1/3 Introducing xSHADE: the privacy layer for the agent economy.

xSHADE extends x402 with cryptographically derived one-time payment addresses, so agents and APIs can receive on-chain payments without exposing a persistent wallet.

xSHADE isn’t a mixer.

There’s no shared pool and no custodian.

xSHADE uses secp256k1 key agreement to let sender and receiver independently derive the same one-time payment address.

3/3 xSHADE doesn’t replace x402. It makes it private.

To the payer, it’s still a normal x402 payment.

Under the hood, every payment resolves to a fresh address, breaking the persistent link between an agent and its on-chain revenue.

The agent economy is now finally private.

2/3 Privacy shouldn’t require giving up custody.

With xSHADE, the server only needs a public key. Spend authority stays entirely with the receiver.

No custodial hot wallet sitting behind the API.

Public agents. Private settlement.

The next layer of x402 is privacy.
