Recent Success Case

Avalanche was the first network to bring Privacy-on-Demand to production. Since September 16, applications on Avalanche have been computing on confidential data, and users have been shielding AVAX and USDC through the Privacy Portal.

Expansion to further networks is a core part of the roadmap.

Privacy is becoming
a requirement.

Institutions are bringing real assets on-chain. On a public chain, every position and payment is visible to anyone, competitors included. Confidentiality is necessary before that capital can scale.

Until now, privacy meant leaving for a separate chain, and taking their capital with them. Privacy-on-Demand allows institutions to stay on yours.

How Privacy-on-Demand Works

Learn how Privacy-on-Demand runs alongside an existing chain, and what it unlocks for its ecosystem.

Video 1 of 3: What Is Privacy-on-Demand?

Privacy is becoming a requirement.

Privacy-on-Demand is creating a privacy layer for every chain. Shield, trade, and settle to pay, bid, and vote privately, without leaving the network. It is the next joint frontier in the privacy and institutional finance markets, and an embodiment of the confidentiality of finance tied with the liquidity of the chains people already use.

Privacy-on-Demand:
Features and Function

Privacy-on-Demand is built for chains and the apps on them. The fundamental purpose is to make privacy something a chain switches on, not somewhere its users have to go.

Partner with COTI

  • Garbled Circuits Engine

    Private computation runs on COTI’s garbled circuits, the fastest privacy technology in production. Data is never decrypted while it is processed.

  • No Migration

    Users, apps and liquidity stay on your chain.
    Only the private computation runs on COTI.

  • Private Balances

    Any token or stablecoin on a supported chain can enable privacy. Balances and transfer amounts stay encrypted.

  • Compliance-Ready

    Records can be shared with auditors and regulators without exposing anything else.

  • Standard EVM Tooling

    Works with ERC-20 standards and the wallets and tools developers already use.

  • Open-Source SDK

    Contracts, TypeScript helpers and tutorials, in active development on GitHub and npm.

For Developers

Add Privacy
to Any App

COTI’s PoD SDK and contracts library provide the TypeScript helpers and Solidity contracts to add private balances and confidential logic to apps on an existing chain.

Read the Docs
import { PodContract, CotiPodCrypto } from '@coti-io/pod-sdk'
 
// Your contract stays on Avalanche. The math runs on COTI.
const adder = new PodContract(address, abi, signer, {
  encryptionNetwork: 'avalanche',
})
 
const tx = await adder.encryptAndCallMethod('add', [
  { type: DataType.itUint256, value: '10' },
  { type: DataType.itUint256, value: '20' },
  { isCallBackFee: true },
], fee)
 
const [requestId] = await adder.extractRequestIds(tx.hash)
const sum = CotiPodCrypto.decrypt(result, aesKey) // 30

Frequently
Asked Questions

  • Privacy-on-Demand serves as COTI’s privacy layer for other blockchains. Users, apps and liquidity stay on their existing chain, while the private computation runs on COTI.

  • Privacy-on-Demand keeps data and balances private within a chain. Interphase moves money privately between chains.

  • Privacy-on-Demand is live on Avalanche and running on the Ethereum Sepolia testnet. It is built for any EVM chain, with more to follow.

  • No. Users, tokens and contracts stay on their existing chain. Only the private computation runs on COTI.

  • The computation runs on COTI, so the result returns in a follow-up transaction. Apps show a pending state until it arrives.

  • Each request pays a fee in the host chain’s native token. It covers both legs: sending the request to COTI, and returning the result.

  • Chains can reach the COTI team through Partner with COTI. Developers can start building today on the Avalanche Fuji and Ethereum Sepolia testnets.
