Sumsub joins Fireblocks and 40+ industry players to advance interoperability across digital assets
Sumsub, a leading AI-powered trust infrastructure provider for compliance operations at scale, today announced it has joined OTL (Open Transaction Layer), the open protocol initiative led by Fireblocks, alongside more than 40 members including Robinhood, Revolut and eToro. OTL will establish shared standards for on-chain identity, discovery, and transaction compliance.
The move also expands Sumsub’s collaboration with Fireblocks, building on the two companies’ partnership earlier this year to enable seamless Travel Rule compliance across the digital asset ecosystem.
As digital asset infrastructure continues to expand, businesses and service providers face increasing challenges connecting across different networks while meeting evolving compliance requirements. Today, participants often lack a common framework to discover trusted counterparties, exchange required information securely, and support compliant transactions across different platforms.
OTL aims to address this challenge by creating an open infrastructure layer that enables participants to establish verifiable identities, communicate securely, and exchange transaction related information through a shared standard. This includes compliance data such as Travel Rule information, as well as payment context and settlement coordination.
“Fragmented identity and compliance infrastructure has meant that every new integration in the digital asset industry often requires businesses to solve the same discovery and trust challenges again,” said Ilya Brovin, Chief Growth Officer at Sumsub. “OTL’s approach is focused on creating shared standards that build on existing industry practices, making it easier for organizations to connect and operate securely at scale. Having already worked with Fireblocks on Travel Rule compliance, we see OTL as an important step toward more connected and interoperable digital asset infrastructure.”
Sumsub connects more than 2,300 virtual asset service providers through the industry's largest Travel Rule network, unifying three major providers — GTR, CODE, and Sygna — into a single orchestration layer. This lets VASPs send and receive compliance data, screen counterparties, and meet regulatory requirements across networks without building separate integrations for each. That same infrastructure now extends into on-chain and reusable identity, including integrations with Chainlink's Automated Compliance Engine and Linea's Verax attestation service.
Through OTL, Sumsub will contribute to the development of identity and compliance messaging standards designed to support secure interactions between digital asset participants.
