Settlement Ramp

Demo

About

The problem it solves Before the project, people struggled with: - **High fees (10-15%+) and multi-day delays** when trying to convert USD received in PayPal into local currency or, more importantly, into on-chain stablecoins like USDC. This effectively trapped their funds in a "PayPal Prison." - **Blocked access to the on-chain economy**, preventing them from easily participating in DeFi, global crypto commerce, or using stablecoins for efficient treasury management. - **A lack of modern, developer-friendly financial infrastructure** in LATAM to seamlessly connect widely-used international payment platforms (like PayPal) with blockchain networks like Base. This created significant friction for on-ramping.

How it's made

Challenges we ran into Building Settlement Ramp within the hackathon demanded intense focus and adaptability. Our primary challenge was maintaining a problem-first approach, resisting the urge to over-engineer before confirming we were directly solving the core user pain: the high friction of moving PayPal funds to on-chain stablecoins in LATAM. This discipline guided us to prioritize a streamlined PoC demonstrating the core bridge mechanism. Time management was a constant battle. Integrating PayPal Sandbox, ChainSettle, Base Sepolia, and a frontend under a tight deadline required ruthless prioritization. We focused solely on getting the fundamental off-chain attestation and contract deployment functional, deferring full USDC liquidity implementation for a future phase to ensure we delivered a tangible, working component. Integrating with Circle for native USDC was an ambitious goal exceeding hackathon scope. Instead of getting blocked, we pivoted to a simplified USDC settlement mechanism for the PoC – planning for the contract to manage a pre-funded reserve. This strategic deferral allowed us to prove the on-chain settlement concept without the full complexity of a financial API integration under pressure. Finally, the reality of local LATAM bank ramps being often closed systems presented a significant hurdle for immediate integration. To validate our bridging architecture quickly, we pragmatically chose PayPal as a more accessible initial PoC. This allowed us to demonstrate the core off-chain to on-chain attestation and settlement logic, creating a blueprint adaptable for integrating more complex local rails as Equilibrio evolves. Each challenge forced us to make tough, but necessary, calls to prioritize execution and deliver a focused solution.
