# Common Issues / FAQ ### FAQ ### Common Issues #### Why am I getting issues with nonce errors? State changing functions such as `energize()` do not wait for confirmations before returning. Ethereum uses nonces to prevent attacks on the network, so sending too many transactions without waiting for confirmations may lead to nonce errors. ```javascript // Get the transaction const tx = await nft.energize(...); // Use wait() to sleep the thread until the transaction has confirmations const receipt = tx.wait(); ``` --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
