What is Base Chain?
Recently, the Base ecosystem has developed rapidly, and the interactive data on the chain once surpassed the L2 leader Arb and OP ecology, becoming an emerging second-layer network second only to ETH and Binance Chain. During this period, several phenomenal projects have emerged. The Meme coin BALD released on the Base mainnet is a thousand times a day, triggering tens of millions of dollars of hot money to rush to the Base chain, and it only took 2 days for the market value to break through 100 million dollars. The liquidity scale of the pool also exceeded 25 million dollars, which shows its popularity.
The strength of Base comes from its huge background. As the second L2 network deployed on the OP Stack after the Optimism mainnet, it promises the unlimited ambition of CoinBase in the L2 track.
At present, the Base mainnet has been officially opened on August 9th. Users can bridge the ETh in their wallets to the Base network and participate in all Web3 projects on Base at the same time. To celebrate the launch of the Base mainnet, Base officially published a Genesis Builder Commemorative NFT of NFT, as a record of users' early participation in the Base mainnet, and provides you with access to a closed Discord channel with the Base team to ensure you can build seamlessly on Base. In order to qualify, developers need to deploy on the Base mainnet from July 13th to the end of September.
Although the Base official website emphasized on Twitter that there is no airdrop plan for the time being, as a participant of Web3, we still treat each project with the mentality of killing the wrong and not letting go, and the whole task process is not complicated, we still Simple to operate it, so as not to leave regrets when issuing coins in the future, not to mention that we will enter the Base interaction process together.
II. Interactive processes
- Prepare gas and set up Base network
Send 0.01E from ETH mainnet to 0x49048044D57e1C92A77f79988d21Fa8fAF74E97e
This address, this is the official address of Base! You transfer it from the ETH mainnet, and it will automatically return to your Base network wallet, which saves us high cross-chain fees.
- Add Base Network to Wallet
Open the public chain network configuration platform ChainList: Chainlist , enter Base in the text box to find the Base mainnet configuration data, link the wallet disease and add it to the wallet.
The wallet switches to the Base mainnet, and you can see that ETH has been received!
Base mainnet deployment contract
Open the remix online deployment contract website
remix.ethereum.org , directly skip the system prompt that pops up on the website.
- Deploy contract
Click New button
Name the contract file, starting with English, without special characters. Let's take Coinbase as an example here.
Copy and save the following contract code to your newly created contract file, and try to keep the contract name consistent with the name of your newly created file!
Contract Code:
// SPDX-License-Identifier: MIT
pragma solidity >=0.7.0 <0.9.0;
contract Coinbase {
uint public storedData;
function set(uint x) public {
storedData = x;
}
function get() public view returns (uint retVal) {
return storedData;
}
}
