     srcChainId,
     nftCollectionAddress,
     tokenId,
     provider,
     account,
   });

Example

ReactJs Example using web3-react

import { approve, bridge } from 'parakeet-bridge-sdk/src/';
import { useWeb3React } from '@web3-react/core';

const useBridge = () => {
  const { account, library } = useWeb3React();

  //  rinkeby
  const srcChainId = 4;

  // optimism kovan
  const dstChainId = 69;

  // address of the NFT collection on the source chain -> on Rinekby(in this example)
  const nftCollectionAddress = '...';

  // token Id owned by account
  const tokenId = '...';

  //  provider
  let provider;
  // in case of ethers.js
  provider = library.provider;
  // in case of web3.js
  provider = library.currentProvider;
  
  const estimateFee = async () => {
   
    try {
      const estimatedFees = await estimateBridgeFees({
        account,
        dstChainId,
        srcChainId,
        provider,
        tokenId,
        nftSrcContractAddress
      });
      console.log(estimateFee)
    } catch (err) {
      console.error(err);
    }
};

  const bridgeNFT = async () => {
    try {
      const approveTx = await approve(
        srcChainId,
        nftCollectionAddress,
        tokenId,
        provider,
        account
      );

      const bridgeTx = await bridge(
        srcChainId,
        dstChainId,
        nftCollectionAddress,
        tokenId,
        provider,
        account
      );
    } catch (err) {
      console.log(err);
    }
    return { approveTx, bridgeTx };
  };

  return { bridgeNFT };
};
