# Contract Addresses

> **Source of truth for addresses:** DEX addresses are mirrored from [`integrator-kit/addresses/`](https://github.com/Kumbaya-xyz/integrator-kit/tree/main/addresses). Launchpad (`Fire*`) contract addresses are sourced from the Kumbaya frontend's `constants/fire.ts`, which is the canonical reference for currently-active deployments and parameters. If they disagree with this page, please open an issue.
>
> The `fire/addresses/megaETH-mainnet.json` snapshot in the [fire repo](https://github.com/Kumbaya-xyz/fire/tree/main/addresses) reflects **initial deployment state** - addresses are still correct, but other fields (`paused`, `requiredVestingDuration`, etc.) may have been updated by governance since deploy. **Read the registry on-chain for live config values** - see [Live registry config](/developers/building-agents/registry-config.md).

> 🛡 **All contracts on this page are audited.** The Kumbaya V3 fork inherits Uniswap V3's audits (Trail of Bits + ABDK) and is bytecode-verified against upstream. The Kumbaya launchpad - including `FireToken` - has a signed BlockSec audit. See [**Audit & security**](/developers/audit-and-security.md) for full reports and the trust model.

## Pool init code hash

Same on both networks. Used for off-chain pool address derivation.

```
0x851d77a45b8b9a205fb9f44cb829cceba85282714d2603d601840640628a3da7
```

This is **different from upstream Uniswap V3** - see [**Pool Init Code Hash**](/developers/dex-integration/pool-init-code-hash.md).

## Programmatic access

Both repos publish the addresses as plain JSON, so you can import them directly:

```ts
import addresses from '../integrator-kit/addresses/megaETH-mainnet.json'
const factory = addresses.UniswapV3Factory
```

The launchpad addresses on this page are pinned for mainnet and testnet - those don't change once deployed. For other config values (grace period, vesting duration, recipient list, etc.), read the registry on-chain rather than trusting any JSON snapshot - see [Live registry config](/developers/building-agents/registry-config.md).
