AMM DEX

Uniswap V2 / PancakeSwap V2-compatible AMM deployed on the Calix EVM. Permissionless liquidity pools, 0.3% swap fee, and fully open-source contracts.

How It Works

The DEX uses the constant-product formula x · y = k. Any address can create a trading pair via the factory; the pair contract mints LP tokens representing a proportional share of the pool. All pairs are deployed via CREATE2, so addresses are deterministic and can be computed off-chain.

Swap fee: 0.3% (retained in the pool, accrues to LPs)
LP tokens are standard CLX20 (ERC-20) — transferable and stakeable
No protocol fee by default; governance may enable a 0.05% treasury cut

💡

PancakeSwap V2 compatible. PancakeSwap V2 is a fork of Uniswap V2 and shares the same contract interface. Any SDK, tool, or frontend built for PancakeSwap V2 works on Calix DEX without modification — just switch to the Calix RPC endpoint and contract addresses.

Deployed Contracts

Contract	Description	Address
`WCLX`	Wrapped CLX — ERC-20 wrapper for native CLX	Available at launch
`UniswapV2Factory`	Deploys and indexes all pairs	Available at launch
`UniswapV2Pair`	Per-pair AMM pool (deployed by factory)	CREATE2
`UniswapV2Router02`	User-facing router: swap, add/remove liquidity	Available at launch

Key Operations

Function	Router Method	Notes
Add liquidity (tokens)	`addLiquidity`	Deposits tokenA + tokenB, mints LP tokens
Add liquidity (native CLX)	`addLiquidityCLX`	Wraps CLX to WCLX internally
Remove liquidity	`removeLiquidity`	Burns LP tokens, returns underlying tokens
Swap tokens → tokens	`swapExactTokensForTokens`	Exact input, minimum output enforced
Swap CLX → tokens	`swapExactCLXForTokens`	Send CLX as msg.value
Swap tokens → CLX	`swapExactTokensForCLX`	Unwraps WCLX, sends native CLX to recipient

ethers.js Integration

import { ethers } from "ethers";
import RouterABI from "./abi/UniswapV2Router02.json";

const ROUTER_ADDRESS = "0x..."; // Available at launch — see /scan for verified address

const provider = new ethers.JsonRpcProvider("https://calixchain.io/rpc");
const signer   = await provider.getSigner();
const router   = new ethers.Contract(ROUTER_ADDRESS, RouterABI, signer);

// Swap exact 1 CLX for tokens
const tx = await router.swapExactCLXForTokens(
  amountOutMin,
  [WCLX_ADDRESS, tokenAddress],
  recipientAddress,
  Math.floor(Date.now() / 1000) + 300,   // deadline: 5 min
  { value: ethers.parseEther("1") }
);
await tx.wait();
