Definition
A self-hosted wallet, also called an unhosted or non-custodial wallet, is one in which the user holds their own private keys directly, outside any exchange or regulated platform. In regulatory language this is the counterpart to a hosted wallet, which is controlled by a third party such as a VASP that can access and move customer funds. Examples of self-hosted wallets include hardware signing devices and open-source software wallets where no intermediary ever takes custody.
How regulators treat it
Because no third party controls the funds, a self-hosted wallet generally sits outside the licensed financial perimeter, and the individual holder carries no AML or Travel Rule obligations. The regulatory attention instead falls on the regulated firms that transact with these wallets. Under FATF guidance, when a VASP sends to or receives from a self-hosted wallet, it should collect and retain the counterparty's name and wallet address, but it need not transmit or independently verify that data, since there is no counterparty institution on the other side.
Why it matters for sovereignty
Self-custody is the technical foundation of financial sovereignty: holding your own keys means no operator can freeze, lend, or lose your coins, and no custodian solvency question applies. Proposals in various jurisdictions to tighten reporting on transfers to self-hosted wallets are an ongoing area of debate, because they sit at the friction point between surveillance objectives and the right to hold bearer assets.
