How to use the arc.getArcSettings function in arc

const signature1 =  signature.substring(0, signature.length-2);
      const v = signature.substring(signature.length-2, signature.length);
      if (v === "00") {
        signature = signature1+"1b";
      } else {
        signature = signature1+"1c";
      }
      const signatureType = 1;
      // const scheme = arc.scheme(schemeState.id);
      // const reputationFromTokenScheme = scheme.ReputationFromToken as ReputationFromTokenScheme;
      const contract =  arc.getContract(schemeState.address);

      // send the transaction and get notifications
      if (contract) {
        // more information on this service is here: https://github.com/dOrgTech/TxPayerService
        const txServiceUrl = getArcSettings().txSenderServiceUrl;
        const data = {
          to: schemeState.address,
