Privy, the Stripe-owned wallet infrastructure provider, has integrated the Uniswap API to offer native token swaps across 18 chains. The move gives developers building on Privy access to Uniswap's $4.3 trillion in cumulative liquidity with a single API call.
Privy, the wallet infrastructure platform acquired by payments giant Stripe in June 2025, has integrated the Uniswap API to deliver native token swap functionality directly within its wallet stack. The integration, announced today, means developers building on Privy can now offer asset swaps to end users without needing to manage routing logic, calldata construction, or execution mechanics themselves.
The timing matters. Privy powers over 120 million accounts across more than 2,000 teams, and sits alongside Bridge — Stripe's $1.1 billion stablecoin infrastructure acquisition — and the in-development Tempo blockchain as the core components of what is quietly becoming the most vertically integrated crypto payments stack in fintech. Adding Uniswap's swap infrastructure to that pile is not a minor feature update. It is Stripe signalling that its crypto ambitions extend well beyond stablecoin transfers.
The Uniswap API routes through a protocol that has processed over $4.3 trillion in cumulative volume across 18 blockchain networks, supports more than 10 million assets, and returns quotes in approximately 200 milliseconds. Uniswap claims the API delivers meaningful price improvement compared to leading aggregators and accesses both onchain and offchain liquidity sources. The API is free to use — no subscription fees, no per-call charges.
For developers, the practical upside is straightforward. Swaps become a native wallet capability rather than something that has to be stitched together from third-party DEX aggregators, custom smart contract interactions, and bridge protocols. A single API call handles the complexity. Privy already supports embedded wallets across EVM chains, Solana, and Bitcoin with hardware-isolated key management and SOC 2 Type II compliance — the kind of security posture enterprise clients actually require before shipping anything to production.
The broader competitive picture is worth noting. Uniswap's API is already used by MetaMask, Ledger, OKX, Fireblocks, Talos, and Anchorage Digital. Privy joining that list reinforces Uniswap's position as the default liquidity layer for wallet infrastructure providers, regardless of whether those providers sit in the retail, institutional, or enterprise segment. It also raises the question of how much DeFi functionality Stripe intends to expose through its crypto stack. If Privy now handles swaps via Uniswap, lending and yield products through additional integrations are a logical next step.
The Stripe-Privy-Bridge-Tempo architecture is starting to look less like a collection of acquisitions and more like a deliberate attempt to own the full stack from fiat on-ramp to onchain execution. Uniswap just handed them the swap layer. The only question now is how far up the DeFi stack Stripe is willing to climb.
