Contracts

Smart contract addresses for BaiDEX core, fee router, Spawner, and registry.

Production contract addresses on BiniChain mainnet will be published here. Until mainnet launch, the canonical deployment is on Base Sepolia (testnet).

Standard V3 contracts

The following Uniswap V3 contracts are deployed alongside, with addresses to be published in a follow-up PR (or on BiniChain mainnet when launched):

• UniswapV3Factory — pool factory
• NonfungiblePositionManager — LP position NFTs
• SwapRouter02 — primary swap router (use this for exactInputSingle etc.)
• Quoter — off-chain quote helper
• TickLens — tick query helper
• UniversalRouter — multi-protocol router (if deployed)

BiniChain mainnet (future)

When BiniChain mainnet launches, the canonical deploy will publish:

• All addresses above (renamed without “BaiDex” prefix where applicable)
• Bridge contracts (Bridge A, Bridge B)
• Anchor pool address (the canonical wBINI/USBI pool)

This page will be updated automatically from CI when the deploy happens.

Roles & access

Contract	Role	Granted to (testnet)
USBI	MINTER_ROLE	Deployer (will move to bridge contract on mainnet)
USBI	BURNER_ROLE	Deployer
HiveSpawner	DEFAULT_ADMIN_ROLE	Deployer
HiveRegistry	DEFAULT_ADMIN_ROLE	Deployer

Mainnet roles will move to multisigs / governance contracts before launch.

Verification

All contracts are verified on Blockscout. View source code:

Contract	Source
BaiDexFeeRouter	contracts/BaiDexFeeRouter.sol
HiveSpawner	contracts/HiveSpawner.sol
SpawnedERC20 (template)	contracts/SpawnedERC20.sol
HiveRegistry	contracts/HiveRegistry.sol
USBI	contracts/USBI.sol
WBINI	contracts/WBINI.sol

Open-source repository: link will publish with mainnet.

Test results

The Base Sepolia deploy passed 37/37 tests:

• 4 smoke tests (deploy verification, basic ops)
• 18 extended tests (full contract interactions, fee math)
• 15 V3 pool tests (pool creation, swap through FeeRouter, fee split verification)

Deployer

Address: 0x8CAD91D7b423Ac728eA49077AD7030a593377a04
RPC:     https://sepolia.base.org (testnet) / https://rpc.binibit.com (mainnet)

The deployer key has rotation planned before mainnet — final mainnet deployer will be a multisig.

ABI access

ABIs for all BaiDEX contracts are published in the @binibit/contracts npm package (when published) or fetchable from BiniChain explorer when verified.

For now, ABIs are available on request from [e-mail].
