//no parameter
const signer = library.getSigner();
let contract = new ethers.Contract(stakingContractAddress, stakeAbi, signer);
const estimation = await contract.estimateGas.getReward();
let tx = await contract.getReward({
gasLimit: estimation,
});
const receipt = await tx.wait();

// with parameter (2 parameter amount and value )
setIsMintLoading(true);
// const provider = new ethers.providers.Web3Provider(_provider.browserWeb3Provider);
const signer = library.getSigner();
let contract = new ethers.Contract(SmartContractConfig.address[25], SmartContractConfig.abi, signer);
let totalCost = currentPrice * amount;
let totalCostWei = totalCost * 10 ** 18;
const estimation = await contract.estimateGas.mintSaint(amount.toString(), { value: totalCostWei.toString() });
let tx = await contract.mintSaint(amount.toString(), {
gasLimit: estimation,
