To use DLCs from your Ethereum contract, and let users move native bitcoin directly, import our contract and call the public functions as shown below.
Note: to always get the most up to date information about the library, please see the README of the repo here: https://github.com/DLC-link/dlc-solidity
// In your constructor, create your DLCManager instance, pointing to our public contract.
DLCManager _dlcManager = DLCManager(publcDLCManagerContractAddress);
// createDLC: Creates the DLC in the DLC Manager contract, as well as in the Oracle network.
// emergencyRefundTime: The time at which the DLC can be cancelled, if any. Format: seconds from epoch
// nonce: An ID unique to this application to match the response in the callback.
bytes32 dlcUUID = _dlcManager.createDLC(emergencyRefundTime, nonce);
// Overwrite this function to complete your DLC setup logic
function postCreateDLCHandler(bytes32 uuid) external;
// Overwrite this function to run custom logic when the DLC has been funded
function setStatusFunded(bytes32 uuid) external;
// If desired, mint an NFT representing the Bitcoin contract which can be transfered and borrowed against.
// Overwrite this function to complete the mintNFT logic
function postMintBtcNft(bytes32 uuid, uint256 nftId) external;
// Overwrite this function to receive the price of BTC when closing the DLC
function getBtcPriceCallback(bytes32 uuid, int256 price, uint256 timestamp) external;
// Close the DLC, which sends the collateral out of the Bitcoin DLC at the given ratio.
// payoutRatio: Number between 0 and 100 representing the % of bitcoin paid out from the DLC to the original participants
// 0 means the user gets all the collateral, 100 means this contract gets all the collateral.
// Overwrite this function to complete the close DLC logic
function postCloseDLCHandler(bytes32 uuid) external;
