End-of-Lesson Summary

You have learned that

• Transactions are composed of clauses (instructions).

• VTHO estimation is a mandatory step to ensure you have enough gas.

• Transactions must be signed by a signer before submission.

• The Transaction Receipt provides the final execution status and logs.

• The network now operates on Delegated Proof of Stake (DPoS).

Congratulations! You can now build a full transaction lifecycle from encoding a function call to tracking its successful execution on-chain.
