[Philipp Zentner | LI.FI @PhilippZentner]

Two years ago, we started with a simple question. What will it take to simplify the integration of blockchain primitives with global financial rails?

Today we’re launching LI.​FI Intents to help make that possible for every business in the world.

A product we know this industry needs, a product we’ve built to solve some of the biggest challenges global fintechs face as they move into digital assets, a product we believe companies don’t need tomorrow, or even today, they needed it yesterday.

How do we enable stablecoin payments?
How do we unlock access to real-world assets for our users?
How do we ensure we only touch compliant liquidity across blockchains?

These are some of the biggest questions leadership teams across fintech are asking themselves right now.

They’re the same questions we asked ourselves. And we knew they had to be solved.

LI.​FI Intents is our answer.

Every touchpoint of the stack is modular. The entire product is fully customizable to fit ANY business need.

From the order type, to who the market maker can be, to how the transaction will be settled on blockchains, to which service providers your business trusts - everything can be shaped around how you want your product to work.

As a builder myself, this is the kind of flexibility and abstraction I’ve been looking for in this industry ever since we started LI.​FI 5 years ago.

And I’m incredibly proud that the LI.​FI team is delivering it.

LI.​FI Intents is built to make crypto products easier to launch for businesses that want to move onchain, but have been slowed down by the complexity of it all.

The enterprise stack for onchain finance.

For all intents and purposes.

Session 1 - FHE & Confidential Smart Contracts
@poppyseedDev (Aurora Poppyseed), DevRel at @zama, breaks down how Fully Homomorphic Encryption (FHE) is bringing real confidentiality to the EVM - running computations on encrypted data without ever decrypting it.
From private transfers to blind auctions, this is what on-chain privacy actually looks like.

Session 2 - TimeLock Recovery for Bitcoin Backup
@oren_z0 (Oren Zomer), Founder at @RitrekRecovery, walks through structured wallet recovery using Bitcoin Script - primary to secondary wallet, and what BIP-128 makes possible.
Self-sovereign custody, done right.
Two of the most technically dense topics in crypto infrastructure - in one session.
Whether you're building on EVM or working with Bitcoin Script, this one's for you.

@PhilippZentner More great news!

[Brian Armstrong @brian_armstrong]

Some of our best hires were totally unqualified on paper.

They always had the same qualities: entrepreneurial, high agency, smart, mission aligned, and they got shit done.

If you’re hiring, especially in early stages, seek out & bet on these people. Don’t over-index on resumes.

@jacob_posel Only if it name Goy

[Ligero Inc. @ligero_inc]

Payroll is one of the most sensitive operations in enterprise finance. Today, we're bringing it on-chain, without compromising privacy or compliance.

Ligero is live as an L2 on @EspressoSys, with on-chain payroll as our first production use case.

We didn't build around the problems enterprises face, we solved them. Private salaries, instant stablecoin settlement, and regulatory compliance that's cryptographically guaranteed, not manually managed. And it all works within the tools and workflows your teams already use.

Espresso is running it for their own employees, validating the system in a real, high-stakes environment. That's proof, not a promise.
