Developer Evangelist @arbitrum

🦇🔊

[swagtimus.eth @Swagtimus]

Some personal news:

I'm joining @arbitrum as a Developer Evangelist to help meet developers where they are and drive adoption.
I'll be working alongside my goated colleagues @hummusonrails, @aboutlo & the rest of the Arbitrum Foundation.

As some of you may know, I have a massive passion for Ethereum and have been bullish on the L2-centric roadmap ever since it was first considered.

After supporting L2 teams throughout the years and gaining experience, I believe Arbitrum has what it takes to break down barriers to adoption, offer a unified developer experience through Stylus, and make Ethereum the most accessible to developers it has ever been.

My scope of work will revolve around nurturing the vibrant Arbitrum developer community, sharing educational content on Stylus and the Arbitrum tech stack, and organizing sick regional events like OpenHouse to meet you where you're at.

The state of Arbitrum today is mindblowing, but we're not stopping there.

Arbitrum everywhere.

Why we build with Stylus 💚

We’re building RWA-backed lending, real-world assets as collateral.

That kind of protocol can’t afford inefficiency: every loan, every liquidation, every interest accrual has to run lean and fast.

That’s why our smart contracts run with Stylus, Rust contracts on @arbitrum.

Real-world assets deserve infrastructure that’s actually built for them.

Johann Kerbrat on why Robinhood is building its own L2 on Ethereum

At Consensus Hong Kong in February 2026, Robinhood launched a public testnet for Robinhood Chain, an Ethereum Layer 2 built with Arbitrum.

Following six months of private testing, Robinhood plans to launch the mainnet in 2026 and will migrate tokenized US stocks and ETFs currently offered to EU customers on Arbitrum One to its own dedicated Arbitrum-powered L2 that still settles on Ethereum.

Coinbase has adopted a similar strategy with its plans to take full control over Base’s tech stack and advance the L2 toward Stage 2 decentralization.

Robinhood Head of Crypto Johann Kerbrat explains the rationale behind building an L2:

“We can still get the security and liquidity of Ethereum, benefit from all of the work that the Arbitrum team has done, and on top of that, customize [the chain] every time we want to build something.”

He continues:

“If we want to give people access to all of the tools and elements of traditional finance, we also need flexibility [to comply with] what regulators are asking us to do. A world where you have full privacy and you can do whatever you want without KYC and trade securities is still a bit far for us. But what we are trying to find is a good middle ground. You will be on a permissionless chain. You will be able to interact with DeFi and do a lot of things with your stock tokens. We think it’s a great compromise.”

Galaxy Head of Research Alex Thorn points out that you can embed a lot of compliance controls at the application and token layers on top of Ethereum.

pretty wild how fast this industry moves

a few months ago only a few people spoke about “programmable” systems

now some of the biggest players in our industry are using language around programmable "money", "assets" etc

feels like a major signal that our industry is becoming more tradfi-friendly and institutions are starting to understand what we are all building towards and how it benefits their operations and customers - 24/7 trading, T-0 instant settlements, seamless capital flows, open access to all assets etc

I just looked up "what is the programmable economy" on google and this is what AI gave me

cool to see @arbitrum front and center powering the programmable economy

[Arbitrum @arbitrum]

Big month ahead for the programmable economy.

Fintech teams are waking up to what programmable payments, perps, RWAs, AI agents and privacy infrastructure unlock.

What are you focused on building this month?

[Arbitrum @arbitrum]

In May, the programmable economy kept accelerating across payments, stablecoins, asset tokenization and financial markets.

- Arbitrum reached 10M stablecoin holders

- Arbitrum became the busiest @USDT0_to L2 route by volume with $6.4B moved across 30,947 transactions

- @CashApp enabled send and receive USDC payments on Arbitrum

- @Ostium integrated @Nasdaq market data to power onchain stock perpetuals

- @variational_io raised $50M to aggregate RWA liquidity through RFQ infrastructure

- @Spiko_finance's EU T-Bill fund grew 5.5x to more than $374M

- @USDai_Official reached $3.6M in 365-day revenue with 297% monthly revenue growth

- @PleasingMarket's PGOLD surpassed $92M on Arbitrum in tokenized gold backed by real reserves

TL;DR: Finance is moving onchain and becoming software.

Arbitrum is the finance native platform powering the programmable economy.
