CeresDAO 智能合约是 CeresDAO 生态系统的核心，它为用户提供了稳定币的发行和管理、抵押和借贷、流动性挖矿等功能。

一些简单的合约示例，可以为开发者提供启发，帮助他们更好地了解 CeresDAO 的智能合约功能。

抵押和借贷合约：CeresDAO 智能合约允许用户在抵押一定数量的加密资产后获得借款。用户必须在一定期限内返还借款，并

支付一定的利息。如果用户未能如期偿还，他们的抵押资产将被收回。

以下是一个简单的抵押和借贷合约示例：

contract CollateralLoan {

address public owner;

uint256 public interestRate;

mapping (address => uint256) public loanBalances;

mapping (address => uint256) public collateralBalances;

mapping (address => bool) public approvedCollaterals;

event LoanIssued(address indexed borrower, uint256 amount);

constructor(uint256 _interestRate, address _owner) {

interestRate = _interestRate;
owner = _owner;【更全面的开发源码搭建可看我昵称】

复制代码

}

function borrow(uint256 amount, address collateral) public {

require(amount &gt; 0, &quot;Invalid amount&quot;);
require(collateralBalances[collateral] &gt;= amount, &quot;Insufficient collateral&quot;);
require(approvedCollaterals[collateral] == true, &quot;Collateral is not approved&quot;);
loanBalances[msg.sender] += amount;
collateralBalances[collateral] -= amount;
emit LoanIssued(msg.sender, amount);

复制代码

}

function repay(uint256 amount) public {

require(amount &gt; 0, &quot;Invalid amount&quot;);
require(loanBalances[msg.sender] &gt;= amount, &quot;Insufficient loan balance&quot;);
loanBalances[msg.sender] -= amount;
// TODO: Add interest calculation【更全面的开发源码搭建可看我昵称】

复制代码

}

function approveCollateral(address collateral) public {

require(msg.sender == owner, &quot;Only owner can approve collateral&quot;);
approvedCollaterals[collateral] = true;

复制代码

}

function revokeCollateralApproval(address collateral) public {

require(msg.sender == owner, &quot;Only owner can revoke collateral approval&quot;);
approvedCollaterals[collateral] = false;

复制代码

}

function depositCollateral(uint256 amount, address collateral) public {

require(amount &gt; 0, &quot;Invalid amount&quot;);
collateralBalances[collateral] += amount;

复制代码
