README

@iota/iscmagic

The Magic contract is an EVM contract deployed by default on every ISC chain, in the EVM genesis block, at address 0x1074000000000000000000000000000000000000. The implementation of the Magic contract is baked-in in the evm core contract; i.e. it is not a pure-Solidity contract.

The Magic contract has several methods, which are categorized into specialized interfaces: ISCSandbox, ISCAccounts, ISCUtil and so on. You can access these interfaces from any Solidity contract by importing this library.

The Magic contract also provides proxy ERC20 contracts to manipulate ISC base tokens and native tokens on L2.

Read more in the Wiki.

Installing @iota/iscmagic contracts

The @iota/iscmagic contracts are installable via NPM with

npm install @iota/iscmagic

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

pragma solidity >=0.8.5;

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

contract MyEVMContract {
    event EntropyEvent(bytes32 entropy);

    // this will emit a "random" value taken from the ISC entropy value
    function emitEntropy() public {
        bytes32 e = ISC.sandbox.getEntropy();
        emit EntropyEvent(e);
    }
}

Functions

func ERC20ExternalNativeTokensAddress added in v1.0.3 

func ERC20ExternalNativeTokensAddress(
	nativeTokenID iotago.NativeTokenID,
	isTaken func(common.Address) bool,
) (common.Address, error)

ERC20ExternalNativeTokensAddress creates an Ethereum address for an ERC20 contract for native tokens with an off-chain foundry. NOTE: since len(NativeTokenID) == 38 and len(Address) == 20, it is not possible to assign a unique address to every native token. This function tries to form the ERC20 address from the first 17 bytes of hash(nativeTokenID). In case of a collision, it reapplies the hash and checks for a collision again, repeating until it gives up.

func ERC20NativeTokensAddress added in v1.0.3 

func ERC20NativeTokensAddress(foundrySN uint32) common.Address

ERC20NativeTokensAddress returns the Ethereum address of the ERC20 contract for native tokens with an on-chain foundry.
