Introduction to Starkware and EY’s Nightfall Integration
If you’ve been keeping an eye on the zero-knowledge space, you already know that Starkware is more than just another infrastructure company. The company has always pushed the limits of what can be done with validity proofs. StarkEx powers some of the biggest scaling projects, and Starknet is a permissionless zk-rollup. They have always had a simple goal: to make decentralized finance faster, cheaper, and big enough to be used in the real world.
Now, they’re working on another big issue: privacy.
It’s a big step forward that EY’s Nightfall protocol is now part of Starknet. Nightfall is an open-source zero-knowledge privacy layer that was first made to keep Ethereum transactions private. By combining it with Starknet’s scalability engine, the two are basically making a shared privacy primitive that both businesses and regular people can use.
What happened? Private transactions that don’t give up the openness and ability to audit that make blockchain useful in the first place.
At first glance, this announcement might not seem like a big deal, but it is. We’re moving into a time when protecting data isn’t just a nice thing to do; it’s required, expected, and becoming less and less negotiable for businesses. Banks, asset managers, and big companies can’t do business in public without giving away their plans, putting clients at risk, or breaking the rules.
Starkware and EY are saying that this integration will be the basis for a whole new type of DeFi app that will have institutional-level privacy built in from the start.

Why Institutions Should Care About Private Payments
Let’s be honest: the “everything on-chain and public” model works for some situations, but most banks won’t use it. It’s not just awkward for a bank to let competitors or criminals see its transaction history; it’s also a risk.
Now that Nightfall is available on Starknet, businesses can finally make B2B payments, manage their money, and settle debts across borders without letting the whole world see their private information.
It’s not just the privacy layer that makes this interesting; it’s what it lets you do.
- You can manage treasuries in private.
- People can trade tokenized assets without letting everyone know about every move.
- And since the underlying zk-proofs still let people choose what to share, audit trails are still available for regulators when they need them.
There’s also the DeFi side.
For years, institutions have been carefully watching decentralized finance, but the lack of privacy has kept most of them from getting involved. Things are starting to change. Companies can start using lending protocols, yield strategies, and liquidity pools without letting anyone know what their positions and strategies are.
It’s the best of both worlds: you can use efficient, programmable finance without having to worry about being seen.
Confidentiality and Compliance Go Hand in Hand
Privacy and compliance in crypto have never really gotten along. If something is too opaque, it will get the attention of regulators. If it is too clear, it will keep institutions away.
The Starknet–Nightfall integration tries to find a smart middle ground.
EY has a lot of experience dealing with rules and regulations, and that shows in how the framework handles KYC and identity. The system doesn’t make users choose between privacy and compliance; instead, it lets them selectively disclose information. Users can prove what they need to without giving away everything.
A regulator or counterparty can check that a deal follows the rules without knowing everything about it. That’s a small but important change.
It also means that organizations don’t have to choose between using public blockchains and following the law. There is no need to add the compliance layer later; it is already built in.
This is exactly the kind of progress that banks and businesses that have been waiting for permissioned-like guardrails in a permissionless environment need.

Where Starknet Is Now and What Comes Next
Let’s not sugarcoat it: Starknet has had some problems as it has grown. Past outages have made people question the reliability of the service, and in a field where uptime is important, those worries can’t be ignored.
That being said, the network’s growth tells a different story. The total value locked has been going up steadily, and developers are still very active. People are building on Starknet because the technology works really well when it does.
The Nightfall integration is part of a broader push to make the network not just scalable, but enterprise-ready. The rollout will happen in stages, which will give the team time to improve both the privacy and performance features as more people use them.
That kind of careful pacing is important for businesses that are looking into ways to get into production-grade blockchain infrastructure.
In the future, we will need to keep our attention on two things: reliability and throughput. Starknet’s architecture can already handle a lot of transactions, but if institutional inflows happen, the network will need to show that it can handle high demand without breaking down.
