# Smart Contracts

Official USD8 contract addresses on HyperEVM mainnet (chain ID 999). Always verify before interacting.

This page centralises the official contract deployments of the USD8 protocol. All contracts live on **HyperEVM mainnet (chain ID 999)** and are verified with exact-match source code.

{% hint style="danger" %}
**Always verify addresses on this page before interacting.** USD8 will never ask you to send funds directly to a contract address — use the [USD8 app](https://app.usd8.ai). Be cautious of similar-looking addresses.

Deployment notes: all contracts were deployed at block `45518186` (the standby Backup Price Adapter at block `45607734`) and verified with exact-match source on Sourcify. The deployer address holds **zero remaining roles** — administration rests entirely with the timelocked governance described in [Security & Audits](/transparency/security-and-audits.md).
