/ Overview

HoldFlow is a token launchpad on Robinhood Chain built around one rule: the trading fees of every token go to the holders of all the other tokens. Hold any token on the board and every other pool on it works for you. The fees of the token you hold go to everyone else.

Anyone can launch a token. It trades against ETH in a plain Uniswap v4 pool from the first block, so wallets, routers and trading terminals see it right away. There is no separate bonding-curve contract, no migration and no liquidity anyone could pull: the whole supply of the token sits in one permanent position that prices like a curve.

Chain

Robinhood Chain (4663), Arbitrum Orbit

Pair

ETH, Uniswap v4, no hooks

Token supply

1,000,000,000, no owner, no mint, no tax

Start

≈ 2.02 ETH market cap, then up the curve in the same pool

Pool fee

1% fixed, 100% to the fee wallet for holders

Launch fee

0.0005 ETH

/ Official token

• The contract address is published on this page. Check the address, not the name.
• Pons lives at ponsfamily.com.
• Nobody from the team will message you a contract address or ask you to send funds.
• A token on our board that uses $FLOW or “HoldFlow” as its ticker or name is marked as not official, and the launch form refuses those names.

/ Holder rewards

Every trade on the board pays a 1% pool fee. The fee of each token is collected to the fee wallet and split between the holders of the other tokens. Nothing returns to the holders of the token that generated it, so trading your own token in circles pays everyone except you.

What counts

• Your share of a token’s supply. The balance in your wallet is what counts: there is nothing to stake or lock.
• The ETH sitting in that token’s pool. A token with real money behind it weighs more than an empty one, so launching a dead token to farm the others does not work.
• How long you have held. The clock starts with your first buy and resets when tokens leave your wallet.
• The pool, the factory and the burn address are not holders.

Epochs

Fees are swept from the pools and distributed epoch by epoch, in ETH. The first epoch has not been settled yet: the epoch length, the smallest balance that counts and the exact weights are published on this page before it is.

/ Launching a token

1. 1Choose a name, a ticker of 2 to 10 letters or digits and an image. A website, an X account, Telegram and a description are optional. Everything is written once and cannot be edited.
2. 2Optionally add a dev buy. It is made inside the launch transaction, so it is the only buy that is certain to come first, and the tokens go straight to your wallet. There is no other allocation for the creator.
3. 3Sign one transaction and pay 0.0005 ETH plus your dev buy. The factory deploys the token, opens the pool and places the whole supply in it.

You do not provide liquidity. The token’s own supply is the liquidity, and it stays in the factory’s position forever. The creator receives no fees from the token.

/ The pool and its curve

The curve is not a separate contract. It is one single-sided Uniswap v4 position that holds all 1,000,000,000 tokens, from the start price up to the highest price the pool allows. Buys walk the price up and leave ETH in the position, sells walk it back down and take ETH out. Starting with no ETH in it, the position prices exactly like a constant-product curve with 2.02 ETH of virtual reserves.

Start price

≈ 494.5M tokens per ETH

Start market cap

≈ 2.02 ETH

Position

ticks −887,200 to 200,200, spacing 200

Migration

None. One pool id for the life of the token

Liquidity removal

No function exists in the factory

Dust

Rounding leftovers are burned at launch

How far the price goes

The pool holds no ETH below the start price, so a sell cannot push the price under it. A sell that would go lower fills partially: only the tokens the pool can pay for leave your wallet.

/ Fees

Token pool fee

1% of every buy and sell, fixed in the contract

Who receives it

The fee wallet, for holder rewards. 100%

Creator share

0%

Launch fee

0.0005 ETH, the fee wallet may change it, never above 0.01 ETH

Fees accrue inside the factory’s position. Buys pay in ETH, sells pay in the token. collectFees(token) is permissionless: anyone can call it, and everything it collects goes to the fee wallet. The wallet can pass its role on only from its own address, in two steps, so a mistyped address cannot take it over.

The pool is an ordinary Uniswap pool, so anyone may add liquidity of their own to it. That liquidity earns its share of the 1% inside its range, like anywhere on Uniswap.

/ Trading and terminals

• On this site: one transaction from ETH through the factory. The quote is a simulation of the same swap, so the fill equals the quote while the pool does not move, with a 1% slippage guard if it does.
• Anywhere else: any Uniswap v4 router. The pool key is ETH (the zero address) and the token, fee 10000, tick spacing 200, no hooks. The pool id is on every token page.
• Terminals that index Uniswap v4 on Robinhood Chain, GMGN among them, pick a pool up from its first block. Paste the contract address from the token page.

A round trip costs two 1% pool fees plus the price impact of your own size.

/ Risks

• Tokens launched here are memecoins. Their price can go to zero, and rewards do not protect against that.
• Rewards depend on trading volume. A quiet board pays little.
• The split between holders is run by the team off-chain from the fee wallet. It is transparent, it is not trustless.
• There is no sniper protection. The dev buy inside the launch transaction is the only buy certain to be first.
• Smart contracts can have bugs. The factory is tested against the live PoolManager; it has not been audited.
• Robinhood Chain has one sequencer. If it stops, trading stops.
