Clanker v4 is Here to Change the Game for Meme Coin Liquidity

Get ready, creators and traders! Clanker v4 is set to shake things up, fundamentally changing how we think about liquid markets, especially in the fast-paced world of meme coins. This major upgrade introduces a suite of powerful new features designed to give builders more control, flexibility, and tools to launch and manage their tokens.

Here's a breakdown of what Clanker v4 brings to the table:

What's New in Clanker v4? Key Features at a Glance

Clanker v4 is packed with innovations aimed at empowering token teams and improving market dynamics. Some of the standout features include:

• Customizable Fee Structures: Fine-tune trading fees like never before.
• Custom Liquidity Distributions: Shape your token's price curve with multiple liquidity positions.
• Multiple Reward Recipients: Distribute trading fee rewards to several addresses.
• Streamlined Rewards: Claim WETH rewards for multiple tokens in one go.
• MEV Modules: Combat front-running and sniping from the get-go.
• Clanker Extensions: Add advanced functionality like token vaulting and streamlined creator buys.

Let's dive into some of these features in more detail.

Flexible Fee Structures: Static or Dynamic Control

Clanker v4 gives token creators unprecedented control over trading fees within their liquidity pools. Fees can be set up in two main ways:

Static Fees

With static fees, you can configure fixed percentage fees for swaps on a per-token basis. This means you can set different fee percentages depending on which token is being swapped. For instance:

• Swapping the Clanker token for its paired token incurs a 1% fee.
• Swapping the paired token for the Clanker token incurs a 2% fee.

This offers simple, predictable fee collection, fully customizable via the SDK.

Dynamic Fees

For those seeking more sophisticated fee management, dynamic fees adjust based on market activity. A base static fee is always collected, but a variable fee is added on top. This variable fee is calculated based on factors like the price impact of the current swap and how volatile the token's price has been recently.

Essentially, if a token's price is moving rapidly, the effective trading fee will be higher. Dynamic fees collect both the Clanker token and the paired token as fees. Full customization is available via the SDK, with more technical details coming soon.

Clanker Protocol Fee

It's worth noting that the Clanker protocol itself now collects a small fee at the pool level. This fee is 20% of the effective trading fee (static + dynamic), and it applies to liquidity providers beyond the initial pool creator.

Advanced Liquidity Control: Shape Your Price Curve

Gone are the days of simply placing all liquidity in one wide range. Clanker v4 allows creators to add up to 7 different LP (Liquidity Provider) positions when setting up the initial pool.

Instead of liquidity being spread evenly from the starting price to infinity, you can now concentrate liquidity in specific price ranges. This lets token creators design a custom liquidity profile, making more or fewer tokens available at different price points depending on their strategy. This feature is accessible via the SDK.

Empowering Creator Rewards

Token creators earn rewards from the trading fees generated in the initial liquidity pool they set up. Clanker v4 makes the distribution of these rewards more flexible.

You must set at least one pair of a rewardAdmin (who manages the recipient) and a rewardRecipient (who receives the fees). You can include up to 7 such pairs.

For each pair, you define the percentage of trading fees the rewardRecipient gets using rewardBps. rewardBps is in basis points (where 1 basis point = 0.01%). The total of all rewardBps across all recipient pairs must add up to 10,000 (or 100%).

What can be changed?

• A rewardAdmin can change the specific address of their paired rewardRecipient.

What cannot be changed?

• A rewardAdmin cannot change a rewardRecipient they are not paired with.
• The rewardBps percentages, once set, cannot be changed after the token is deployed.

Streamlined Reward Claiming

Claiming your earned trading fees is now simpler. Clanker's backend contracts automatically gather fees from LP positions and send them to a dedicated locker. The claiming process is now done on a per-token basis. This means recipients can claim their WETH rewards for multiple tokens they've created in a single transaction, instead of having to claim separately for each token pair.

Fighting MEV Snipers with MEV Modules

MEV (Maximal Extractable Value) can be a big challenge for new token launches, with bots "sniping" buys right at deployment. Clanker v4 introduces MEV modules to help combat this.

The initial module offers a 2-block delay between when a token/pool is deployed and when trading actually becomes active. This built-in pause helps prevent bots from front-running the very first trades. This is just the first step in Clanker's anti-sniper technology, with more developments planned.

Powerful Extensions: Vaulting, Creator Buys, and Airdrops

Clanker Extensions group together powerful functionalities that can be added during the token deployment process. Up to 90% of the total token supply can be allocated to these extensions combined.

Vaulting

Vaulting lets token creators set aside a portion of the token supply before it's added to liquidity. Up to 90% of the supply can be vaulted. This can be used for team tokens, future ecosystem funds, or other locked allocations.

Key aspects of Vaulting:

• Lockup Duration: The minimum time after token creation before vesting starts. The enforced minimum lockup is 7 days.
• Vesting Duration: The period during which tokens become available linearly after the lockup ends. Tokens vest smoothly over this time, not all at once at the end.
• Admin: An address that can claim available tokens after the lockup ends and during the vesting period. The amount claimable depends on how much time has passed since the lockup ended and how many tokens have already been claimed. The claim function is public, meaning anyone can trigger the claim process for the designated recipient address.
• Changing Admin: The current admin address can change the admin address for the vaulted tokens, allowing for transfer of control (e.g., from a founder's wallet to a team multisig).
• Cannot Be Changed: The lockupDuration and vestingDuration cannot be changed after deployment.

Creator Buy / Dev Buy

The Creator Buy (often called Dev Buy) function allows the token creator to use any amount of ETH to make an initial purchase of their token right after the pool is created. This functionality remains the same.

However, there's an update for tokens not paired directly with WETH: the paired token must now have an existing WETH <> Paired Token Uniswap v4 pool in order for the Dev Buy to successfully complete.

Airdrops (Coming Soon)

A highly anticipated feature! Clanker v4 will soon support setting up airdrop allocations with vesting parameters directly upon token creation. Tokens will be allocated to specified recipients and become claimable after a minimum lockup duration of one day. Once available, anyone will be able to initiate the claim process for a given airdrop recipient. Contract support is live, with the user-friendly frontend and SDK support coming soon.

Clanker v4 represents a significant leap forward in providing sophisticated tools for meme coin launches and liquidity management. The added flexibility in fees, liquidity, rewards, and the introduction of anti-MEV measures and extensions like vaulting aim to empower creators and foster healthier token ecosystems.
