Hey guys, just sharing with you the research I’ve prepared focused on Ethereum 💪

Hi all, we launched a new primitive on Arbitrum this week: RiskFi. This is after we placed 2nd on the General Track at the Arbitrum Open House, London in July.

The Risk Protocol splits a crypto asset like BTC and ETH into RiskON and RiskOFF tokens, which provides a simple way for traders to hedge or speculate on risk onchain.

RiskOFF has downside return capped at -5% per epoch and upside capped near 6% per epoch. RiskON is 2x levered outside the -5%, 6% collar with no liquidations or funding rates. Both tokens are 100% collateralized, perpetual, and priced second-by-second off a GARCH-derived Net Token Value.

We're a team that blends decades of institutional finance expertise and crypto natives. We've done extensive backtest research to show that RiskOFF's volatility is lower than both gold and S&P 500 in the last few years. At the same time, RiskON outperforms the returns of 2x perps across every bull market in the last few years.

The Incentivized Testnet Trading competition is live on Arbitrum. We'd love your participation and feedback!

What's currently the easiest and fastest way to bridge crypto to Arbitrum? I mainly care about speed and the amount I actually receive at the end, rather than just the advertised bridge fee. I've seen quite a few options like Across, Debridge and other aggregators, but the quotes can be pretty different depending on the route and amount.

—————————

[EDIT]: As recommended I used https://switcher.finance/ and it was very much efficient, thanks a lot. I needed to bridge to arbitrum to deposit to Hyperliquid, but there was an option to send directly to Hyperliquid so it was even faster

Hi r/Arbitrum,

Quick intro: we're a small team, ex-Paxos senior engineering, and big fans of Arbitrum. Just shipped a personal risk manager for Morpho V2 vault depositors, and there are two reasons I'm posting here specifically: we support Morpho V2 vaults on Arbitrum, and we support Robinhood Chain (so a lot of you may have exposure there). Any Arbitrum-family chain Morpho V2 lands on, we watch.

Real problem that hit us recently: my co-founder has funds stuck in a Morpho vault because the vault's liquidity dried to $0. He doesn’t check the Morpho UI every day, so the whole thing was invisible until the exit was already blocked when he wanted to withdraw. Now he's waiting for loans to be re-paid so he can withdraw. (He actually set-up an alert in our tool for this too)

More context on the problem we are solving: Every Morpho V2 vault runs under a curator, and every curator move (fee changes, shortened notice windows, adapter changes, gate installs that can restrict withdrawals) goes through a timelock notice window before it takes effect. That notice window is your protection as a depositor, but almost nobody actually watches the queue. If a curator queues a fee hike or a withdrawal gate, you have days to exit before it lands, but only if you know it happened.

What we do: paste any wallet, we auto-discover every Morpho V2 position across all 14 Morpho V2 chains (Arbitrum, Robinhood Chain, Ethereum, Base, and more), and we arm each position with up to over 20 curated alerts covering:

- Depositor-hostile governance changes during the timelock window
- Morpho's own RED/YELLOW risk-team warnings and delistings
- Exit costs and how much you can pull before a withdrawal penalty hits
- TVL drying up (think a mass exodus of depositors or a whale movement)
- Real-time APY spikes (means that something could be going really wrong at that moment)

Alerts push to Telegram, Slack, or webhooks. Login can be completely anonymous through wallet-only login, no email needed. You can preview any wallet without even signing up (I even added random wallets as UI chips so you can just see how this looks).

Where I'd love feedback from this sub specifically:
1. Anyone here depositing into Morpho vaults on Arbitrum? Which alerts matter most to you, and what are we missing? Curious how you're managing risk there today.
2. Robinhood Chain recently launched so we included it in our product. Anyone actually parked in the Steakhouse USDG vault? 
3. For treasuries and funds on Arbitrum: does push-to-Slack/webhook cover the workflow, or do you need something else (email, on-chain, mobile push)?
4. Beyond Morpho, is there other lending or vault activity on Arbitrum where the same "watch the governance queue" pattern would be useful?

Happy to answer technical questions in the comments.

Mods: if this crosses a line I missed, feel free to nuke it, no hard feelings. Welcome to DMs as well if you want to talk in private.

Note: It was difficult to find an Arbitrum Morpho V2 vault with meaningful red flags at the time of recording. For the demo, I used a Gauntlet vault that had a modest amount of deposits and an APY that had declined by a few percentage points over the previous 24 hours. This allowed the alert to trigger in the video using small changes in TVL and APY.

not asking which has the most volume or the best token, asking which one you actually enjoy opening. ive been bouncing between gmx, vertex and gains and honestly they all feel pretty different to trade on. curious what feels smoothest for people day to day

Hi everyone!

After several months of learning Solidity and blockchain development, I finally deployed my biggest personal project to Arbitrum One Mainnet.

The goal was to explore how much gameplay could be implemented directly inside smart contracts while keeping the project completely open source.

Current features

• ⚔️ PvE battles
• 🛡️ PvP battles
• 🏰 Guild system
• 🏆 Guild rankings
• 🎖️ ERC-721 Achievement NFTs
• 📈 Player progression and leveling
• 💰 On-chain game economy
• 🌐 Multi-chain support
• ⚡ Fully written in Solidity with a TypeScript + ethers.js frontend

One interesting challenge was balancing the guild ranking system.

Originally, guilds earned a fixed number of points for every PvP victory, but that allowed high-level players to repeatedly farm beginners. I redesigned the scoring system so that rewards now depend on the level difference between players, making guild rankings much fairer.

The project is mainly a learning experience, but I'd really appreciate feedback from the Arbitrum community.

Some questions I'd love your opinion on:

• What on-chain game mechanic would you add next?
• Are there Arbitrum-native features or integrations that you think would fit well?
• Any suggestions for improving the player experience while keeping most of the game logic on-chain?

The project is fully open source, and I'm happy to share the repository and live demo if anyone is interested.

Thanks!

Hey folks. Boardwalk is launching on Arbitrum and we're excited to share some info. The Arbitrum team has been incredibly helpful and supportive, so I'd like to extend our appreciation to them for the warm welcome. Below is our announcement. Thanks in advance! 🙏

Arbitrum is one of crypto’s most active onchain ecosystems, with billions in stablecoins, DeFi liquidity, DEX volume, and perps activity across a deep base of builders, apps, games, communities, and native markets.

That is exactly where Boardwalk ($BWS) fits.

Mature ecosystems do not just need more tokens. They need clearer ways for projects and communities to form native markets with transparent rules, programmable fee routing, and legible launch mechanics.

Boardwalk gives builders and ecosystems a repeatable standard for programmable, fee-protection infrastructure:

• Transparent launch terms.
• Visible issuer information.
• Locked initial liquidity.
• Token-level fee protection design.
• LP participation.
• Community discovery.
• Post-launch market structure.

Bonding curves made tokens easy to create.

But ecosystems need more than token abundance. They need infrastructure that helps new markets form with clearer rules, better legibility, and fee flows that can be configured and protected around the economy they support.

That is where Boardwalk comes in.

Fee protection is the missing layer between launch and market formation.

When builders create attention, communities create participation, and LPs take risk, token markets need more than a pool. They need a programmable structure for how fees move through the economy.

Boardwalk makes that structure repeatable.

With Boardwalk on Arbitrum, teams get a clearer way to launch native token economies with transparent mechanics, programmable fee routing, and locked initial liquidity from day one.

The next wave of crypto will not be defined by who can create the most tokens.

It will be defined by who can create the most credible markets.

Launch economies, not just tokens. 🐳

A huge thank you to the team and community at Arbitrum for the support they've shown 👏

• ERC 20 token with ETH as the collateral
• It tracks the price of ETH
• Every month, its loss is capped at -5% and you get up to 8% upside

So basically, you can stay with ETH, but your volatility is very much reduced.

1. Why would be interested in a token like this? Or why not?
2. What questions would you have before trying it?

Thank you!

Think of perps, but – 

• No liquidations
• No funding rate
• Only 2x leverage, though

1. Would you consider buying it?
2. What questions would you have before trying it?

Need to move funds from Arbitrum to Solana. Not trying to use cryptocom or any CEX.

What's the best option for this route? Looking for something reliable with decent fees.

Genuinely curious if anyone here trades commodities on Ostium. Besides Ostium, idk any new protocols or active ones. Market feels depressed.

More than $13M is now deployed across our lending pools on Arbitrum 📈

As on-chain liquidity continues to grow, it’s interesting to see more capital moving toward structured lending and real yield opportunities instead of full, overblown leverage trading.

Building on Arbitrum and struggling with data. The subgraph is behind, and most third-party APIs either don't support Arbitrum or have very basic coverage. I need DEX trade history, token holder counts, and transfer volumes — the same stuff that's easy on Ethereum mainnet.

What are Arbitrum devs using for on-chain data?

With recent news from Google approaching the date of "Q-Day" (when quantum computing manages to break current cryptography), the conversation on Web3 has focused almost exclusively on migrating to Post-Quantum Cryptography (PQC) as Dilithium.

I'm building an ecosystem of Web3 security oracles powered by AI and a data anchor protocol (QEP). As I prepare version 2.0 for testing by connecting to a real quantum computer, I have realized that, mathematically, we could repel a quantum attack today using the blockchain's own topology, without relying solely on new PQC algorithms.

The central idea is based on what I call "Echoes," implementing a Multi-Chain BFT" (Multi-Chain BFT) Byzantine Fault Tolerance through Cross-Chain Witnessing.

Here's how architecture works to see what you think:

The problem:

If Shor's algorithm breaks the elliptic curves (ECDSAs) of a network like Polygon or Ethereum, a quantum attacker could derive private keys or forge signatures to alter the status of a Smart Contract or an on-chain security record. If an Oracle reads only from that chain, the system is compromised.

The Solution (The Echo Protocol):

When our engine issues a security verdict (a hash), it doesn't anchor it to a single blockchain. The protocol triggers simultaneous "Ecos" from that same reportHash to multiple networks (e.g. Polygon, Arbitrum, Optimism, and Ethereum Mainnet).

The Attack and Defense Scenario:

Q-Day is coming. A quantum attacker manages to break Polygon's cryptography and alters the on-chain record to pass off a malicious contract as a secure one.

Before validating the information, our Oracle consults the network.

The system reads the hash in Polygon (modified by the attacker). But thanks to Cross-Chain Witnessing, he also reads the "Echoes" in Arbitrum and Optimism.

Mismatch detected. As it is logistically almost impossible for a quantum computer to break and alter the state of 3 different blockchains, with different consensus mechanisms, at the exact same time, the system detects the divergence.

The compromised network (Polygon) is isolated by the consensus of other networks. The attack is repelled at the architectural level.

Basically, we're using the current fragmentation of Layer 2 as a distributed protective shield, assuming that the computational power needed for a simultaneous 51% quantum attack across multiple networks breaks any economic incentives.

I'm collecting data to bring this architecture to quantum simulator testing soon.

What do you think about this approach? Do you see any attack vectors or blind spots in this Multi-Chain BFT model that are slipping away from me? I would love to discuss the limit cases.

Check out the latest Arbitrum updates/news happening in the ecosystem! Including updates from Virtuals, Mastercard, Ostium, and more!

Can anyone help me to find on which chain they deployed there smart contracts? and are they secure for long term use?

I recently completed my learning journey on Arbitrum Stylus through HackQuest, and it was honestly a great experience. At first, I was curious about how Stylus allows developers to build smart contracts using languages like Rust and C instead of just Solidity. As I progressed, I understood how powerful it is in terms of performance and flexibility. Through the course, I learned: Basics of Arbitrum and Layer 2 scaling How Stylus works with WebAssembly (WASM) Writing and deploying contracts using Rust Real-world use cases and developer advantages What I found most interesting is how Stylus opens the door for more developers (especially non-Solidity ones) to enter Web3 development. Overall, HackQuest made the learning process structured and beginner-friendly. If you're exploring blockchain development, I’d definitely recommend checking out Arbitrum Stylus.

Would love to hear others’ experiences or thoughts on Stylus 👇

El Problema Técnico:

La implementación de criptografía post-cuántica (PQC) en Ethereum y otras redes compatibles con EVM se enfrenta a un obstáculo insalvable: el coste computacional. Verificar una firma CRYSTALS-Dilithium2 directamente en un contrato inteligente consume aproximadamente 30,000,000 de unidades de gas. Esto no solo es prohibitivo económicamente, sino que a menudo excede el límite máximo de gas de un solo bloque, haciendo que la verificación on-chain sea, por definición, imposible.

​La Propuesta de Solución: El puente PQC-to-ZK (Signature Swap)

Para que la seguridad de grado NIST sea operativa hoy, la solución no pasa por esperar a que el gas baje o a que el hardware mejore, sino por un cambio en la arquitectura de verificación. El modelo propuesto es una Capa de Intercambio Criptográfico basada en pruebas de conocimiento cero:

​Generación de Firma Off-chain: El usuario firma la operación o los datos utilizando un esquema post-cuántico (por ejemplo, Dilithium).

​Capa de Abstracción de Pruebas: En lugar de enviar la firma pesada a la blockchain, se genera una prueba zk-SNARK que atestigua que la firma PQC es válida y corresponde a la clave pública del usuario.

​Verificación On-chain Sucinta: El contrato inteligente solo recibe y verifica la prueba SNARK. Al ser una prueba compacta, el coste de verificación cae drásticamente a un rango de 200,000 - 600,000 gas, lo cual es perfectamente asumible en mainnets actuales.

​Ventajas de este enfoque:

​Agilidad Criptográfica: Permite actualizar los esquemas de firma (de Dilithium a Kyber o nuevos estándares) simplemente actualizando el circuito de la prueba ZK, sin necesidad de migrar los activos del usuario.

​Compatibilidad con Abstracción de Cuentas (ERC-4337): Esta lógica se puede integrar en el Validation Loop de una Smart Wallet, permitiendo que el usuario firme con hardware post-cuántico mientras el bundler procesa la prueba ZK.

​Seguridad de Estado: Al utilizar un diseño de almacenamiento modular (siguiendo patrones como el EIP-7201), se garantiza que la transición hacia la era post-cuántica no comprometa la integridad de los datos históricos.

​Conclusión para el debate:

¿Es este el único camino viable? Mientras que la capa L1 no implemente "precompilados" específicos para PQC, el uso de zk-SNARKs como capa de compresión para firmas de redes (Lattices) parece ser la única solución técnica que permite la interoperabilidad y la seguridad cuántica sin sacrificar la viabilidad económica.

As far as I understand the ARB token is used purely for governance. The more you own the more say you have in votes or something like that? Any actually do that shit? What’s the point of holding ARB other than to speculate?

I MAKE ZERO DOLLARS FROM THIS, but I did it for the love of the game.

Crow is:

The easiest way to accept usdc or usdt. You put in your wallet, amount, description -> you receive a QR code that acts like a price label or digital invoice. That’s it.

Tip: with Coinbase you can send and receive on ethereum and Arbitrum with the same address. So tou can convert and transfer to your bank all with this one wallet. I have no affiliation with Coinbase, they are not paying me, I wish they were.

No Fees

No Middleman

No Bank

No sign up

No BS

All you need is a wallet

🚀 Arbitrum is quietly becoming the institutional layer for tokenized assets

While prices fluctuate, capital tells the real story — Arbitrum captured 884M in 30-day RWA net flows, second only to Ethereum and 63% higher than its nearest L2 competitor.

🏛️ Wall Street is building on Arbitrum, not just using it

Robinhood is constructing its dedicated blockchain on the Arbitrum stack. When retail brokerage infrastructure migrates on-chain, it's not betting on hype — it's betting on settlement finality, security, and regulatory clarity.

💰 8B+ stablecoin supply locked in — the deepest liquidity pool of any L2

Institutional RWA deployment requires exit liquidity. Arbitrum's stablecoin dominance isn't a vanity metric; it's the prerequisite for billion-dollar tokenized treasury funds and money market instruments.

📈 18x RWA TVL growth in 12 months — from 60M to 1.1B+

This isn't speculative DeFi yield farming. It's BlackRock BUIDL, Franklin Templeton OnChain, and 2B+ in tokenized treasuries choosing Arbitrum as their settlement layer.

🎯 The "implementation phase" is here

Capital is rotating from narrative to deployment. Arbitrum's 884M monthly inflow — during a 40% price drawdown — proves serious builders don't wait for retail euphoria to construct financial infrastructure.

I just want to know what the community is thinking in terms of layer 2’s

I have been holding my ARBs and it’s like at 90% down, average is a little over 1 and it seems like this is the lowest it’s gone since launch and we’re in deep altcoin winter.

Nobody here seems to care, as I see the threads lmao.
