If your deposit is below the quoted minimum, wait until you can meet it or choose a route with a lower threshold. A swap service may be unable to process an under-minimum deposit, even if the transaction reaches its wallet. For the separate question of how XMR bridge handles treasury transfers, that guide covers the larger transfer flow; here, the key issue is whether a small deposit can enter the swap at all.
Send enough to meet the minimum after costs
The minimum is the smallest amount the service says it can process for that quoted swap. It can vary by the asset pair, network, market price, and costs of moving or exchanging the funds. Check the quote again just before sending.
Compare the minimum with the amount the service will receive, not just the balance you plan to spend. Network fees are charges for sending a transaction; depending on the chain, they may come out of the amount sent or be paid separately. Leave a buffer if the quote says the received amount must meet a threshold.
For example, if an illustrative quote sets a $50 minimum, a $49 deposit may fail the threshold. If your wallet can send $50 but a sending fee comes out of that amount, the service may receive less than $50. The actual minimum and fee depend on the quote and chain.
This route suits someone who can add funds and wants the swap processed normally. It does not fit a balance that cannot reach the threshold after costs. An XMR bridge routes an exchange between Monero and another chain, but it cannot make a too-small incoming amount meet the service’s minimum.
After an under-minimum deposit, check the service’s recovery rule
A confirmed deposit can still be too small to swap. Services may handle this differently: some may wait for more funds, while others may require a recovery request or be unable to return the deposit automatically. Do not assume another transfer will be added to the first one; the service may treat each quote as a separate order.
Before sending, look for the stated rule for deposits below the minimum, including whether later deposits can be combined and whether a return can cost a network fee. A refund, if offered, may take time and return less than the original amount after transaction costs. Keep the quote details and transaction ID, the public reference used to find a payment on a blockchain.
This option fits only when the service explains how it can recover the funds and you accept any cost or delay. If the policy is unclear, contact the service before sending. For a small balance, choosing a route whose current minimum you can meet is usually the simpler choice.
