 RMRK is a set of NFT standards that compose several NFT module primitives. Putting these modules together allows a user to create NFT systems of arbitrary complexity.
 So far we have created 6 modules as ERC proposals, all of which are ERC721 compatible. The first 5 are already standards, the 6th is still in Draft.

+## Methods
+
+### balanceOfERC20
+
+```solidity
+function balanceOfERC20(address erc20Contract, uint256 tokenId) external view returns (uint256)
+```
+
+Used to retrieve the given token's specific ERC-20 balance
+
+
+
+#### Parameters
+
+| Name | Type | Description |
+|---|---|---|
+| erc20Contract | address | The address of the ERC-20 smart contract |
+| tokenId | uint256 | The ID of the token being checked for ERC-20 balance |
+
+#### Returns
+
+| Name | Type | Description |
+|---|---|---|
+| _0 | uint256 | The amount of the specified ERC-20 tokens owned by a given token |
+
+### erc20TransferOutNonce
+
+```solidity
+function erc20TransferOutNonce(uint256 tokenId) external view returns (uint256)
+```
+
+Nonce increased every time an ERC20 token is transferred out of a token
+
+
+
+#### Parameters
+
+| Name | Type | Description |
+|---|---|---|
+| tokenId | uint256 | The ID of the token to check the nonce for |
+
+#### Returns
+
+| Name | Type | Description |
+|---|---|---|
+| _0 | uint256 | The nonce of the token |
+
+### supportsInterface
+
+```solidity
+function supportsInterface(bytes4 interfaceId) external view returns (bool)
+```
+
+
+
+*Returns true if this contract implements the interface defined by `interfaceId`. See the corresponding https://eips.ethereum.org/EIPS/eip-165#how-interfaces-are-identified[EIP section] to learn more about how these ids are created. This function call must use less than 30 000 gas.*
+
+#### Parameters
+
+| Name | Type | Description |
+|---|---|---|
+| interfaceId | bytes4 | undefined |
+
+#### Returns
+
+| Name | Type | Description |
+|---|---|---|
+| _0 | bool | undefined |
+
+### transferERC20ToToken
+
+```solidity
+function transferERC20ToToken(address erc20Contract, uint256 tokenId, uint256 amount, bytes data) external nonpayable
+```
+
+Transfer ERC-20 tokens to a specific token.
+
+*The ERC-20 smart contract must have approval for this contract to transfer the ERC-20 tokens.The balance MUST be transferred from the `msg.sender`.*
+
+#### Parameters
+
+| Name | Type | Description |
+|---|---|---|
+| erc20Contract | address | The address of the ERC-20 smart contract |
+| tokenId | uint256 | The ID of the token to transfer ERC-20 tokens to |
+| amount | uint256 | The number of ERC-20 tokens to transfer |
+| data | bytes | Additional data with no specified format, to allow for custom logic |
+
+### transferHeldERC20FromToken
+
+```solidity
+function transferHeldERC20FromToken(address erc20Contract, uint256 tokenId, address to, uint256 amount, bytes data) external nonpayable
+```
+
+Transfer ERC-20 tokens from a specific token.
+
+*The balance MUST be transferred from this smart contract.Implementers should validate that the `msg.sender` is either the token owner or approved to manage it before calling this.Must increase the transfer-out-nonce for the tokenId*
+
+#### Parameters
+
+| Name | Type | Description |
+|---|---|---|
+| erc20Contract | address | The address of the ERC-20 smart contract |
+| tokenId | uint256 | The ID of the token to transfer the ERC-20 tokens from |
+| to | address | undefined |
+| amount | uint256 | The number of ERC-20 tokens to transfer |
+| data | bytes | Additional data with no specified format, to allow for custom logic |
+
