description: "All Avalanche system contracts — precompiles, WAVAX, Teleporter, DEX routers, and lending protocols on Mainnet and Fuji."
trigger: |
  Use when: user needs a contract address on Avalanche C-Chain (WAVAX, Teleporter, Trader Joe, BENQI, Aave, precompiles), or asks 'what is the address of X on Avalanche'.
  Do NOT use for: custom Subnet addresses (those are set at genesis), Ethereum mainnet addresses.

## Overview

A complete address reference for Avalanche C-Chain. Precompile addresses are the same on every Subnet-EVM chain. DeFi protocol addresses are mainnet-specific. Always verify addresses from official sources before using in production.

## When to fetch

Fetch whenever a user needs a specific contract address on Avalanche. This is a reference skill — no workflow, just addresses.

## System Precompiles (Same on ALL Subnet-EVM chains)

| Precompile | Address | Function |
|---|---|---|
| ContractDeployerAllowList | 0x0200000000000000000000000000000000000000 | Restrict contract deployment |
| NativeMinter | 0x0200000000000000000000000000000000000001 | Mint native gas token |
| TxAllowList | 0x0200000000000000000000000000000000000002 | Restrict transaction senders |
| FeeManager | 0x0200000000000000000000000000000000000003 | Dynamic fee adjustment |
| RewardManager | 0x0200000000000000000000000000000000000004 | Validator reward config |
| WarpMessenger | 0x0200000000000000000000000000000000000005 | Cross-chain Warp messaging |

Note: Precompiles only exist if enabled in genesis. Calling a disabled precompile reverts.

## Fuji Testnet (Chain ID: 43113)

| Contract | Address | Notes |
|---|---|---|
| Teleporter Messenger | 0x253b2784c75e510dD0fF1da844684a1aC0aa5fcf | Same as mainnet |
| WAVAX (Fuji) | 0xd00ae08403B9bbb9124bB305C09058E32C39A48c | Test WAVAX |

Most mainnet DeFi protocols don't have Fuji deployments. For testing, deploy your own mock contracts.

## Useful ABI Fragments

**WAVAX (deposit/withdraw):**
```solidity
interface IWAVAX {
    function deposit() external payable;
    function withdraw(uint256 amount) external;
    function balanceOf(address) external view returns (uint256);
    function approve(address spender, uint256 amount) external returns (bool);
    function transfer(address to, uint256 amount) external returns (bool);
}
```

**Trader Joe Router v2.1:**
```solidity
interface IJoeRouter {
    function swapExactTokensForTokens(
        uint amountIn, uint amountOutMin,
        address[] calldata path, address to, uint deadline
    ) external returns (uint[] memory amounts);
    
    function swapExactAVAXForTokens(
        uint amountOutMin, address[] calldata path,
        address to, uint deadline
    ) external payable returns (uint[] memory amounts);
}
```

**Aave Pool:**
```solidity
interface IAavePool {
    function supply(address asset, uint256 amount, address onBehalfOf, uint16 referralCode) external;
    function withdraw(address asset, uint256 amount, address to) external returns (uint256);
    function borrow(address asset, uint256 amount, uint256 interestRateMode, uint16 referralCode, address onBehalfOf) external;
    function repay(address asset, uint256 amount, uint256 interestRateMode, address onBehalfOf) external returns (uint256);
}
```

## Key concepts

**Precompile addresses** — Fixed at 0x0200... — these are the same on every Subnet-EVM chain regardless of network. Only active if enabled in genesis.

**USDC vs USDC.e** — `0xB97EF9...` is native USDC (Circle's official cross-chain transfer protocol). `0xA7D707...` is bridged USDC from the old Avalanche Bridge. For new projects, use native USDC.

**Address checksum** — Ethereum addresses are checksummed (mixed case). `0xB31f66AA3C1e785363F0875A1B74E27b85FD66c7` (checksummed) = `0xb31f66aa3c1e785363f0875a1b74e27b85fd66c7` (lowercase). Both work.

## Common errors

| Error | Cause | Fix |
|---|---|---|
| Precompile call reverts | Precompile not enabled in genesis | Enable in genesis or call admin to enable |
| "Contract not found" | Using mainnet address on Fuji | Fuji has different addresses for most DeFi |
| USDC.e vs USDC confusion | Using wrong USDC address | Use 0xB97EF9... for modern USDC, check bridge docs |

## Core Workflow

1. Identify the network (C-Chain mainnet 43114 / Fuji 43113 / custom Subnet)
2. Look up the address in this skill or the official Avalanche docs
3. Confirm address on the block explorer before hardcoding
4. For precompiles: address is deterministic — same on every Subnet-EVM chain
5. For DeFi contracts: mainnet and Fuji addresses differ — never copy-paste across networks
