Robinhood, MetaMask, Solana join new on-chain finance standard 'OTL'

Major financial platforms including Robinhood, MetaMask, and eToro have joined the Fireblocks-led Open Transaction Layer (OTL) project, Financefeeds reported. OTL is an integrated standard layer designed to overcome the "silo" effect, where on-chain financial infrastructure operates in isolation across different institutions. The protocol will standardize identity verification, regulatory compliance checks, and transaction messaging, enabling institutions, individual wallets, and AI agents to interact securely without needing complex, bespoke integrations. The consortium currently includes payment and trading platforms such as MoonPay and SoFi, as well as major blockchain foundations like Solana, Stellar, and Polygon.
