\* RPC nodes that enable Anti-MEV support will not broadcast any normal transaction. Please refer [Envelope Transaction](/security/anti-mev-protection/constructing-envelope-transactions.md) for their proper usage.

<table><thead><tr><th width="170">Name</th><th width="100">Network</th><th width="480">Address</th></tr></thead><tbody><tr><td>CREATE2 Deployer</td><td>Mainnet</td><td><a href="https://xexplorer.neo.org/address/0x4e59b44847b379578588920ca78fbf26c0b4956c"><code>0x4e59b44847b379578588920cA78FbF26c0B4956C</code></a></td></tr><tr><td></td><td>Testnet</td><td><a href="https://xt4scan.ngd.network/address/0x4e59b44847b379578588920ca78fbf26c0b4956c"><code>0x4e59b44847b379578588920cA78FbF26c0B4956C</code></a></td></tr></tbody></table>

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.

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

<table><thead><tr><th width="150">Name</th><th width="100">Network</th><th width="500">Address</th></tr></thead><tbody><tr><td>Multicall3</td><td>Mainnet</td><td><a href="https://xexplorer.neo.org/address/0xD6010D102015fEa9cB3a9AbFBB51994c0Fd6E672"><code>0xD6010D102015fEa9cB3a9AbFBB51994c0Fd6E672</code></a></td></tr><tr><td></td><td>Testnet</td><td><a href="https://xt4scan.ngd.network/address/0x82096F92248dF7afDdef72E545F06e5be0cf0F99"><code>0x82096F92248dF7afDdef72E545F06e5be0cf0F99</code></a></td></tr></tbody></table>

Utility contracts provide reusable functionality for interacting with the network. Multicall3 enables batching multiple contract calls into a single request.

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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://xdocs.ngd.network/development/networks.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
