OUSD networks and contract addresses

Open USD (OUSD) is available on Base, Ethereum, Solana, and Tempo. A network connects the computers that maintain a 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 is a program that runs on a blockchain. Token contracts keep track of balances and apply rules for transfers.

A 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: the record defining the token, with individual balances held in separate token accounts.

Official OUSD addresses

These entries identify native OUSD, meaning OUSD issued directly on each blockchain. The launch announcement confirms native issuance. Addresses and explorer links come from Open Standard; 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 permission or a testnet.
