 Where `$SEI_NODE_URI` is the URI of the Sei node and `$MNEMONIC` is the mnemonic of the account that will deploy the contract. If you run local Sei node, the address will be `http://localhost:8545` , otherwise you could grab a `evm_rpc` url from the [registry](https://github.com/sei-protocol/chain-registry/blob/main/chains.json). If deployment is successful, you will get the EVM contract address in the output.
