Summary

This smart contract enables decentralized payments with auto-conversion and payment-fee extraction.

The main purpose of this smart contract evolves around the pay function.

This smart contract allows for NATIVE to NATIVE, NATIVE to TOKEN, TOKEN to NATIVE, WRAPPED to NATIVE, NATIVE to WRAPPED and TOKEN_A to TOKEN_B payments.

Transfer polyfil

The DePayRouterV2 emits a InternalTransfer event for payments where the receiver token is the native token of the respective chain (e.g. Ether on Ethereum).

This allows to validate native token transfers without checking for internal transfers, but instead rely on InternalTransfer events, similiar to Token Transfer events.

Standard tokens (e.g. ERC20 etc.) already do emit Transfer events as part of their standard.
