Chain is a blockchain technology company originally founded in 2014 in San Francisco to build enterprise-grade infrastructure for financial services. The company developed Sequence, a ledger-as-a-service platform that enables organizations to track and transfer balances in a token format, designed for use cases in payments, lending, and asset management.

Chain's early work focused on partnerships with major financial institutions. The company collaborated with Nasdaq on a blockchain-based private market trading platform and worked with Visa, Citigroup, Capital One, and Fiserv on distributed ledger applications for capital markets. Chain raised over $40 million in venture funding from Khosla Ventures, RRE Ventures, and its strategic partners.

In 2018, Chain was acquired by Stellar Development Foundation ally Lightyear, and the combined entity was renamed Interstellar. The Chain technology and team were folded into the Stellar ecosystem. The Chain brand was later revived as an independent entity focused on blockchain infrastructure, operating the Chain Protocol and offering cloud-based ledger services for enterprises building financial products on distributed systems.
