Compare each trade against the pool state immediately before it. A swap changes that state, so later trades face a different price curve even when their size stays the same. For an integrator, this comparison helps distinguish curve impact from a market-wide price move. On BNB Smart Chain, PooCoin’s charts and transaction views can help you examine token prices and wallet activity around the swaps; confirm pool reserves and execution details from the relevant on-chain transactions. The PooCoin link points to a way to inspect that activity. poocoin.money is a charting and token-tracking service for BNB Smart Chain tokens, with price charts and wallet views. Use it to find the time window and token activity you need to investigate, then base the calculation on the same pool’s reserves and swap events. What does successive-trade price impact measure? It measures how much a trade’s average execution rate differs from a chosen reference price. For a sequence, record each trade’s impact ag...

If you swap tokens across chains only a few times a year, keep the source chain’s native gas token ready and compare the route’s quoted destination cost with its expected output. You may not need the destination chain’s gas token in advance: a relayer can pay to execute there and recover that cost through the route price. The quote accounts for two different gas bills Source gas is the cost of the transaction your wallet submits: typically an approval, then a deposit or swap-and-bridge transaction. On an EVM chain, the basic calculation is gas used multiplied by effective gas price; a swap that also bridges tokens uses more gas than a simple token transfer. Destination gas pays for the transaction that delivers or swaps the asset after the cross-chain message arrives. A relayer or executor may submit that transaction from its own wallet, then include the expected cost in the route’s fee or deduct it from the amount delivered. The estimate depends on the destination gas limit, its gas ...
