Field notes
Five checks before a Monad swap is worth signing
Speed does not improve a bad quote. The chain will fill a terrible price in two slots and bill you for the limit. These are the checks that still matter when the block is faster than your eye.

A swap is a contract call with a recipient, a minimum, and a gas limit. Everything else on the screen is decoration. On a 300 millisecond chain the decoration updates more often, which makes it easier to trust and not more true. The five checks below are the ones that change whether the receipt is a trade or a donation. They are the same checks a careful Ethereum desk already uses. Monad changes the cost of skipping them, because the fill and the bill both arrive before you can cancel.
Who is paid, and what is the least you will accept
The recipient on a router call is an address, not a nickname. For a vault it must be the vault. For a wallet it must be the wallet. A call whose recipient is the router, or a forwarder you do not recognise, can be a successful receipt that pays someone else. The minimum output is the number the contract will refuse to go below. Zero, or a figure far under the quote, means you have agreed to any price that still moves. MONAF’s desk will not sign a zero minimum, and it asks a second node to agree the quote within a band before that minimum is set. You can do the same with two RPC hosts from the public list. If they disagree, you do not have a price. You have an argument.
The limit, and the address behind the ticker
The gas limit is the fourth check and it is Monad-specific in a way the first three are not. Because the chain bills the limit, a swap that is fine at 200,000 gas is a different trade at 2,000,000. Run the multiplication in the previous piece before you approve the sheet. The fifth check is the contract. WETH, WBTC, and a stablecoin ticker are labels. The thing you trade is a 20-byte address. The desk’s own book names the addresses it will touch, and it refuses a round trip that does not clear its cost at the size you asked for. A pool can print volume and still be too thin for your size. Volume is the past. The quote at your size is the trade.
Two nodes, one minimum, one recipient, one limit you can justify, one address you looked up. Then sign.
Where the inventory is, today
CertiK’s note of 20 October 2026 put about 47 percent of thirty-day DEX volume at Kuru, on a tape of about $2.64 billion. That is a routing fact from one researcher on one date. It means a quote that never asks Kuru is ignoring half the printed tape, and it means a day Kuru is down is not saved by the existence of Uniswap and PancakeSwap. Ask the venue you are about to use for the output at your size. Then ask a second one. The chain will not do this for you. It will execute whichever call you sign, quickly.
