A proof that can be replayed is a proof that can be stolen. DNA Protocol binds every proof to a nullifier registry before anchoring on the XRPL. Each proof settles once. A second submission fails at the registry and never reaches the ledger. Powered by $XDNA:

🚨 MASSIVE: DNA Protocol ZKGuard shows how the $6,300,000,000 Binance hack could have been stopped, with proof before movement on the $XRP Ledger. On October 29, the largest theft in crypto history: → ~$6,300,000,000 drained from Binance hot wallets across ~10 blockchains, most of it in about 20 minutes → Binance says no private key leaked. Its own withdrawal infrastructure signed the transfers → Blockaid traced the entry point to one successful Ethereum EIP-7702 authorization that redirected the Binance 14 hot wallet to a malicious contract → Chainalysis attributes the attack to North Korea's TraderTraitor group No key leaked. Control did. Whatever got signed, moved. One day later, DNA Protocol published ZKGuard: Proof Before Movement, an authorization architecture for exchanges and institutions designed to close exactly this gap. How ZKGuard's design answers each failure: → Preparing is not authorizing. Operations can build a transaction, but signatures are released only after a zero-knowledge proof shows the institution's policy is satisfied for that exact transaction → Approved destinations only. The proof must show the destination is in the institution's approved set. A fresh attacker address fails → Approved transaction types only. Handing a wallet's control to an outside contract is an authority change, and authority changes need their own governance approvals → Independent approvers on separate devices and credentials, each bound to that one request → Hard spending limits. Per-transfer ceilings and one shared daily allowance across every spending path → Every authorization expires and can be used once. No open-ended access → Settlement on the XRP Ledger, where native multi-signing requires a weighted quorum of independent keys Privacy stays intact. Approver lists, counterparties and internal rules stay private. Only the proof gets verified. $6,300,000,000 left because a signature was trusted without proof. ZKGuard flips the order: no proof, no signature, no movement. Part of DNA Protocol's zkPrivacy infrastructure on the XRP Ledger, all powered by $XDNA (
