Toss moves money for two-thirds of South Korea. We're partnering with them to test the OP Stack as the foundation for compliant, blockchain-based digital finance infrastructure. Per @Cointelegraph: https://t.co/wxyPaqjWTH

[Optimism @Optimism]

Two-thirds of South Korea, more than 30M people, run their financial lives through Toss: banking, payments, investing, credit, taxes, all in one app.

Optimism and Toss just signed an MOU to explore putting the Won onchain.

[Privacy Boost @PrivacyBoost]

We're partnering with Toss to explore a privacy-protected Korean Won stablecoin.

Over the next 3 months, @sunnyside_io, @toss__official, and @optimism will run a PoC on blockchain infrastructure for regulated digital finance in Korea.

Sunnyside brings the privacy layer. 🧵

Privacy Boost, the first privacy offering on the OP Stack, lets enterprises integrate private transfers while maintaining auditability for compliance.

Engineered for high throughput and low latency with sub-500ms proving and 1,800+ TPS.

[Privacy Boost @PrivacyBoost]

Privacy Boost now supports preconfirmation.

Private transfers no longer have to wait for full onchain settlement before they can be used again.

If you’re building on private payments, this changes what you can ship.

We put everything about Privacy Boost into one explainer that breaks it down clearly.

How Privacy Boost helps OP Enterprise serve institutional clients ↓

OP Enterprise gives fintechs, exchanges, and financial institutions managed OP Stack infrastructure. Privacy wasn't part of the OP Stack's original design, and for institutional use cases that's a gap worth closing.

@sunnyside_io , as Optimism core developers, built Privacy Boost to close it. OP Enterprise clients get priority integration support.

What enterprises get:
• Traditional-finance-grade privacy: Sender, receiver, and amount shielded on-chain — just like traditional payment rails.
• Compliant by design: Transactions hidden from the public, fully auditable for AML and other compliance requirements.
• Drop-in SDK: No migration to a new chain. Existing finance apps can add onchain features without a rebuild.
• Finance-app performance: Fast enough that your existing users get the same experience as the services they already use.
• Self-custody: Users hold their assets directly — no platform or operator risk.

Try it on @Optimism Mainnet and @soneium .

[Privacy Boost @PrivacyBoost]

Adding private payments to your app is way easier than you think.

If you've wanted to let your users send tokens without revealing them to anyone else, Privacy Boost can enable the whole flow without having to write a single ZK circuit.

What is Institutional-Grade Blockchain Privacy?

The @FourPillarsFP report featuring @privacyboost, the first privacy solution on the OP Stack, answers this.

[Privacy Boost @PrivacyBoost]

Privacy Boost is featured in @FourPillarsFP 's deep dive on institutional-grade blockchain privacy.

A decade of privacy tech has solved parts of the problem. None has yet solved all of it on a public chain at production performance.

[Sunnyside Labs @sunnyside_io]

대박!!!

[Optimism @Optimism]

Privacy is live on the OP Stack.

Last week: drop-in SDK for confidential computing on OP Mainnet.

Now: integrating with one of the largest OP Stack chains, @soneium.

ZK + TEE. Sub-500ms proofs. High throughput. Built for real workloads.

[Startale 💿 @StartaleGroup]

Privacy first.

@StartaleApp champions users to take control of their data, powered by @sunnyside_io’s @PrivacyBoost on @soneium.

[Soneium 💿 @soneium]

Soneium ecosystem just got a major upgrade.

@sunnyside_io will bring @PrivacyBoost natively to Soneium via @StartaleApp, giving every developer access to onchain privacy from day one.

No custom builds. No trade-offs. Just privacy as infrastructure.

[Startale App @StartaleApp]

Every user should have the choice to protect their onchain activity. With @sunnyside_io, now they can.

Startale App has selected @PrivacyBoost as an Official Privacy Partner to bring onchain privacy to @soneium and everyday users.

[Privacy Boost @PrivacyBoost]

Privacy Boost is coming on @Soneium and integrating into the @StartaleApp: a SuperApp designed to bring digital assets to mainstream consumers.

As the official privacy partner of @StartaleGroup’s App, we are building consumer onchain finance as it should be.
