Solidity

Solidity is a programming language developed by Gavin Wood, Christian Reitwiessner, Alex Beregszaszi and other Ethereum Contributors. Solidity programming language is influenced by C++, Javascript and Python programming languages.

Metamask

To detect metamask on user browser use this syntax :

if (window.ethereum) {
  //form.classList.add("has-eth"); //display web3 apps, widget, etc
}

If we want to initiate request to metamask use this scripts :

window.ethereum.request({
    method: "eth_requestAccounts",
});

Here is the example to send native token using metamask :

const send = async function send(amount) {
  const accounts = await window.ethereum.request({
    method: "eth_requestAccounts",
  });

  const wei = web3.utils.toWei(amount, "ether");

  if (accounts.length > 0) {
    window.ethereum.request({
      method: "eth_sendTransaction",
      params: [
        {
          from: accounts[0],
          to: "0x7ceb23fd6bc0add59e62ac25578270cff1b9f619",
          value: web3.utils.toHex(wei),
        },
      ],
    });
  }
};
