TokenAllowListEnabled

Emitted when the restriction of collateralToken and paymentToken to allow-listed tokens is toggled on or off.

Errors

CollateralTokenAmountLessThanConvertibleTokenAmount

• There must be more collateralTokens than convertibleTokens.

InvalidDeposit

• Fails if the collateralToken takes a fee.

InvalidMaturity

• Maturity date is not valid.

TokensMustBeDifferent

• The paymentToken and collateralToken must be different.

TooManyDecimals

• Decimals with more than 18 digits are not supported.

ZeroBondsToMint

• Bonds must be minted during initialization.

Methods

ALLOWED_TOKEN

function ALLOWED_TOKEN() external view returns (bytes32)

The role given to allowed tokens.

Returns

DEFAULT_ADMIN_ROLE

function DEFAULT_ADMIN_ROLE() external view returns (bytes32)

Returns

ISSUER_ROLE

function ISSUER_ROLE() external view returns (bytes32)

The role required to issue bonds.

Returns

createBond

function createBond(string name, string symbol, uint256 maturity, address paymentToken, address collateralToken, uint256 collateralTokenAmount, uint256 convertibleTokenAmount, uint256 bonds) external nonpayable returns (address clone)

Creates a new Bond. The calculated ratios are rounded down.

Parameters

string	name	Passed into the ERC20 token to define the name.
string	symbol	Passed into the ERC20 token to define the symbol.
uint256	maturity	The timestamp at which the Bond will mature.
address	paymentToken	The ERC20 token address the Bond is redeemable for.
address	collateralToken	The ERC20 token address the Bond is backed by.
uint256	collateralTokenAmount	The amount of collateral tokens per bond.
uint256	convertibleTokenAmount	The amount of convertible tokens per bond.
uint256	bonds	The amount of Bonds given to the owner during the one-time mint during the `Bond`'s `initialize`.

Returns

getRoleAdmin

function getRoleAdmin(bytes32 role) external view returns (bytes32)

Returns

isBond

function isBond(address) external view returns (bool)

Returns whether or not the given address key is a bond created by this Bond factory.

Parameters

Returns

isTokenAllowListEnabled

function isTokenAllowListEnabled() external view returns (bool)

function setIsIssuerAllowListEnabled(bool _isIssuerAllowListEnabled) external nonpayable

Sets the state of bond restriction to allow-listed accounts.

Parameters

setIsTokenAllowListEnabled

function setIsTokenAllowListEnabled(bool _isTokenAllowListEnabled) external nonpayable

Sets the state of token restriction to the list of allowed tokens.

Parameters

supportsInterface

function supportsInterface(bytes4 interfaceId) external view returns (bool)

Parameters

Returns

tokenImplementation

function tokenImplementation() external view returns (address)

Address where the bond implementation contract is stored.
