All of these features made it into this version of the plugin, except for smart contract wallet support - issues processing transactions stemming from sc wallets meant that we ultimately had to turn away sc wallet payments altogether. -## Event Setup Instructions -1.

If EUR was chosen, then this says 1 ETH = 4000EUR. - - Select the networks you want under the "Networks" option - Choose from Ethereum Mainnet, Optimism, Arbitrum and their testnets. - - "NETWORK_RPC_URLS" - This is a JSON e.g. - ``` - { - "L1_RPC_URL": "https://mainnet.infura.io/v3/somekeyhere", - "Rinkeby_RPC_URL": "...", - "RinkebyArbitrum_RPC_URL": "..." - } - ``` - i.e. `KEY` = `_RPC_URL` and `VALUE` = RPC URL.
