Understanding the "Base Contract Not Supported" Error
To effectively tackle the "Base contract is not supported" error, it's crucial to first understand its root causes. This error message indicates that the Safe Core SDK is unable to locate or interact with the base contract necessary for deploying a Safe wallet. This can occur due to several reasons, including incorrect contract addresses, network mismatches, or issues with the SDK's configuration. Specifically, when deploying a Safe from Safe Core SDK, the SDK needs to reference a base contract that serves as a template for the new Safe wallet. If the SDK cannot find or properly interface with this base contract, the deployment process will fail, resulting in the aforementioned error.
One of the primary reasons for this error is an incorrect contract address. The Safe Core SDK relies on specific contract addresses for various functionalities, including the deployment of new Safes. If the address for the base contract is misconfigured or outdated, the SDK will be unable to locate the necessary contract, leading to the error. Another common cause is a mismatch between the network configured in the SDK and the network on which the base contract is deployed. For instance, if the SDK is set to deploy on a test network, but the base contract exists only on the main network, the deployment will fail. Additionally, issues within the SDK's configuration, such as incorrect provider settings or outdated dependencies, can also contribute to this error. A deep understanding of these potential causes is the first step in effectively troubleshooting and resolving the "Base contract not supported" error.
Common Causes of the Error
There are several factors that can lead to the "Base contract is not supported" error when deploying a Safe wallet using the Safe Core SDK v1.4.1. Identifying these common causes is essential for efficient troubleshooting and resolution. Let's explore some of the most frequent reasons:

One of the primary culprits behind this error is the use of incorrect contract addresses. The Safe Core SDK requires precise addresses for the base contracts it interacts with during deployment. If these addresses are misconfigured, outdated, or simply incorrect, the SDK will be unable to locate the necessary contract, resulting in the error. This is particularly important to verify when working with different networks (e.g., mainnet, testnets) as contract addresses can vary significantly between them. Ensure that the contract addresses specified in your SDK configuration align with the network you are deploying to.
2. Network Mismatches
Another common cause is a network mismatch between the SDK's configuration and the actual network where the base contract is deployed. For instance, if your SDK is configured to interact with a test network (like Goerli or Sepolia), but the base contract is deployed only on the mainnet, the deployment will fail. It's crucial to confirm that the network settings in your SDK match the intended deployment environment. This involves checking the network ID, chain ID, and the provider URL used by the SDK.
3. SDK Configuration Issues
SDK configuration issues can also contribute to the "Base contract not supported" error. This includes problems such as incorrect provider settings, outdated dependencies, or misconfigured initialization parameters. The SDK relies on a properly configured provider to interact with the blockchain, and if the provider is not set up correctly, it can lead to connectivity issues and the inability to locate the base contract. Similarly, outdated dependencies within the SDK can cause compatibility problems, especially if the base contracts have been updated. Ensure that your SDK is configured with the correct provider, and all dependencies are up-to-date.
4. Contract Deployment Issues
In some cases, the error might stem from issues with the deployment of the base contract itself. Although less frequent, it's possible that the base contract was not deployed correctly on the target network, or there were problems during the deployment process. This could result in the contract not being accessible or functioning as expected. While this is less likely if you are using a well-established network and contract, it's still worth considering as a potential cause. You can verify the contract's deployment status by checking the blockchain explorer for the relevant network.
5. Incompatible SDK Version
Lastly, using an incompatible SDK version can also trigger this error. If the version of the Safe Core SDK you are using is not compatible with the base contracts deployed on the network, it can lead to deployment failures. This is particularly relevant when there are significant updates or changes to the Safe contract architecture. Always ensure that your SDK version is compatible with the base contracts you intend to use. Refer to the Safe Core SDK documentation for compatibility information and recommended versions.
