Launchpad Docs
Integrate Axon Fun on Robinhood Chain — launch tokens, trade the bonding curve, and route post-graduation swaps through Uniswap V3.

Guide
1. Launch a token
Call createLaunch on the launchpad. Pay at least 0.0005 ETH launch fee; any extra ETH in the same tx is an optional creator dev-buy.
// AxonLaunchpad.createLaunch
function createLaunch(
string name,
string symbol,
string metadataURI, // ipfs:// or https:// JSON
uint256 minTokensOut, // 0 if no dev-buy
bytes32 curveSalt, // CREATE2 — must end in 666
bytes32 tokenSalt // CREATE2 — must end in 666
) external payable returns (address curve, address token);
// viem / wagmi
await writeContract({
address: LAUNCHPAD_ADDRESS,
abi: launchpadAbi,
functionName: "createLaunch",
args: [name, symbol, metadataURI, 0n, curveSalt, tokenSalt],
value: parseEther("0.0005"),
});- · Metadata: launchpad.launches(launchId) or curveToLaunchId(curve)
- · Token → curve: AxonToken(token).curve()
Guide
2. Buy on bonding curve
Send ETH to buy. 2% fee (1% platform ETH + 1% creator tokens accrued on curve).
function buy(uint256 minTokensOut) external payable;
await writeContract({
address: curveAddress,
abi: bondingCurveAbi,
functionName: "buy",
args: [minTokensOut],
value: parseEther("0.1"),
});
const [tokensOut] = await readContract({
address: curveAddress,
abi: bondingCurveAbi,
functionName: "quoteBuy",
args: [parseEther("0.1")],
});Guide
3. Sell on bonding curve
Approve the curve, then call sell.
await writeContract({
address: tokenAddress,
abi: erc20Abi,
functionName: "approve",
args: [curveAddress, tokenAmount],
});
function sell(uint256 tokenAmount, uint256 minEthOut) external;
await writeContract({
address: curveAddress,
abi: bondingCurveAbi,
functionName: "sell",
args: [tokenAmount, minEthOut],
});Guide
4. Trade after graduation
When curve.graduated() is true, use AxonDexRouter for Uniswap V3 swaps (also records volume on the curve).
const DEX_ROUTER = "0xaB680aEF1aeF1724D2510E912d5120190E83111b";
function uniBuy(address curve, uint256 minTokensOut) external payable;
await writeContract({
address: DEX_ROUTER,
abi: dexRouterAbi,
functionName: "uniBuy",
args: [curveAddress, minTokensOut],
value: parseEther("0.1"),
});
// Approve DEX_ROUTER, then:
await writeContract({
address: DEX_ROUTER,
abi: dexRouterAbi,
functionName: "uniSell",
args: [curveAddress, tokenAmount, minEthOut],
});Guide
5. Read on-chain state
// BondingCurve
curve.token()
curve.creator()
curve.graduated()
curve.uniswapPool()
curve.currentPrice()
curve.tokensRemaining()
curve.ethCollected()
curve.tokensSold()
curve.graduationTarget() // 4.2 ETH
curve.claimLpFees(minWeth) // creator: 20% WETH / 80% buyback-burn
curve.claimCreatorFees(minEthOut) // creator: 80% burn / 20% ETH
// AxonToken
token.curve()Guide
6. Index trades
Pre-graduation trades emit on the curve. Launches emit on the launchpad.
event Buy(address indexed buyer, uint256 ethIn, uint256 tokensOut, uint256 newPrice);
event Sell(address indexed seller, uint256 tokensIn, uint256 ethOut, uint256 newPrice);
event DevBuy(address indexed creator, uint256 ethIn, uint256 tokensOut, uint256 newPrice);
event Graduated(address pool, uint256 ethLiquidity, uint256 tokenLiquidity, uint256 ethToDev);
event LaunchCreated(
uint256 indexed launchId,
address curve,
address token,
address creator,
string name,
string symbol
);
