// broadcast
const res = await rest.cosmos.tx.broadcastTx(sdk, {

console.log(res);

});
});
Use starport to test.
The first digit major version and the second digit minor version should match Cosmos SDK. The third digit patch version can be independently incremented.

Security News
Floating dependency ranges in npm can introduce instability and security risks into your project by allowing unverified or incompatible versions to be installed automatically, leading to unpredictable behavior and potential conflicts.
Security News
A new Rust RFC proposes "Trusted Publishing" for Crates.io, introducing short-lived access tokens via OIDC to improve security and reduce risks associated with long-lived API tokens.
