How an XMR Bridge Checks Your Quote

An XMR bridge reconciles a quote by comparing the terms it showed you with the deposit it receives and the rate and fees that apply when it can complete the swap. That check determines whether the quoted amount still holds, needs an update or cannot be filled. A quote is a set of conditions for one order, not a promise that every delay or deposit change will leave the payout untouched.

The quote usually starts with the amount and asset you want to send, the asset you want to receive, and the destination address. The service estimates a conversion rate, fees and expected payout, then records details such as the deposit address and any time limit. If a swap stalls, XMR bridge options when a swap stalls covers the available paths. Knowing how quotes are checked helps you see why a status can change while funds are in transit.

What does a bridge compare with the quote?

It compares the deposit it detects with the order’s recorded terms. The service needs to match the incoming transaction to the right order, confirm the asset and network, and check the amount received. It then checks whether the deposit meets the order’s conditions, including any minimum, maximum or quote expiry.

A mismatch can change the outcome. For example, a deposit that arrives after a fixed quote expires may be priced again under the service’s rules. A smaller deposit may produce a smaller payout or need manual handling. Sending a different asset or using the wrong network can make the funds difficult or impossible for the service to process. These rules vary, so read the order details before sending.

Why can the payout change after I send?

The payout can change when the quote uses a floating rate, when a fixed quote expires, or when fees differ from the estimate. A fixed quote holds its stated rate for a set period if the order’s conditions are met. A floating quote can move with the market until the service processes the swap.

There are also costs on both sides of the exchange. The sending network may charge a transaction fee, while the receiving network may charge to deliver the output. The bridge may include its own fee or account for the cost of sourcing liquidity, meaning available funds to complete the trade. Check whether the displayed payout is before or after those deductions. Network confirmation time matters too: a transaction can be broadcast but not yet considered final enough for the service to act on.

What should I check before accepting a revised quote?

Check the revised terms against the order you created, and confirm the deposit has been matched to that order. A status such as “confirming” means the service may still be waiting for network confirmation; it does not by itself explain whether the original rate will hold. Use the order ID or swap reference when asking support about a delay.

• Confirm the sending asset and network match the order.
• Compare the amount received with the amount the quote required.
• Check the rate type, expiry time, fees and revised payout.
• Verify the destination address before approving a new transaction.

If the service cannot complete the swap on the original terms, it may offer a new quote, return the deposit or ask for more information. The available option depends on its rules and the order’s state. Do not send a second deposit just to make an amount match until the service confirms in its official order page or support channel how it will handle the first one.

The practical rule is simple: save the quote and order reference, then compare any change with the recorded terms before taking another step. That gives you a clear basis to decide whether to accept a new payout or ask the service to explain the difference.
