Each contributor address holds an array of a Contribution structure like this struct Contribution {address currency;uint256 amount;uint256 sequence;ContributionStatus status;}
bufferedContributions[address][address] returns (uint256)

Function
Description
setupContract(uint256, uint256, address, address, bool)
This function finishes setting up the contract once it has been deployed. The parameters are the following: 1/ Minimum contribution amount accepted in base currency; 2/ Maximum contribution amount accepted in base currency; 3/ Affiliate Manager contract address; 4/ Contributor Restrictions contract address; 5/ A boolean that sets if the contributions are locked
cancelFundraise() returns (bool)
It cancels the fundraise; this function can only be called by the contract owner (token issuer)
getContributionsBCY(address, bool) returns (uint256)
Returns the contributor’s sum of contributions in base currency; the contributor’s address is the first parameter and the second parameter is a boolean for qualified contributions (true) or pending contributions (false)
addOffchainContribution(address, address, uint256) returns (bool)
If off-chain contributions are allowed the token issuer can add contributions manually so the contract can later mint and distribute tokens for manual contributions; this feature requires trust on the part of the token issuer
contribute(address, uint256, string) returns (bool)
Allow contributions of ERC20 tokens that are registered in the Currency Registry contract. The first parameter is the address of the ERC20, the second is the amount in Wei and the third is the affiliate link if there is one; e.g. to contribute 100 DAI with affiliate link name affiliate use contribute("0x6b175474e89094c44da98b954eedeac495271d0f",100000000000000000000,"affiliate")
getRefund() returns (bool)
Allow a user to get ERC20 and ETH refunds if the fundraise has passed expiration time or has been cancelled
acceptContributor(address) returns (bool)
Function that can only be called by the Contributor Restriction smart contract after a user has been whitelisted by the issuer
removeContributor(address) returns (bool)
Function that can only be called by the Contributor Restriction smart contract after a user's address has been unwhitelisted by the token issuer
stakeAndMint(address, uint256) returns (bool)
Allow token issuer to stake SWM tokens in order to mint SRC20 tokens. The token issuer can either use ISOP or stake directly if they have the required SWM. The stakeAndMint() function will also conclude the fundraise by internally calling the function finishFundraise(). When stakeAndMint() finalizes the fundraise, that the people whitelisted for a fundraise are automatically added to the SRC20 Transfer Rules via bulkWhitelistAccount(). Otherwise stakeAndMint() could run into problems because the holders are not able to hold the newly minted SRC20 tokens
claimTokens() returns (uint256)
Allow contributors to claim their portion of SRC20 tokens after the fundraising is successfully over
