Latest research
Introducing Refund Protocol, a model smart contract solution that brings onchain refunds and dispute resolution to stablecoin payments through non-custodial escrow. The protocol allows third-party arbiters to mediate disputes without ever taking custody of funds, enabling safer, more flexible onchain commerce.
Introducing Recibo, an innovative smart contract model that enhances ERC-20 token transactions by integrating messages functionality and gasless transfer capabilities. We show how Recibo can be used to incorporate international payment messaging standards such as ISO 20022 to address transaction documentation, regulatory compliance, and user privacy.
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.
