ISuperToken

This is the technical reference related to the interface for Super Tokens.

Implementation addresses

Super Token deployments work in a proxy pattern with the original implementation being comon between all super tokens for each chain. The implementation address for the SuperToken is different for each network and can be found in the SuperTokenFactory at the method getSuperTokenLogic.

To get the addresses of all the SuperTokenFactory contracts, you can use the Superfluid Explorer, section Protocol.

ABI

In order to interact with any contract satistying the ISuperToken interface, you can use the following ABI:

Functions

Fn initialize

function initialize(
    contract IERC20 underlyingToken,
    uint8 underlyingDecimals,
    string n,
    string s
) 
    external

Initialize the contract

Parameters

Name	Type	Description
`underlyingToken`	contract IERC20
`underlyingDecimals`	uint8
`n`	string
`s`	string

Fn initializeWithAdmin

function initializeWithAdmin(
    contract IERC20 underlyingToken,
    uint8 underlyingDecimals,
    string n,
    string s,
    address admin
) 
    external

Initialize the contract with an admin

Parameters

Name	Type	Description
`underlyingToken`	contract IERC20
`underlyingDecimals`	uint8
`n`	string
`s`	string
`admin`	address

Fn changeAdmin

function changeAdmin(
    address newAdmin
) 
    external

Only the current admin can call this function if admin is address(0), it is implicitly the host address

Parameters

Name	Type	Description
`newAdmin`	address	New admin address

Changes the admin for the SuperToken

Fn getAdmin

function getAdmin(
) 
    external 
    returns (address admin)

Returns the admin address for the SuperToken

Fn CONSTANT_OUTFLOW_NFT

function CONSTANT_OUTFLOW_NFT(
) 
    external 
    returns (contract IConstantOutflowNFT)

Fn CONSTANT_INFLOW_NFT

function CONSTANT_INFLOW_NFT(
) 
    external 
    returns (contract IConstantInflowNFT)

Fn POOL_ADMIN_NFT

function POOL_ADMIN_NFT(
) 
    external 
    returns (contract IPoolAdminNFT)

Fn POOL_MEMBER_NFT

function POOL_MEMBER_NFT(
) 
    external 
    returns (contract IPoolMemberNFT)

Fn name

function name(
) 
    external 
    returns (string)

Returns the name of the token.

Fn symbol

function symbol(
) 
    external 
    returns (string)

Returns the symbol of the token, usually a shorter version of the name.

Fn decimals

function decimals(
) 
    external 
    returns (uint8)

_Returns the number of decimals used to get its user representation. For example, if decimals equals 2, a balance of 505 tokens should be displayed to a user as 5,05 (505 / 10 ** 2).

Tokens usually opt for a value of 18, imitating the relationship between Ether and Wei. This is the value ERC20 uses, unless setupDecimals is called.

Note

SuperToken always uses 18 decimals.

This information is only used for display purposes: it in no way affects any of the arithmetic of the contract, including IERC20-balanceOf and IERC20-transfer.

Fn totalSupply

function totalSupply(
) 
    external 
    returns (uint256)

See IERC20-totalSupply.

Fn balanceOf

function balanceOf(
    address account
) 
    external 
    returns (uint256 balance)

Returns the amount of tokens owned by an account (owner).

Parameters

Name	Type	Description
`account`	address

Fn transfer

function transfer(
    address recipient,
    uint256 amount
) 
    external 
    returns (bool)

Moves amount tokens from the caller's account to recipient.

Parameters

Name	Type	Description
`recipient`	address
`amount`	uint256

Return Values

Name	Type	Description
`[0]`	bool	Returns Success a boolean value indicating whether the operation succeeded.

Emits

a ERC20 Transfer event.

Fn allowance

function allowance(
    address owner,
    address spender
) 
    external 
    returns (uint256)

Returns the remaining number of tokens that spender will be allowed to spend on behalf of owner through transferFrom. This is zero by default.

Parameters

Name	Type	Description
`owner`	address
`spender`	address

This value changes when approve or transferFrom are called.

Fn approve

function approve(
    address spender,
    uint256 amount
) 
    external 
    returns (bool)

Sets amount as the allowance of spender over the caller's tokens.

Parameters

Name	Type	Description
`spender`	address
`amount`	uint256

Return Values

Name	Type	Description
`[0]`	bool	Returns Success a boolean value indicating whether the operation succeeded.

Note

Beware that changing an allowance with this method brings the risk that someone may use both the old and the new allowance by unfortunate transaction ordering. One possible solution to mitigate this race condition is to first reduce the spender's allowance to 0 and set the desired value afterwards: https://github.com/ethereum/EIPs/issues/20#issuecomment-263524729

Emits

an Approval event.

Fn transferFrom

function transferFrom(
    address sender,
    address recipient,

    returns (bool)

Moves amount tokens from sender to recipient using the allowance mechanism. amount is then deducted from the caller's allowance.

Parameters

Name	Type	Description
`sender`	address
`recipient`	address

Return Values

Name	Type	Description
`[0]`	bool	Returns Success a boolean value indicating whether the operation succeeded.

`addedValue`	uint256

Emits

an Approval event indicating the updated allowance.

@custom:requirements
