Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

v1.6.2

Published

TypeScript SDK to deploy ERC-20 tokens with Uniswap V4 liquidity on Base — zero API keys, one dependency (viem)

Readme

Liquid Protocol SDK

TypeScript SDK for the Liquid Protocol token launcher on Base. Deploy tokens, manage pools, and claim fees using viem.

Agent Skills

The SDK ships with agent skill files — self-contained markdown guides that AI agents can load into their context to autonomously interact with Liquid Protocol on Base.

| Skill | File | What it teaches | |-------|------|-----------------| | SDK Overview | skills/sdk-overview.md | Full capabilities, data schemas (metadata, context, rewards, vault, airdrop), default config — load this first | | Deploy Token | skills/deploy-token.md | Deployment workflows — minimal deploy, dev buy, custom fees, custom positions, reward splits | | Bid in Auction | skills/bid-in-auction.md | MEV sniper auction — WETH handling, gas price encoding, block timing, automated sniper example | | Index Tokens | skills/index-tokens.md | Token discovery — bulk queries, single lookup, pagination, real-time monitoring |

Using Skills with Your Agent

# Python — load a skill into your agent's context
with open("node_modules/liquid-sdk/skills/deploy-token.md") as f:
    agent.system_prompt += f.read()
// TypeScript — read skill for an MCP server or agent framework
import { readFileSync } from "fs";
const skill = readFileSync("node_modules/liquid-sdk/skills/bid-in-auction.md", "utf-8");

For Claude Code, reference skills in your CLAUDE.md:

For token deployment, follow the instructions in node_modules/liquid-sdk/skills/deploy-token.md

Additional Agent Docs

| File | Purpose | |------|---------| | AGENT_README.md | Complete API reference with every method, type, and default (700+ lines) | | llms.txt | Compact summary for LLM context windows | | CLAUDE.md | Agent guide with architecture, defaults, and invariants |

Installation

npm install liquid-sdk viem

Defaults: Static 1% fee (both buy and sell), 5-position Liquid layout, Sniper Auction MEV (80%→40% over 20s, 5 rounds), tick spacing 200, starting tick -230400 (~10 ETH market cap). All fees converted to ETH before distribution.

Default Liquidity Positions

| # | Supply | Tick Range | Market Cap Range (@$2,000/ETH) | |---|--------|-----------|-------------------------------| | 1 | 10% | -230,400 → -216,000 | ~$20K → ~$83K | | 2 | 50% | -216,000 → -155,000 | ~$83K → ~$37M | | 3 | 15% | -202,000 → -155,000 | ~$338K → ~$37M | | 4 | 20% | -155,000 → -120,000 | ~$37M → ~$1.2B | | 5 | 5% | -141,000 → -120,000 | ~$151M → ~$1.2B |

Quick Start

import { createWalletClient, http } from "viem";
import { privateKeyToAccount } from "viem/accounts";
import { base } from "viem/chains";
import { LiquidSDK } from "liquid-sdk";

const account = privateKeyToAccount(process.env.PRIVATE_KEY as `0x${string}`);

const walletClient = createWalletClient({
  account,
  chain: base,
  transport: http(),
});

const liquid = new LiquidSDK({ walletClient });

Deploy a Token

const result = await liquid.deployToken({
  name: "My Token",
  symbol: "MTK",
  image: "ipfs://QmYourImageHash",
  metadata: '{"description": "My token description"}',
});

console.log("Token deployed at:", result.tokenAddress);
console.log("Pool ID:", result.event.poolId);
console.log("Tx:", result.txHash);

Deploy with Custom Market Cap Positions

import { createDefaultPositions, createPositionsUSD } from "liquid-sdk";

// Use default 3-tranche split ($500K / $10M / $1B) at current ETH price
const positions = createDefaultPositions(20_000, 2070); // $20K start, $2070/ETH

const result = await liquid.deployToken({
  name: "My Token",
  symbol: "MTK",
  ...positions, // tickLower, tickUpper, positionBps, tickIfToken0IsLiquid
});

// Or define fully custom tranches
const custom = createPositionsUSD(50_000, 2070, [
  { upperMarketCapUSD: 1_000_000, supplyPct: 30 },
  { upperMarketCapUSD: 50_000_000, supplyPct: 50 },
  { upperMarketCapUSD: 500_000_000, supplyPct: 20 },
]);

Deploy with Custom Fees

import { ADDRESSES, encodeStaticFeePoolData, encodeDynamicFeePoolData } from "liquid-sdk";

// Static 2% fee
const result = await liquid.deployToken({
  name: "Custom Fee Token",
  symbol: "CFT",
  poolData: encodeStaticFeePoolData(200, 200), // 2% both directions
});

// Dynamic fee (1%-5% range)
const result2 = await liquid.deployToken({
  name: "Dynamic Token",
  symbol: "DYN",
  hook: ADDRESSES.HOOK_DYNAMIC_FEE_V2,
  poolData: encodeDynamicFeePoolData({
    baseFeeBps: 100,
    maxFeeBps: 500,
    referenceTickFilterPeriod: 30,
    resetPeriod: 120,
    resetTickFilter: 200,
    feeControlNumerator: 500000000n,
    decayFilterBps: 7500,
  }),
});

Sniper Auction (MEV Bidding)

Bid for early access to newly launched tokens. The SDK handles WETH wrapping, approvals, gas price encoding, and timing automatically.

import { LiquidSDK, EXTERNAL } from "liquid-sdk";

// 1. Get auction state & pool key
const auction = await liquid.getAuctionState(poolId);
const rewards = await liquid.getTokenRewards(tokenAddress);
const zeroForOne = rewards.poolKey.currency0.toLowerCase() === EXTERNAL.WETH.toLowerCase();

// 2. Calculate gas price for your bid
const gasPrice = await liquid.getAuctionGasPriceForBid(auction.gasPeg, parseEther("0.001"));

// 3. Wait for auction block, then fire
const result = await liquid.bidInAuction({
  poolKey: rewards.poolKey,
  zeroForOne,
  amountIn: parseEther("0.001"),     // WETH to swap (auto-wrapped)
  amountOutMinimum: 0n,
  round: auction.round,
  bidAmount: parseEther("0.0005"),   // ETH bid (msg.value)
}, gasPrice);

Token Discovery

// Get all tokens
const allTokens = await liquid.getTokens();

// Get tokens by deployer
const myTokens = await liquid.getTokens({ deployer: myAddress });

// Look up a single token (fast, indexed)
const token = await liquid.getTokenEvent(tokenAddress);

// Paginate with block ranges
const page = await liquid.getTokens({ fromBlock: 20000000n, toBlock: 20100000n });

Read Token Info

const info = await liquid.getTokenInfo(tokenAddress);
console.log(info.name, info.symbol, info.decimals);
console.log("Hook:", info.deployment.hook);
console.log("Locker:", info.deployment.locker);

Claim Fees & Rewards

// LP Rewards
const rewards = await liquid.getTokenRewards(tokenAddress);
await liquid.collectRewards(tokenAddress);

// Fee claims (all fees converted to ETH by default)
const claimable = await liquid.getFeesToClaim(ownerAddress, tokenAddress);
await liquid.claimFees(ownerAddress, tokenAddress);

Vault (Token Vesting)

const allocation = await liquid.getVaultAllocation(tokenAddress);
const claimable = await liquid.getVaultClaimable(tokenAddress);
await liquid.claimVault(tokenAddress);

Constants & ABIs

All production addresses, fee parameters, and contract ABIs are exported:

import {
  ADDRESSES,        // Liquid Protocol contract addresses
  EXTERNAL,         // External protocol addresses (PoolManager, WETH, etc.)
