Developer Overview

Logia is designed to make privacy-first payments and transfers easy for developers, while staying fully compatible with the x402 protocol.

How Logia Works (5-Step Overview)

1. Deposit Funds Users deposit supported assets (USDC, ETH, ERC-20) into the Logia privacy pool. A private note is generated, containing a secret and commitment.

2. Generate Proof When making a payment or transfer, the user’s device creates a zero-knowledge proof verifying ownership and sufficient balance — without revealing their identity.

3. Submit Transaction The proof is submitted to the Logia smart contract or paymaster. The transaction is executed gaslessly if using account abstraction (ERC-4337).

4. Merchant/Receiver Payment Funds are sent from the privacy pool to the recipient. The merchant sees the payment but cannot trace the sender.

5. Change & New Note Any remaining balance is stored in a new private note, keeping all subsequent payments un-linkable.
