swapFromEvm returns an order hash instead of a transaction hash. Pass that to the same endpoint.
How often to poll
Poll every 2 seconds. Most swaps settle in seconds, so a slower interval makes your interface look laggy when the swap is already done. Without an API key you are rate limited per IP, which is fine for development and for moderate production volume. If you are polling at scale, request a key from support@mayan.finance and pass it asapiKey.
