TeQoin L2 Blockchain Documentation - Developer Guides & API Reference

TeQoin offers a unique combination of low fees, high speed, and Ethereum security that makes it the ideal Layer-2 solution for developers and users alike.

The Problem with Ethereum L1

While Ethereum is the leading smart contract platform, it faces significant challenges:

High Gas Fees

Simple transactions can cost $5-$50+ during network congestion

Slow Transactions

12-15 second block times feel sluggish for modern applications.

Limited Throughput

Only 15-30 transactions per second creates bottlenecks

Poor UX

High fees and slow speeds create friction for users

Real-World Impact

User Action: Swap $50 worth of tokens
L1 Gas Fee: $25
User Experience: 😞 "Why am I paying 50% in fees?"

User Action: Mint an NFT
L1 Scenario: Bot-driven Gas War 
User Experience: 😠 "This costs more than the NFT itself! only whales won."

User Action: Play a blockchain game
L1 Gas Fee: $10 per move
User Experience: 😤 "This is unplayable!"

How TeQoin Solves This

TeQoin eliminates these pain points while maintaining the security guarantees you expect from Ethereum.

💰 Low Transaction Fees

The most compelling reason to use TeQoin is simple: users pay low in gas fees.

For Users

Make transactions without worrying about gas costs

For Developers

Build applications without users complaining about fees

For Businesses

Predictable costs and better unit economics

For Innovation

Enable new use cases that weren’t viable on L1

⚡ Lightning-Fast Performance

5-second block times provide instant transaction confirmation.

Anti-MEV Advantage

    Ethereum L1:
    Click "Send" → Wait 12-15 seconds → Transaction confirmed
    User thinks: "Is this still processing?"
    
    TeQoin L2:
    Click "Send" → Wait 5 seconds → Transaction confirmed
    User thinks: "Wow, that was fast!"

Block Time	12-15 seconds	5 seconds
TPS	15-30	1000+

🔒 Ethereum-Grade Security

TeQoin doesn’t compromise on security to achieve speed and low costs.

Inherits Ethereum Security

All transaction data is posted to Ethereum L1. This means TeQoin’s security is backed by Ethereum’s $40B+ network, making it as secure as Ethereum itself.

Fraud Proof Protection

If the TeQoin sequencer submits invalid transactions, anyone can challenge them with fraud proofs. Invalid transactions are automatically reverted, protecting user funds.

No Trust Required

You don’t need to trust the TeQoin team or sequencer. Security is enforced by Ethereum smart contracts and cryptographic fraud proofs.

Censorship Resistance

If the sequencer censors your transactions, you can force them through Ethereum L1 directly. The network remains accessible even if the sequencer is malicious or offline.

🛠️ Full EVM Compatibility

Zero learning curve. Use the exact same tools, libraries, and code you already know.

// Same code works on both Ethereum and TeQoin
const provider = new ethers.providers.Web3Provider(window.ethereum);
await provider.send("eth_requestAccounts", []);

// Just change the network - everything else stays the same!

// Your existing contracts work on TeQoin with ZERO changes
contract MyDApp {
    mapping(address => uint256) public balances;
    
    function deposit() public payable {
        balances[msg.sender] += msg.value;
    }
    
    function withdraw(uint256 amount) public {
        require(balances[msg.sender] >= amount);
        balances[msg.sender] -= amount;
        payable(msg.sender).transfer(amount);
    }
}

TeQoin vs. Alternatives

Why TeQoin vs. Other L2s?

Feature	TeQoin	Optimism	Arbitrum	Base	zkSync
Block Time	5 sec	2 sec	~0.25 sec	2 sec	~10 sec
Architecture	Optimistic(Future ZK-Ready)	Optimistic	Optimistic	ZK-Rollup
EVM Compatibility	100%	100%	100%	100%	~95%
Withdrawal Time	7 day-> Minutes	7 days	7 days	7 days	Minutes-Hours

Built for the Future: TeQoin uses a Diamond architecture, making it the only L2 that is truly modular. While other L2s require massive, risky “hard forks” to change their tech, TeQoin can “hot-swap” its internal logic. This allows us to evolve from Optimistic to Zero-Knowledge (ZK) seamlessly over time, constantly lowering costs and withdrawal times without ever disrupting the ecosystem.
