TL;DR:
- COTI launched the Privacy Portal, a web app that converts public tokens into private ones with a single click on its network.
- The platform supports seven assets and fees are paid using its native token.
- The system is non-custodial, operates entirely on-chain and uses the Garbled Circuits technology developed by the protocol.
COTI launched the Privacy Portal, a web application that allows any user to convert public tokens into private tokens within the network, and reverse that operation at any chosen moment. The tool integrates directly with MetaMask through the COTI MetaMask Snap, an extension that enables the visualization of encrypted balances and the management of private tokens without leaving the wallet.
The functionality is bidirectional. The Portal In function takes a public token —such as wETH or USDT— and converts it into its private version, encrypting the balance on-chain so that only the holder can view it. The Portal Out function reverses the process: it returns the private token to its public form instantly. In both cases, private keys never leave the user’s wallet.

Privacy as Infrastructure Service
The system is backed by COTI’s Garbled Circuits, a cryptographic technology that ensures balance and transfer details remain hidden, although transactions remain auditable on the protocol’s block explorer. The AES key required to decrypt balances is generated during the initial Snap setup and is not shared with any third party.
The tokens supported at launch are COTI, Wrapped Ether (wETH), Wrapped BTC (wBTC), Tether USD (USDT), Bridged USDC (USDC.e), Wrapped ADA (wADA) and gCOTI. Once converted, they function as private ERC-20 tokens within the ecosystem and can be sent, received and interact with enabled decentralized applications.
COTI Democratizes Privacy
Fees are denominated in COTI and apply a formula that takes the greater value between a fixed fee and a percentage of the transaction amount. For Portal In, the fixed fee is 10 tokens or 0.05% of the value, with a maximum cap of 3,000 tokens. For Portal Out, the fixed fee drops to 3 tokens or 0.025%, with a maximum of 1,500 tokens. The tiered design aims to keep privacy accessible for both small transactions and institutional volumes.
Prior to the Portal’s launch, interacting with private tokens on the network required direct access to smart contracts, which limited its use to technical profiles. The new interface removes that barrier and opens the protocol’s privacy ecosystem to any user with a compatible wallet.
