EVM support

This package and subpackages contain the code for the evm core contract, which allows to execute Ethereum VM (EVM) code on top of the ISC chain, thus adding support for Ethereum smart contracts.

Installing @iscmagic contracts

The @iscmagic contracts are installable via NPM with

npm install --save @iota/iscmagic

After installing @iota/iscmagic you can use the functions by importing them as you normally would.

import "@iota/iscmagic/ISC.sol"
...
...

JSON-RPC

The Wasp node provides a JSON-RPC service at /chain/<isc-chainid>/evm/jsonrpc. This will allow you to connect any standard Ethereum tool, like Metamask. You can check the Metamask connection parameters for any given ISC chain in the Dashboard.

Complete example using wasp-cluster

1. Start a test cluster:

   wasp-cluster start -d
   

2. In a different terminal, initialize a private key and request some iotas from the faucet:

   wasp-cli init
   wasp-cli request-funds
   

3. Deploy an ISC chain with an arbitrary Ethereum chain ID (which should be different from any standard Ethereum chain IDs -- see https://chainlist.org):

   wasp-cli chain deploy --chain=mychain --evm-chainid 1234
   

4. Send some base tokens from your L1 account to any Ethereum account on L2 (e.g. to cover for gas fees):

   wasp-cli chain deposit 0xa1b2c3d4... base:1000000
   

5. Visit the Wasp dashboard (<URL>/wasp/dashboard when using node-docker-setup), go to Chains, then to your ISC chain, scroll down and you will find the EVM section with the JSON-RPC URL for Metamask or any other Ethereum tool.

You can now deploy an EVM contract like you would on Ethereum.
