Crypto store cut to one wallet address and unique payment amounts across six chains
A small digital goods seller initially accepted only BEP20 USDT on BSC, and despite a working payment setup, made zero sales over two weeks. Buyers who had funds on other chains left at the payment screen because they could not pay with the assets they held. The seller rebuilt the checkout around a single wallet address that accepts two stablecoins across six chains. Orders are identified by unique micro-amounts rather than per-chain order numbers, with a watcher scanning all enabled chains for matching transfers. The article also covers pitfalls such as differing token decimals between chains and the need for server-side log filtering to keep RPC usage manageable.
