Custodialwallet

In plain words

A custodial wallet is a store of crypto assets in which the private keys are managed by the service provider. You log in with a username and password, while actual control over the keys lies with the platform. The opposite model is a non-custodial wallet, in which the owner keeps the keys and no one else has access.

Each model has its own risk logic. The custodial option is convenient: access can be recovered, there is support, and you do not have to solve the problem of storing keys securely yourself. But you depend on the reliability, integrity and solvency of the service. The non-custodial option gives full control but also full responsibility: losing the keys means losing the assets irretrievably.

A separate aspect matters for our purposes. A regulated custodial service with full client identification leaves a documentary trail: transaction history, confirmations, statements. When evidencing the source of funds this is fundamental: the bank or programme reviewer wants to see documents, not screenshots. Assets that have passed only through anonymous wallets are considerably harder to explain.
