English version

Upgradeable contracts are contracts whose logic can be modified after deployment. This is typically achieved using the proxy pattern. Upgradeability provides flexibility but adds complexity and centralization risks. OpenZeppelin's upgradeable contracts library is widely used.

Code Example

// Contrat upgradeable avec OpenZeppelin
import "@openzeppelin/contracts-upgradeable/proxy/utils/Initializable.sol";

contract MyContractV1 is Initializable {
    uint256 public value;

    function initialize(uint256 _value) public initializer {
        value = _value;
    }
}

// V2 ajoute des fonctionnalités
contract MyContractV2 is Initializable {
    uint256 public value;
    uint256 public newFeature;

    function setNewFeature(uint256 _value) public {
        newFeature = _value;
    }
}
