1. solana-keygen new --outfile solana/my_wallet.json --force

3. solana airdrop 2 0xxx.... 0xxxx [and get sufficient balance upto 10 sol]

4. anchor build

5. solana address -k target/deploy/my-keypair.json

6. Copy programId and updated my Anchor.toml file as well as Lib.rs file [declare_id]

7. Set cluster and programs to de.net in Anchor.toml file

8. anchor build

9. I updated programId in idl file as well.

10. anchor deploy --provider.cluster de.net

How to resolve this issue?

Answer 1

• this might be one issue

  solana address -k target/deploy/my-keypair.json

file name should include your contract name. this is the syntax

yourContractName-keypair.json

• you should also add this to anchor.toml

   cluster = "de.net" wallet = "./my_wallet.json"

Answer 2

It looks like you're using the Public RPC. One possible cause of this issue is that the public de.net RPC is overloaded.

You might want to try a private RPC. You can try using a service like Quicknode , which has private Solana de.net RPCs and a free tier you can use for this purpose.

Then, once you have the URL to your private node, you use:

solana config set --url https://quicknode.com.....{insertrestofurl}
