Aptos Joins Open USD as Native Launch Chain

Aptos Labs announced on July 1, 2026 that it has joined the Open Standard consortium as a founding partner and will be a native launch chain for Open USD, the dollar-pegged stablecoin backed by more than 140 companies including Visa, Mastercard, Stripe and BlackRock.

Open USD was unveiled on June 30, 2026 as a business-focused stablecoin backed 1:1 by cash and short-term U.S. Treasuries held at major financial institutions. The consortium model includes payment networks, banks, exchanges and cloud providers and sets zero fees for minting and redemption, no volume caps, and a reserve-yield distribution that returns nearly all earnings to partners after a small management fee.

Aptos is one of four confirmed native launch chains alongside Solana, Polygon and Stellar. Native issuance on Aptos means Open USD will be minted directly on the Aptos blockchain rather than bridged from another network, removing bridge risk and placing OUSD on Aptos under the same on-chain trust model used by primary-chain USDC and USDT. The consortium has indicated initial live launches will begin on Plasma and Solana, with additional networks, including Aptos, planned later in 2026.

Aptos is a Layer 1 blockchain built on the Move programming language, designed for high throughput, sub-second finality and parallel transaction execution. The network launched in October 2022 and supports stablecoin integrations including USDC, USDT and Ondo Finance’s USDY, along with BlackRock’s BUIDL. Aptos’s stablecoin ecosystem crossed $2 billion in total market capitalization in June 2026, an amount disclosed alongside the Open USD partnership announcement.

The economic design of Open USD differs from many existing dollar stablecoins by sharing nearly all reserve yield with consortium partners instead of retaining it at the issuer level. As a consortium member, Aptos and its partners stand to receive a share of reserve yield proportional to Open USD activity on the Aptos network. Stripe has committed to making OUSD the default stablecoin for businesses on its platform, which could route merchant settlement volume to networks that host native OUSD issuance.

Open Standard governance is handled by a partner-led board rather than a single controlling company. Market participants flagged operational risks ahead of launch, including potential governance friction among many partners and the difficulty of building initial liquidity. Financial markets reacted to the June 30 announcement with notable moves in related equities; Circle shares fell 18% on the day as investors priced increased competition in the dollar stablecoin market.

Open USD is expected to go live later in 2026. The consortium and Aptos have said the effectiveness of the arrangement will be measurable once native issuance and settlement volumes begin on the initial networks.
