[_Portal_](https://bit.ly/3GHmqnz) _is a fast, flexible, and secure MPC wallet-as-a-service and key management platform. Portal helps Web3 and enterprise companies scale blockchain operations, move stablecoins globally, or create thousands of Web3 wallets._

**Customer Highlights**

[**Meru Expands Access to Crypto with Portal Integration**](https://bit.ly/3GswNM5)**:** Meru, a leading LATAM fintech, partnered with Portal to integrate secure, mobile-first Web3 wallets into its app—giving users access to US dollar accounts and decentralized finance without sacrificing self-custody. Thanks to Portal’s mobile SDK and Flutter compatibility, Meru expanded its offerings while keeping the experience seamless and familiar for users.

[**Dwinity Taps Portal for Secure Data Sovereignty**](https://bit.ly/3GwQtyA)**:** Dwinity is building a data economy where users control and monetize their personal information without giving up ownership. By integrating Portal’s MPC wallets, Dwinity ensures enterprise-grade security, true user sovereignty, and seamless identity management through decentralized tech.

[**Loula Powers Cross-Border Payments with Portal**](https://bit.ly/4iCFvon)**:** Loula enables businesses to send and receive payments globally by combining traditional banking reliability with the speed of stablecoins. With Portal’s secure APIs, Loula built a non-custodial, user-friendly solution that lets clients manage USDC wallets without ever touching private keys, streamlining international trade across LATAM, the U.S., Europe, and Asia.

**Product Updates**

[**Signature Approval Webhooks Now Available**](https://bit.ly/3Gwit5e)**:** Take full control of your Portal signing requests.

We’re excited to launch **Signature Approval Webhooks**, giving you real-time control over transaction and message signing. With this new feature, your server receives an instant webhook whenever a Portal client initiates a signing request—allowing you to approve or block it based on your own custom logic.

**Key benefits:**

*   **Real-time alerts** for every signing attempt
    
*   **Enhanced security** with webhook secrets, HTTPS enforcement, and IP allowlisting
    
*   **Flexible integration** with easy setup via the Portal Dashboard
    

Ready to unlock real-time control? [Contact our team](https://bit.ly/43edqOL) to enable Signature Approval Webhooks and get started today. Learn more in our [docs](https://bit.ly/44O78rh).

If you’re in Brazil for [Web Summit Rio](https://bit.ly/42ygnuh), our CEO, Raj Parekh, would love to connect. Raj will speak on a panel about why stablecoins are outpacing traditional finance in speed, cost, and security. He’ll be sharing the stage with representatives from Bridge and MetaMask discussing real-world case studies: stablecoins in remittances, B2B payments, ecommerce, and more.
