-rug guarantee, and it is enforced by the contract, not by a promise.

The one thing the locker can do is let fees and yield be collected out to the fee splitter, while the principal stays locked. That single capability is what makes the whole model work, and it is the piece we build and test first, before anything else ships.

This is deliberately the hardest part to get right, and the part most launchpads quietly get wrong. If the locker cannot release fees, the revenue is stranded forever; if it can release principal, the liquidity is not really locked. BARN's locker threads that needle: principal is mathematically stuck, fees and yield always flow. It is tested against real swaps on testnet before a single coin launches on mainnet.

Fees & economics

There are three income streams, and everything the house earns points back at $BARN or keeps the lights on.

The creator keeps 40% of their coin's trading fees as eggs. The house takes the rest, and the house pot (its share of fees plus all the yield) is split 70/30 between buying back and burning $BARN and funding operations. Creation fees go entirely to ops. Every split is adjustable and enforced on-chain.

The design goal behind these numbers is alignment. Creators earn enough that BARN is worth launching on over a launchpad where liquidity earns nothing. The buyback share ties the success of every coin directly to $BARN, so the token is a claim on the whole pad rather than a bet on one coin. And the ops slice keeps the lights on without needing token emissions or a treasury raid. Nothing here is inflationary, it is all real revenue being routed.

The $BARN flywheel

$BARN is the token at the center of the barn, and it is a claim on the entire pad's activity. Because liquidity is locked forever, every coin ever launched keeps generating fees and yield indefinitely, and a slice of all of it is continuously used to buy $BARN off the market and burn it.

The loop: more coins launched means more locked liquidity earning, which means more fees and yield, which means more $BARN bought and burned, which draws more attention, which brings more launches. Coin number one and coin number five hundred both keep feeding the same token, forever.

The key property is that the base only grows. Because liquidity is never unlocked, a coin that launched months ago is still generating yield and still feeding buybacks today. Most launchpad tokens are a bet on this week's volume. $BARN is a claim on every animal that has ever entered the barn, and that herd only gets bigger.

Roadmap

BARN starts on Robinhood Chain, but the barn is meant to span chains. The plan, roughly in order:

Phase 1 - Live on Robinhood Chain

The launchpad itself: one-click coins, permanently locked liquidity that earns yield, the 40/60 fee split, creator eggs, and $BARN with its buyback. Real accounts, usernames, and following. This is shipping now.

Phase 2 - Bigger yield

The reserve moves from base lending (~3.85%) to Ethena's sUSDe (~9%) the moment it goes live on Robinhood Chain, with no relaunch needed. Every locked pool starts earning more overnight.

Phase 3 - Wormhole $BARN across chains

$BARN gets bridged out via Wormhole so it lives natively on Solana, Ethereum, BNB, and Base, not just Robinhood Chain. One token, many chains, so anyone anywhere can hold and trade the barn's core asset. The buyback keeps feeding the same $BARN no matter which chain you hold it on.

Phase 4 - Launch coins on more chains

Eventually the launchpad itself opens on other chains, so you can raise an animal on Solana or BNB with the same productive-liquidity engine underneath, all feeding back into one $BARN.

Robinhood Chain

BARN runs on Robinhood Chain, an Ethereum layer 2 built on Arbitrum technology, using ETH for gas. It is fully permissionless: anyone can deploy and interact without approval. It launched in mid-2026 and its early volume has been driven overwhelmingly by memecoins, which is exactly the ground BARN is built for.

The yield underneath BARN comes from Morpho, which is live and deep on the chain, so productive liquidity is possible today, not someday.

Practically, that means BARN inherits a fast, cheap, fully EVM environment with real lending liquidity already in place. Coins deploy with standard tooling, trades confirm quickly, and the reserve has a deep, battle-tested market to earn in. As the chain's DeFi grows, so do BARN's options for where the reserve earns.

Security

BARN is non-custodial. It never holds your keys or your funds. You trade and claim from your own wallet, and the contracts only ever move value according to rules that are fixed on-chain.

• Locked liquidity is enforced by the locker contract, not by trust.
• Fee splits settle on-chain at claim time, so no share can be withheld.
• Role-separated wallets. The deployer, the ops treasury, and the automated keeper are separate and never share keys. The keeper can only harvest fees and run buybacks, never touch principal.
• Clean tokens. Launched coins are standard ERC-20s with no owner backdoors or hidden mint.

Sign-in never touches a password. You authenticate by signing with your wallet or through an OAuth provider, so there is no password database to breach. On the backend, all data is handled through parameterized queries, secrets live server-side and encrypted, and the only automated key that exists (the keeper) is scoped so tightly it can do nothing but harvest fees and run buybacks. The design assumption is simple: BARN should never be able to lose your money, because it never holds it.

Risks

Memecoins are volatile and most go to zero. BARN makes launching and trading safer at the plumbing level (locked liquidity, clean tokens, real yield) but it cannot make any individual coin a good investment. The reserve yield is variable and depends on lending markets. Smart contracts carry inherent risk even when audited. Only put in what you are comfortable losing, and nothing here is financial advice.

FAQ

Is the liquidity really locked?

Yes, permanently, in a locker contract. The principal cannot be withdrawn by anyone. Only fees and yield can be collected out.

Where does the yield come from?

The bUSD reserve is lent on Morpho, and borrowers pay interest. That interest is the yield. It is real lending income, not token emissions.

What do I earn as a creator?

40% of every trade's fee on your coin, claimable any time to your wallet as eggs.

What is $BARN for?

It is the token the whole pad feeds. The house share of fees and yield continuously buys it back and burns it.

Do I need to understand bUSD to trade?

No. You trade with normal ETH or USDG. bUSD is handled automatically under the hood.
