COTI is a crypto coin that powers a privacy and confidentiality layer on Ethereum, enabling confidential transactions and smart contracts without leaving the Ethereum ecosystem. Built on garbled circuits and multiparty computation (MPC), COTI benchmarks show roughly 1,000 times faster computation, 100 times lower latency, and 250 times less storage than fully homomorphic encryption (FHE) systems. Compared with zero-knowledge proof-based solutions, COTI's documentation claims a more modest advantage of approximately 10× in speed and storage. It is one of only a handful of privacy solutions that employ industry-standard encryption schemes - the same standards used by governments and large banks - rather than proprietary, unproven cryptography.
At the time of writing (August 1, 2026), COTI trades near $0.01788, with a market capitalisation of roughly $52.96 million and a rank of #319 on CoinMarketCap. Beyond speculation, COTI has practical utility for enabling confidential smart contracts, powering private DeFi transactions, and securing enterprise blockchain applications. For travellers who already hold COTI or other cryptocurrencies, Epic lets you book hotels and flights, with up to 30% savings compared to Booking.com and a $25 discount on your first trip upon sign-up.

COTI at a Glance (July 2026)
What Is COTI?
COTI is a confidentiality layer that sits on top of Ethereum, enabling private transactions and data protection without breaking compatibility with Ethereum's infrastructure. It solves a fundamental limitation of public blockchains: all transactions are visible by default. While transparency is valuable for security and auditability, many use cases - from enterprise smart contracts to DeFi trading - require privacy.
The protocol uses garbled circuits, a cryptographic technique that allows computation to happen on encrypted data without exposing the data itself. This is fundamentally different from mixing services or privacy coins. With garbled circuits, a transaction is mathematically proven to be valid without revealing transaction amounts, recipient addresses, or contract logic to observers.
COTI launched as a response to enterprise and institutional demand for privacy-preserving blockchain infrastructure. Governments, banks, and corporations cannot deploy applications on fully transparent blockchains due to regulatory and competitive requirements. By providing a privacy layer secured by Ethereum itself, COTI enables these institutions to use public blockchain infrastructure without sacrificing confidentiality.
COTI was founded in 2016 by Samuel Falkon and David Assaraf, with Shahaf Bar-Geffen serving as CEO. The protocol has received audits from leading security firms including CertiK (Skynet score 88.98/100, grade AA) and Hacken. COTI currently operates a single sequencer that orders transactions and assembles blocks. Its whitepaper outlines a planned decentralized sequencer model - a shared sequencer network with proof-of-stake operator rotation and slashing - but that design has not yet been deployed.
How Does COTI Work?
COTI operates as an EVM-compatible Layer 2, meaning it runs on top of Ethereum and can execute Ethereum smart contracts. Here is how it processes a confidential transaction:
- A user submits a transaction on COTI with inputs they want to keep private (amounts, recipient, function parameters).
- The transaction is compiled into a garbled circuit - a representation of the computation in encrypted form. Garbled circuits split the computation into encrypted gates that can be evaluated without revealing the underlying data.
- Network validators process the garbled circuit without ever seeing the actual data. They verify the transaction is mathematically valid and the computation executed correctly.
- Transaction data is batched and submitted to Ethereum mainnet, with network fees covering that cost. COTI's confidentiality comes from the garbled circuits computation model rather than from zero-knowledge proofs.
- This process ensures no single point of control over transaction ordering, preventing arbitrary censorship or reordering.
The core innovation is efficiency. Traditional zero-knowledge proofs require intensive computation. Garbled circuits achieve the same privacy guarantees with orders of magnitude less computation, latency, and storage. This makes confidential transactions economical at scale.
COTI is the fuel for all confidential transactions on the network. Users pay COTI to execute private contracts. The separate gCOTI token, minted in February 2023, is used for governance voting on Treasury matters and protocol decisions. COTI node operators and community members stake tokens to support network operations.
Top 5 Ways to Use COTI Crypto Coin (COTI)
1. Book discounted hotels and flights with COTI on Epic
One of the most practical uses of COTI is booking travel through Epic. The platform has access to 2 million+ hotels and flights across more than 190 countries, and you can pay directly with COTI or 200+ other cryptocurrencies.
Book your next hotel for up to 30% less
The best part? Epic offers savings of up to 30% compared to Booking.com and Expedia on hotel and flight bookings.
New users also receive a $25 discount on their first booking. This makes Epic an easy way to use your COTI for real-world purchases.
2. Execute confidential smart contracts
Developers and enterprises use COTI to deploy smart contracts that require privacy. This includes proprietary trading algorithms that competitors cannot reverse-engineer, supply chain contracts that keep supplier information confidential, and financial applications handling sensitive client data. Because COTI is EVM-compatible, developers can take existing Ethereum smart contracts and make them confidential with minimal code changes.
3. Private DeFi transactions
DeFi protocols on COTI allow traders to swap tokens and provide liquidity without revealing their trading positions, wallet balances, or trading strategies to the public blockchain. On transparent blockchains, large trades are front-run by MEV bots. On COTI, the transaction is hidden until it is executed, protecting traders from sandwich attacks and extractive ordering.
4. Trade COTI on exchanges
COTI is listed on major centralized exchanges including Binance, Coinbase, KuCoin, and Kraken. It trades against USD and USDT pairs with 24-hour trading volume of approximately $101.49 million (as of August 1, 2026). COTI is treated as a privacy and enterprise infrastructure play by traders, so it tends to move with broader narratives around blockchain confidentiality and Web3 adoption.
5. Hold for network governance
COTI node operators and community members stake tokens to support network operations. Staking requires maintaining a 98% uptime to be eligible for rewards. Staking COTI positions you to directly support the privacy layer's infrastructure.
Is COTI a Good Investment?
Whether COTI is a good investment depends on your conviction in enterprise blockchain adoption and privacy infrastructure. The bull case is straightforward: COTI is a production Layer 2 privacy solution on Ethereum, uses proven cryptography rather than novel schemes, and serves a clear market need. Enterprises cannot deploy confidential applications on transparent chains, so demand for privacy infrastructure is structural.
The risks are equally concrete. COTI trades roughly 99% below its all-time high of $0.6826 from October 2021. The privacy layer narrative remains nascent; most of the $2+ trillion crypto market has not yet adopted privacy solutions. Competition from other privacy protocols is intensifying. Regulatory uncertainty around privacy-preserving technology remains, particularly around whether privacy chains will face compliance pressure.
The token itself is still in early development. COTI's role in the ecosystem - whether as a utility token, governance token, or fee mechanism - continues to evolve.
This is not financial advice. Crypto is volatile. Always do your own research and never invest more than you can afford to lose.
FAQs
1. Is COTI a good investment?

8. How is COTI secured?
COTI is an EVM-compatible Layer 2 secured by Ethereum itself. COTI currently operates a single sequencer; its whitepaper outlines a planned decentralized sequencer model as a future enhancement. The protocol has received audits from leading security firms including CertiK (Skynet score 88.98/100, grade AA), though that August 2021 audit covers legacy contracts rather than the current V2 privacy layer. Hacken has audited the V2 stack: an April 2025 review of the C++ garbled-circuits protocol (which raised 55 findings, including 3 critical and 20 high-severity, with 53 resolved and 2 accepted), and an August 2025 audit of the gcEVM execution layer.
