Open USD (OUSD), the stablecoin built by OpenStandard and backed by Stripe subsidiary Bridge, is now live on Tempo, the Layer 1 blockchain developed by Stripe and Paradigm, with more than $400 million in liquidity on the chain.

The integration targets enterprise payments, settlement, and treasury management — the three verticals Tempo has prioritized since its mainnet launch on March 18, 2026, when the chain went live with a narrow mandate: stablecoin payments at scale.

OUSD's reserve structure and economics

OUSD's reserves are held at BlackRock, Lead Bank, and BNY. The token's economics are built to be unusually partner-friendly. There are zero mint or redeem fees and no volume caps, which means enterprises can move large sums without per-transaction costs eating into treasury operations. Partners can capture nearly all of the reserve earnings, with only a small management fee retained by the issuer.

Between 140 and 200 businesses participate in OUSD's collaborative framework. Reported participants include Visa, Mastercard, and Coinbase, according to the announcement.

The stablecoin first went live on September 30, 2026, across multiple chains including Base, Ethereum, and Solana. The fact that over $400 million in liquidity has concentrated on Tempo alone suggests institutional demand is settling on the Stripe-backed chain rather than distributing evenly across the token's multi-chain deployments.

Tempo's rails

Tempo's technical profile is tailored to high-volume corporate settlement. Average transaction fees sit below $0.001. At that rate, a company settling a million transactions per month would pay less than $1,000 in total network fees — a cost structure that makes on-chain settlement viable for payment operations that traditional card rails and wire systems handle today.

The chain also ships with two purpose-built primitives. A native stablecoin decentralized exchange handles swaps between stablecoin denominations on-chain, and a Fee Automated Market Maker is designed to keep operational liquidity flowing across the network, reducing slippage and fragmentation risk for corporates running continuous payment flows.

What it means for enterprise adoption

The operational consequence of the integration is straightforward: businesses already inside the OUSD collaborative framework — payments networks, exchanges, and corporate treasuries — gain a direct on-ramp for payments, settlement, and treasury operations on a chain with sub-mill transaction costs and native stablecoin infrastructure.

For Stripe and Paradigm, the deployment reinforces Tempo's positioning as the most enterprise-focused Layer 1 in the sector. For OpenStandard and Bridge, it extends OUSD's distribution from general-purpose chains (Base, Ethereum, Solana) into a purpose-built payments environment where stablecoin liquidity is the core product rather than a complementary one.

The concentration of $400 million in OUSD liquidity on Tempo within months of the stablecoin's multi-chain launch signals that enterprise payment flows — not retail trading — are becoming the primary driver of stablecoin deployment decisions. As corporate participants continue onboarding into the OUSD framework and Tempo's stablecoin-native infrastructure matures, the competitive pressure on general-purpose chains to justify their fee structures for settlement workloads will only intensify.
