Bulk withdrawal for NumePay Business, a cryptocurrency payment gateway

Nume Crypto is a pre-seed startup team of 8 that aims to make cryptocurrency payments more affordable & accessible by covering transaction fees. One of their products is a cryptocurrency payment gateway for business owners. Think of it as a crypto version of PayPal – enabling business owners to accept cryptocurrency from customers as easy as credit, debit, and cash.

I designed the v0 withdrawal experience for the payment gateway, allowing business owners to withdraw their profits to more than one crypto wallet (a digital account to hold & manage funds, like a checking account). I collaborated with cofounders & engineers to understand the technical constraints behind the withdrawal process, to ensure that the experience was seamless & user-friendly as possible (for a v0).

Nume Crypto, a startup team of 8, makes cryptocurrency payments more affordable & accessible by covering transaction fees. Their crypto payment gateway lets businesses accept cryptocurrency as easy as credit or debit similiar to Paypal.

I designed the v0 withdrawal experience for the payment gateway, enabling business owners to withdraw profits to multiple crypto wallets. Collaborating with cofounders and engineers, I ensured a seamless, user-friendly process within technical limits, laying the groundwork for future iterations.

Results: In Feb 2023, Nume partnered with 5 businesses at a conference, allowing customers to pay with crypto & gather user feedback. This contributed to the company’s decision to shift towards a payment protocol, which has demonstrated better product-market fit.

Team hypothesis

Users will withdraw profits to 1 wallet

Given how niche the cryptocurrency payment market is, we did not believe there was a need to withdraw profits to more than one wallet yet.

Below is an example of what withdrawal to a single crypto-wallet would look like. A token address is required to send funds to a crypto-wallet. This is similar to a routing & account number for bank accounts.

If I have 4 different currencies, they may not be going to 1 wallet. Each currency might be going to its own separate wallet.

Current experience

1 token address for 1 wallet

Desired experience

Token address for each currency

In the desired experience, each currency has a token address field; this allows profits to be sent to multiple wallets. After conducting surveys with 300 business owners, we found 23 that accepted cryptocurrency & conducted usability tests with select users.

We learned that our hypothesis was incorrect. Users do want to be able to send profits to other crypto-wallets to better manage their profits. Learn more about types of crypto-wallets

Problem

Withdrawal process is tedious

The current experience forces a user to go to another platform to distribute their funds as opposed to doing it at once during the withdrawal process in NumePay Business.

2 step withdrawal process

Step 1

Copy & paste crypto wallet info

Think of this step as providing the account & routing numbers for a checking account.

A token address has 42 characters & is a unique identifier for your wallet. For more information, you can check out Metamask's page.

Copy & paste crypto wallet info

The first step is to copy & paste token addresses connected with your crypto-wallets. Think of it as providing the account & routing numbers for a checking account. A token address has 42 characters & is a unique identifier for your wallet. For more information on token addresses, you can check out Metamask's page.

In this example, a user is using the Coinbase wallet browser extension to copy & paste their token address into NumePay Business.

Step 2

Verify token addresses

Users need to review everything carefully to ensure profits are being sent to the correct wallets.

Once funds leave the platform, users are fully in control & responsible for funds (self-custody of funds). This means users risk the potential loss of funds during the withdrawal process.

Here, users need to review everything carefully to ensure profits are being sent to the correct wallets. Unlike traditional banks, Nume cannot compensate for money loss if funds are sent to the wrong place. Once funds leave the platform, users are fully in control & responsible for funds (self-custody of funds). With self-custody, users risk the potential loss of funds during the withdrawal process.

Impact

Partnered with 5 local businesses for a soft launch to gather user feedback

My internship ended in July 2022 before any MVP testing was conducted on this experience.

In Feb 2023, Nume partnered with 5 local businesses to conduct a closed alpha launch at a web3 conference.

This event provided an excellent opportunity for business owners to expand their payment options & gain firsthand experience in accepting cryptocurrency.

While the specific results of the launch remain proprietary, Nume Crypto has since shifted its focus to offering users a protocol that aims to facilitate affordable cryptocurrency transactions.

Although my work might not have been publicly launched yet, it has played a significant role in helping Nume Crypto move closer to finding product-market fit and achieving their mission of making payments more affordable and accessible for all through the utilization of web3 technology.
