DoorDash, Nium and Ramp Drive Stablecoin into Everyday Payments
Three separate announcements on April 21 and 22 mark a measurable step toward stablecoin adoption in operational payment flows: DoorDash is deploying stablecoin payouts via the Tempo blockchain, Singapore-based Nium is integrating USDC across 190 countries through Coinbase, and fintech firm Ramp has introduced zero-fee conversions between US dollars and USDT. Taken together, and set against a fresh all-time high of $188 billion in USDT circulating supply, the cluster of moves suggests that enterprise demand for stablecoin settlement infrastructure has shifted from pilot to production.
DoorDash and Tempo Bring Stablecoin Rails to 40 Countries
DoorDash, which processed nearly $75 billion in merchant sales last year and delivered 903 million orders in Q4 2025 alone, confirmed it is building stablecoin-powered payment infrastructure with Tempo, a payments-focused blockchain developed by Stripe and venture firm Paradigm. The rollout begins with cross-border merchant payouts, with Dasher compensation to follow. “If we can get merchants and Dashers their money faster, and do that in a way that’s affordable for them, that’s a no-brainer for the entire ecosystem,” said DoorDash co-founder Andy Wang. Tempo offers sub-second settlement, fixed dollar-denominated fees, and private transaction channels designed specifically for high-frequency enterprise payout flows, features that general-purpose blockchains have struggled to provide at scale.
Stripe’s role in this ecosystem is substantial. The company processes close to $2 trillion in annual payments, acquired stablecoin infrastructure firm Bridge for $1.1 billion in 2024, and has since added crypto wallet provider Privy to its stack. Tempo’s broader infrastructure partners include Mastercard, UBS, Klarna, and Visa, alongside Latin American fintech ARQ and Coastal Bank. A full deployment timeline has not been disclosed, as Decrypt reported, but the companies confirmed active testing and phased integration.
Nium, Ramp and the USDT Supply Record
Separately, Nium announced it has selected Coinbase to integrate USDC into its cross-border payment network, which spans more than 190 countries, supports over 100 currencies, and holds more than 40 regulatory licenses. The arrangement uses Coinbase infrastructure for custody, liquidity and wallet services, enabling just-in-time settlement rather than prefunded accounts held across multiple jurisdictions, a structural cost improvement for businesses managing global payroll or supplier payments. Nium’s network already supports real-time payouts in more than 100 corridors, and the integration includes an option to link stablecoin balances to card programs on Visa and Mastercard rails.
Ramp, valued at $32 billion following a $300 million funding round led by Lightspeed Venture Partners, has simultaneously introduced feeless 1:1 conversions between US dollars and USDT across its full product suite, covering USDT issued on Ethereum, Solana, and the Tether-linked Plasma network. The move brings USDT closer to fiat-like usability inside a platform whose core business is corporate expense management and payments. These developments coincide with USDT circulating supply reaching a verified all-time high of $188 billion, while USDC stands at approximately $78 billion, as the stablecoin market’s aggregate capitalisation approaches $320 billion. Binance Research has also noted that stablecoins processed $33 trillion in raw transfer volume, exceeding Visa, though a meaningful portion of that figure still reflects trading and liquidity activity rather than commerce. The directional evidence across these four data points is consistent: stablecoin settlement is entering the operational layer of global finance, and the institutions building that layer are no longer treating regulatory uncertainty as a reason to wait.
