Coinbase can take value out of reach today only on Algorand. Why and how.

The path to quantum-safe today
- Algorand holdings: rekey each account to a Falcon-1024 authorizer. The address stays the same, no funds move, nothing changes for customers.
- Assets issued on Algorand: rotate the manager, reserve, freeze and clawback addresses to Falcon accounts.
- Other chains: no live path yet. Keys that have never signed stay Not yet exposed until they spend; moving them to fresh keys resets the clock. Threat model
About these labels
Every address above carries its source. "Published by the entity" means the entity itself listed the address (proof of reserves, transparency page, official docs). "Explorer label" means a public block explorer attributes it. Nothing here is inferred by us. If a label is wrong, dispute it and it is hidden within one business day while we check.
Coinbase publishes audited financials rather than wallet addresses, so DefiLlama does not track its reserves; it is included because of its size. Entries rely on Etherscan name tags.
