Company profile
researched Aug 2026COTI (coti.io) develops a confidentiality layer built on Ethereum, described as fast and light, that applies the garbled circuits cryptographic protocol to protect data on a public blockchain while remaining secured by Ethereum. The stated aim is to provide a compliant approach to data protection that supports use cases such as confidential transactions, artificial intelligence, decentralized finance, and decentralized identification.
The project maintains public developer tooling, including an official Python SDK and a COTI Web3.py package, alongside an open-source examples repository (Apache-2.0 licensed) that demonstrates wallet creation, an onboarding procedure, contract deployment, and smart contract interaction on the COTI blockchain. Repository topics characterize the system as an Ethereum-related L2 focused on privacy, garbled circuits, and on-chain compute. A COTI token trades publicly and is represented by an ERC-20 contract on Ethereum.
