# How It Works

> The inflow, bridging and allocation flow for USDC cash

The flow has three steps, and none of them requires the company to change custodians.

<Steps>
  <Step title="Native USDC on Ethereum">
    Cash stays in self-custody or with the qualified custodian the company already uses.
  </Step>

  <Step title="Circle CCTP">
    Cross-network movement happens through native burning and reminting of USDC, with no third-party bridge and no wrapped token.
  </Step>

  <Step title="Approved allocation">
    The balance is distributed across the tokenized Treasuries defined in the company's allocation policy.
  </Step>
</Steps>

```

Rebalancing happens only with your approval: TESA monitors the rate spread between the assets and proposes the adjustment, which is executed only after it is approved and signed by your custodian. Redemptions run on the same rail in reverse, with daily liquidity.
