Onchain and Offchain: Closing the stablecoin compliance gap

Enter your information to view this webinar

About this session

Once a niche crypto trading tool, stablecoins are increasingly being used to facilitate global payments and money movement. As mainstream adoption increases, compliance programs are being rebuilt to fit the needs of this new rail. The frameworks are familiar from traditional finance, but stablecoins have different mechanics. Blockchain transactions settle in near real-time, are often irreversible, and are public and traceable. 

This combination raises novel operational questions. How do you design Know Your Customer (KYC) and Know Your Business (KYB) procedures to fit onchain programs? What does transaction monitoring look like when you’re dealing in stablecoins? How do stablecoin rails make it easier to monitor and trace sources of funds? 

In this webinar, Castellum.AI CEO and Co-founder Peter Piatresky sits down with some of the compliance and policy leaders that are answering these questions. Tyler Nielsen, Head of OFAC and Sanctions Compliance at Rain, Tom Armstrong, Head of Compliance Advisory at TRM Labs, and Lesley Chavkin, Head of Global Public Policy at Ribbit Capital, explain what an effective compliance program looks like when the assets are onchain. 

Watch on-demand to learn more about: 

  • How asset freezes and seizures work on the blockchain, and the different playbooks stablecoin issuers follow 
  • Why compliance screening needs to happen not only before transactions are initiated, but also after in continuous monitoring programs 
  • What the newly-passed GENIUS Act in the US means for stablecoin issuers and payment processors  
  • How autonomous actors and agentic commerce will impact KYC and KYB procedures and what needs to evolve
