Stablecoins moved over $35 trillion in 2025. Less than 1% of that volume was actual real-world payments. The rest was trading, treasury operations, and capital movement that happened to use stablecoin rails. Tempo is built on the bet that the missing 99% (the payment volume) is the largest opportunity in crypto, and that capturing it requires a chain designed around payments instead of one retrofitted from a DeFi platform.
Tempo went live on March 18, 2026, incubated by Stripe and Paradigm. Across was a day-one bridge partner, supporting USDC transfers from any major EVM chain to Tempo through the same intent-based architecture that's processed $36+ billion in volume without a single security exploit.
Here's what Tempo is, why a payments-first chain is structurally different, and how to bridge in.
What Tempo Is
Tempo is a Layer 1 blockchain built for real-world payments at scale, designed for instant settlement, predictable low fees, high throughput, and global availability. It's not chasing TVL or yield farming. It's payment infrastructure, with a stack purpose-built around the requirements of payment workloads:
Stablecoin-native gas. You pay transaction fees in stablecoins. There's no native token to buy first, no volatile gas asset to manage.
Instant, deterministic finality. Designed for payment flows that need predictable settlement, not eventual consistency.
Dedicated payment lanes. Throughput allocated specifically to payment workloads instead of competing with DeFi or NFT activity for blockspace.
Built-in stable asset DEX. Native stablecoin liquidity without depending on third-party AMMs.
Machine Payments Protocol (MPP). A native open standard for machine-to-machine and agent-to-agent payments, co-authored by Stripe and Tempo.
The mainnet launch was paired with the public release of MPP, an open standard for autonomous agent payments. The protocol's first applications include sessions ("OAuth for money," in Tempo's own framing) that let agents authorize a payment limit upfront and then stream small payments continuously without requiring a separate transaction for each interaction.
Why a Payments-First Chain Matters
Most blockchains were built for trading or general-purpose smart contracts and then bolted on payment use cases later. Tempo inverts that. The chain's design assumes:
Payments are high-frequency and small-value, so transaction costs need to be predictable and low
Payment systems need deterministic finality, not "probably finalized in a few seconds"
Payment users don't want to manage a volatile gas asset just to transact in dollars
Payment infrastructure has to scale without congesting on someone else's NFT mint
The implication: Tempo doesn't compete with Ethereum or Solana for DeFi mindshare. It competes with SWIFT, Visa, and bank wire infrastructure for actual payment volume.
The launch partner list reflects that positioning. Tempo's mainnet shipped with design partners including Visa, Mastercard, Deutsche Bank, Standard Chartered, Revolut, Nubank, Shopify, OpenAI, Anthropic, Ramp, and DoorDash. When you read that list, it's clear what Stripe and Paradigm are after. This isn't a chain trying to bootstrap a DeFi ecosystem. It's a chain trying to be the settlement layer for payment companies that already exist at scale.
The Machine Payments Protocol Is the Real Story
The MPP launch is what makes Tempo's positioning sharp. Co-authored by Stripe and Tempo, MPP is an open standard that lets software agents (AI systems, automated workflows, etc.) request, authorize, and settle payments programmatically without human intermediaries.
The use cases are concrete: a research agent paying for dataset access, a development agent purchasing compute or testing infrastructure, a workflow agent coordinating dozens of services and paying each one as it completes a task. Most of these involve hundreds of small payments per workflow, which traditional payment rails can't handle economically and most blockchains can't handle technically.
Sessions are the primitive that makes this work. An agent opens a session, sets aside funds upfront, and consumes resources from services with payments streaming continuously. Thousands of small transactions get aggregated into a single settlement transaction onchain, making true pay-per-use viable at internet scale.
The MPP payments directory already includes more than 100 services, including Alchemy, Dune Analytics, Merit Systems, and Parallel Web Systems. Visa has extended MPP for card-based payments. Stripe has extended it for cards, wallets, and other payment methods. Lightspark has extended it for Bitcoin Lightning. The protocol is rail-agnostic by design.
If agentic commerce develops the way Stripe, OpenAI, and Anthropic seem to think it will, MPP becomes the standard infrastructure layer underneath. That's a much bigger market than DeFi.
How to Bridge to Tempo With Across
Across is live on Tempo from day one. The integration supports three core flows:
Bridge USDC from any major EVM chain (Ethereum, Arbitrum, Base, Optimism, Polygon, and others) to Tempo
Bridge USDC back from Tempo to any major EVM chain
Swap USDC for pathUSD on Tempo, or vice versa
The flow is the same as any Across bridge:
Open app.across.to/tempo
Pick your source chain and select USDC
Pick Tempo as the destination
Confirm
Funds arrive in seconds. The relayer fronts the capital on Tempo, you take on zero finality risk, and the relayer gets reimbursed once the source-chain deposit settles.
For developers building on Tempo who want to embed bridging directly into their app, Across exposes the Swap API and Across+ integration options through docs.across.to.
Why Across Is the Right Bridge for Tempo
A payments chain is only useful if liquidity can move into it without friction. Stripe and Paradigm clearly thought hard about which interoperability layer to integrate at launch, and the choice of Across reflects what payment-focused infrastructure actually needs:
Speed matters more for payments than anything. A payment that takes minutes to bridge in feels broken. Across's intent-based architecture delivers funds in seconds, which keeps Tempo's payment UX consistent end-to-end.
Predictable fees. Tempo's pitch is predictable, low cost. A bridge with volatile fees breaks that promise on the entry path. Across's relayer-competition model keeps fees consistently among the lowest in the industry.
Security at scale. Enterprise users evaluating Tempo will ask one question about every piece of infrastructure they touch: has it been hacked? Across's answer is no. Not once, across $36+ billion in volume. That's the kind of track record institutional capital actually requires.
Stablecoin-native. Tempo is a stablecoin chain. Across is a stablecoin bridge. The fit is mechanical: both are designed around moving dollars fast and cheaply, which is why integrating Across at mainnet was the obvious choice.
What Tempo Means for Crypto Infrastructure
Tempo isn't a DeFi chain trying to become a payments chain. It's a payments chain that happens to use blockchain rails. That's a meaningful distinction.
If the chain's launch partners actually deploy production payment volume on Tempo (a question that takes 12-18 months to answer), the implications cascade. Stablecoin issuers need to integrate. Compliance providers need to onboard. Bridge infrastructure needs to support enterprise-grade reliability. Each of those is a separate market opportunity.
Across is positioned at the bridging layer. Being integrated with Tempo at launch means Across is becoming the interoperability layer not just for DeFi, but for real-world payments infrastructure. That's a market orders of magnitude larger than DeFi alone.
For users moving capital into Tempo today, the path is direct. Bridge USDC through Across, arrive on Tempo in seconds, and start interacting with the chain's payment-native ecosystem.
Bridge to Tempo With Across
Tempo is the payments chain Stripe and Paradigm built for the next generation of internet money movement. Across is the bridge that gets you there in seconds, with zero security exploits and the lowest fees in the industry.
The infrastructure for stablecoin payments at scale is finally getting built. Tempo is one of the chains making the bet. Across is the rail that connects everything else to it.
