Simple by design

From request to payment,
with you in control.

An agent can request a payment from this page. The browser checks the temporary rules and your connected wallet asks you to approve the transfer.

01 / CONNECT◉

Connect your wallet

Use an EVM wallet on Base Sepolia. SpendFlux never receives or stores your private key.

02 / DEFINE⌘

Set temporary rules

Choose recipient addresses, a per-payment cap, and a session budget. Rules stay in memory until you close or reload.

03 / APPROVE↗

Review each payment

SpendFlux checks the request, then your wallet signs and sends it. Confirmed transfers appear on the public testnet explorer.

Browser-side controls

Check the request.
Approve the payment.

SpendFlux checks each request against the allowlist and session limits before asking your wallet to send USDC. No server, app database, or key custody is involved.
