FAQ

Gen Z is tired of the “diamond markup” story—paying extra for brand premiums and old-school marketing, plus the environmental and transparency concerns. VowVault is a different model: your commitment is verified on-chain (signed by both partners) and the value is anchored in assets, while the ring is simply the symbol and design you love. No diamond tax—just a clearer, more intentional way to commit.

In production, we would read the contract state to confirm it meets published requirements (both signers, amount threshold, supported network).

No. The long-term plan is a guided “contract creation” flow. For now, we’re validating demand and preferences.
