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 🙏

Ponder is a decentralized exchange protocol built specifically for Bitkub Chain, featuring an innovative meme token launch platform. The protocol combines Uniswap V2's proven AMM foundation with yield farming through the KOI token and a unique fair launch mechanism.

Core Protocol Components

1. Automated Market Maker (AMM)

  • Constant product formula (x * y = k)
  • 0.3% total trading fee split:
    • 0.25% to Liquidity Providers via k=xy formula
    • 0.05% protocol fee, 100% distributed to xKOI stakers
    • Special fee structure for launch tokens
  • Time-weighted price oracle system
  • Permissionless liquidity provision

2. xKOI Staking

  • Stake KOI to receive xKOI
  • 100% of protocol fees distributed via FeeDistributor contract
  • Daily automatic rebasing mechanism
  • Real yield from protocol revenue
  • Minimum first stake requirement: 1000 KOI
  • Minimum withdrawal: 0.01 KOI
  • 24-hour cooldown between reward distributions

3. Fee Distribution System

  • Dedicated FeeDistributor contract that collects, converts, and distributes fees
  • All protocol fees (0.05% of trades) are:
    • Collected and aggregated by FeeDistributor
    • Converted to KOI tokens for stakers
    • Distributed to xKOI staking contract
  • Holders of xKOI automatically receive their share of fees through rebasing
  • Fee distribution occurs at least once per day
  • Optimized batch operations for gas efficiency
  • Emergency recovery functions for contract safety

Launch Platform

The 555 Launch platform introduces a novel token launch mechanism designed to create sustainable meme token ecosystems.

Launch Creation Process

  1. Creator initiates launch with:
  • Token name and symbol
  • Token metadata (IPFS URI)
  • Initial token supply: 555,555,555 tokens
  1. Token Allocation:
  • 70% (388,888,888 tokens) - Public sale contributors
  • 20% (111,111,111 tokens) - Initial liquidity
  • 10% (55,555,555 tokens) - Creator vesting (180 days)

Launch Rules & Mechanics

  1. Target Raise:
  • Fixed at 5,555 KUB total value
  • Contributions accepted in:
    • KUB (direct)
    • KOI (valued via KOI/KUB oracle)
  • Maximum 20% of total value can be in KOI
  • Minimum contribution: 1 KUB equivalent
  • No maximum contribution per wallet
  1. Time Constraints:
  • Launch period: 7 days maximum
  • Launches complete instantly if target is met
  • All contributions refunded if target not met
  • No partial fills - must reach full 5,555 KUB value
  1. Pool Creation Upon Success:
  • KUB contributions (example: 5,000 KUB):

    • 60% (3,000 KUB) to launch token/KUB LP
    • 20% (1,000 KUB) to KOI/KUB LP
    • 20% (1,000 KUB) allocated according to the KUB_TO_MEME_PONDER_LP constant
  • KOI contributions (example: 555 KUB worth):

    • 80% to launch token/KOI LP (this is the primary source of KOI for the launch token/KOI pool)
    • 20% burned permanently
  1. LP Token Distribution:
  • All LP tokens locked for 180 days
  • Creator receives 100% of LP tokens after lock
  • No early withdrawal mechanisms
  • Lock period starts from launch completion
  1. Trading Begins:
  • Trading enabled immediately upon pool creation
  • Initial price set by pool ratios
  • Special fee structure for launch tokens:
    • KUB Pairs: 0.04% protocol, 0.01% creator
    • KOI Pairs: 0.01% protocol, 0.04% creator
    • 0.25% always to LPs

Launch Creation Rules

  1. Required Parameters:
  • Name and symbol cannot be empty
  • Name limited to 32 characters
  • Symbol limited to 8 characters
  • IPFS metadata URI required
  • Cannot use address(0) for any parameters

Launch Failure Handling

  1. Target not met within 7 days:
  • KUB Contributions: Users must manually claim refunds using claimRefund(launchId)
  • KOI Contributions: Users must manually claim refunds using claimRefund(launchId)
  • Launch remains in failed state
  • Creator receives nothing
  1. Contract-Level Restrictions:
  • Cannot start new launch if previous one exists
  • Cannot contribute after deadline
  • Cannot contribute if target already met
  • Cannot contribute with amount that would exceed target

Tokenomics

KOI Token Utility

  • LP rewards via 0.25% direct fee
  • Launch creator incentives through fees

KOI Token Distribution

    "Token Name",
    "SYMBOL",
    "ipfs://metadata"
);

// Contribute to launch
launcher.contribute(launchId);

launchToken.claimVestedTokens();

// Withdraw LP tokens (after lock period)
launcher.withdrawLP(launchId);

Farming Integration:

// Stake LP tokens
masterChef.deposit(pid, amount);

masterChef.boostStake(pid, amount);

// Harvest rewards
masterChef.deposit(pid, 0);

// Withdraw LP tokens
masterChef.withdraw(pid, amount);

Fee Distribution Integration:

// Distribute fees from specific pairs
feeDistributor.distributePairFees([pair1, pair2, ...]);

// Convert collected fees to KOI
feeDistributor.convertFees(tokenAddress);

// Trigger fee distribution to xKOI
feeDistributor.distribute();

Staking Integration:

// Stake KOI tokens for xKOI
staking.enter(amount, recipient);

// Withdraw KOI tokens (burn xKOI)
staking.leave(shareAmount);

// Claim accumulated fees without unstaking
staking.claimFees();

// Trigger reward distribution
staking.rebase();
