Sign Messages

Install the CLI and sign in. Replace the example account ID, session-key ID, and recipient with your own. Use an active key installed on Base Sepolia with permission for the operation.

The key must allow message signing on that network. Transfer-only permissions are not sufficient.

The command does not broadcast a transaction. The signature is for the smart account, not a plain externally owned account signature.

Use --output json when passing the signature to another application:

namera --output json sign \
  --namespace evm \
  --wallet 0199dfe1-0000-7000-8000-000000000001 \
  --session-key 0199dfe1-0000-7000-8000-000000000002 \
  --network 'Base Sepolia' \
  --type message \
  --message 'Hello from Namera'

This is another signing operation, not a read of the previous result. Choose the output mode before signing rather than rerunning just to change formatting.

Keep the original message, account, and network with the signature. Use Verify Signatures to check it. The fixture signature shown here is illustrative, not a signature to reuse.

Example output uses fixture accounts and hashes, captured with the CLI's output formatters. Plain-text output is shown without terminal colors; your values and relative expiry dates will differ.
