Cross-chain on/off-ramping dApp

Developing the uRamp project for the Gnosis ecosystem was a significant challenge, addressing critical user issues like poor UX, high fees, and long settlement times when on/off ramping FIAT to crypto. This effort built on over five years of collaboration and key contributions, including work on DutchX, Omen, and the Gnosis Chain Bridge.

Together with Gnosis, we designed and built on/off ramping dApp that seamlessly handles the end-to-end operation of moving Euro from an IBAN to any ERC20 on any EVM chain and back (leveraging Monerium and Li.Fi SDK to ensure a smooth experience). The only fees that users pay are gas and bridging fees native to blockchain usage.

Users can

• create a Web3 IBAN as part of the uRamp flow and swap EUR 1:1 for EURe, the fiat stablecoin issued by Monerium, and vice versa.
• on-ramp making a SEPA transfer to (almost) any token on (almost) any network.
• off-ramp from (almost) any token, on (almost) any network to any Bank account that supports SEPA transfer.

The biggest challenge was to keep track of the whole flow (on and off ramp), connecting Li.Fi and Monerium process state, allowing the user to keep track of their transfers and resume at any step of operation.

We laser-focused on providing the best possible on/off-ramp user experience. This was our primary goal.

UX/UI design, Front-end leveraging Monerium and LiFi, improvements to the Monerium SDK, Documentation, Promotion.

dApp PoC was delivered within 1 month, MVP within 3 months.

uRamp brought in additional tx volume to Gnosis Chain.

Within the first weeks hundreds of users started exploring the app and making transfers without going through the CEX experience (account creation, long time of settlements, high fees, and slippage).

Improved Monerium SDK for a better Developer Experience.
