## What is mag3nt.?

## How it works

<Steps>
  <Step title="Fund your treasury">
    Send USDC or pathUSD to your treasury address on Base, Solana, or Tempo. Your balance is available instantly.
  </Step>

  <Step title="Issue cards">
    Create virtual payment cards backed by your treasury balance. Each card has its own spending limit, controls, and purpose.
  </Step>

  <Step title="Agents pay autonomously">
    Your agents use cards to pay for APIs via x402, AP2, or MPP protocols. Every transaction is tracked and auditable.
  </Step>

  <Step title="Automatic settlement">
    Payments settle on-chain in USDC or pathUSD automatically. 0.05% + \$0.001 per transaction.
  </Step>
</Steps>
