Designing a Truly Non-Custodial Payment System

Nebula was built around one core principle: user funds must never be held by a third party. From the start, we designed our payment flow to move assets directly between wallets using smart contracts for verification and automation. This ensures full transparency, eliminates custodial risk, and aligns with the core values of decentralization.

Eliminating Custody Risk

Unlike traditional crypto gateways, Nebula never touches merchant or customer funds. Every transaction is executed on-chain, with payments flowing directly from sender to recipient. This architecture guarantees ownership, improves trust, and removes a major attack surface in payment systems.
