Arkham has introduced 'Arkham Swap', a new feature enabling direct token swaps across multiple blockchains including Ethereum, Base, BNB Chain, Polygon, and Optimism. This service aggregates quotes from various decentralized exchanges (DEXs) to enhance trade execution efficiency. Available to all Arkham users, the feature can be accessed through user accounts or the Arkham centralized exchange (CEX). Additionally, Arkham offers a $100 registration bonus, with eligibility and trading pairs subject to jurisdictional regulations.
