The IFrictionlessTreasuryManager is responsible for all token operations, minting, transferring and burning in the Frictionless protocol. The tokens and their lifecycles are defined in the public README for the Frictionless protocol at https://gitlab.com/dfyclabs/protocol/dfyclabs-tokens/-/tree/main?ref_type=heads#tokens-overview

Functions

setTokensInitData

Sets and associates the implementation authority with the associated token type

function setTokensInitData(FrictionlessTokenInitData[] calldata initDataArr_) external;

Parameters

Name	Type	Description
initDataArr_	FrictionlessTokenInitData[]	the FrictionlessTokenInitData configuration associating the implementation authority with the associated token type.

mintFundDepositForTreasury

Mints a Fund Deposit Token in the specified currency/IBAN pair. This function is invoked to create the genesis mint of the deposit token in the PROTOCOL_TREASURY.

function mintFundDepositForTreasury(
    IFrictionlessFundDepositToken.FFDImmutableData calldata depositData,
    address treasuryAddress,
    uint256 amount
) external returns (address);

Parameters

Name	Type	Description
depositData	IFrictionlessFundDepositToken.FFDImmutableData	the immutable deposit data for the token
treasuryAddress	address	the address of the treasury, which receives the deposit tokens
amount	uint256	the amount of tokens

Returns

Name	Type	Description
<none>	address	address of the token minted emits FrictionlessTokenMinted event throws error FrictionlessTreasuryManagerInvalidDepositData if the deposit data is invalid. requires the depositData.currency to be a 3 letter currency code requires the depositData.description to be not empty requires the depositData.IBAN to be not empty

mintDigitalSecurity

Mints a FrictionlessDigitalSecurityToken as the future dated cash distribution from the underlying FrictionlessOnChainAssetToken. This function is invoked to create the genesis mint of the deposit token in the PROTOCOL_TREASURY.

function mintDigitalSecurity(
    IFrictionlessDigitalSecurityToken.FDSImmutableData memory initData,
    IFrictionlessDigitalSecurityToken.FDSMutableData memory updateData,
    uint256 amount,
    address userAddress
) external returns (address);

Parameters

Returns

mintOnChainAsset

Mints a FrictionlessOnChainAssetToken as the representation of the asset to be securitized, fractionalized & sold. This function is invoked to create the genesis mint of the deposit token to the PERMISSIONED_CUSTODIAN.

function mintOnChainAsset(
    IFrictionlessOnChainAssetToken.FOCASpecData memory specData,
    IFrictionlessOnChainAssetToken.FOCAIssuanceData memory issuanceData,
    IFrictionlessOnChainAssetToken.FOCAUpdateData memory updateData,
    address custodianAddress
) external returns (address);

Parameters

Returns

mintTokenForUser

Used to increase the mint of a Frictionless token which already exists.

function mintTokenForUser(address token, address userAddress, uint256 amount) external;

Parameters

transferToken

Used to increase the mint of a Frictionless token which already exists.

function transferToken(address token, address userAddressFrom, address userAddressTo, uint256 amount) external;

Parameters

burnToken

Used to burn an amount of Frictionless token which already exists.

function burnToken(address token, address userAddress, uint256 amount) external;

Parameters

getFundDepositToken

returns the address of the fund deposit token by currency and fundIBAN

function getFundDepositToken(string calldata currency_, string calldata fundIBAN_) external view returns (address);

Parameters

Returns

getFundDepositTokenKey

returns fund deposit token key by currency and fundIBAN

function getFundDepositTokenKey(string memory currency_, string memory fundIBAN_) external pure returns (bytes32);

Parameters

Returns

Events

FrictionlessTokenMinted

Event emitted when a FrictionlessFundDeposit, FrictionlessDigitalSecurity or FrictionlessOnChainAsset is minted.

event FrictionlessTokenMinted(
    IBasicFrictionlessToken.FrictionlessTokenTypes tokenType,
    address token,
    string tokenName,
    string tokenSymbol,
    uint256 amount,
    address toAddress
);

FrictionlessTokenTransferred

Event emitted when a FrictionlessFundDeposit, FrictionlessDigitalSecurity or FrictionlessOnChainAsset is transferred.

event FrictionlessTokenTransferred(
    IBasicFrictionlessToken.FrictionlessTokenTypes tokenType,
    address token,
    uint256 amount,
    address fromAddress,
    address toAddress
);

FrictionlessTokenBurned

Event emitted when a FrictionlessFundDeposit, FrictionlessDigitalSecurity or FrictionlessOnChainAsset is burned.

event FrictionlessTokenBurned(
    IBasicFrictionlessToken.FrictionlessTokenTypes tokenType, address token, uint256 amount, address fromAddress
);

Errors
