ZERA ZERA

ZERA is a zero-knowledge (ZK) privacy protocol on Solana that enables shielded balances, private transfers, and offline-capable peer-to-peer exchange for existing crypto assets (e.g., USDC, USDT, SOL + more). The project is developed by Zera Labs with the goal of providing cash-like privacy while remaining non-custodial and compatible with existing stablecoin rails.

At the protocol level, users deposit supported assets directly into the protocol and receive “cryptographic notes.” These notes can be transferred privately without the need for an internet connection and later withdrawn back to the same underlying asset. The direct-deposit architecture creates an unified, asset-agnostic anonymity set with clean composability for wallets, relayers, and dApps - without wrapped assets or AMM routing

ZERA is a value-accrual token tied to protocol activity. Its design centers on usage-driven, programmatic burns (i.e., a fraction of protocol volume triggers token burns executed by the program). This mechanism ties token supply reduction directly to adoption, while avoiding direct fees on private transactions.

This approach is intended to align stakeholders with protocol growth while minimizing regulatory complexity associated with fee collection or custody.

ZERA’s core privacy layer is built on well-studied primitives:

• Commitments & Nullifiers: Values are committed using Pedersen commitments; unique nullifiers prevent double-spends while keeping linkability hidden.
• Zero-Knowledge Proofs: Transactions are proven with succinct zk-SNARKs (e.g., Groth16) so validators verify correctness without learning senders, receivers, or amounts.
• Unified Pool: All notes share a common anonymity set. Optional relayers can submit withdrawals for users, helping further break the link between their network activity and identity.

The protocol is non-custodial; users retain control of their keys and notes. Because deposits/withdrawals map to the same underlying assets, accounting remains transparent at the reserve level while individual transfers stay private.
