TL;DR

• ChainPort has integrated COTI as its 28th supported blockchain, enabling ADA and USDT liquidity to flow directly into COTI's privacy-focused ecosystem.
• ADA from Cardano can now be bridged to COTI as wrapped ADA (wADA), unlocking access to confidential DeFi, payments, and RWAs.
• USDT liquidity from nine major networks can now move into COTI, strengthening private DeFi pools and real-world asset use cases.
• The integration strengthens COTI's multichain privacy strategy, making privacy usable across chains rather than isolated.
• This move positions COTI as a serious liquidity hub for privacy-native Web3 applications heading into 2026.

For a long time, the problem wasn’t a lack of blockchains. Users held assets on one chain, liquidity lived on another, and privacy tools sat somewhere else entirely. Moving capital between them often meant slow bridges, high fees, or uncomfortable trade-offs around security and transparency. That friction showed up in real ways. Stablecoins stayed where volume already existed. ADA holders had limited options if they wanted privacy without leaving their ecosystem. And privacy-focused networks struggled with a familiar catch-22: great technology, but not enough liquidity to make it feel usable day to day.

This is where the ChainPort integration quietly changes the equation. By becoming ChainPort’s 28th supported blockchain, COTI removed a set of practical barriers that have kept users and capital apart. ADA and USDT no longer need special workarounds or isolated deployments to access privacy. They can move in directly, through infrastructure that’s already proven and widely trusted.

As announced by COTI, 

This matters because liquidity is still the limiting factor for most privacy-focused networks. But from now, Assets stay familiar, workflows stay simple, and privacy becomes something you opt into naturally rather than something you have to fight for

Why ChainPort Was the Right Choice

ChainPort is not a newcomer trying to prove itself. It is widely regarded as one of the more conservative and security-first bridges in the market. According to COTI anouncement , 

ChainPort's model focuses on controlled deployments, audited infrastructure, and reduced attack surfaces. In a landscape where bridge exploits have repeatedly drained billions, this distinction matters. The bridge is already trusted with hundreds of millions in volume and supports dozens of chains, making it a practical rather than experimental choice.

For COTI, which positions itself as an institutional-grade privacy layer, the security posture of its partner is foundational.

ADA Arrives on COTI With Privacy Utility

One of the more interesting outcomes of this integration is what it unlocks for Cardano users. Through ChainPort, ADA can now be bridged from Cardano to COTI and received as Wrapped ADA (wADA). As described in the announcement, 

This is a meaningful shift. Cardano has long focused on formal methods and cautious development, but it lacks native privacy functionality at the application layer. By bridging into COTI, ADA gains access to confidential smart contracts without sacrificing composability. This effectively turns COTI into a privacy extension for ADA rather than a competing ecosystem.

USDT Liquidity From Nine Major Networks

USDT is still the backbone of decentralized finance. Any chain aiming for real usage must attract stablecoin liquidity, not just native tokens. Through ChainPort, COTI now supports USDT bridging from Ethereum, BNB Chain, Polygon, Arbitrum, Avalanche, Optimism, Base, Chiliz, and Stratis.

COTI describes this clearly: 

This turns COTI into a convergence point for stablecoin liquidity rather than an isolated environment. Importantly, this liquidity does not just sit idle. It feeds directly into private DeFi pools, confidential payment rails, and private RWA applications. The integration supports COTI's broader architectural vision. Assets entering COTI do not lose their origin chain identity. Instead, they gain privacy functionality while remaining interoperable. This means USDT from Ethereum or Arbitrum can enter confidential DeFi environments, participate in private lending or trading, and still move back out when needed. The same applies to ADA via wADA.

COTI positions itself as "the programmable privacy layer for Web3", powered by Garbled Circuits. While the cryptography itself is complex, the outcome is simple: developers can choose what data is public and what remains confidential.

Real Use Cases That Actually Make Sense

A lot of Web3 “use cases” sound good on paper but fall apart the moment real money or real users get involved. Privacy tools are a perfect example. They often work in isolation, or only under narrow conditions, which makes them hard to justify outside of experiments. What changes with ADA and USDT flowing into COTI is that privacy stops being theoretical. It shows up exactly where people already operate.

Take stablecoins first. USDT is the backbone of on-chain finance, but it’s also completely transparent by default. Every position, transfer, and strategy is exposed. For traders, funds, or treasuries, that level of visibility is a liability. On COTI, USDT can be used inside private DeFi environments where balances and actions stay confidential while the system itself remains verifiable. That’s not about hiding activity, it’s about protecting strategy, counterparties, and sensitive financial data.

For ADA holders, the shift is just as practical. Cardano has always emphasized security and correctness, but privacy options have been limited. Wrapped ADA on COTI gives ADA holders access to confidential smart contracts without abandoning their asset or ecosystem. That opens the door to private lending, private trading, and discreet payments, all while keeping ADA as the unit of account.

Payments and remittances are another area where this matters immediately. Transparent blockchains work well for auditability, but they’re a poor fit for salaries, B2B transfers, or cross-border payments where amounts and relationships shouldn’t be public. With COTI, those flows can happen quickly and at low cost, without turning every transaction into public information.

Then there’s real-world assets. Tokenized bonds, real estate, or credit instruments don’t work if every investor position is visible on-chain. By combining USDT liquidity from multiple networks with COTI’s privacy layer, these assets can actually function the way institutions expect them to: compliant, auditable, but discreet where it counts.

None of this requires users to learn new tokens or reinvent how they operate. The assets are familiar. The workflows are familiar. The difference is that privacy is built in, not bolted on. That’s why these use cases don’t feel forced. They feel like the natural next step once liquidity and privacy finally meet in the same place.

What This Means for Developers and Builders

Liquidity is the oxygen developers need. With ADA and USDT now live, builders on COTI gain immediate access to users and capital without forcing them to abandon familiar assets. This lowers friction badly needed for this industry. Developers can focus on building applications rather than convincing users to bridge obscure tokens or accept liquidity risk. That shift alone accelerates ecosystem maturity.

Getting Started 

COTI outlines a clear onboarding flow using ADA as an example, emphasizing ease of use rather than complexity. Users connect a Cardano wallet, select ADA as the source, choose COTI as the destination, and receive wADA within minutes. This simplicity matters. Infrastructure adoption is rarely blocked by ideology. It is blocked by friction.

Looking Ahead: Privacy Goes Multichain

What this integration really signals is a shift in mindset. Privacy is no longer being treated as a special feature for niche users. It’s starting to behave like infrastructure, something that quietly works in the background while assets move freely across chains.

The multichain reality is already here. Liquidity lives on different networks. Users operate across ecosystems. For a long time, privacy broke the moment assets crossed those boundaries. COTI’s approach flips that dynamic by letting assets arrive first, then wrapping them in confidentiality without changing how people already use them.
