Contract: Pool-Based Transfer Refund
Trigger cBridge `withdraw` function with all needed info. Then cBridge contract will transfer corresponding assets back to user's address on source chain
Certain failed transfers sent via the pool-based Bridge can be refunded using the withdraw function. Please read the gateway refund process first to learn how to obtain the parameters required. NOTE: DO NOT call addLiquidity from a smart contract, as currently it is not possible to withdraw liquidity added from contract addresses.
Here is the abi for Bridge: https://github.com/celer-network/cBridge-typescript-client/tree/main/contract/abi/Bridge.sol
bridge.withdraw(wdmsg, sigs, signers, powers)
wdmsg | BytesLike | wd_onchain |
sigs | Array<BytesLike> | sorted_sigs |
signers | Array<String> | signers |
powers | Array<BigNumber> | powers |
Notice: Since the types of parameters are different between getTransferStatus response and withdraw request, please convert them accordingly. See details in the below code sample
JavaScript
import { base64, getAddress, hexlify } from "ethers/lib/utils";
const wdmsg = base64.decode(wd_onchain);
const signers = _signers.map(item => {
const decodeSigners = base64.decode(item);
const hexlifyObj = hexlify(decodeSigners);
return getAddress(hexlifyObj);
});
const sigs = sorted_sigs.map(item => {
return base64.decode(item);
});
const powers = _powers.map(item => {
return base64.decode(item);
});
Since this function is an Ethereum on-chain transaction, the response is the corresponding transaction response.
