Which Bitcoin wallet has no transaction fee?

Could you please clarify which Bitcoin wallet, if any, currently offers the feature of no transaction fee? It's important to note that transaction fees are a crucial part of the Bitcoin network, as they help incentivize miners to process and validate transactions. However, some wallets or exchanges may offer fee discounts or promotions at certain times, or have built-in mechanisms to optimize fee usage. But to my knowledge, there isn't a widely-used Bitcoin wallet that completely eliminates transaction fees. Is there a specific reason you're looking for a wallet with no fees, or are you simply curious about the options available?
