Privacy Powered by Band: Supporting the COTI Privacy Portal Launch

TL;DR

  • Band is expanding its price feed coverage on the COTI Network with the addition of ADA, USDT, and gCOTI, building on the existing WBTC, ETH, COTI, and USDC feeds from our 2024 integration.
  • COTI Privacy Portal is now live: convert public tokens to private in one click, and back again whenever you choose.
  • The Band Unified Data Layer powers all price data powering the Portal.
  • The Portal is non-custodial, fully on-chain, and powered by COTI's Garbled Circuits technology. Supports 7 tokens: COTI, ETH, WBTC, USDT, USDC, ADA, and gCOTI.

Introduction

When Band integrated with COTI in late 2024, the goal was clear: bring reliable, decentralized price data to COTI's growing privacy-focused ecosystem. Today, that partnership takes a major step forward.

Today, we are excited to announce the expansion of our feeds’ coverage on COTI to support the launch of the COTI Privacy Portal, the simplest way for anyone to convert public tokens into private tokens on the COTI Network. Band is proud to be a core infrastructure partner, powering all price data that drives the portal’s functionality.

This is the partnership in action. It is a real product (not just infrastructure), live now, that any user with a MetaMask wallet can access at privacy.coti.io.

What is the COTI Privacy Portal?

The COTI Privacy Portal is the simplest way to take your tokens private and bring them back to the public without leaving your wallet. It gives anyone access to on-chain privacy in just one click: no technical setup, no complexity, no compromise on control. Your assets stay fully liquid and fully yours, whether they are private or public.

This opens the door to a new class of use cases, from confidential payments and private DeFi strategies to enterprise-grade privacy for supply chains and payroll, all at the fastest speed and lowest cost of any privacy protocol in the world.

The Band Unified Data Layer Powers All Price Data on the COTI Privacy Portal

Every token available in the COTI Privacy Portal, from COTI and WETH to gCOTI and WADA, has its price data served in real time by our flagship product, Band Price Feeds.

Reliable price data is foundational to any blockchain application, including the token portal. Even when balances are encrypted on-chain, accurate market pricing is needed to display values, support liquidity decisions, and enable the DeFi applications built on top of the Portal. Band's decentralized oracle infrastructure ensures this data is always available, tamper-proof, and sourced from multiple independent providers worldwide.

With the launch of the Privacy Portal, Band is expanding its feed coverage on the COTI Network to include three new price feeds: ADA, USDT, and gCOTI. This builds directly on the foundation laid in our 2024 integration, which first brought WBTC, ETH, COTI, and USDC price feeds to COTI. Together, Band now provides complete price data coverage for every asset available in the Portal.

What You Can Build

The COTI Privacy Portal is the front door to a new class of Web3 applications that combine the transparency of public blockchains with the confidentiality of encrypted computation. With Band Price Feeds underpinning every token, developers can build with confidence:

  • Private peer-to-peer transactions: send and receive tokens with encrypted balances
  • Confidential payments and private payroll: businesses can process payments without exposing amounts on-chain
  • Private DeFi strategies: execute trading and yield strategies without revealing positions
  • Supply chain settlements: settle invoices and contracts with privacy
  • Identity and asset protection: shield holdings from public visibility while maintaining auditability

Private token transfers on COTI are among the fastest and lowest-cost of any privacy protocol, a fraction of a COTI token per transfer, making these use cases practical at scale.
