Coinbase Launches Open USD Transfers on Base, Ethereum, Solana, and Tempo

Coinbase has officially launched the ability for users to send and receive Open USD (OUSD) across four blockchain networks: Base, Ethereum, Solana, and Tempo. This feature became available in supported regions just one day after OUSD went live on September 30, 2026.

The integration allows users to move OUSD in and out of their Coinbase accounts on these networks, providing flexibility for holding and transferring the token. Coinbase is not only a platform for OUSD but also one of its founding partners, alongside major companies like Mastercard, Shopify, Stripe, and Visa. Each partner holds equal equity in the project, which is designed to operate under a consortium model rather than being controlled by a single issuer.

OUSD aims to compete with established dollar-pegged stablecoins such as Tether's USDT and Circle's USDC. The consortium backing OUSD has committed over $1 billion in liquidity, with significant contributions from Stripe’s new Layer 1 network, Tempo, which added over $400 million in initial liquidity.

For businesses, OUSD offers a cost-effective solution, allowing companies to mint and redeem the stablecoin at a 1:1 ratio with the dollar without fees or volume limits. Reserves for OUSD are held by reputable custodians like BlackRock and BNY, with monthly attestations ensuring the backing assets are verified.

As Coinbase looks to expand the adoption of OUSD, the immediate impact for users is the introduction of another dollar token in the app, backed by established reserves and movable across multiple chains. The success of this initiative will depend on how quickly the committed liquidity translates into trading volume and whether other exchanges will support OUSD in the future.
