Why does Request ask for slightly more than my payment total?
Why does Request ask for slightly more than my payment total?

There are two reasons for this, which are as follows:

  1. When you are paying for an invoice denominated in fiat, prices are calculated on-chain via ChainLink, we ask for a little extra during each payment to account for any exchange rate discrepancies by the time your transaction gets confirmed. e.g. imagine paying a EUR denominated with DAI, and the transaction takes a few minutes to confirm; when we check with ChainLink, the EUR/DAI price may have dropped slightly. Because of this, we require a small % extra to cover the full amount. After the transaction has been completed, any excess is sent back directly to the payer.

  1. When you are paying via our swap mechanism, the swaps can occur slippage from the exchange (e.g., DAI/USDT swap may cause 0.1% slippage + also fees), so again, we ask for extra. After the transaction has been completed, any excess is sent back directly to the payer.
