Alchemy and Privy partner to simplify onchain finance

We're excited to announce a partnership between Alchemy and Privy to give developers an end-to-end stack for building seamless applications onchain.

By combining Privy's embedded wallets with Alchemy's gasless transaction infrastructure, the two platforms together make it easier than ever for developers to build onchain products that feel as simple as the best online experiences.

Meeting the UX bar for onchain finance

Onchain finance is no longer a niche. Stablecoin transaction volume hit $33 trillion in 2025, tokenized U.S. Treasuries surpassed $7 billion in AUM, led by BlackRock's BUIDL and Franklin Templeton's BENJI, and consumer fintechs are moving payments, payroll, and remittances onchain.

What each of these use cases has in common is users who expect the experience to just work. When users are moving money, every point of friction, from signup to signing a transaction, can drive drop-off and erode trust. They don't want to think about seed phrases, gas tokens, or chain IDs. They want to click a button and be done.

Delivering that experience requires solving two distinct problems: getting users onboarded quickly, and making transactions feel effortless once they're in the app. Privy and Alchemy are purpose-built to solve each side of this equation.

• Privy powers onboarding and account creation through embedded wallets, abstracting away key management and wallet setup so every user gets a secure wallet provisioned in the background.
• Alchemy powers the world’s most reliable and performant transaction infrastructure, abstracting away gas fees, signatures, and chain routing so users can complete transactions with a single click.

Together, the integrated stack takes a user from first-time signup to completing a transaction without the friction points that typically deter mainstream adoption. Users sign up with an email or social account and transact without ever managing keys, approving signature requests, creating a wallet themselves, or holding the native cryptocurrency of the chain they're transacting on.

The engineering behind making it look easy

Making onchain finance feel simple is deceptively hard. Both Privy and Alchemy have invested years of engineering into the problems that sit underneath a single button tap.

On the onboarding side, Privy's embedded wallets run on a secure key management architecture that combines hardware-isolated environments with distributed key shares, so applications can provision wallets without ever handling raw private keys. Supporting email, social, passkey, and external wallet login—then reconciling them into a single user identity with flexible custody and secure account management—requires a system that handles authentication, cryptography, and cross-device state without compromising on security or UX.

"Onchain products only feel simple when the full stack is handled end to end. Privy is excited to partner with Alchemy to bring together the account and transaction layers, so onchain products can feel as simple as the best online experiences."

— Henri Stern, CEO of Privy

On the transactions side, Alchemy has spent years building the infrastructure that powers $1B+ in gasless transactions at scale with 99.99% uptime and sub-50 ms responses. Every API call flows through real-time policy checks that enforce permissions and spend limits, cryptographic signing backed by the same hardware-level security banks rely on, and submission across every supported network—handling the very different fee mechanics of EVM and Solana along the way. Alchemy fronts the native tokens itself and bills developers in USD, so teams never have to touch a native token to ship. Having built through every major change in how protocols on different chains handle transactions, we power ~85% of gasless transactions across EVM and Solana.

The point of the partnership is that developers don't have to build any of this themselves, or stitch two stacks together by hand. The integration is designed to be a few lines of code.

Trusted by the teams building onchain finance

Alchemy powers over $4T annually for companies like Visa, Stripe, Robinhood, and more. Privy powers onboarding for leading consumer and financial apps, including Ramp, Gusto, Hyperliquid, and more. Privy currently powers over 120M accounts for more than 2,000 teams.

Teams building the next generation of products are already using Privy and Alchemy together in production:

• Slash is building financial infrastructure for modern businesses, using Privy for user onboarding and Alchemy for gasless transaction flows that let their customers move money onchain without managing gas or signing complexity.
• Gensyn, the Network for Machine Intelligence, is an open infrastructure layer for AI. It provides the foundational infrastructure AI needs to operate at scale, including compute, data, and information exchange, by enabling both humans and machines to participate in open digital markets. Built with native support for AI communication, identification, and verification, Gensyn serves as the economic backbone for continual learning over new decentralised AI models and applications, without centralised control.

"Slash exists to make financial operations seamless for modern businesses. Our customers expect money to move instantly and invisibly across borders. Privy and Alchemy gave us the infrastructure to make that happen. Regardless of having a US LLC, every user goes from signup to completed transaction reliably without a moment of complexity, and that's exactly the bar we hold ourselves to."

— Andy Jiang, Lead Product Manager of Slash

"One of the hardest problems in decentralised AI infrastructure is coordination. Getting end-users, developers, and models into open digital markets requires onboarding and transaction infrastructure that works reliably at scale. Privy and Alchemy handle that layer so our engineering focus stays on the frontier of decentralised AI, market mechanism design, and off-chain coordination at scale."

— Ben Fielding, Co-Founder & CEO of Gensyn
