Simple Summary

An ERC20 abstraction to aggregate multiple ERC20 tokens, also recursively.

Abstract

This standard allows software to inspect multitokens nested tokens and allows to mint/burn them.

Token

ERC20 Methods

All usual ERC20 methods.

ERC1133 Methods

tokensCount - ERC1133

function tokensCount() public view returns (uint256);

The number of tokens inside this multi-token.

tokens - ERC1133

function tokens(uint256 index) public view returns (ERC20);

The subtoken by index from 0 to tokensCount()-1.

allTokens - ERC1133

function allTokens() public view returns (ERC20[]);

All subtokens in array

allBalances - ERC1133

function allBalances() public view returns (uint256[]);

All subtokens balances in array

mintFirstTokens - ERC1133

Implementation example:

function mintFirstTokens(address _to, uint256 _amount, uint256[] _tokenAmounts) public {
    require(totalSupply_ == 0, "This method can be used with zero total supply only");
    ...
}

mint - ERC1133

Implementation example:

function mint(address _to, uint256 _amount) public {
    require(totalSupply_ != 0, "This method can be used with non zero total supply only");
    ...
}

burn - ERC1133

Implementation example:

function burn(uint256 _value) public {
    burnSome(_value, tokens);
}

burnSome - ERC1133

Implementation example:

function burnSome(uint256 _value, ERC20[] someTokens) public {
    ...
}

Should allow you to redeem your share of any token (not only nested to this multi-token), including updated or AirDropped.

Is it not another nested token ERC? I just can't remember which it was

@k06a are you still pursuing this since #1155 is final or can we close this?

[k06a]

@axic this is a completely different standard, but with a similar name. I will rename it and update.
