Example code to verify a signature
This is an example app that shows how to verify a signature signed by an account key.
Inputs to the app are:
- signature - bytes represented as a hex string
- public key - in JSON format (you can query any Cosmos chain for account's public key as JSON, however it will need to have sent a signed transaction to the chain for this to be present)
- message - the string message to verify
Running locally
Run the example by changning to this directory and running:
cargo run
And you should see the output:

Verify the correct message:
SUCCESS ✅ signature is valid
Verify the correct message with the wrong address:
FAILURE ❌ signature is not valid: account id does not match
Verify the correct message with the wrong account and public key:
FAILURE ❌ signature is not valid: account id does not match
Verify another message:
FAILURE ❌ signature is not valid: signature error - signature error
