What you deposit over x402 sits in the x402 escrow, not with us. A refund returns what you have not spent.
When you pay by an MPP session, your deposit sits in the session escrow at 0x5e09aD70b644414cD1cD7Df1d9a10fF7899D92B8, a separate contract from the x402 escrow, and it pays the split through the payee 0x715721CB50E9e70b8044A45B0385e4eB7812a6c4. The session escrow was deployed by ZEAM, has no owner or administrator, and is not audited: nobody outside its authors has reviewed it. The unspent part of a session's deposit comes back when you close the session, in the same transaction. The ZEAM relay sends the close, or your signed exit, and you need no ETH. It pays the gas of a close when what the session spent covers the gas of opening it, of any top-up or close request the relay sent and of the close, plus 15%, and of an exit when what the session has settled covers the gas of opening it, of any top-up or close request the relay sent and of the exit, plus 15%; otherwise an MPP session pays that gas in USDC out of what returns, as an x402 refund does. You can also leave without us: requestClose on the session escrow, then withdraw after its grace period, the only way out of a session that needs ETH on Base for gas.
