On EVM chains, an “unlimited approval” lets a contract move that token from your wallet whenever it likes. Fine for a contract you trust. A risk forever if that contract or its owner goes bad. Check: review and revoke old approvals regularly. #CryptoSecurity #DeFi
Fact: fake airdrop claim pages ask you to “connect and sign” to receive tokens. Read: receiving tokens doesn't need you to approve spending of your tokens. Check: if a claim asks for an approval or a signature you can't read, close the tab. #ScamAlert #Airdrops
Impostor accounts copy the name and avatar. They can't copy everything: > handle spelling (l vs I, extra underscores) > join date > who you know that follows them Check those three before you click anything in a reply. #ScamAlert #CryptoSecurity
Fact: real support teams don't open DMs to fix your problem. Read: a “support agent” who messages you after you post a complaint is the most common scam on X. Check: only contact support through the link on the official site. #CryptoSecurity #ScamAlert

We have just scheduled a preplanned parameter change, updating the StakerLpRewardCap (limit at which excess bankroll funds are paid out to stakers) to $10m, from $5m. This update will take place shortly after 18:45 UTC, Saturday 17th Oct.
Case file: the “$10M rug” story. > 10 Oct: Papertrade announced its staker reward cap would rise from $5M to $10M on 17 Oct. The pool keeps more before stakers get paid. > No report shows the team withdrawing user funds. > The real issue: PAPER can't be transferred. #Papertrade
Fact: no wallet, exchange or project needs your seed phrase to help you. Read: anyone who asks for it, in any words, is trying to take your funds. Check: if you've ever typed it into a website, move your funds to a new wallet today. #CryptoSecurity
Red flag, memecoin edition: GIGATENEV went ~17x yesterday after Robinhood CEO Vlad Tenev followed its X account. By the end of the day it was ~10x, roughly 40% off the top. When the whole catalyst is a follow, the exit risk is an unfollow.
Case file: 0x30af…393e on Hyperliquid Down ~$9.5M in a week (Hyperdash). Closed 1,355.6 BTC on Oct 18 for a ~$3.26M loss (Lookonchain). Same day: a ~$34.6M Tesla long at 20x. Liquidation ~$350.7. ~$2.8M equity, ~$46M exposure. Tesla reports after Wednesday's close.
Case file: Papertrade, 11 days in Oct 10: launch. 1000x perps against a pool, PAPER minted only from trader losses. Oct 18: a PAPER perp lists on Hyperliquid HIP-3. Oct 19: PAPER stays non-transferable. No timeline. PAPER has a price. Holders can't sell at it.
