# Fireblocks

*Institutional custody named in the chain's ecosystem — and an OTL co-founder.*

Fireblocks is the institutional-custody name most associated with Robinhood Chain's launch, but the evidence is a step softer than for its peer BitGo, and it is worth being precise about that. What is well-supported is the standards work: Fireblocks co-founded the Open Transaction Layer (OTL) with Robinhood and MetaMask, a multi-company coordination standard for identity, messaging and transaction coordination across regulated institutions, non-custodial wallets and AI systems. That places Fireblocks in the inner ring of the chain's institutional design, not the periphery. What is less firmly evidenced in primary sources is a dated, Fireblocks-authored 'we now custody Robinhood Chain assets' announcement of the kind BitGo published on day one. The briefing and Robinhood's ecosystem framing list Fireblocks among custody partners, and Fireblocks is one of the two or three default MPC custodians institutions reach for, so support is entirely plausible and consistent — but this dossier deliberately does not assert a day-one custody launch as fact until a first-party notice confirms it. The position to take: treat Fireblocks as a confirmed OTL co-architect and a listed custody partner whose specific Robinhood Chain custody product and go-live date are the open items, and confirm current asset support with Fireblocks directly before relying on it. This is the responsible framing for an institution making a custody decision, where 'probably supported' is not good enough.
