metadata	address	Public
index	uint32	Public
metaIds	mapping(uint32 => uint16)	Private

Modifiers

onlyRole

Restricts the execution of a function to only accounts that have a specific role assigned.

Functions

constructor

Initializes the SABT contract and sets the deployer as the default admin role.

initialize

Initializes the SABT contract with the provided membership and metadata contract addresses.

Parameters

Parameter	Type	Description
membership_	address	The address of the membership contract.
metadata_	address	The address of the metadata contract.

mint

Mints a new SABT token for a specified membership.

Parameters

Parameter	Type	Description
to_	address	The address to mint the token to.
metaId_	uint16	The ID of the token to mint.

Returns the UID (unique identifier) of the minted token.

meta

Retrieves the metadata of a token by its meta ID.

Parameters

Parameter	Type	Description
metaId_	uint16	The meta ID of the token.

Returns the metadata of the token.

metaId

Retrieves the meta ID of a membership token by its UID.

Parameters

Parameter	Type	Description
uid_	uint32	The UID of the membership token.

Returns the meta ID of the membership token.

setMetaId

Sets the meta ID of a membership token.

Parameters

Parameter	Type	Description
uid_	uint32	The UID of the membership token.
metaId_	uint16	The new meta ID for the membership token.

transfer

Transfers a token from the sender to the specified address.

Parameters

Parameter	Type	Description
_to	address	The address to transfer the token to.
_id	uint256	The ID of the token to transfer.

supportsInterface
