BitGo, a major institutional digital asset custodian, has added support for Arbitrum’s native governance token ARB, allowing institutional clients to custody ARB using BitGo’s Hot, Custodial, and Self-Managed Cold wallets. According to BitGo’s announcement, this integration extends its existing Arbitrum coverage (it already supported Arbitrum-based ETH, or “arbeth”) and is positioned as part of BitGo’s broader effort to support leading Layer 2 ecosystems. Third‑party coverage notes that ARB support is now available across BitGo’s wallet stack, which targets regulated and institutional users seeking secure storage and operational tooling for the token. The move matters because Arbitrum is one of the largest Ethereum Layer 2 networks, using optimistic rollups to provide cheaper and faster transactions while settling to Ethereum mainnet. Its ARB token is an ERC‑20 governance asset used within the Arbitrum ecosystem and the Arbitrum DAO, giving holders voting rights over protocol decisions and funding programs. By enabling institutional-grade custody for ARB, BitGo lowers operational and compliance barriers for funds, trading firms, and other professional market participants that want exposure to Arbitrum’s governance and ecosystem while adhering to institutional security and reporting standards. This kind of custodial support is often a prerequisite for broader institutional participation in a network’s governance token and can facilitate deeper liquidity and more sophisticated financial products built around ARB.

DATs aren’t “the next LUNA,” but unwind risks exist. With little leverage, forced selling is unlikely, yet arb incentives grow if mNAV drops. Outcomes depend on how concentrated holdings are—few big players dampen risk, many big DATs amplify it.
