# Flaunch — Direct Mode Reference

Launch tokens on Base with bonding curves, fair launch periods, and custom fee split managers. Fine-grained control over fee distribution through deployed manager contracts.

## Setup

```bash
npm install viem
```

```typescript
import {
  createPublicClient,
  createWalletClient,
  http,
  encodeFunctionData,
  encodeAbiParameters,
  formatEther,
} from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";

// Load securely from secrets manager — never hardcode
const account = privateKeyToAccount(process.env.LAUNCH_WALLET_PRIVATE_KEY as `0x${string}`);
```

> **Security:** Use a dedicated launch wallet funded with minimal ETH for gas. The private key should be loaded from a secrets manager, not from plaintext config. See the [Security section in REFERENCE.md](../REFERENCE.md) for details.

You'll also need the Flaunch contract ABIs:
- `FlaunchZap` — the main launch contract
- `TreasuryManagerFactory` — deploys custom fee managers
- `AddressFeeSplitManager` — the fee distribution contract

These are available from the Flaunch docs or by reading the verified contracts on Basescan.

## Architecture

Flaunch uses a modular architecture for fee management:

```
Token Launch (FlaunchZap.flaunch())
├── Creates ERC-20 token
├── Sets up bonding curve / Uniswap pool
└── Attaches a Treasury Manager
    └── AddressFeeSplitManager (custom, deployed by you)
        ├── Recipient 1: your_wallet (100%)
        └── (or multiple recipients with custom splits)
```

The key insight: the fee manager is a **separate deployed contract** that you create before launching the token. This gives you full control over fee distribution without the token contract itself needing custom logic.

---

## Contract Addresses (Base Mainnet)

These are configured as environment variables in your runtime:

```
FLAUNCH_ZAP_CONTRACT_ADDRESS_BASE=<address>
TREASURY_MANAGER_FACTORY_ADDRESS_BASE=<address>
ADDRESS_FEE_SPLIT_MANAGER_IMPLEMENTATION_BASE=<address>
```

Check the Flaunch docs for the latest deployed addresses.

## Launch a Token

### Step 1: Create a Custom Fee Split Manager

```typescript
// Define your fee split — 100% to yourself
const recipientShares = [
  {
    recipient: YOUR_WALLET_ADDRESS,
    share: BigInt(100_00000), // 100% in Flaunch basis points (share * 100000)
  },
];

// Encode initialization params
const initializeParams = encodeAbiParameters(
  [
    {
      type: "tuple",
      components: [
        { name: "creatorShare", type: "uint256" },
        {
          name: "recipientShares",
          type: "tuple[]",
          components: [
            { name: "recipient", type: "address" },
            { name: "share", type: "uint256" },
          ],
        },
      ],
    },
  ],
  [
    {
      creatorShare: BigInt(0), // All goes to recipients
      recipientShares: recipientShares,
    },
  ]
);

// Deploy the manager
const managerTxHash = await walletClient.writeContract({
  address: TREASURY_MANAGER_FACTORY_ADDRESS,
  abi: treasuryManagerFactoryAbi,
  functionName: "deployAndInitializeManager",
  args: [
    FEE_SPLIT_MANAGER_IMPLEMENTATION, // Implementation address
    OWNER_ADDRESS,                     // Manager owner
    initializeParams,
  ],
});

const receipt = await publicClient.waitForTransactionReceipt({
  hash: managerTxHash,
});

// Extract the deployed manager address from the receipt logs
const customManagerAddress = getDeployedManagerAddress(receipt.logs);
```

### Step 2: Launch the Token

```typescript
const flaunchParams = {
  name: "Galaxy Cat",
  symbol: "GCAT",
  tokenUri: IPFS_METADATA_URI,          // Upload metadata to IPFS first
  initialTokenFairLaunch: BigInt("60000000000000000000000000000"), // 60% of supply
  fairLaunchDuration: BigInt(30 * 60),   // 30 minute fair launch
  premineAmount: BigInt(0),
  creator: YOUR_WALLET_ADDRESS,
  creatorFeeAllocation: 100 * 100,       // 100% managed by the fee split manager
  flaunchAt: BigInt(0),                  // Launch immediately
  initialPriceParams: DEFAULT_INITIAL_PRICE_PARAMS,
  feeCalculatorParams: "0x",
};

const whitelistParams = {
  merkleRoot: "0x" + "0".repeat(64),
  merkleIPFSHash: "",
  maxTokens: BigInt(0),
};

const airdropParams = {
  airdropIndex: BigInt(0),
  airdropAmount: BigInt(0),
  airdropEndTime: BigInt(0),
  merkleRoot: "0x" + "0".repeat(64),
  merkleIPFSHash: "",
};

const treasuryManagerParams = {
  manager: customManagerAddress,   // Your deployed fee split manager
  initializeData: "0x",
  depositData: "0x",
};

const hash = await walletClient.writeContract({
  address: FLAUNCH_ZAP_ADDRESS,
  abi: flaunchZapAbi,
  functionName: "flaunch",
  args: [flaunchParams, whitelistParams, airdropParams, treasuryManagerParams],
});

const receipt = await publicClient.waitForTransactionReceipt({ hash });
const tokenAddress = getMemecoinAddress(receipt.logs, "standard");
```

### Multiple Recipients (e.g., 70/30 Split)

```typescript
const recipientShares = [
  {
    recipient: CREATOR_WALLET,
    share: BigInt(70_00000), // 70%
  },
  {
    recipient: TREASURY_WALLET,
    share: BigInt(30_00000), // 30%
  },
];
```

Shares must total `100_00000` (100%).

## Check Unclaimed Fees

Call `balances(recipientAddress)` on the fee split manager contract:

```typescript
const feeManagerAbi = [
  {
    inputs: [{ name: "_recipient", type: "address" }],
    name: "balances",
    outputs: [{ name: "balance_", type: "uint256" }],
    stateMutability: "view",
    type: "function",
  },
];

const balance = await publicClient.readContract({
  address: FEE_MANAGER_ADDRESS,
  abi: feeManagerAbi,
  functionName: "balances",
  args: [YOUR_WALLET_ADDRESS],
});

const balanceEth = parseFloat(formatEther(balance));
console.log(`Unclaimed fees: ${balanceEth} ETH`);
```

---

## Claim Fees

Call `claim()` on the fee split manager. The caller receives their share:

```typescript
const claimAbi = [
  {
    inputs: [],
    name: "claim",
    outputs: [{ name: "", type: "uint256" }],
    stateMutability: "nonpayable",
    type: "function",
  },
];

// Direct execution
const hash = await walletClient.writeContract({
  address: FEE_MANAGER_ADDRESS,
  abi: claimAbi,
  functionName: "claim",
});

// Or build unsigned transaction for external wallets
const data = encodeFunctionData({
  abi: claimAbi,
  functionName: "claim",
});

const unsignedTx = {
  to: FEE_MANAGER_ADDRESS,
  data: data,
  value: "0",
  gas: "200000",
};
```

---

## Transfer Fee Recipient (Update Who Gets Paid)

Call `transferRecipientShare(newRecipient)` on the fee manager. Must be called by the current recipient.

**Important:** Claim any accumulated fees before transferring — unclaimed fees belong to the current recipient and may not be claimable after transfer.

```typescript
const transferAbi = [
  {
    inputs: [{ name: "_newRecipient", type: "address" }],
    name: "transferRecipientShare",
    outputs: [],
    stateMutability: "nonpayable",
    type: "function",
  },
];

// Step 1: Claim existing fees first
await walletClient.writeContract({
  address: FEE_MANAGER_ADDRESS,
  abi: claimAbi,
  functionName: "claim",
});

// Step 2: Transfer the share to the new recipient
await walletClient.writeContract({
  address: FEE_MANAGER_ADDRESS,
  abi: transferAbi,
  functionName: "transferRecipientShare",
  args: [NEW_RECIPIENT_ADDRESS],
});
```

### Unsigned Transaction Version

```typescript
const data = encodeFunctionData({
  abi: transferAbi,
  functionName: "transferRecipientShare",
  args: [NEW_RECIPIENT_ADDRESS],
});

const unsignedTx = {
  to: FEE_MANAGER_ADDRESS,
  data: data,
  value: "0",
  gas: "200000",
};
```

---

## Gas Estimation

Flaunch operations can vary in gas cost. Always estimate with a buffer:

```typescript
let gas;
try {
  const estimate = await publicClient.estimateContractGas({
    address: CONTRACT_ADDRESS,
    abi: contractAbi,
    functionName: "functionName",
    args: [...],
    account: YOUR_ADDRESS,
  });
  gas = (estimate * 150n) / 100n; // 50% buffer
} catch (e) {
  gas = BigInt(200000); // Fallback default
}
```

---

## Key Constants

```typescript
// Default token supply: 100 billion (60% in fair launch)
const DEFAULT_INITIAL_SUPPLY = BigInt("60000000000000000000000000000");

// Default fair launch: 30 minutes
const DEFAULT_FAIR_LAUNCH_DURATION = BigInt(30 * 60);

// Fee split basis points: share * 100000
// 100% = 100_00000
// 90%  = 90_00000
// 10%  = 10_00000
```

---

## Important Notes

- Flaunch is currently **Base only**
- The fee split manager is a separate deployed contract — you need to track its address alongside the token address
- Only the **current recipient** can call `transferRecipientShare` — unlike Clanker where the admin can update
- `claim()` can be called by anyone but only pays out to the registered recipients
- Fair launch duration prevents sniping by design — all purchases during the fair launch period get the same price
