Proof-Powered

Private Payments

Native privacy layer

Native Privacy Layer – Wallet data, balances, and identities are protected with zk proofs — no need for separate privacy tokens. - x402 Automation

Proof-based transactions

Proof-based Transactions – Each transaction is verified through cryptographic proofs instead of third-party trust

x402 automation

Payments and dApp access are processed automatically through the x402 layer, without manual confirmation

On-chain verifiability

On-chain Verifiability – Anyone can verify the proof on-chain without seeing the underlying transaction details
