Kosmo Protocol is a token launchpad on Uniswap v4. Every launch puts the whole token supply into a single-sided Uniswap v4 pool at creation, with the liquidity locked. There is no bonding curve and no capital is needed to start: the token trades on Uniswap from the first block.

Launches are live on Ethereum, Base, BNB Chain, Robinhood Chain and Ink. Each chain has its own set of contracts; nothing is shared between chains.

Robinhood Chain also carries tokens created earlier on bonding curves. They keep working exactly as before. New launches on every chain, Robinhood included, are Instant launches.

Optional, chosen by the creator at launch and fixed afterwards. They exist to slow the first minutes down so one wallet cannot take the opening supply.

When the window ends, the caps stop applying and the pool trades with no limits.

Every swap pays one fee, split three ways.

The fee splitter contract for each chain does the accounting, and the amounts are visible on-chain. The token page and the analytics page show them in dollars.

The current set is what new launches use. Earlier sets are listed under each chain: they stay deployed and their tokens keep trading.

A launch pairs the new token with ETH (or BNB on BNB Chain) or with another approved quote asset. Each chain's approved list is held by its graduation executor. To check one on-chain:

function quoteAssetConfigs(address asset) view returns (
  bool approved,
  uint256 graduationThreshold,
  uint256 virtualReserve
)

Use the zero address for the native coin. virtualReserve is the amount the pool opens against, in the asset's smallest unit. The launch page shows the pairs available on each chain.

The factory has one launch function for ordinary addresses and one that mines a vanity suffix. Both take the quote asset and a minimum for the creator's first buy.

function createLaunchDirectV3(
  string name, string symbol, uint256 tokenSupply,
  uint256 holderShareBps, uint256 burnShareBps,
  uint256 creatorBuyFeeBps, uint256 creatorSellFeeBps,
  int24 startTick, address quoteAsset, uint256 minTokensOut
) payable returns (address token, address buybackAdapter)

function createLaunchDirectV3Vanity(
  ...same arguments...,
  bytes32 salt, uint8 suffixLength, uint32 suffixValue
) payable returns (address token, address buybackAdapter)

event InstantLaunchCreated(
  address indexed token, address indexed buybackAdapter, address indexed creator,
  string name, string symbol, uint256 tokenSupply,
  uint256 holderShareBps, uint256 burnShareBps,
  uint256 creatorBuyFeeBps, uint256 creatorSellFeeBps,
  int24 startTick, address quoteAsset
)

For vanity addresses, POST /api/vanity/mine returns a CREATE2 salt and the resulting token address, which is what you need to compute startTick. Simulate the call first and check that the simulated token address matches the mined one before sending.

A complete, runnable example lives in the agent guide.

Name, symbol and supply live on-chain. The logo, description and links are saved by the site and signed by the creator's wallet, so only the launcher can change them.

Bots and autonomous agents can launch tokens the same way people do. The agent guide has the full flow as a script, and the same text is available as markdown for an agent to read directly.
