creating a custom spl token 22

Question

hey i made a custom keypair and want to make a custom contact address like my keypair. then I spl-token create-token and entered my keypair json and I got this "Error: "default signer is required, please specify a valid default signer by identifying a valid configuration file using the --config argument, or by creating a valid config at the default location of ~/.config/solana/cli/config.yml using the solana config command"" any idea how to fix

Answer 1

This is a common error that you'll see across Solana and SPL tools unfortunately. If you don't have a default keypair configured, the commands will abort.

In your case, you need to specify some keypair to pay for the transaction to create the token. You can do this with:

solana-keygen new

And then funding your new keypair with an solana airdrop or by transferring SOL to it.

Answer 2

Try this:

Step 1:

solana config set -k <path/to/your/mint/authority/keypair>.json

Step 2:

solana airdrop 1

Step 3:

spl-token create-token <path/to/your/desired/mint/keypair>.json

The mint address should now be whatever the pubkey of your desired/mint/keypair is.
