Check Token ($CHECK) Launches on Uniswap

Introduction

Token launches are a pivotal moment in the blockchain space. They represent the birth of new ecosystems, financial models, and innovations that push the industry forward. Every successful operation starts with a launch that brings in liquidity, adoption, and an active community.

Today we celebrate an important milestone with the official launch of Check Token ($CHECK) on Uniswap. Designed to bridge the gap between NFTs and on-chain finance, Check Token introduces real financial utility to NFTs, creating new and innovative opportunities for decentralized payments, vesting schedules and yield-generating mechanisms, strategic governance for native token holders, and much more.

As trading begins and adoption grows, the utility of Check Token will continue to evolve in tandem, and will stand as a testament to how NFT technology can merge seamlessly with on-chain finance, offering avenues for structured, verifiable, and secure financial interactions — all while maintaining the decentralized ethos that makes crypto so powerful.

Check Token Launched

Check Token ($CHECK) has officially launched on Uniswap today, May 18th, 2025. Traders can now exchange $POL for $CHECK, or vice versa by accessing the Uniswap trading interface.

With the Uniswap launch now complete, the token is poised to expand its market presence. In the coming weeks, $CHECK will be listed on LBank, introducing a $USDT trading pair that will enhance liquidity and provide additional trading options for token holders. This listing will further solidify Check Token’s position in the crypto markets, offering users more flexibility and access to a broader range of trading opportunities.

The Paycheck Labs team is committed to fostering trust, upholding transparency, and pursuing ongoing innovation. In the months ahead, the team will be rolling out multiple utility centric features, expanding opportunities, and forming strategic partnerships to strengthen and grow the project ecosystem.

We encourage community members to join our official channels and stay engaged with project updates, as this launch marks just the beginning of our flagship token’s mission to transform the landscape where NFTs and digital finance converge.

Lockup Note: Liquidity locking and token distribution locking will occur some time after the initial launch. This approach allows us to monitor price spreads and ranges to maximize capital efficiency and ensure the most attractive incentives for liquidity providers. Once we have fine-tuned our strategy and optimized the parameters, we will proceed with lockups.

Tracking Note: Our team is actively submitting requests to have the token logo displayed on Polygonscan and supported wallets. Although the logo may not appear immediately at launch, it will be visible soon once these updates are processed and finalized.

Token Audit

The Check Token contract was audited by Hacken, with zero vulnerabilities found — highlighting our ultimate commitment to security and best industry practices.

The contract utilizes OpenZeppelin libraries for its ERC-20 implementation, ensuring reliable, industry-standard, and thoroughly tested code. By building on these trusted frameworks and undergoing a comprehensive audit by a leading Web3 security firm, the contract significantly reduces risk and upholds the highest standards of smart contract security and best practices.

Security Measures

Multiple layers of security have been implemented to ensure the safety, transparency, and integrity of the Check Token:

Immutable Smart Contract

The Check Token contract is fully immutable. It includes no minting functions, no hidden backdoors, and no administrative override capabilities. This ensures a fixed maximum supply of 100 billion tokens, creating long-term certainty and eliminating inflationary risk.

Verified on Polygonscan

The contract code is publicly verified and published on Polygonscan, allowing any user or developer to audit it transparently. Full visibility of the code and transactions reinforces community trust.

Multisig Treasury Control

Treasury funds are managed through multisignature wallets, requiring approval from multiple trusted parties before any transaction can occur. This prevents unilateral access and reduces the risk of internal compromise or unauthorized transfers.

No Upgradeable Proxy

The token contract does not use an upgradeable proxy pattern. The absence of upgradability ensures that the contract’s audited logic is locked and cannot be changed in the future, reducing risk for exploits and possible governance attack vectors.

To reinforce our ongoing commitment to security, additional independent audits are planned for the future, ensuring maximum protection for token holders.

Token Utility

Check Token is not a speculative asset without purpose — it’s a foundational utility token that will power the Checks Platform currently in development, unlocking real decentralized finance use cases that make a difference.

Yield Checks

The Checks Platform introduces an innovative staking feature known as Platform Yield, powered exclusively by the $CHECK token. Users mint Yield Checks by locking the platform’s native token into this special NFT Check type. Locking tokens establish the user’s staked position.

Staking & Rewards

Users are incentivized to stake CHECK tokens by minting Yield Checks, earning a generous share of up to 25% in platform fees and revenue generated by the platform.

Rewards are distributed in major currencies, such as:

• Stablecoins (USDC, USDT, DAI)

• Blue-chip assets (POL, ETH, BNB)

The distribution depends on platform activity and revenue sources. This model, similar to liquidity mining, encourages long-term staking, fostering user commitment while enhancing the platform’s security and sustainable growth.

Governance

Check Token is the utility and governance token at the heart of the Checks Platform. It is implemented on Polygon for fast and low-cost transactions, and serves several key functions in the ecosystem.

• Protocol upgrades

• Fee parameters

• Adding new features and supported chains

• Strategic initiatives

The Checks DAO, introduced as a post-MVP feature, ensures that the platform evolves through stakeholder consensus. Much like governance models used by protocols such as AAVE and Compound, token holders will have a direct voice in shaping the future direction of the platform.

How to Add $CHECK to MetaMask

Adding $CHECK to MetaMask ensures you can view and manage your tokens directly within your wallet.

Migration Tip: If you previously held the old $CHECK token before the migration, we strongly recommend removing it from your MetaMask wallet before adding the new one. This will help prevent confusion and ensures you only interact with the new upgraded token.

Follow these steps to add $CHECK on the Polygon network:

1. Ensure Polygon Network is Added

First, make sure your MetaMask wallet is set to the Polygon network. If you haven’t added Polygon yet:

Open MetaMask and click the network dropdown at the top.

• Select “Add Network” and enter the following details:

• Network Name: Polygon

• RPC URL: https://polygon-rpc.com

• Chain ID: 137

• Currency Symbol: POL

• Block Explorer URL: https://polygonscan.com/

• Click “Save” to add Polygon to your networks

2. Add $CHECK as a Custom Token

In MetaMask, make sure you’re on the Polygon network.

• Scroll down and click “Import Tokens”

• Select the “Custom Token” tab

• Paste the $CHECK contract address:

• 0x5714B76B3D69f797BeDe08409e027e1a280C2530

• MetaMask should automatically fill in the Token Symbol ($CHECK) and Decimals.

• Click “Add Custom Token,” then “Import Tokens” to complete the process

3. View Your $CHECK Balance

After importing, $CHECK will appear in your wallet under the assets tab. If you receive $CHECK in your wallet, your balance will update automatically.

Security Tip: Always verify website URLs carefully before visiting to avoid phishing sites, and double-check token contract addresses before adding custom tokens to your wallet to protect yourself from scams and counterfeit tokens.

Adding $CHECK to MetaMask is quick and ensures you can monitor, send, and receive your tokens seamlessly on Polygon.

How to Buy $CHECK on Uniswap

Below is a simple, step-by-step guide to help you buy $CHECK on Uniswap quickly and securely. Whether you’re new to decentralized exchanges or an experienced trader, these instructions will walk you through the entire process.

1. Connect Your Wallet

Visit the Uniswap web app and connect your Web3 wallet, such as MetaMask, Trust Wallet, or Phantom. Make sure your wallet is set to the Polygon network, since $CHECK is a Polygon token.

2. Select the $CHECK Trading Pair

In the Uniswap interface, click the token selection dropdown. To ensure you’re trading the correct token, paste the official $CHECK contract address. Select Check Token ($CHECK) as the token you want to buy, and Polygon ($POL) as the coin you want to swap from.

3. Enter the Amount

Enter the amount of $POL you want to swap for $CHECK, or the amount of $CHECK you want to receive. You can set a custom amount or use the “Max” option to swap your entire POL balance (leaving some for network fees).

4. Adjust Slippage Tolerance

Depending on market conditions, you might need to adjust the slippage tolerance. This ensures your trade goes through even if the price changes slightly during the transaction. You can do this in the Uniswap “Settings” menu. We recommend using the “Auto” for slippage.

5. Approve POL for Spending

If this is your first time swapping POL for $CHECK, Uniswap will prompt you to approve POL for spending. Confirm the approval in your wallet. This is a one-time transaction per token.

6. Confirm the Swap

Click “Swap” in the Uniswap interface, review the transaction details, and confirm. Your wallet will prompt you to confirm the swap and pay the network fee.

7. Wait for Blockchain Confirmation

After confirming, wait for the transaction to be processed on the Polygon blockchain. Once complete, you’ll see your $CHECK tokens in your wallet.

You can track your transaction status and view your swap on Polygonscan by clicking “View on Explorer” after your swap is submitted.

Trading on Uniswap is a straightforward process that leverages the platform’s decentralized and user-friendly design, making it accessible to both new and experienced crypto users.
