Request Pre Screening with asset and address information
By delivering the virtual assets and wallet address, VASPs can verify the risk of the wallet address.
It is recommended to pre-verify with Pre Screening API before the verification request.
Pre Screening API is used to check the risk level of a wallet address by enclave before virtual asset transaction. Internally, a Chainalysis service is used.
Application: When a user requests withdrawal, the originating VASP can check the risk level of the wallet address of a beneficiary prior to the originating VASP's /verifications or vice versa.
In a staging environment, Pre Screening API is free of charge for 2 weeks.
