Get the only solution proving ownership of unhosted wallets and providing KYC data on unhosted wallet owners.



Understand the control, privacy, and security offered by unhosted wallets.
An unhosted, or “non-custodial,” wallet, is one where an individual user controls its private keys, rather than an exchange or trading platform. This gives users full control of their own funds, rather than requiring permission from a third party. (Examples include MetaMask and WalletConnect, or hardware wallets like Ledger and Trezor.)
- Decrypt, June 20th, 2022An unhosted wallet is not hosted by a third-party financial system. It can be very difficult or impossible to determine who is accessing or in control of the use of cryptocurrencies in an unhosted wallet. Unhosted wallets allow for anonymity and concealment of illicit financial activity.
- US Department of Treasury, December 18th, 2020.Regulators worldwide are tightening oversight on unhosted (self‑custodial) wallets. Crypto businesses are increasingly required to identify both the sender and the receiver when funds move between hosted and unhosted addresses. The goal is to reduce anonymity in high‑risk transfers and close anti‑money laundering (AML) gaps around regulated platforms.
Name and wallet or account must be captured and tied to each transfer.
Beneficiary name and receiving wallet details must travel with the payment.
Data must be accessible for sanctions screening, fraud detection, and AML investigations.
What you must collect about the sender:
Originator's full name.
Account or wallet number used to send the funds.
One identifier: address, official ID, customer ID, or date and place of birth.
What must travel with the receiving side:
Beneficiary's full name.
Account or wallet number used to receive the funds (where available).
