Deploying Solana Contracts on Localnet: A Troubleshooting Guide
Solana is a popular, fast, and scalable blockchain platform that allows developers to build decentralized applications (dApps) and participate in the Solana network. However, one of the most common issues when deploying Solana contracts on localnet is errors during the deployment process. In this article, we will examine the causes of this issue and provide a step-by-step guide to resolving it.
The error message
When you try to deploy (pin) a Solana contract on your local network, you get the following error message:
Installing cluster:
Update permission: /Users/bla/.config/solana/id.json
Installing program...
This error indicates that the Solana client is trying to connect to a local network node at ” which is the default local network port used by Solana clients. However, you are trying to update an anchor contract using a different endpoint.
Causes of the problem
There are several reasons why your Solana client may have problems deploying contracts on a local network:
- Incorrect Update Permission: The “Update Permission” field in the .id.json file should point to a local network node, not a regular Solana node.
- Incorrect Cluster: Make sure the cluster you are trying to deploy to is indeed a local network and not another network (e.g. Mainnet).
- Localnet Node Not Started: Make sure the local network node is up and running before attempting to deploy contracts.
Solutions
To resolve this issue, follow these steps:
- Check the
.id.json' file: Verify that the "Update Permission" field points to a local network node, for example:
{
"name": "localnet-01",
"path": "/Users/bla/.config/solana/id.json"
}
- Check the Localnet node
: Verify that the local network node is up and running by checking the logs or using a command line tool such as "solana-cli":
solana-cli --port=8899 --node=/path/localnetworknode
- Use the correct cluster: Verify that the cluster you are trying to deploy to is a local network and not another network:
{
"name": "localnet",
"path": "/Users/bla/.config/solana/id.json"
}
- Check Localnet Node Status: Check the status of your local network node using a command line tool such as solana-cli` or a local network manager:
solana-cli --port=8899 --node=/path/localnetworknode
Conclusion
Deploying Solana contracts on a local network can be challenging, but with these troubleshooting steps and solutions, you can resolve the issue and successfully deploy your anchor contract. Don’t forget to double-check the “.id.json” file, local network node configuration, cluster settings, and Localnet Explorer output to make sure everything is in order before attempting the installation.
By following this guide, you can eliminate common errors when deploying Solana contracts on your local network and start building scalable and secure decentralized applications (dApps) on the Solana blockchain.
