Contract Addresses

Source of truth for addresses: DEX addresses are mirrored from integrator-kit/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 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.

🛡 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 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.

Programmatic access

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

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.
