Entity List
About this category
Institutional third-party custodians — regulated infrastructure that holds crypto assets on behalf of others, distinct from exchanges or self-custody wallet apps. Fireblocks is the flagship example, identified via a dedicated MPC co-signer detection heuristic; the category also covers custodians like Anchorage, BitGo, Copper, and Zero Hash. Split out of "infrastructure" in the June 2026 taxonomy rework.
Coverage metric
On-chain holdings (USD) across every address labeled to a custody entity, from the entity_balances_daily aggregate, latest available day.
Why this metric
Custody wallets aren’t retail activity — they’re regulated infrastructure serving hedge funds, exchanges, and enterprises. $5.6B in tracked holdings is a direct signal of how much institutional-grade custody flow Allium can see into, which is exactly the kind of "whose money is this really" question compliance and diligence teams ask.
