Streme Token Launcher

Deploy SuperTokens on Base via Streme's V2 contracts. Tokens include automatic Uniswap V3 liquidity, Superfluid streaming staking rewards, and optional vesting vaults.

Quick Start

import { createWalletClient, http, parseEther, encodeAbiParameters } from 'viem';
import { base } from 'viem/chains';
import { privateKeyToAccount } from 'viem/accounts';

// See references/contracts.md for full ABIs
const DEPLOYER = '0x8712F62B3A2EeBA956508e17335368272f162748';

const tokenConfig = {
  _name: 'My Token',
  _symbol: 'MYTOKEN',
  _supply: parseEther('100000000000'), // 100B
  _fee: 10000, // 10%
  _salt: '0x0...', // from generateSalt()
  _deployer: walletAddress,
  _fid: 0n, // Farcaster FID or 0
  _image: 'https://example.com/image.png',
  _castHash: 'deployment',
  _poolConfig: {
    tick: -230400,
    pairedToken: '0x4200000000000000000000000000000000000006', // WETH
    devBuyFee: 10000
  }
};

// Deploy with 10% staking (1 day lock, 365 day stream)
const stakingAlloc = createStakingAllocation(10, 1, 365);
await deployWithAllocations(tokenConfig, [stakingAlloc]);

Contract Addresses (Base Mainnet)

Deployment Flow

1. Generate Salt - Call generateSalt() to get deterministic token address
2. Upload Image - Host token image (see Image Hosting below)
3. Build Config - Create tokenConfig and allocations
4. Deploy - Call deployWithAllocations()

Image Hosting

Token images must be publicly accessible URLs. Options:

IPFS (Recommended)

// Using Pinata
const pinata = new PinataSDK({ pinataJwt: PINATA_JWT });
const { IpfsHash } = await pinata.pinFileToIPFS(fileStream);
const imageUrl = `https://gateway.pinata.cloud/ipfs/${IpfsHash}`;

Cloudinary

import { v2 as cloudinary } from 'cloudinary';

const result = await cloudinary.uploader.upload(imagePath, {
  folder: 'tokens',
  transformation: [{ width: 400, height: 400, crop: 'fill' }]
});
const imageUrl = result.secure_url;

Direct URL

Any publicly accessible image URL works:

const imageUrl = 'https://example.com/my-token.png';

Requirements

• Format: PNG, JPG, GIF, WebP
• Size: < 5MB (< 1MB recommended)
• Dimensions: Square preferred (400x400 ideal)

Upload Script

# IPFS via Pinata
PINATA_JWT=xxx npx ts-node scripts/upload-image.ts pinata ./token.png

# Cloudinary
CLOUDINARY_CLOUD_NAME=xxx CLOUDINARY_API_KEY=xxx CLOUDINARY_API_SECRET=xxx \
  npx ts-node scripts/upload-image.ts cloudinary ./token.png

# imgBB (free)
npx ts-node scripts/upload-image.ts imgbb ./token.png

Allocations

Staking Allocation (Type 1)

Streams tokens to stakers over time.

function createStakingAllocation(
  percentage: number,    // % of supply (e.g., 10)
  lockDays: number,      // min stake duration
  flowDays: number,      // reward stream duration
  delegate?: string      // optional admin address
) {
  const lockSec = lockDays * 86400;
  const flowSec = flowDays * 86400;
  
  return {
    allocationType: 1,
    admin: delegate || '0x0000000000000000000000000000000000000000',
    percentage: BigInt(percentage),
    data: encodeAbiParameters(
      [{ type: 'uint256' }, { type: 'int96' }],
      [BigInt(lockSec), BigInt(flowSec)]
    )
  };
}

Vault Allocation (Type 0)

Locked tokens with optional vesting.

function createVaultAllocation(
  percentage: number,     // % of supply
  beneficiary: string,    // recipient address
  lockDays: number,       // lockup (min 7 days)
  vestingDays: number     // vesting after lock
) {
  const lockSec = Math.max(lockDays, 7) * 86400;
  const vestSec = vestingDays * 86400;
  
  return {
    allocationType: 0,
    admin: beneficiary,
    percentage: BigInt(percentage),
    data: encodeAbiParameters(
      [{ type: 'uint256' }, { type: 'uint256' }],
      [BigInt(lockSec), BigInt(vestSec)]
    )
  };
}

Allocation Rules

• Staking + Vault percentages must be ≤100%
• Remaining % goes to Uniswap V3 LP
• Vault lock minimum: 7 days
• Standard config: 10% staking, 90% LP

Common Patterns

Standard Launch (10% staking)

const allocations = [createStakingAllocation(10, 1, 365)];

With Team Vault (10% staking + 10% vested)

const allocations = [
  createStakingAllocation(10, 1, 365),
  createVaultAllocation(10, teamAddress, 30, 365)
];

Max Liquidity (no allocations)

const allocations = [];
// 100% goes to Uniswap V3 LP
