If you built a custom wallet and act as your own provider, CARF likely wouldn’t apply to you directly. CARF targets Reporting Crypto-Asset Service Providers, such as exchanges and third-party wallet providers, not individuals managing their own wallets.

However, any interaction with a CARF-covered entity (e.g., sending funds to an exchange) would still be reported by that entity. You may still be required to self-report your transactions and holdings to comply with tax laws in your country.

While CARF doesn’t currently target self-hosted wallets, I believe regulators could look to close gaps.
