# OUSD networks and contract addresses

Open USD (OUSD) is available on Base, Ethereum, Solana, and Tempo. A [network](https://openusd.dev/guides/concepts/#network) connects the computers that maintain a [blockchain](https://openusd.dev/guides/concepts/#blockchain), a shared record of transactions and token balances. Each network keeps its own records, so the network matters as much as the token address.

## What is a contract address?

A [smart contract](https://openusd.dev/guides/concepts/#smart-contract) is a program that runs on a blockchain. [Token contracts keep track of balances and apply rules for transfers.](https://ethereum.org/developers/docs/standards/tokens/erc-20/)

A [token address](https://openusd.dev/guides/concepts/#token-address) is the exact identifier used to find OUSD on a particular network. On Base, Ethereum, and Tempo, the addresses below identify OUSD token contracts. On Solana, the address identifies OUSD’s [mint account](https://openusd.dev/guides/concepts/#mint-account): the record defining the token, with individual balances held in separate token accounts.

## Official OUSD addresses

These entries identify [native OUSD](https://openusd.dev/guides/concepts/#native-and-bridged-tokens), meaning OUSD issued directly on each blockchain. The [launch announcement](https://joinopenstandard.com/blog/ousd-is-live) confirms native issuance. Addresses and explorer links come from [Open Standard](https://joinopenstandard.com/integrate); address review dates: 2026-10-12.

## How you use these addresses

-   **Check identity:** compare the network and full address when a wallet or service shows OUSD.
-   **Inspect activity:** open the explorer to look up token details, holders, and transfers.
-   **Build an integration:** use the network and token address together to identify OUSD when reading balances or tracking transfers.

**These are token identifiers, not your personal receiving addresses.** Don’t send funds directly to the listed addresses. Provider support, account eligibility, and onboarding are separate; check your chosen provider’s documentation. A native deployment does not establish [minting](https://openusd.dev/guides/concepts/#minting-and-redemption) permission or a [testnet](https://openusd.dev/guides/concepts/#mainnet-testnet-and-sandbox).
