I'm suggesting that _you can try brute-forcing the missing word in your Phantom wallet's mnemonic seed phrase using a tool like BTCrecover_. Since the wallet is BIP39 compatible, the last word of the mnemonic recovery words embeds a checksum, which limits the number of possible solutions. By using BTCrecover and providing an address associated with the wallet, you may be able to recover the missing word and regain access to your wallet. Additionally, _learning about derivation paths and HD wallets_ can help you better understand the recovery process and increase your chances of success.
