Zcash developers propose per-swap keys to keep NEAR Intents ZEC trades private from future quantum attacks
The Zakura team wants each swap executed via NEAR Intents to use a unique key so a refund address on NEAR’s public chain cannot be used to link a user’s broader payment history.
On Oct. 19, 2026, developers associated with Zcash announced a proposed change intended to protect ZEC swaps routed through NEAR Intents from potential future quantum‑computer attacks.
The change, put forward by the team behind Zakura, would assign a distinct cryptographic key to every individual swap made via NEAR Intents. Under the current arrangement, a refund address tied to a swap can appear on NEAR’s public chain; the Zakura proposal aims to prevent that single published refund address from serving as a link to a user’s wider ZEC payment history if quantum advances undermine existing key material.
The proposal focuses on per‑swap key generation as the material detail of the fix. By ensuring each swap uses its own key, the Zakura team says a refund address left on NEAR’s public ledger would not reveal connections between separate payments.
Brief background
NEAR Intents is the mechanism referenced in the proposal; swaps executed through it can result in a refund address being recorded on NEAR’s public chain. The Zakura team framed the per‑swap key approach specifically as a safeguard against the long‑term risk posed by future quantum computers that might be able to compromise reused or linkable keys.
WHY THIS MATTERS
ANALYSISIf implemented, per‑swap keys would reduce the risk that a single on‑chain refund address could be used in the future to correlate multiple ZEC swaps and reconstruct a user’s payment history. That lowers the chance of retroactive deanonymization should quantum advances weaken cryptographic primitives relied on today. The change would be a forward‑looking privacy engineering measure, but it depends on adoption and integration into the relevant implementations of Zakura and NEAR Intents; those steps, and their timeline, are not established in the proposal itself.
