Circle Research is committed to open-source principles, making our leading research accessible to the global community. We aim to contribute to the public good and accelerate crypto, blockchain, and Web3 innovation.
Latest research
Inco Network and Circle Research introduce the Confidential ERC-20 Framework: Compliant Privacy on Public Blockchains using Fully Homomorphic Encryption (FHE). The framework transforms standard ERC-20 tokens into confidential wrapped versions that mask balances and transaction amounts, providing users with additional privacy protections while maintaining compliance controls.
Exploring ERC-7674, a proposed extension to ERC-20 tokens. Unlike existing ERC-20 approvals, ERC-7674 introduces temporary approvals which last only for a single transaction, reducing a user’s exposure to contracts they have approved.
An open-source web app prototype for interpreting and executing user intents with AI (LLMs), showcasing how plain language can be the future gateway to on-chain actions. TXT2TXN stands for text-to-transaction and uses an LLM to parse freeform English text, classify it as a type of action, and convert it into a signed intent or transaction payload to be executed on-chain.
An open-source smart contract and web app for verifying signed emails on the blockchain to protect against phishing. Chainmail serves as a public key infrastructure (PKI) to connect email addresses, PGP keys, and blockchain addresses. Users can verify email messages directly on-chain.
In conjunction with Stanford researchers, Circle Research introduces the concept of “R-Pools”, which serve as decentralized insurance for DeFi protocols by facilitating exchanges between unsettled recoverable wrapper tokens for base tokens. This work discusses two designs of such a mechanism: AMM and order book.
