Integrator Kit

The integrator-kit repo is the operational source of truth for integrators: addresses, ABIs, and Foundry tests that exercise the live deployments on MegaETH.

What's in it

Path	Contents
addresses/	One JSON file per chain (megaETH-mainnet.json, megaETH-testnet.json) with all deployed addresses
abis/	13 contract ABIs: ERC-20, V3 Factory & Pool, NonfungiblePositionManager, Permit2, QuoterV2, SwapRouter02, UniversalRouter, TickLens, etc.
scripts/	fetch-abis.ts (regenerate ABIs from artifacts) and compare-bytecode.ts (validate against Uniswap V3)
tests/megaETH/	Foundry Solidity integration tests that hit the live MegaETH deployments - useful as reference for quoting, swapping, pool address derivation, WETH wrapping
audits/	Signed audit reports - currently the BlockSec audit of the Kumbaya launchpad contracts. See Audit & security for the full breakdown
README.md	Full integration guide with installation and example commands

When to reach for it

• Confirming a contract address - addresses/megaETH-mainnet.json is canonical

• Pulling an ABI for off-chain encoding - copy from abis/

• Sanity-checking your integration - clone the repo, run the Foundry tests, compare against your own behavior

• Verifying our V3 fork is bytecode-equivalent to upstream (where it should be) - compare-bytecode.ts

Launchpad addresses

Note: integrator-kit currently holds DEX addresses only. The Kumbaya launchpad (Fire*) contract addresses are listed in the consolidated table in Contract Addresses.

The fire/addresses/megaETH-mainnet.json file in the fire repo is an initial-deployment snapshot - addresses are still accurate, but other fields like paused and requiredVestingDuration may have been changed by governance since deploy. For live config values, read the registry on-chain (see Live registry config).
