A deposit page shows the mempool, the queue of unconfirmed transactions on a chain, as a congestion indicator with a colour, a recommended fee rate, and an estimated time to credit, all updated every minute or so from the site’s own node or a public fee service. The page does not show the raw mempool. It translates it into the three things a player needs before pressing send: how busy the chain is, what fee to set, and how long the deposit will take.
The elements below are the ones that appear, in one form or another, on most roulette games with crypto deposit pages for Bitcoin, Litecoin, and Ethereum. Tron, Solana, and XRP pages rarely show them because their queues clear in seconds.
- Congestion level – A word or a colour, usually low, medium or high in green, amber or red. It is set by how many bytes are waiting at or above the rate that would confirm in the next block. Under a quarter of a block’s worth is low. Over two blocks’ worth is high. This is the fastest read on the page, and it is the one to check first.
- Recommended fee rate – A figure in satoshis per byte for Bitcoin and Litecoin, or gwei for Ethereum, that the site expects to confirm within its deposit target. Set your wallet’s fee to this or above, and the deposit will be credited within the estimated time. Set it below, and the deposit may sit in the queue until the chain quietens.
- Estimated time to credit – The site’s confirmation count multiplied by the average block time, plus any expected wait in the queue at the recommended rate. On a quiet Bitcoin day with a three-confirmation target, it reads around thirty minutes. On a busy day, it stretches, and some pages show a range rather than a single figure.
- Pending transactions or mempool size – Some pages show the raw figure, either as a count of transactions or in megabytes. A bitcoin mempool under five megabytes clears within a few blocks. One above fifty means hours of backlog at low rates. The number is for players who want to see the reason behind the colour.
- Last updated – A timestamp. The indicator is only as current as its last refresh, and a page left open for an hour can show a green light on a chain that turned red. Reload before you send.
- Network fee paid by – A note stating whether the site deducts a network fee from deposits. Most do not, since you pay the fee in your wallet, but a few charge for deposits on Ethereum.
Using the page takes three steps.
- Read the congestion level before opening your wallet. If it is red and the deposit is not urgent, wait or pick a coin whose page shows green.
- Copy the recommended fee rate into your wallet’s fee field, overriding the wallet’s own estimate if the two differ. The site’s figure is tuned to its own confirmation target, which the wallet does not know.
- Note the estimated time, send, and check back at that time rather than watching the page. If the deposit has not been credited by then, the queue grew after you sent, and the fee can be bumped with replace-by-fee.
The page is a reading of the chain at one moment, presented for a player rather than a node operator. Read it fresh, follow the fee it recommends, and the estimated time is the time it will take.
