MOONS Arbitrum to minimize Arbitrum Nova - Moons need to bridged

8 Upvotes

If you're holding MOON on Arbitrum Nova, this affects you.

What happened

The Arbitrum DAO passed a proposal to "minimize" Arbitrum Nova. That means Nova isn't being shut down, but it's being moved into a maintenance-only state with reduced infrastructure, slower support, and stricter rate limits. Data availability shifts to Ethereum L1 blobs, and most service-provider contracts get deprecated.

The short version: the chain keeps existing, but you should not plan to keep anything important on it.

The timeline

  • June 4 – September 2, 2026: 90-day migration window. Everything stays fully operational. This is when you move your tokens.
  • After September 2: Nova drops to a minimized state. Bridging is still possible, but with less support and potentially fewer fast-bridge options available.

You can technically still migrate after the deadline (the Arbitrum Canonical Bridge stays accessible through the Arbitrum Portal), but you'll have fewer tools and slower help. Don't wait.

How to migrate your MOON

There is no direct path to move MOON from Nova to Arbitrum One through the official Arbitrum Portal. You have two routes:

Option A: Canonical route (via Ethereum)

  1. Move MOON from Arbitrum Nova to Ethereum via the Arbitrum Portal.
  2. Wait through the ~7-day challenge/confirmation period, then claim the token on Ethereum.
  3. Bridge MOON from Ethereum to Arbitrum One via the Arbitrum Portal.

This is the slower route, but it doesn't depend on third-party liquidity.

Option B: MoonBridge (direct Nova → One)

moonbridge[.]cc bridges MOON directly between Arbitrum Nova and Arbitrum One (it also supports Ethereum and Gnosis). It's a 1:1 token bridge that I made for the CCMOON DAo, not a swap, so there's no price impact or slippage on your MOON.

The one thing to watch is destination liquidity. If your transfer is larger than the available liquidity on the destination side, the portion that can't be filled is refunded (the fee on refunds is 1%, same as the 1% fee on fulfilled amounts, plus a relayer fee). For larger holdings, check the destination liquidity shown in the interface and split into smaller transfers if needed.

Bottom line

Move your MOON during the June 4 – September 2 window while everything still works smoothly. MoonBridge gives you a direct Nova → One path if liquidity covers your size; the canonical route through Ethereum always works but takes 7+ days. The Arbitrum Canonical Bridge will keep working after the window closes, but support and bridging options get thinner once Phase 3 kicks in.

ADVICE What happens to your crypto when you die? 2026 Guide to crypto inheritance

8 Upvotes

Interesting read. Gives you something real to think about.
4 million BTC ($40B) already lost forever. Your crypto might be next - and most people still have zero plan.

  1. No major exchange (Coinbase, Binance, Kraken) lets you name a beneficiary. Your heirs will have to go through probate court and then customer support while the market does whatever it wants.
  2. You don’t inherit the coins - you inherit the private key. If your family can’t reconstruct it, the crypto stays visible on the blockchain forever but completely unspendable.
  3. The good news: you can fix this today. Make a simple inventory (no keys), write a plain-language letter of instruction, never put the seed in your will, and for serious money use Shamir shares or a time-delayed multisig (Casa / Nunchuk / Unchained).

DISCUSSION Invested 5000$ properly for the first time

11 Upvotes

I've been in the cryptosphere since 2018 but I never put serious money or hold it properly for long term. All I did was occasionally trading meme coin with $100 or $200 but nothing above $400. With the rising usage of AI and my job being at risk (Software Engineer) I feel like now is the perfect time to buy and hodl for the future because the future doesn't look very good with AI around. Now that I have a proper job and proper saving, I have decided to buy a cold wallet and put some of my life saving into cryptocurrency and keep it in my safe and DCA from this time onward. Here's what I invested:

- $3000 on Bitcoin

- $1000 in Ethereum

- $1000 in Solana

The most trust I have between these 3 is Bitcoin because it seems to be the one who's doing well the most in term of long time period. Excited to join the hodl family and cheer!

🛡️ SECURITY a MiCA-licensed, fully authorized stablecoin issuer just got hacked through the exact thing licensing was supposed to prevent

9 Upvotes

Proof that the regulated perimeter does not equal the secure perimeter. been seeing a lot of "just wait until everything's regulated, then it'll be safe" takes in defi/stablecoin threads lately, so this felt worth sharing.

hacken released its q2 security and compliance report, and in this era of regulation boom, this case is worth sharing.

so, stablr (usdr/eurr) is mica-authorized lost $2.8M this quarter because one of its three mint keys got compromised

what makes this specific case interesting is that key/mint-authority management is exactly the kind of operational control mica's underlying framework (dora) is supposed to require issuers to have locked down. it's not a gap in the rules on paper. it's that authorization checks whether you have a security policy document and pass a point-in-time pentest, not whether your actual key management setup survives a real attempt. the loss happened inside the regulated perimeter, after full authorization, not from some unlicensed fly-by-night issuer.

not saying mica is pointless, but "licensed" not always mean "operationally secure"

ADVICE Twice in 2026, months apart, I copied a cryptocurrency deposit address from an exchange and the transaction went to the same unrelated EVM address -- clearly I have some malware or something, or maybe something less malicious -- anyone have any advice?

3 Upvotes

Incident 1: I copied a Gemini BNB Smart Chain deposit address and withdrew BNB from Kraken. Gemini later confirmed that the destination was not associated with Gemini. This was done on a Firefox browser through Gemini and Kraken's website.

Incident 2: Six months later I copied a Kraken USDC/Arbitrum One deposit address and sent from MetaMask. It again went to the exact same unrelated address. This was done through an Opera browser via MetaMask extension.

Both were performed on the same Windows computer, using different browsers. The first incident did not involve MetaMask. I have successfully copied many other crypto addresses without this happening.

Has anyone encountered malware or a clipboard utility that selectively replaces only EVM addresses or triggers only inside crypto transaction forms? What diagnostic tools and persistence locations should I inspect?

DISCUSSION Question about p2p trades

Upvotes

When selling crypto on a p2p platform, what’s to stop me from receiving their payment and then not releasing the crypto ?

I’d never do this of course, just really curious, but I recently got into crypto trading and I noticed what seems like a glaring issue. When I sell crypto, I receive the persons payment before I’ve released the crypto. Whats to stop me from taking the payment and just never releasing the crypto? I know escrow is involved where the crypto is kept or something but I’m not really sure how that works. What if I just tell the crypto platform I never received the payment and they release my crypto back to me?

Again, would never do this, just very curious.

EXCHANGES help me withdraw please

0 Upvotes

Hi everyone,

Does anyone know of a good way to withdraw my money? I have USDT, but I have no idea how to cash it out. I live in Spain, and my funds are basically stuck because I don't really understand how any of this works.

I'm a freelancer, and one of my clients occasionally pays me in USDT, so I'm just looking for the easiest way to convert it into euros and withdraw it to my bank account.

ADVICE Good apps for stable coins investments, besides other cryptocurrencies, where I can get a decent APY and runs on Europe with MiCA license?

1 Upvotes

I've been on an app called white bit and what I can say is that I can easily call it the best one for trading and investments with I think the highest APY I've seen so far esp. for stable coins.

Now that they separate it into two versions ( one just for Europeans ) I have to send my money somewhere else, though I have no idea which service to use.

I'm doing both investments and trading so if you guys have some advice for some services that has somewhat low fees for trading and good APY, I'll be grateful.

Thanks.

It all seems such a long time ago. I see the cheapest are only (?!?!) £20K these days. I know a few years ago I was looking around a discount store and there was a box of Bored Ape keyrings. I got one for £3 as a souvenir. I can guarantee that nobody who shopped there knew what they were. Does Twitter still support them?

DISCUSSION DEXE rug pull?

18 Upvotes

I noticed this coin pop up on the market cap ranking about two weeks ago and was sitting at about the 21st spot out of nowhere. I was watching it for about a week and a half or so and this morning noticed that it behaved like it got rugged free falling from $49 to currently six dollars.

I’m wondering if anyone knows precisely what happened or if it was in fact rug pulled because during my looking into it, I noticed that the white paper and GitHub hasn’t been touched in many years, but was also net with resistance when I asked about the project originally.

Was anyone in the coin? Any idea what’s going on?

I’m kind of upset I didn’t short it and even at this point I’m questioning if it’s a bad idea to jump in now
