Write Functions
Function
Description
transferTokenForced()

approve()
Approve the _spender address_ to spend the specified amount of tokens on behalf of the function caller’s address
bulkTransfer()
Perform multiple token transfers from the token owner's address. The tokens must already be minted. Can only be executed by a delegate 1. Token issuer must first specify a delegate (owner is not a delegate by default) to use this function 2. Token issuer must call approve() function to allow delegate to spend
burnAccount()
Burns an amount of tokens from a specified address. Tokens are sent to the zero address, Only token issuers can call this function
transferFrom [from, to, value]
Internal function used by the Transfer Rules contract of this SRC20 to check if a transfer requires an authorization
transferToken()
Transfer token to specified address. Caller needs to provide an authorization signature obtained from MAP API, signed by an authority accepted by the token issuer. Used by the _transfer_ function after _transfer validity_ is acquired
increaseAllowance()

If this function is called by someone other than the owner (must be a delegate defined in the Roles contract of this SRC20, the owner has to call approve() first to set up the delegate's allowance. Data needs to be packed correctly before calling this function
burn()
