KEIBA

Launch a coin. Race it by live market cap. Get paid in ETH every hour.

KEIBA is a permissionless launchpad layer on Pons v2, on Robinhood Chain. Every coin launched through KEIBA is a standard Pons v2 token paired with ETH, with its creator fee routed to the KEIBA keeper.

All KEIBA coins run in one perpetual race, ranked by live market cap. Every hour, starting one hour after the first coin launches, the purse pays real yield in ETH — funded by trading fees, not emissions — to the holders of the top 3 coins. There is nothing to stake and nothing to claim: payouts are pushed straight to holder wallets, with every transaction settled on-chain.

How the race works

Every eligible coin launched through KEIBA is a runner from the moment its launch transaction confirms. The keeper prices every runner from on-chain state and ranks the field by live market cap. There are no heats, rounds or entry fees: the race is perpetual.

• The track shows the top 8 coins by live market cap. Each horse's distance down the track is its market cap relative to the leader.
• Entries lists every runner, with its live market cap, creator fee, its share of the next payout and the ETH already paid to its holders.
• The podium is the top 3 at any moment. The podium at the payout snapshot block is the podium that gets paid.

Positions change with every trade. A coin that is 4th at 12:59 and 3rd at the snapshot is paid; a coin that drops out of the top 3 before the snapshot is not.

Launching a coin

Launching is permissionless: anyone with a wallet on Robinhood Chain can launch from Launch a coin on the main page. Every coin is a fair launch on the Pons v2 bonding curve — no presale, no allocation outside the curve — and the page never takes custody of your funds: you sign the launch in your own wallet.

1. Describe the coin. Name (1–32 characters), ticker (1–10 letters or digits), an optional description, website, X and Telegram links, and an image (PNG, JPEG, GIF or WebP, up to 2 MB). The image is pinned to IPFS.
2. Pick the creator fee. 1% to 10%, charged on every trade on top of Pons's 1% base fee.
3. Set your first buy in ETH (any amount above zero).
4. Sign one transaction. KEIBA prepares a single launchAndBuy call to the Pons forwarder. Token creation and your first buy execute atomically in one transaction, so no one can buy ahead of you, and the dev buy is exempt from the snipe tax. The transaction value is your first buy plus the Pons launch fee, both shown in your wallet before you sign.

The creator receives no share of the creator fee. What a creator gets is a coin whose holders earn ETH every hour it stays on the podium.

Fee flow

KEIBA is fee-sharing by design: the creator fee of every runner is split between the holders of the top coins, the $KEIBA burn and the protocol. Every buy and sell of a KEIBA coin pays the Pons 1% base fee plus the coin's creator fee. The creator fee accrues to the keeper through Pons (the fee escrow and fee sweeps), and the keeper books each credit from on-chain events before spending any of it.

Runner creator fees

$KEIBA's own creator fees

• The protocol share of every credit is settled first, before any other spend.
• The buyback-and-burn share buys $KEIBA on the market and burns it. Burned supply never comes back, so the burn is deflationary; running totals are on the main page.
• The Pons 1% base fee goes to Pons, not to KEIBA.

Payouts

The purse is paid out as real yield in ETH, on a fixed hourly schedule, with on-chain settlement.

• When: every hour, starting one hour after the first coin launches (the block time of that first launch sets the clock: first launch at 14:23 means payouts at 15:23, 16:23, and so on). The countdown on the main page shows the next one.
• Minimum purse: a payout runs only if the purse holds at least 0.1 ETH. Otherwise nothing is paid that hour and the purse rolls over to the next hour, still growing.
• Split: 50% to the 1st coin, 30% to the 2nd, 20% to the 3rd, by rank at the snapshot block.
• Who is paid: each coin's share goes to its holders pro-rata to their token balance at the snapshot block.
• Excluded balances: the bonding curve and the Pons pool contracts, burn addresses, the keeper, the payout contract and the $KEIBA contract are never paid.
• Smart wallets: EIP-7702 wallets count as holders like any other wallet.
• Small shares: a share under 0.0001 ETH is not dropped. It accrues as credit to that wallet and is paid once the wallet's total crosses the minimum.
• Delivery: ETH is pushed to holders through a batch payout contract, in batches of up to 150 wallets. Every batch has a unique id and the contract refuses an id it has already paid, so no batch can ever be paid twice.

Every paid hour is listed under Results and Payouts on the main page, with links to its transactions on Blockscout.

Eligibility

The keeper checks every launch against the on-chain launch record. A coin races only if all of these hold:

• its creator fee recipient is the KEIBA keeper;
• buyback is off;
• it is paired with ETH;
• its creator fee is between 1% and 10%;
• no change of fee recipient is pending;
• it is not $KEIBA itself.

Coins launched through the KEIBA launch dialog meet all of these by construction. If a runner's fee recipient ever changes, or a change becomes pending, the coin is removed from the race and its holders stop receiving payouts.

Security & transparency

• Non-custodial: KEIBA never holds or moves your tokens. You never approve a KEIBA contract to spend anything; payouts arrive as plain ETH transfers.
• Transparent: every payout is an on-chain transaction, linked from the site to Blockscout.
• Owner share first: the protocol share of each fee credit is settled before any other spend.
• Nothing paid twice: the payout contract rejects a batch id it has already paid, so even a resent transaction cannot pay twice.
• Booked from chain events: fees are booked from on-chain fee events after 20 block confirmations, not from estimates.
• Trust-minimized launches: the launch transaction is built from your inputs and signed in your own wallet; you can inspect it before signing.

The keeper is an automated service operated by the KEIBA team. It holds the purse and the burn bucket between payouts, and it is the only account allowed to call the payout contract.

$KEIBA

$KEIBA is the main token of KEIBA, launched on Pons v2 like every runner. It is not in the race and its holders are not paid from the purse.

• 10% of every runner's creator fee buys and burns $KEIBA.
• $KEIBA's own creator fees go 50% to buyback & burn and 50% to the protocol.
• More runners and more volume mean more $KEIBA burned.

FAQ

Do I need to claim my payout?

No. It is pushed to your wallet in ETH. Just hold a top-3 coin when the hourly payout snapshot is taken.

Why didn't I get paid this hour?

The usual reasons: the purse was under 0.1 ETH, so it rolled over; your coin was not in the top 3 at the snapshot block; you bought after the snapshot; or your share was under 0.0001 ETH and was added to your credit instead (it is paid once your total crosses the minimum).

What is the minimum?

The purse must hold 0.1 ETH for an hour to pay out, and a single wallet payment must be at least 0.0001 ETH; anything smaller accrues as credit.

What happens if the purse is under 0.1 ETH?

Nothing is lost. The purse rolls over to the next hour and keeps collecting fees until it reaches 0.1 ETH at a payout time.

How much will I get?

Your coin's share of the purse (50%, 30% or 20%) times your share of that coin's paid supply. The Odds view shows the ETH per 1M tokens if the hour closed now, and Your ticket estimates your share once you connect a wallet.

Can a creator take the fees back?

Not through KEIBA: the launch transaction makes the keeper the fee recipient, and the creator's wallet never receives the creator fee. If a coin's fee recipient ever changes, or a change is pending, the coin leaves the race.

Is there a presale?

No. Every KEIBA coin, $KEIBA included, is a fair launch on the Pons v2 bonding curve: there is no presale and no allocation minted outside the curve. The only tokens a creator gets at launch are the ones their own first buy pays for, on the same curve as everyone else.

Is $KEIBA in the race?

No. $KEIBA is the main token; it does not race and is not paid from the purse. Its supply shrinks through buyback & burn.

Which wallets are supported?

Any EVM browser wallet that can connect to Robinhood Chain (the site offers to add the network). To receive payouts you only need to hold the coin; EIP-7702 smart wallets are paid like any other.

What chain is this on?

Robinhood Chain. Coins are Pons v2 tokens paired with ETH, and payouts are in ETH.
