What is the Travel Rule and Who It Applies To

The Travel Rule is an international regulatory requirement aimed at increasing the transparency and security of financial transactions.

It requires financial institutions and Virtual Asset Service Providers (VASPs) to collect and transmit certain information about the sender and receiver of cryptocurrency transactions to prevent money laundering and terrorism financing.

What is AOPP and Why It’s Needed

Address Ownership Proof Protocol (AOPP) — a protocol that automates wallet ownership verification.

Advantages:

• Verification without screenshots or manual data entry
• Cryptographic signature in the wallet as proof of ownership
• Secure data transmission along with the transaction

Preparing for Verification

Before verification, prepare:

• Wallet address in the required network
