Privacy becomes more powerful across chains. Build applications that compose protocols across chains through Aztec's privacy layer to discover entirely new use cases that only work when privacy is composable across ecosystems. Leverage our bridge partners (Holonym, Substance Labs, Train, Wormhole and more) to create cross-chain experiences that weren't possible before.

Only with native privacy can identity infrastructure work on-chain, because sensitive information simply cannot be exposed. Build on Aztec to create identity systems where people host credentials, attestations, or identity data that they can leverage across applications, whether on Aztec itself or composed cross-chain. This could be credential systems, DID infrastructure, verification mechanisms, aggregated attestations from multiple sources (like combining OpenBanking.nr and ZKPassport), or novel ways to prove facts about yourself without exposing everything.

Privacy unlocks a design space we haven't fully explored yet. We know there are applications that become possible with native privacy that we haven't seen before. Build the thing that makes us say 'oh wow, that's why privacy matters.' This could be gaming mechanics, governance systems, DeFi patterns we haven't seen, confidential business logic, or something we haven't thought of. The constraint is: it should only be possible because Aztec has native privacy.
