Deployed Contracts

Core Infrastructure

Name	Network	Address
CREATE2 Deployer	Mainnet	0x4e59b44847b379578588920cA78FbF26c0B4956C
	Testnet	0x4e59b44847b379578588920cA78FbF26c0B4956C
CreateX	Mainnet	0xba5Ed099633D3B313e4D5F7bdc1305d3c28ba5Ed
	Testnet	0xba5Ed099633D3B313e4D5F7bdc1305d3c28ba5Ed

Core infrastructure contracts provide fundamental primitives used across the ecosystem. The CREATE2 Deployer enables deterministic contract deployments via CREATE2 and matches the canonical Ethereum deployer at the same address. CreateX is an extensible deployment factory for CREATE, CREATE2, and CREATE3-based contract creation, including clone and deploy-and-init workflows.

Account abstraction infrastructure provides the canonical ERC-4337 EntryPoint contracts used by smart accounts, bundlers, paymasters, and related account abstraction tooling.

The EntryPoint is a critical singleton contract for ERC-4337. Different wallets and bundlers may depend on different EntryPoint versions, so Neo X provides deployments for v0.6, v0.7, v0.8, and v0.9. The contracts are deployed at the same deterministic addresses as on other EVM networks using CREATE2.

Utilities

Multicall3	Mainnet	0xD6010D102015fEa9cB3a9AbFBB51994c0Fd6E672

	Testnet	0x000000000022D473030F116dDEE9F6B43aC78BA3

Utility contracts provide reusable functionality for interacting with the network. Multicall3 enables batching multiple contract calls into a single request. Permit2 enables signature-based token approvals and transfers.

Assets

WGAS10	Mainnet	0xdE41591ED1f8ED1484aC2CD8ca0876428de60EfF

	Testnet	0x3eE9da67D85475a250423138cBf56aF511277958

Asset contracts represent tokenized value on Neo X.

• WGAS10 wraps native GAS with a WETH9-compatible design and implements ERC-3156 flash loans.

• xGAS is an immutable wrapped native GAS asset that extends standard ERC-20 behavior with explicit permit and transfer-authorization support (EIP-2612, EIP-3009, EIP-712), plus ERC-1271-compatible encoded-signature extensions.

Integrations

x402ExactPermit2Proxy	Mainnet	0x402085c248EeA27D92E8b30b2C58ed07f9E20001
	Testnet	0x402085c248EeA27D92E8b30b2C58ed07f9E20001

Integration contracts enable higher-level workflows built on top of Neo X. The x402ExactPermit2Proxy is a Permit2-based x402 settlement contract for exact-amount, witness-bound payments.
