No, the address is the key

A classical Algorand address is the 32-byte Ed25519 public key itself with a 4-byte checksum, base32 encoded, so the key is public from the moment an account is funded and never hidden. Exposure is therefore total by construction for Ed25519 accounts; only accounts whose authoriser is a Falcon key (via rekey or a native Falcon account) are not exposed.

Quantum-safe path
Available

Live. Two paths exist. (1) Falcon LogicSig accounts: the AVM gained a falcon_verify opcode and the first post-quantum transaction on MainNet was executed on 3 November 2025 (Falcon-1024, about 1,280-byte signatures, about 1,793-byte public keys); an existing account can rekey to a Falcon-controlled LogicSig authoriser and keep its address (Algorand Post-Quantum Ledger, 14 May 2026). (2) Native Falcon-1024 accounts: delivered in the v5.0.0 protocol upgrade, which passed the approval threshold on 15 August 2026 and activated on MainNet after the mandatory 208,000-round (about 7 day) cooldown; Falcon-1024 accounts no longer need a LogicSig wrapper, derive from the usual 25-word mnemonic, and are supported by the SDKs, AlgoKit and Pera Wallet. Falcon-512 support is planned for end of 2026, multi-scheme multisig for end of 2026, and the Foundation targets broad quantum resilience by end of 2027.

Scan of every account holding more than 1,000 ALGO; smaller accounts are not classified. Shares are of all scanned ALGO, including Unknown and Contract, so Exposed plus Quantum-safe does not sum to 100%. USD is that ALGO at the current price, not a share of market cap. Status is the key type of the last signed transaction. Never-signed and idle rekeyed accounts read Unknown. Balances are read over a scan of several minutes.
