Lately, I’ve been seeing more and more that developers are beginning to realize: complete dependence on Ethereum when creating payment applications is not exactly the right approach. The community is increasingly discussing how to go beyond the usual frameworks of traditional ecosystems and architectures.

The point is that there is a need for payment applications that work with both blockchain and traditional financial systems simultaneously. The main goal is to ensure smooth onboarding and withdrawal of funds so that users don’t feel friction when transitioning between worlds.

What exactly is being proposed? First, move away from standard 0x addresses for regular transactions. Use them only for one-time deposits — this reduces dependence on the traditional address scheme. Second, for internal payments, focus on solutions oriented toward privacy. Railgun and Aztec specifically address this issue, allowing transaction details to be hidden.

It seems to me that this indicates a broader trend: dependence on a single ecosystem becomes a bottleneck. Developers are looking for hybrid approaches that combine the convenience of traditional payments with the advantages of blockchain. And it makes sense — if you want mass adoption, you need to think not only about Ethereum but about the entire spectrum of interaction with fiat and privacy.
