How OneSafe enabled global transaction verification in just one day with Prelude

OneSafe is a neo bank offering crypto-friendly bank accounts for global businesses. With over $200 million in transaction volume and a client base of 400 businesses, OneSafe is dedicated to serve the rapidly evolving Web3 market.

Founded by Chris Shei and Brian Ko, OneSafe enables crypto native businesses to create virtual cards and manage company expenses.

Verifying financial transactions globally and seamlessly

As OneSafe is onboarding more businesses and growing their user base with seamless banking experiences, they needed to find a solution for verifying user transactions through One-Time Passwords (OTPs).

Whenever an employee of a OneSafe client company needs to buy something online, OneSafe must verify the identity of the buyer before authorizing the transaction. This helps businesses to protect their spending and OneSafe to prevent fraud and phishing attempts against their customers.

However, in order to achieve this, they needed a fast, reliable, and global solution for verifying user transactions that wouldn’t keep their users waiting forever to receive a code.

Before discovering Prelude, OneSafe was using other providers for OTP verifications, but found the setup process too slow and cumbersome. For a company focused on quick scalability and global reach, the need for simpler and faster implementation became a priority.

"Before Prelude, we used Twilio and AWS, but it was taking forever to get set up on other platforms. We wanted something simpler and quicker, and most importantly global”, added Chris Shei.

Fast-tracking the user verification process with Prelude

A quick and seamless implementation

Prelude quickly became OneSafe's preferred solution for handling OTP transactions due to its simplicity and efficiency.

OneSafe was able to implement Prelude API in just one day, avoiding the delays and complexities they had experienced with previous providers. Not only was the technical set up quick, but they were also able to send OTP messages on day one.

In many countries, regulators and mobile operators require documentation to ensure that businesses sending SMS comply with local laws and guidelines, to prevent spam and phishing. Companies need to send a Letter of Authorization (LOA) as a formal request to the telecom provider to allow them to send SMS messages to users in that country. For certain regions, sending SMS without the necessary authorization could lead to blocked messages or fines.

This is a process that requires some manual work and can take from a few days to several weeks.

However, Prelude is registered worldwide with all providers so you can start sending OTP right away. Our message templates are pre-approved and optimized for conversions, to help our customers start verifying users as fast as needed.

OneSafe was able to send OTP messages to customers globally on day one, without having to go through lengthy country-specific setups.

By removing the operational friction involved in SMS delivery, OneSafe could immediately focus on scaling its user base and expanding its transaction volume without worrying about the technical logistics of OTP messaging.

A reactive customer support

A key differentiator for Prelude was its reactive customer support. OneSafe needed to tailor the creation process of the OTPs, and Prelude support team made that possible.

"We had specific requirements for customizing the OTP, which meant making direct adjustments to their API. When Prelude came back the next day saying the changes were already implemented, I honestly thought they were joking—it was that fast! Their support team has been incredibly responsive whenever we've had questions, making the whole process smooth and efficient" shared Chris Shei.

This high level of responsiveness that they didn’t have with their previous providers ensured that OneSafe could continue operating at full capacity with minimal disruptions.

A global and reliable delivery

With Prelude, OneSafe can now send OTPs anywhere in the world, ensuring a near-perfect delivery rate. Prelude’s API connects OneSafe to 30 carriers and 4 messaging channels across 230 countries, enabling them to verify transactions swiftly, regardless of their customers' location.

Prelude's smart-routing technology guarantees that OTP messages reach the intended recipients efficiently, with instant fallback options to alternative routes if needed. This has enabled Prelude customers to achieve an industry-leading conversion rate of 95%.

By partnering with Prelude, OneSafe has significantly improved its OTP verification process. From the quick setup to seamless global delivery and customized support, Prelude has enabled OneSafe to scale its operations without being bogged down by technical challenges.

"Prelude is a great solution to send OTPs globally and seamlessly. We were able to send messages from day one and didn’t need to do all the usual paperwork with each country to get set up," Chris added.
