What if blockchain could bring real value back to photography?

Hey Arbitrum community!

We'd love to introduce Pola, a live iPhone photography platform that wouldn't have become a reality in its current form without Arbitrum One.

But our story didn't begin with blockchain. It began with an iconic invention from the past: the original analog Polaroid instant camera. 📸

One photograph. One moment. One original.

The magic of classic Polaroid photography was that every shot produced a single physical original. No endless digital copies. No infinite editing.

We wanted to bring that philosophy into the digital age.

In a world increasingly flooded with AI-generated images, advertising, and engagement-driven algorithms, we wanted to build something different.

That's how Pola was born.

An ad-free photography community where every image is captured directly through a camera. No uploading from the camera roll. No automatic saving of captured photos to the phone's photo library. No AI image generation or AI editing tools.

And with Pola Pro, photographers can even use CCAPI-compatible Canon cameras.

But how do you give a photograph a verifiable digital original?

That's where Arbitrum One enters the story. 🔷

Every photograph published on Pola becomes a unique 1/1 NFT, authenticated on Arbitrum One, with IPFS-based image storage.

The goal isn't to make digital image data impossible to copy. It's to establish one verifiable original with clearly defined ownership.

Why Arbitrum?

Because making Pola economically viable required three things: fast transactions, reliable blockchain infrastructure, and extremely low network fees.

We didn't want blockchain authentication to be a luxury reserved for wealthy NFT collectors. We wanted it to be accessible to everyday photographers.

High gas fees would have made that vision economically impossible.

Arbitrum One's speed and low transaction costs made it possible for Pola to charge a service fee of just $0.50 worth of ETH per published photograph, plus the variable, low Arbitrum network gas fee.

And this is about much more than technology.

It's what makes our ad-free business model possible.

We don't need to flood the platform with advertising. We don't need engagement-manipulating algorithms designed to keep people scrolling endlessly. Our service fees help support the platform, while our closed camera-based capture system is designed around authentic photography.

🔐 YOUR WALLET. YOUR DECISION.

We integrated MetaMask directly into Pola. Users review and approve blockchain transactions within their own MetaMask wallets, keeping control of transaction confirmations in their own hands.

But there's something else we wanted to change.

On traditional social media, a photograph often earns nothing more than a few hearts or likes.

Why should that be the only value a creator gets from their work?

🎨 CREATE. COLLECT. EARN.

On Pola, photographers can offer their unique digital originals for sale, while others can buy and collect them.

On every successful sale, the seller receives 95% of the sale price. Pola charges just a 5% marketplace fee. Any applicable blockchain transaction costs are additional.

Photography can become more than content to scroll past. It can become a verifiable digital original with real ownership and the opportunity to earn from creative work.

Pola is already live on the App Store. 🚀

REALITY DOESN'T NEED A PROMPT.

Finally, a huge thank you to the r/Arbitrum moderators for allowing us to share our project, and to the Arbitrum community for giving us the opportunity to introduce what we've built!

We'd genuinely love to hear your thoughts.

What other possibilities do you think Arbitrum could unlock for creators?

For us, one thing is certain:

Without Arbitrum One, Pola wouldn't exist in the form we've built it today.

Thank you, Arbitrum! ❤️🔷

What is the best platform to move ETH from Optimism to Arbitrum in terms of security and cost?

Also, do ETH on Optimism turn into ETH on Arbitrum or some other token (weth, eth.arb, I don't know...)?

RWAs only get interesting to me when they can actually be used, not just held. On Arbitrum that could mean lending, borrowing, or using tokenized Treasuries and metals as collateral.

Would plugging them into DeFi make them genuinely useful, or just add smart contract and liquidity risk on top of the asset itself?

Hi All,

I'm looking for bear metal RPC providers based out of India. Building a major cross-chain intent protocol + ZK proving.

Cheers

The price move is obvious, but I’m more curious about the actual value capture. Robinhood Chain adds activity and revenue to the Arbitrum ecosystem, but that doesn’t mean ARB holders directly receive that revenue. So how are you guys thinking about this? Is it a real improvement to the ARB thesis, or mostly a strong ecosystem narrative with indirect token impact?

Been holding for a very long time. Sold at the bottom. Original plan was let it go to zero. It’s like as soon as I sold it decided to pump. Everyday I’m reminded of its positive trajectory. One is a fool.

Any reason in particular for the recent pump?

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.

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?

Link: glacient (.) ai (no signup needed to preview a wallet)

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!

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.

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?

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?

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 👇
