Buidl, Quickly
We're excited to announce that we're developing a comprehensive template for developers to leverage the popular starter kit Scaffold-ETH (opens in a new tab).
You will notice the contract example #2 within the Remix section is part of this repository.
- BidBoard.sol
// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.13;
contract BidBoard {
string public message;
address public currentAdvertiser;
uint public currentAmount;
address payable public owner;
event MessageUpdated(
string newMessage,
address indexed newAdvertiser,
uint newAmount
);
constructor() {
owner = payable(msg.sender);
message = "Welcome to Apechain";
}
modifier onlyOwner() {
require(msg.sender == owner, "Only the owner can call this function.");
_;
}
function updateMessage(string calldata newMessage) external payable {
require(
msg.value > currentAmount,
"Must send more Ether than the previous amount."
);
message = newMessage;
currentAdvertiser = msg.sender;
currentAmount = msg.value;
owner.transfer(msg.value);
emit MessageUpdated(newMessage, msg.sender, msg.value);
}
function updateOwner(address payable newOwner) external onlyOwner {
owner = newOwner;
}
}
Also, adjustments have been made to the hardhat.config.ts file
apeCurtis: {
url: `https://curtis.rpc.caldera.xyz/http/${providerApiKey}`,
accounts: [deployerPrivateKey],
},
Here is a Link to the current version (opens in a new tab) of the buildkit, we welcome all contributions towards this effort to ensure developers can start building as quickly as possible.
yarn install yarn deploy yarn start As a user, you'll notice locally you can connect immediately to the Curtis network which will display your holdings with your connected wallet and the block explorer auto-directs you to the Curtis block explorer. You can update the message and set a value behind the message.
As a user, you are bidding to update the message (string) so, to update the message you need to ensure you are paying more than the previous update, otherwise, it will fail to update the state.
