ePayMe
A digital payment platform for fast, secure, and cost-effective on-ramp transactions.
The Challenge
- Users needed a straightforward way to convert fiat to crypto without leaving the site
- Exchange rates had to stay accurate to the second while the order was being placed
- Wallet address validation needed to prevent costly, irreversible user mistakes
- Partner integrations required flexible webhook-based settlement notifications
Our Solution
Streamlined on-ramp flow
A single-page buy/sell flow quotes live rates, locks pricing for the transaction window, and confirms wallet addresses before funds move.
Rate engine
A dedicated pricing service aggregates multiple liquidity sources and republishes rates to the client on a short refresh cycle.
Partner webhooks
We built a webhook dispatch system so partner platforms receive real-time settlement and status updates without polling.

Overview
Overview
ePayMe's goal was to be the world's most economical on-ramp gateway, letting users buy and sell crypto with minimal friction. Albos Technologies Pvt Ltd designed and built the transaction flow and its supporting infrastructure.
The challenge
On-ramp transactions are unforgiving of mistakes: a mistyped wallet address or a stale exchange rate can mean a user permanently loses funds. The team also needed a way for partner platforms to receive settlement updates without constant polling.
Our approach
We built a single-page buy/sell experience with address validation, rate locking during the transaction window, and clear confirmation steps before funds move. A rate engine aggregates pricing from multiple liquidity sources, and a webhook dispatch system pushes real-time settlement events to partner integrations.
Results
ePayMe now completes most transactions in well under a minute, with a high successful settlement rate, zero wallet-address related fund losses since launch, and a meaningful drop in support tickets tied to failed transfers.
