Arbitrum has a strong ecosystem of lending, trading, and yield protocols but most new users still need to go through a CEX before they can interact with any of them. A native fiat on-ramp layer could meaningfully expand the addressable user base for protocols building on Arbitrum.
The Problem Today a user interested in any Arbitrum protocol, whether lending on Aave, trading on GMX, or earning yield on Pendle, must first acquire assets via a centralized exchange, bridge or withdraw to Arbitrum, and only then interact. For crypto-native users this is routine. For everyone else it’s enough friction to prevent participation entirely.
This isn’t a protocol-level problem, it’s an ecosystem-level one. No single Arbitrum protocol can solve it alone, but solving it at the infrastructure level benefits the entire ecosystem.
Who This Unlocks
Retail users in Europe and Brazil who are fintech-native but not crypto-native
Treasury managers and SMBs exploring on-chain yield on idle capital
Freelancers and remote workers in LatAm receiving stablecoin payments who need fiat in/out
One Possible Approach Fiat on-ramps that route directly into on-chain positions via DEX liquidity already exist and are live on Arbitrum today. These can be integrated at the frontend level by individual protocols, no chain-level changes required. Compliance is handled at the fiat-to-stablecoin layer by regulated partners.
Questions for the Community
Is fiat accessibility a priority the Arbitrum community wants to address at the ecosystem level?
Which protocols or user segments would benefit most from a native fiat entry path?
Are there existing initiatives in this space the community is already aware of?
Really appreciate this post and I generally agree with the framing that “fiat access = ecosystem‑level growth lever” rather than a single‑protocol concern.
Speaking from India, I see this problem very clearly with non‑technical users and even small businesses:
They almost always need to “hire a guide” (a friend, agency, or some local expert) just to navigate CEX → stablecoin → bridge → Arbitrum → DeFi.
This makes the whole experience feel like a high‑friction, high‑trust dependency on an individual, instead of a reliable and simple product experience.
As long as the ecosystem is not flexible enough to meet users where they are (fiat, local rails, simple UX), new users will not truly “belong” to Arbitrum — they will just be passing through, if at all.
From a competitive standpoint, if another ecosystem can offer smoother fiat → on‑chain → DeFi flows with less reliance on intermediaries, Arbitrum risks losing the next wave of users who are not crypto‑native and don’t want to learn complex bridging flows.
A few questions I’d love to see explored further:
How do we make sure this does not become over‑dependent on a single fiat partner or geography?
Can we design KPIs around “new to on‑chain” users onboarded via fiat rails, instead of just volume?
Is there a path for Arbitrum to treat this as public‑goods‑like infra, so protocols can plug in and focus on product rather than recreating the same rails?
As a DAO governance researcher working on protocol risk and multi‑chain governance, I’d be happy to contribute more context from the India / non‑technical user side if that’s useful.
This is definitely a gap worth closing. Fiat access is still one of the biggest bottlenecks for onboarding non-crypto-native users, and solving it at the ecosystem level would unlock real growth across Arbitrum DeFi.
I believe Anywhere Payments, coming out of the last hackathon, has built/is building in this direction. Worth looking into for your starting point.
Thanks for confirming that this is indeed a gap worth closing. That gives a lot more confidence to explore this as “public‑goods‑like infra” rather than just a nice‑to‑have UX layer for a few protocols.

I’ll dig into Anywhere Payments as a starting point and try to map how a more standardized fiat → Arbitrum → DeFi flow could look for different user profiles (retail, SMB treasuries, freelancers, etc.), especially in markets like India where the “hire a guide” pattern is still the norm.

If there’s interest, I’m happy to come back with a short note or draft framework that the community can react to, so this doesn’t stay at the level of just “we all agree this is important” but moves toward something concrete. @EmmanuelO
Hey everyone, PendulumAlex here from the SatoshiPay team. This thread describes exactly what we’ve seen across various ecosystems that “fiat-to-wallet” is only half the battle. We’ve been building out a Direct-to-Protocol ramping feature with the project Vortex (vortexfinance.co).
It is an on/off-ramp that routes directly into on-chain positions via DEX liquidity or smart-contract interactions, that are abstracted away from the user. Instead of the CEX → bridge → deposit flow, users pay via bank transfer and land directly in a protocol position in one step. Fee range is 0.25–1.25%, gas abstracted.
We’re live on Arbitrum and looking for a protocol to run a pilot with, specifically teams seeing drop-off at the deposit stage. Happy to chat if that’s you.
