Core dev building defi protection at @usd8_fi. smart contract auditor by day. Tweets are my own opinion.

this took a little while, but hopefully not too late for defi users.
Private beta officially open for usd8.fi, the first defi primitive offers free insurance. Perks on offer during private beta - x300 times insurance score rate for usd8 holders - 3 boosters Dm for an invitation if you haven't got one yet.

Ai will give rise to a new type of business, ones aren’t operatable by a single person, now it’s all possible. Businesses like - super low margin businesses - edge businesses operate in grey area - business with adversarial compatibility

if you are in defi and not covered, think again, seriously.

how to hack a defi protocol without consequences. 1. short the protocol token before the hack 2. hack the protocol, token price drops 3. exit short position, lock in profit 4. return hacked funds to the protocol and keep 10%

gonna love how cheap it is to deploy to Eth mainnet right now, 12 contracts cost $4.8.

The EIP's replay to ~block 25M found 2 post-Cancun SELFDESTRUCT burns, so dropping it breaks very little. A real burn primitive would still beat everyone sending ETH to 0xdead.
alright, i keep looking into the Glamsterdam EIPs. let's take EIP-8246: eips.ethereum.org/EIPS/eip-8…. we have more than 26,792 ETH sitting in major burn addresses. EIP-8246 wants to remove the remaining SELFDESTRUCT burn mechanics (see my quoted tweet, where i showcase the mechanics to be removed). and yes, it's correct that this mechanism is barely used in practice (unfortunately). but that's my challenge: is this not a failure on our part to make the possibility more prominent? i mean, i literally spoke to various smart contract devs today. _none_ (no joking) of them knew that you could _truly_ burn ETH at the protocol level. so, hmmmmm, instead of continuing to send eth to dead addresses, we should make "irreversible" burning more accessible if you ask me. even better, we should introduce a first-class burn primitive w/o requiring some fancy EVM magic. ulitmately, ETH sitting in dead addresses is effectively useless (unless i find their pk one day with my 24M-qubit machine lol), but it still exists in the protocol's state. irreversibly destroying ETH would actually remove it from the supply and makes it "cleaner".

this is terrible. could the boss find this tweet?
Pre-COVID, I managed to extort 28 BTC from my boss by putting ransomware on his PC. This ended up causing the company to collapse leading to everyone getting laid off without any suspects. I haven't heard anything back from him ever since. I am still holding the BTC to this day.

The nature of AI leads to centralised powers, blockchain is the force to balance that. This is how blockchain and AI gonna integrate.

working with @claudeai through different devices and with chat and code is just a nightmare... and Hermes does not have an ios app yet. the big opportunity - a harness cross platform, sync well and support voice chat.

Save crypto, don’t let it rot and die.
If you want to know why I’m so rattled recently, I’ve been in this space 10 years and it turned out not what I thought it was going to be. Crypto used to mean something, now it’s attracted the worst kind of people and I just can’t really relate to any of it. Imagine being in a club that played absolutely amazing tech house bangers, you’re having the time of your life and then someone comes along and starts playing gay disco, the doors are locked, you can’t get out.

Unless we build enforcement layer for crypto, terrible things like this will happen more often. Crypto could becomes a dystopia and die, it is already well on its way.
THE BLOCK: Crypto trader "realist" was allegedly robbed of roughly $800,000 in crypto during a home invasion in the UK. According to his posts on X, intruders used tape, held knives to his face, and forced the transfer of funds held in his wallets and a Ledger device. The trader said he only sustained a few bruises.

Low risk defi is a critical primitive now with security threats everywhere.
Free Defi Insurance, coming soon.

this is so true.
you're gonna read this. some of you aren't gonna like it. and that's probably who needs to read it the most. crypto twitter right now is mostly people flexing how much money they made and whatever salacious bullshit gets the most engagement that week. you got the same extraction schemes, netflix recycling the sbf fraud story, and influencers with the most punchable faces in crypto telling everybody how much money they make while the rest of the timeline fights over who’s the bigger asshole. real rich people don’t flex like that. they never did. these young guys don’t know what the fuck they’re talking about half the time. they’re just loud. and apparently that’s all it takes now. meanwhile, the people actually making art, building things, and doing something interesting are still here. they just don’t get the same attention because they’re not turning every fucking post into a fight or a screenshot of their bank account. nobody came here for this version of crypto. and a lot of you are doing more damage to this space than you probably realize. i’ve been around since 2020. i’ve made money, lost money, made friends, had fun, and had fun with some of you. and here’s something you figure out when you get to 40 or 50. you look at people half your age and realize just how much you didn’t know when you were that young. a lot of you are lovely people. genuinely. but some of you don’t know what the fuck you’re talking about, and the worst part is you’ve convinced yourselves that you do. you’re having fun. great. i had fun. i still have fun. but somewhere along the way, a bunch of people confused getting rich with being smart and getting attention with being respected. they’re not the same fucking thing. and some of you are becoming a laughing stock. you really are. not because you’re young. not because you’re making money. because you’ve made being an obnoxious asshole your entire personality and somehow convinced yourselves that’s success. the saddest part is there are still people here doing incredible things. making art, building something, actually giving a shit about what this space could be. there was something pretty special here. and i think it’s still in there somewhere. but if the clowns would shut the fuck up for five minutes, maybe the rest of us could actually hear it. and see it. because right now the circus is louder than the people building the fucking tent.

This is so sad. Get protection if you are onchain, its free from us.
someone who lost $3m just sent this message to the hacker... always remember about safety in crypto, never share your seed phrase with anyone and don't click links you don't trust

the new @papertrade_xyz model is very powerful imo. Its basically a leveraged trading platform, but losses can be converted to robinhood:0xaa3b129e4906009e228a060340601260de068ff5 which can be staked to share protocol revenue. Interesting model. Would love to see more of these applies to non speculative / gambling projects tho.

terrible!
I hate this so much. The top Google result (an ad) leads to a well-made scam version of @safe. Given how often legitimate crypto projects get suspended from ad programs, fkn @Google still happily sells its top spot to scammers after all these years.

a revoked key still works until its old root expires in ERC-8403's cheap tier. the current-storage tier rejects it from the next block. i'd pick that for a wallet; 'revoke' shouldn't need a countdown. still a draft, not a shipped Ethereum change.
New post on Eth Research! ERC-8403: an account as one hash, and post-quantum keys By: - AnkushinDaniil 🔗 ethresear.ch/t/26147 Highlights: - ERC-8403 proposes a standard “authority lifecycle” for native account abstraction by representing all account authorities (keys or other predicates like limits/time locks) as Merkle-tree leaves and storing only a single 32-byte root in the account. - Transactions must include both a membership proof (the authority leaf is under the stored root) and a witness (e.g., a signature) so that public knowledge of the leaf set doesn’t let others impersonate the sender. - Key add/rotate/revoke are unified into one action: update the root; the account address stays unchanged, but revocation speed depends on whether the account reads a recent named root (tier 1, cheaper but revokes lag) or reads current storage (tier 2, faster revoke but not in the cheap path). - For multi-chain use, the root is anchored on a “home chain”; other chains can verify the root via a storage proof against an imported home-chain state root, avoiding copying key sets across chains (revocations propagate as the home root updates). - Post-quantum integration: ERC-8403 is signature-scheme-agnostic, so PQ keys can be leaves; combined with EIP-8288, PQ signatures can be validated via per-block aggregated STARKs, and an optional approach can move both “signature validity + membership under root” into a single proof at the cost of larger mempool payloads and upgrade/standardization challenges. ELI5: Imagine your Ethereum account has a single “fingerprint” (a hash) that represents a list of allowed ways to approve spending (keys, limits, time locks). Each allowed rule is like a card in a box, and the account only stores the box’s seal (a Merkle root). To use a rule, you show (1) a receipt proving your card is in the sealed box (a Merkle proof) and (2) evidence you control that card (like a signature). Changing keys (add/rotate/revoke) just means resealing the box with a new fingerprint, while keeping the same account address. This can also work with post-quantum keys by treating them as just another kind of “card,” especially alongside EIP-8288 which makes big post-quantum signatures cheaper by proving them in aggregated proofs instead of on-chain.
