Privacy stopped being a niche. It became the most important narrative in crypto. And the category forming around it already has a name: Private DeFi.

TL;DR

→ Privacy is now crypto’s consensus narrative, and Private DeFi is the category taking shape around it. → Public chains expose your balances, your trades, and your strategy. That exposure carries a real cost. → Private DeFi is the DeFi you already use, with privacy built in. → It is live today: COTI Privacy Portal & private tokens → Private DEXs & COTI-powered privacy to more chains is coming soon.

Introduction

Privacy stopped being a side quest. It became the moat.

For years, privacy in crypto was treated as a feature for a narrow audience. That framing is over. a16z crypto named privacy a defining theme for 2026, and General Partner Ali Yahya argues that as blockspace becomes a commodity and raw performance converges, privacy is the advantage that builds lasting network effects and keeps users in place.

COTI has been saying this for years. The difference is that while the rest of the market is arriving at the thesis, we are already shipping the product.

Everything Moving On-Chain Shares the Same Problem

Look at where the volume and attention are going, and a pattern appears. The biggest categories in crypto are all constrained by the same thing: total transparency.

Stablecoins are the killer app, with trillions in annual settlement volume. But public balances block payroll, treasury, and B2B payments. No business broadcasts every salary and supplier payment to the world.

Perpetuals are the breakout DeFi primitive. Yet when your position size and entry price are visible to everyone, you get front-run, copied, and hunted toward your liquidation level.

Real-world assets are flooding on-chain. But institutions will not tokenize positions, counterparties, and flows in full public view.

AI agents are about to move real money on-chain. They cannot operate with their entire strategy and every transaction exposed.

Each of these is a privacy problem. COTI is the privacy answer.

It Comes Down to One Switch

Every problem above has the same fix, and it is simpler than it sounds. It comes down to a single switch that everyone understands, from a first-time trader to a global bank: Privacy Off, or Privacy On.

Privacy Off is the default on public chains. Your balances, your trades, and your strategy sit in the open for anyone to read, copy, or use against you.

COTI: Privacy On. Same assets, same apps, same wallets The difference is that balances, transfers, amounts and trades all stay private. The

What “Private DeFi” Actually Means

Private DeFi is simple to define:

DeFi you already use, plus privacy that is built in, equals Private DeFi.

This is not about hiding. It is privacy-preserving infrastructure with selective disclosure: private by default, auditable and verifiable when it must be. That distinction matters. It is privacy for people, builders, agents, and institutions, not just confidentiality for its own sake.

Private DeFi is the umbrella. Private tokens, private trading, private RWAs, and private agent activity are the proof points underneath it.

COTI Already Powers It, Today

This is the part most of the market misses. Private DeFi is not a roadmap promise on COTI. It is in production.

Privacy Portal: Drop a public token in, get a shielded one back, in one-click. Supported assets include COTI, USDT, USDC.e, wETH, wBTC, wADA, and gCOTI. This is where you turn Privacy On. 👉 https://privacy.coti.io/

Private On: Tokens. Built on Private ERC20, our independently audited, fully ERC20-compatible standard where balances stay visible only to you.

Privacy On: NFTs. The same privacy extends to private NFTs: with private ERC-721 support in the COTI MetaMask Snap, you can sync, import, and view private collectibles, identity credentials, and access tokens right inside MetaMask.

Privacy On: DEX & Pers: PriveX, the perpetuals DEX built on COTI has processed over $20 billion in trading volume and connects live AI agents. Encrypted trades are coming next.

Privacy On: Agent Skills and MCP. Live tooling that lets AI agents transact with privacy on COTI.

Privacy On: Demand: Our initiative to bring GC-privacy to leading L1s & L2s chains so any token, app, builder or project can turn privacy on.

Built for Privacy at Scale

Private DeFi only works if privacy is fast and cheap enough to actually use. That is the case for Garbled Circuits, the cryptographic protocol for multi-party computation (MPC) at the core of COTI. It runs up to 3,000x faster and 250x lighter than alternative privacy approaches, on any device, with no specialized hardware. Light and fast is what makes privacy at scale possible.

This Is the Opening

This is the start of a new chapter, for COTI and for crypto. Private DeFi is the category that will define the future of crypto and COTI is already live with real products to power it.

At COTI, we’re early to the category and the technology that will revolutionize the industry. For now, you can get started by turning Privacy On.
