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 launch 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.

Coins launched on BARN are the animals. The fees they generate are the eggs. The barn is where it all lives, safe and locked.

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.

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.

Launch a coin

From the Create page you set a name, ticker, image, and optional socials, then launch. 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 is it. From that block on, your coin is live and its liquidity is earning.

There are no presales and no team allocations baked into the launch. What you see is what trades.

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.

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.

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.

The yield source is swappable by design. When Ethena's sUSDe goes live on Robinhood Chain, the reserve can move to it for roughly 9%, with no redeploy.

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.

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.

Fees & economics

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

StreamAmountCreatorBuybackOps
Trading fee1% per trade40%42%18%
Reserve yield~3.85%/yr-70%30%
Creation fee$3 flat--100%

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 $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.

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.

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.

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.
