rdog is a memecoin launchpad on Robinhood Chain, built on a real Uniswap V4 pool. All taxation happens in a single shared Uniswap V4 hook (RdogTaxHook), which taxes every swap in the pool's afterSwap callback — no matter which router, aggregator or UI sent it. Anyone can launch a coin in one transaction — no presale, no team allocation, no manual liquidity seeding. The whole supply is locked as single-sided liquidity at launch, so your coin opens at roughly a $3,000 market cap with zero capital and is tradeable from block one. There is no graduation and no migration — liquidity lives in V4 forever.

Every launched coin has the same fixed supply. No team allocation, no vesting, no presale. At launch the token's owner authority is renounced to the black hole (0x000…dEaD) in the same transaction, so the supply can never grow — there is no mint function at all. 100% is locked as V4 liquidity (permanently, no remove path) at launch.

Pricing uses a real Uniswap V4 concentrated position seeded at the top of the range, so the ETH reserve starts at 0 and the whole supply sits on the token side. The opening market cap is set by the initial tick (a constant-product curve with a virtual ETH reserve of L / sqrt(P_upper)), not by fake reserves.

A single wallet can never hold more than 2% of total supply. This is permanent and hardcoded in the token — there is no admin key to change it.

You choose the buy tax and the sell tax at launch, from 0% to 8%. The tax is taken by RdogTaxHook from the swap's output, so it applies to every trade in the pool — including trades routed through Uniswap, 1inch or any aggregator. A flat 0.1% platform fee on the trade amount is charged on pool legs on top of the tax. Once the coin is live the config is locked forever (the contract renounces itself in the launch transaction).

Every launch gets its own on-chain vault. Nothing is custodied off-chain and nothing sits in a wallet: the vault holds the buyback ETH, and it is the only thing that can liquidate tax tokens. Buy tax and sell tax fund two different purposes — 100% of the sell tax accrues to holders as ETH, while the whole buy tax accumulates as ETH earmarked for buying the coin back and burning it.

Buy: fewer coins, no dump. The buy tax never becomes tokens, so it is never sold back into the pool. A buy therefore costs zero tax-dump and zero extra slippage — you just receive less of the coin, and the difference waits in the vault as real buying power.

Real buyback, then burn. The coin's dev or the platform wallet spends the vault's buyback ETH on an actual market purchase, and the coins it bought are destroyed. It is capped at 20% of the reserve per call, one call per block, and the previous batch must be burned before the next one — so nobody can chain buybacks to pump the price. Minimum output is computed on-chain from the live pool price; the caller cannot supply it.

ETH dividends. The sell tax is converted to ETH in the same transaction as the sale and pushed back into the coin via fundDividend() — accrued straight to every holder on-chain, pro-rata over circulating supply. Holders call claim() and receive ETH — never the launched coin.

2% per wallet, and you can always sell. The cap is checked on the receiver only, so if buyback burns shrink the supply and your balance drifts above the cap, you can still sell — selling goes wallet → pool and the pool is exempt from the check. You just cannot buy more until you are back under it.

There is no creator fee. Launching earns nothing automatically — if you want exposure, buy your own coin on the open market like everyone else.

No graduation, no migration. Coins are ranked by market cap and the badge updates on-chain the moment a threshold is crossed.

The launch router and the tax hook are the only shared contracts; each launch deploys its own tax token atomically into a fresh V4 pool whose PoolKey carries the hook, and registers it so afterSwap taxes that pool. Every contract is open source — click an address to view its verified Solidity on Blockscout (the #code tab), or open the source viewer on any token page.

Source transparency. The token contract (RdogTaxToken) is a plain ERC-20 — pool legs are not taxed at the token level, because RdogTaxHook does the taxing inside the pool for every router. Each coin's RdogTaxVault holds the buyback ETH, forwards dividends and runs the buyback & burn. Every launch is verified open-source on the block explorer automatically: the site reads the constructor arguments back off the chain and submits the flattened source, and the explorer compares it against the deployed bytecode. You can also re-trigger it from the Verify source button on any token page, and read every contract in-app via the </> source button — without trusting the explorer at all.

We publish exactly what the platform can and cannot do, so you can verify it on-chain rather than take our word for it.

Trade taxes and dividends are collected and distributed entirely on-chain. The token contract itself has no function that can move a holder's balance or the pool's liquidity. Social links shown on a coin page must be signed by the wallet that launched the coin — nobody can attach a fake Telegram or X link to someone else's coin.
