-
- The overall crypto market has lost ~2T from its mcap since november.
- Played with OUs and IAM in AWS.
- Formalized all geth documentation.
-
- Unit. Banking as a service.
- https://www.unit.co/
- For developers to integrate financial services into their apps. Cards, payments, banking info, etc.
- They own compliance/regulation.
- DFNS. Custody as a service.
- https://www.dfns.co/
- APIs to generate wallets, sign transactions, key management, etc.
- They own compliance.
- Can specify policies as well.
- Set up macbook keyboard shortcuts for ctrl-option-<arrow> to tile windows left and right.
- On mac, fn-del is for forward delete, since there’s no separate key.
- Option-arrow is for jumping words. Command-arrow is for home/end (although fn-arrow works as well).
- UST/LUNA.
- When a user wants to swap LUNA for UST, guaranteed 1:1 in quantity (not value), a portion of LUNA is burned and a portion goes into the treasury.
- The burning of LUNA reduces LUNA’s supply, increasing its price.
- The minting of UST increases its supply, decreasing its price.
- This is how UST goes back down to $1 if it’s over $1. Users are incentivized to.
- The exact opposite is also true. If UST is below $1, users will trade 1 USDC for 1 LUNA, make a profit, and the value of USDC will increase by burning USDC and the value of LUNA will decrease by mingting LUNA.
- Arbitrage in both directions – this is what stabilizes UST.
- The treasury then buys bitcoin (or other non-terra-ecosystem value-holders) to further diversity and increase confidence.
- Matt Levine with a great quote: “(1) Ponzi, (2) acceptance, (3) diversification, (4) permanence.” Fake it till you make it, baby.
- LFG = Luna Foundation Guard.
- Connecting vscode to EC2 instance.
- Just use the “remote – ssh” extension.
- Get the pem of the keypair that launched the instance in a local file (chmod 400), the username, and the amazon-provided hostname, then add all that to a Host entry in ~/.ssh/config.
- Then simply add the host in vscode (it knows to check that file) then connect to that host.
- Easy. All through ssh conf.
- StakeDAO: https://stakedao.org/
- Full eth network, private, aws. Click PoA, bootnode, puppeth for genesis, clef for key management. Done.

- UST lost a bit of its peg, as low as <70c.
- Google cloud is starting a web3 internal team.
- Desktop access.

- Generated a key, added. Still couldn’t access. Gave up. Think I’m still blocked by Win11 Home edition; no rdp, maybe no remote tcp as well.
- Remember my fios router has DNS as well, of course.
- Learn+Earn Platforms. Coinmarketcap has one. It’s currently running a BNB series. Basically: watch videos to learn about various BNB protocols, take quizzes, earn BNB coin. https://coinmarketcap.com/earn/project/how-to-web3-on-bnb-chain
- Shopify is an ecommerce platform.
- They provide the payment services, the shipping services, the website building services, etc. Go to them if you have a site and product you want to launch.
- They offer APIs, much more.
- There are many third-party extensions, or shopify apps, that can augment your online store. Could be analytics, SEO boosters, coupon programs, recommendation engines, etc. Anything a merchant might need. A plugin marketplace for online businesses built on shopify.
- Shopify controls the data flowing through all these apps. They control the api, security, permissions, etc.
- These plugins usually have a subscription model. Shopify itself has a few revenue streams, the primary being transaction fees?
- Their mcap is 45B.
-
- Eth private network. Understood geth very deeply. Clef/bootnode/2miners/cliquePoA.
- Updated my aptos devnet node to chain_id 13.
-
- Yuga Labs (BAYC) had the Otherside release on saturday.
- Metaverse game. People bought plots of land. They’re NFTs called Otherdeeds.
- 55k available.
- They raised $320M.
- Even disrupted the eth network for a bit. Gas skyrocketed.
- They were purchased with ApeCoin, for about $5800 apiece.
- The composite rate for I bonds issued from May 2022 through October 2022 is 9.62 percent. https://www.treasurydirect.gov/indiv/research/indepth/ibonds/res_ibonds_iratesandterms.htm.
- Positioned tsla, btc, amt reit, eqix reit.
- Zoom doesn’t allow “Call Me” by default, only computer audio and “Call In”. The host has to enable the “Call Me” addon.
- Solana transaction submission is weird, since no mempool? You basically spam the leader. This causes problems, like yesterday’s mainnet outage.
- Banks actually lend to each other every day. They move liquidity around. There’s a nightly balance minimum that is enforced on each bank, so they share. When the fed raises interest, they just increase the rate for bank-to-bank lending. Which then cascades through everything else, like mortgages, asset-backed loans, savings accounts, CDs, etc.
-
- Aptos.
- Updated devnet fullnode to chainid 11 (so this is the 11th devnet weekly cycle?).
- Better node info site: https://aptos-node.info/
- Didn’t have to cycle keys. Did run docker system prune -af though, was getting an error on startup.
- Strike is a bitcoin payment mobile app. https://strike.me/en/. A wallet, can onboard fiat, shows btc price, can send/receive money easily. You create an account with them. They have cards too for offboarding. Only bitcoin.
- Figure (crypto mortgage lender).
- Remember flipside crypo. Basically a bounty AND freelance program. “Create a visualization of this analytic on this token on this chain etc”.
- Plaid; remember it’s the same way to connect your accounts to apps. Helpful for fintech. Plaid is what Intuit used to connect my TurboTax to my Bank of Amercia, for example.
- Tornado.
- Supports eth and all L2s. And BSC and avalanche.
- Deposit from one address. They give you a private key. Then withdraw from another address. The private key gives you access to that fund. No one else can link the deposit to the withdrawal, only the holder of the private key.
- Tornado Cash was the original app. Nova is the second-gen app.
- Rest APIs to query blockchain data already exist. Kaleido, Block Cypher, more. The Graph (https://thegraph.com/en/) is another big one.
- Spectral.
- Web3 credit score.
- MACRO = Multi Asset Credit Risk Oracle.
- You can compose your score based on transactional history across many addresses.
- You get an ERC721 NFT which identifies your score. All the inputs are only based on ethereum too. I assume later will be crosschain. You then use this score on Spectral’s liquidity pools (they offer direct lending as well, a critical piece; unless others start adopting the NFT everywhere).
- The NFT has the owner data directly in its json; you can’t just send it to someone else.
- Joined the discord, subscribed to medium.
- They haven’t launched yet. App isn’t available. They’ve delayed a few times, but looks like the open beta will begin in about a month (May 2022).
- The inputs (right now):
- Transaction history. Who you have interacted with, how much.
- Rug pull history. Have you interacted with any smart contracts that have been flagged as rugs?
- If you’ve been liquidated ever in a lending protocol. This is the web2-credit-equivalent of defaulting, or more minorly: not making a payment on time.
- Lending protocol repayment. How much you’ve borrowed, how much you’ve repaid.
- How much overall defi interaction you’ve had. The more experience is assumed, the higher score.
- Total timeline/history. Longer better.Range is still 300-850.
- The scoring model / weights / etc is still in flux. Mostly AI-driven.
- The credit score doesn’t just have to apply to loans. Can be a factor in many other things: yield rates, social media banners, login, access, any part of your DID (decentralized identity, web3 identity).
-
- Mortgage/lending.
- https://www.figure.com/
- Crypto-backed loans have APRs from 6-8%. Can get up to a million (with how much collateral, what LTV?), and no need for credit check.
- Home loans come in many options up to 30yr fixed. Can get in as few as 5 days. Can get up to 400k.
- Personal loans can land in ~1 day, up to 50k.
- Rift.
- https://rift.finance/.
- Primary doc: https://docs.rift.finance/protocol-overview/how-it-works.
- DAOs deposit their tokens into Rift vaults. Liquidity providers deposit eth into those vaults. These are matched and added to DEXes. The liquidity providers get 100% of the rewards, while only provided 50% of the liquidity (so they get 2x what they would have gotten if they’d gone straight to a DEX and provided liquidity). DAOs get twice the liquidity. They can withdraw at any time.
- Gem is an NFT marketplace aggregator. Opensea just bought it.
- Remember tornado for private eth transactions: https://tornado.cash/.
- Alice: one stop shop for all personal finance needs.
- Class action against uniswap: https://www.theblockcrypto.com/news+/143661/a-class-action-lawsuit-against-uniswap-spotlights-gaps-in-defi-regulation. Basically says that if they had registered with the SEC and had more regulation, users would be better protected against fraudulent activity.
- TSLA dropped 12% from the elon twitter news of deal closure, and twitter fell as well. Google missed earnings (youtube lost a lot of attention to tiktok). MSFT beat. Robinhood laying off 9% of its workforce.
- Remember by default, yarn will install your dev deps. Need to add –prod or NODE_ENV=production or the other variants to exclude dev deps.
- Moonpay isn’t the only company for fiat onboarding, obviously. I’ve used Transak before.
- Recent hacks and categorization.
- Ronin. A custom/expert. Found a design flaw that wasn’t reverted, got a validator.
- Scams. User phishing. Discord. NFTs. “send your keys for help”
- Rugs. General.
- Bridge. Wormhole.
- Governance attacks. Beanstalk. Flash loan.
- Market manipulation. Driving oracles. This happened with cream.finance.
- Qubit. Unlimited minting.
