Una persona que conozco quiere que abra una cuenta electrónica tipo tarjeta visa. Dice que es para cosas de criptos. ¿que no me pasaría nada a mi cuenta bancaria y tarjeta física del banco?.

Mi duda es, si hay riesgos que sea una estafa y si quiera robarme algo a mi o como funciona realmente.

Qué cosas debería evitar por aquello que sea una estafa a mi cuenta bancaria, que no es la electrónica

the snapshot problem in restaking governance

i keep coming back to a gap in the OZ Governor pattern when the underlying is a restaking position. ERC20Votes snapshots voting weight at proposal-creation block, which works fine for plain governance tokens. But between snapshot and execution the token can get slashed by an AVS, re-staked into a different operator set, or re-delegated. The recorded balance no longer matches the real economic stake by the time the call lands.

The standard answer is snapshot-and-shrug. Let slashed stake keep its vote, treat the drift as a known anti-feature. the alternative is to re-evaluate at execution against current stake, but then results can flip after voters have signed off, which kills predictability.

every restaking-era governor i've looked at picks option one. so the honest position is that restaking and token-vote governance aren't compatible at the precision people pretend, and the gap shows up at execution time.

The Ethereum Foundation security discussions this week made me rethink my wallet setup

Been thinking a lot about the Ethereum Foundation security conversations this week and I realized my whole mental model around wallet safety was still kinda outdated.

I always thought good security mostly meant keeping keys offline, backing up the seed phrase properly and avoiding obvious phishing attempts. But now it feels like transaction interpretation itself is becoming just as important.

Most people aren’t losing funds because cryptography failed. They’re losing funds because they approved something they didn’t fully understand while interacting with increasingly complicated protocols.

Makes me wonder if blind signing eventually becomes viewed as completely unacceptable UX in crypto.

meet the hardware wallet that looks like a game boy and possesses the ethos of a seasoned self-sovereign vet

the keycard shell understood the assignment.

because it's not about the looks, the cool factor, or some other shallow thing other hardware wallets might advertise.

it's about the mission.

and there's no other hardware wallet as true-to-ethos (sic cypherpunk) and self-sovereign as the Keycard Shell.

it combines the best of:

  • NFC chip card form factor for tapping on-the-go while securing your private keys
  • QR code based signing (when card is inserted into the Shell) for FULLY AIRGAPPED security
  • using an S-tier battery design choice (it uses nokia BL-4C batteries aka brick phone batteries that can be swapped out in seconds and purchased freely on the open market)
  • being radically open source (it's so open, you can literally manufacture your own 😂)

honestly, it's not much to look at. it's a cross between a retro game boy and a 90s calculator. 

but the see-through body is akin to a beautiful metaphor for the Keycard Shell — the premise of its security model is that it sits out in the open with nothing to hide.

what's r/ethereum's thoughts? can you get behind this clunker aesthetically for its mission-driven design?

Cheapest DEX for swapping above $10k?

Hey! I need some help...

I swapped $22k of ETH to USDC on Uniswap last week and lost $480 to slippage alone. Never had this problem with smaller amounts but anything above $10k and the price impact gets ugly fast.

Is there something better for larger swaps or am I missing a setting somewhere?

I lost money this week and it wasn't even a scam

I lost money twice in the same week, it wasn't a rug or a hack. I lost to my own wallet.

First time — I was managing like six addresses across three chains, I could literally feel my adrenaline 😭. A new L1 just dropped and the chart was going crazy. So I copy an address, I send and I was waiting for conformation on the other chain but unfortunately after checking again it was the wrong one. And my funds where gone just like that. The wallet didn't flinch. No warning. Just a little confirmation tick like it was proud of itself. It was my fault, I know but sending money shouldn't require me to have a cs degree, understanding chains and stuff. Crypto wasn't correctly built for humans, I'm sure you agree with me 😭.

Second time — same week, same opportunity. My friend is newer to this. He had funds sitting across four different chains but couldn't move fast enough because half of it was stuck, wrong network, not enough gas on another, bridge taking 20 minutes. By the time we figured it out, the window was closed. He had the money, he just couldn't use it.

We both got wrecked by the tooling instead of the market 😂.

I've been quietly thinking about what a wallet looks like if it was actually built for humans. Like what if the chain was just nobody's problem but the app's. You own your keys, you move your money, and the complexity just... disappears underneath. Wild concept, I know.

Just curious, what's the most unhinged thing a wallet has made you do just to complete a basic transaction?

Ask me what I'm building if you're curious 👽

I built a stablecoin technical reference - contract addresses, EIP/ERC matrix deep dives and compliance & wallet blacklist checker

Hi everyone, I got tired of trawling through docs and block explorers every time I needed a stablecoin contract address or wanted to check which tokens support permit signatures, so I built a reference site!

I wanted to introduce stablemoney.dev

Covering:

  • 12 major stablecoins (USDT, USDC, DAI, PYUSD, GHO, RLUSD, etc.)
  • Contract addresses for every major EVM chain
  • EIP/ERC compliance matrix (ERC-20, permit, proxies, compliance hooks, flash loans etc)
  • On-chain wallet compliance checker (read-only eth_call - checks onchain blacklist/freeze status)
  • Opinionated risk notes per coin
  • Basic Market cap from DefiLlama, refreshed daily

OpenSource, no wallet connection needed, MIT licensed.

Would love feedback from anyone building with stablecoins. What’s missing that would save you time?

Uniswap alternative for large swaps?

Hi everyone, been using Uniswap for a while now but every time I try to swap anything above $10k the price impact just kills me. Did a $14k ETH to USDC swap last week and lost around $300 to slippage alone which seems way too much for such a common pair.

Is there a better option for larger amounts or is there something I should be setting differently? Any advice appreciated!

Cheapest way to convert stETH to ETH?

I had no idea the Lido withdrawal process was this painful. Submitted my unstake request and got some NFT back, then waited 18 days just to manually claim my ETH. Missed the whole reason I needed it in the first place.
Is there a faster way to get ETH out of a stETH position or is this just how it works? Feels like there has to be something I'm missing. Thanks

Polymarket scam

There's a lot of news today about how users lost money on Polymarket

In the Russia-Ukraine ceasefire market, they suddenly counted the May 9 humanitarian pause as an official ceasefire 🤯

People around the world are already pointing out the double standards and accusing the platform of bad faith.

Polymarket clearly scammed its players.

Build projects or learn Uniswap v4 ??

Heyy Guys, im back from learning foundry and next looking to build some projects and host them in the testnet.

I was thinking of building a standard and solid project (like DAO/DEX) instead of small projects..

So when i looked up, i came to know that uniswap is very useful in developing commercial level projects and has many built-in features ideal for production grade apps..

Now should i learn Uniswap and then build a solid project or just build a project and then learn Uniswap..

Thanks in advance...

How do you get yields/interests on USDC?

I hold Bitcoin and Ethereum and USDC on the side that aren't moving/being used at all, I'd like to "stake" some of it in order to get extra %/free money. I've started digging how to do it safely (without involving a CEX) but every guide either points to coinbase/kraken... Is there a non-custodial way to Stake USDC?

What are you guys using for it?

The RPC bottleneck of ethgetLogs: EVM event architecture and topic filtering

EVM events don't live in state; they sit in the transaction receipt logs. When you fire an ethgetLogs RPC call, you are leveraging the node's bloom filters to query these receipts without touching the state trie.

The architectural constraint here is the topic limit. An event can have up to 4 topics: topics0 is the keccak256 signature hash (e.g., keccak256("Transfer(address,address,uint256)")), leaving only 3 slots for indexed parameters. These are fixed at 32 bytes. Node providers can rapidly filter these topics because they function as native search keys.

Everything else is packed into the unindexed data blob as raw bytes. The trade-off:
keeping fields unindexed saves EVM gas by avoiding topic structuring, but pushes the computational load to your off-chain infra, which now has to pull the raw logs and ABI-decode the hex blobs manually. When you construct an RPC call searching for a specific block range and target address, minimizing the reliance on unindexed data decoding is crucial for high-throughput indexers.

I asked Vitalik on X if this goes off, ETH chain will have primetime again and

Asteroid OG will be the runner this bullrun.

The Cabal will fud this, i know they are pounding heavy money on their chart, if you look onchain, every pump is fake and the distribution is insane diluted (whales bundled it big time). Their pumps are insane faked by BIG whales, the market is looking at them like they are the one and they have the biggest cap.

we all know,
we all have seen this,
we are David vs Goliath,
this can be the gamestop of 2026.

We just need some friendly whales who understand and see this thesis.

The one and only Asteroid by Vitalik:

$770 million stolen in defi this year. 40+ protocols shut down. bridges are the common denominator and nobody is fixing the actual problem.

the numbers from 2026 so far are genuinely scary:

  • kelp DAO: $293M drained through their layerzero bridge. single exploit hit 20+ chains because one bridge contract held the reserves for all of them
  • drift protocol: $285M. north korean hackers spent 6 months social engineering their way in
  • 1inch/trustedvolumes: $6.7M last week. same attacker from the 2025 hack came back and found a new door
  • april 2026 alone: $600M+ stolen across 28-30 separate incidents. worst single month in crypto history

40+ protocols have shut down or entered wind-down mode this year. aave froze rsETH markets and lost $6 billion in TVL from panic withdrawals even though their contracts weren't touched.

the pattern isn't random. bridges keep producing the biggest single-day losses because they're designed as massive honeypots. $22 billion in bridge TVL as of march, each one a single point of failure for every protocol downstream.

what bugs me is the response is always the same. "we need better audits." "we need better monitoring." nobody is questioning whether the bridge model itself is fundamentally broken.

bridges work by locking assets on one chain and minting representations on another through a trusted intermediary (multisig, oracle network, validator set). every one of these is an attack surface. kelp's bridge got spoofed because layerzero's messaging layer was fooled into thinking the withdrawal was legitimate.

the alternative exists. data availability layers can handle cross-chain verification without lock-and-mint. instead of one contract holding $293M that can be drained in a single tx, you verify data availability cryptographically across chains. no honeypot, no single point of failure, no trusted intermediary to spoof.

DA layers like avail, celestia, eigenda are live and production ready. the tech isn't theoretical anymore. it's an adoption problem not a research problem.

at what point do we stop patching bridges and start replacing them?
