The funding rate accounting occurs block-by-block, and the payment is made during updates, close, and once every 24 hours. Every position has the maximum possible funding rate payout locked in the liquidation margin, ensuring the accounting will settle correctly. You can view the current total funding fee payment up to the present block in the open positions table, specifically in the "Fees" column under the "+" button.
The actual payments produce on-chain events labeled "funding-payment," which includes the amount. However, the associated funds transfer message might be missing because the market contract holds the funds for all positions. To view these events on mintscan, find your update or close transaction, open the "Event Logs" tab, and look for "Wasm Funding Payment" events. Identifying the "cranks" associated with a particular position might be challenging without a program, but the event displays the position id for filtering.
