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
