Collections — Supply

Dashboard​

When creating collection via Dashboard, or React hooks you will be able to specify max supply when deploying your contract.

React Hooks​

useTotalSupply​

Current total number of minted tokens in this collection.

import { useTotalSupply } from "flair-sdk";

const App = () => {
  const { data, error, isLoading } = useTotalSupply({
    contractAddress: "0x123412341234123412341234123412341234",
    enabled: true, // (optional) whether to fetch on initial render
  });

  return <div>Current total supply: {data}</div>;
};

useMaxSupply​

Maximum number of tokens that can ever be minted on the collection.

import { useMaxSupply } from "flair-sdk";

const App = () => {
  const { data, error, isLoading } = useMaxSupply({
    contractAddress: "0x123412341234123412341234123412341234",
    enabled: true, // (optional) whether to fetch on initial render
  });

  return <div>Max supply: {data}</div>;
};

Solidity Extensions​

This extensions sets a maximum supply for your ERC721 collection, and tracks mints using an auto-incremented ID starting from 1.
