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 use the same CREATE2-based deployment scheme and canonical addresses as the corresponding upstream releases, allowing their deployment bytecode and runtime bytecode to be independently checked against those releases.

The governance-sponsored gas abstraction flow using GovPaymaster currently targets EntryPoint v0.9. GovPaymaster is coupled to that EntryPoint version, and the documented Altpool endpoints advertise support for it. The other canonical EntryPoint deployments are available for compatible wallets and independently operated Bundlers; their availability does not by itself imply GovPaymaster sponsorship support.

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.

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.
