On January 11, according to The Block, decentralized perpetual contract exchange Infinex announced a partnership with the Near Foundation to integrate Near's chain signature into a decentralized trading platform. Chain signature is a protocol that allows users to sign transactions on a third-party blockchain from a Near account. In a statement, Infinex said the partnership would allow users to "easily control and interact with non-smart contract chains such as Litecoin and Bitcoin". Other chains supported by chain signatures include the Cosmos chain, Dogecoin and XRP Ledger.
