KongSwap Router: Swap any pair of tokens with no gas fees

In the world of decentralized exchanges, one of the biggest challenges users face is finding liquidity to swap between tokens that don't have a direct trading pair. Traditional DEXs often require users to manually figure out swap routes, leading to confusion, inefficiency, and poor pricing. KongSwap solves this problem with its intelligent router that automatically finds the best path to swap between any two tokens on the platform.

The Problem with Traditional DEXs

Imagine you want to swap Token A for Token C, but there's no direct A-C liquidity pool. On many DEXs, you would need to:

  1. Manually find an intermediate token (like Token B)
  2. Execute two separate transactions (A → B, then B → C)
  3. Pay gas fees twice
  4. Risk price changes between transactions
  5. Calculate slippage for each hop manually

This process is not only cumbersome but also expensive and risky. It creates a poor user experience and often results in worse pricing due to inefficient routing.

How KongSwap's Router Works

KongSwap's router is a sophisticated pathfinding algorithm that automatically discovers the optimal route between any two tokens. Here's how it works:

1. Automatic Path Discovery

When you request a swap, the router instantly analyzes all available liquidity pools to find possible paths. For example, if you want to swap KONG to ckBTC, the router might find:

  • Direct route: KONG → ckBTC (if a pool exists)
  • Multi-hop routes: KONG → ICP → ckBTC, or KONG → ckUSDT → ckBTC

Note: Routes are currently limited to two hops and use one of our supported quote tokens — ICP or ckUSDT — as the intermediate asset.

2. Multi-Hop Optimization

The router doesn't just find any path – it finds the best path. It considers:

  • Liquidity depth in each pool
  • Trading fees for each hop
  • Price impact across the entire route
  • Gas costs for the transaction

3. Single Transaction Execution

Unlike traditional DEXs that require multiple transactions for multi-hop swaps, KongSwap executes the entire route in a single atomic transaction. This means:

  • One approval (for tokens that require it)
  • One gas fee
  • No risk of partial execution
  • Guaranteed price or transaction reverts

Real-World Example: Swapping Any Token to Any Token

Let's look at a practical example of how the router enables universal swapping:

Scenario: You want to swap 1000 MOTOKO tokens for EXE tokens

The router might find several paths:

  1. MOTOKO → ICP → EXE (2 hops)
  2. MOTOKO → ckUSDT → EXE (2 hops)

The router automatically selects the path that gives you the most EXE tokens after accounting for all fees and price impacts.

How It's Built

Single Canister Architecture

KongSwap's router leverages a single canister architecture and the Internet Computer's stable memory to maintain a real-time graph of all liquidity pools and their relationships. This enables:

  • Instant path calculation without external dependencies
  • No reliance on off-chain indexers or oracles
  • Fully decentralized routing logic
  • Faster swap execution

Smart Fee Optimization

The router intelligently accounts for different fee structures:

  • LP fees: Varying by pool (typically 0.3%)
  • Token-specific fees: Some tokens have transfer fees built in

Benefits for Users

1. Access to Deep Liquidity

By aggregating liquidity across all pools, users get better pricing than if they were limited to direct pairs only.

2. Simplified User Experience

Users don't need to understand liquidity pools or routing. They simply:

  1. Select the token they want to pay with
  2. Select the token they want to receive
  3. Enter the amount
  4. Click swap

The router handles all the complexity behind the scenes.

3. Better Price Execution

Multi-path routing often results in better prices than direct swaps, especially for larger trades where single pools might have high slippage.

4. Future-Proof Design

As new tokens and pools are added to KongSwap, they're automatically included in the router's pathfinding, ensuring users always have access to the best liquidity.

Looking Ahead: The Future of KongSwap Routing

Cross-Chain Routing

With Chain Fusion integration coming soon, the router will extend its capabilities to find paths across different blockchains like:

  • Swap Bitcoin for Solana tokens
  • Route for optimal liquidity and slippage across chains

Conclusion

KongSwap's router represents a fundamental improvement in how users interact with decentralized exchanges. By abstracting away the complexity of finding swap paths and optimizing for the best execution, it delivers on the promise of making DeFi accessible to everyone.

Whether you're swapping between major tokens or obscure meme coins, the router ensures you get the best possible price with minimal effort. This is the power of true interoperability – any token to any token, in one click, with optimal pricing.

As KongSwap continues to grow and add new features, the router will remain at the heart of the user experience, constantly evolving to provide even better swaps for the community.
