<p>The primary aim of this integration is to safeguard mobile users from the increasingly common threat of SIM swap fraud. This type of fraud involves attackers unlawfully transferring a victim’s phone number to a SIM card in their possession. This enables them to bypass security measures like two-factor authentication (2FA) and gain unauthorized access to sensitive personal and financial information.</p> 
<p>By utilizing Chainlink Functions, Telefónica’s <a href="https://www.altcoinbuzz.io/?s=smart+contract" target="_blank" rel="noopener">smart contracts</a> can now automatically verify any changes made to a user’s SIM card information. Flagging unauthorized swaps and potentially preventing fraudulent activities.</p>
