Native Android SDKs for EVM?
In the meantime, one thing that might be helpful for Android developers is updating the document and/or providing the workaround. If an Android developer follows the documentation, an app won't work. A note along the lines of "web3j for Android is down until further notice", "join the discord for the android workaround", ... might be helpful. There have been some hints (eg 1, 2) about workarounds setup and use, but as far as we can tell, web3j for android is currently broken. It appears that there might be a workaround for most, basic Android web3j functionality, even with v4.8.8-android. We'll try the discord.

Any Smart Contract/Abi to Front-End Code Generator?
Just to add: there is also web3j (https://github.com/web3j/web3j) for the Java people. You can use Maven/Gradle and it generates stubs (classes) which use can use to call the Smart Contracts on any EVM chain. And it is type-safe (as corresponding Java types are used for the Solidity types).

Does a library like web3j only work for the Ethereum network or does it work with any blockchain that uses JSON RPC?
I'm trying to build a mobile app on a blockchain and unsure if a library like web3j would work with all blockchains that use JSON RPC

Is there a clean neat way to interface with Ethereum nodes?
There really wasn’t as of about 2 years ago at least. I worked on a Clojure backend that integrated with Ethereum and went with Java interior using https://github.com/web3j/web3j which wasn’t too painful.

Where do I start in order to become the crypto dev...
Hey, I develop a crypto trading app for Android and currently started with the implementation of an Ethereum wallet using web3j. If your are interested in contribution just contact me.

Uniswap alone clears this amount. Part of the power of decentralized exchanges is that every trade is logged and publicly available, which is not something you can claim for their centralized counterparts.

97.7% of tokens launched on Uniswap were scams and rug pulls
"No one goes there anymore, it's too popular!"
Yesterday over $2.1B in volume cleared on Uniswap [0]. It's certainly useable by someone. If you want cheaper fees, try it on Arbitrum or Optimism.

Tether will not freeze Tornado Cash addresses
Somebody would! (Or rather, some thing.) There are a lot of smartcontract liquidity pools in Ethereum that facilitate trade between two tokens. The set an exchange rate by a formula that only looks at how much of each token is currently in the pool, not at prevailing market price[1].
So if and when it's apparent that Tether will be worthless, there will be a mad dash to dump it in those LPs in exchange for the other tokens, which was what happened to TerraUSD [2].
Here's a list of the LPs that have Tether as one token, just on Uniswap:
https://info.uniswap.org/#/tokens/0xdac17f958d2ee523a2206206...
[1] This as the effect of writing a persistent ITM option by the extent to which the LP's price diverge's from the market exchange rate.
[2] Here's Curve's infamous 4pool, which has TerraUSD (UST) and three other non-defunct stablecoins -- it's 97% UST now: https://curve.fi/4pool

What is the smartest anti crypto argument you've ever heard?
A quick look at some code on Uniswap, for example, shows that they use TheGraph for their statistics services - there would be no reasonable way to handle this data otherwise.

Web3 is just expensive P2P
Coinbase is a centralized exchange. Of course it runs in a SQL db or whatever. They only need to touch the chain when settling inflows/outflows.
But something like Uniswap: https://app.uniswap.org/#/swap is fully on-chain. Every trade happens on chain, because the application is an immutable smart contract liquidity protocol, called an AMM, or automated market maker.
It does as much, if not more, volume than Coinbase ($1.98B in last 24H): https://info.uniswap.org/#/

Token Info Site
Is there an Info Site for JunoSwap, like "info.osmosis.zone" or "info.uniswap.org". Thanks!

How do you view limit orders?
Go to info.uniswap.org and search for Hex and select the pool you want to look at. In the "liquidity" tab you can see how much Hex/other coin is available for buy/sell at each price level. It defaults to uniswap V3 but you can manually select V2 in the top right and do the same.

Run interface and v3-info on local geth node
how can one run interface (app.uniswap.org) and v3-info (info.uniswap.org) on the local computer, and to set provider as local node, for example geth, and not "be connected" to some external node provider? I want to be fully on my own if:

The Promise of DAOs, the Latest Craze in Crypto
Fun fact: after the DAO had essentially folded, the $PEOPLE token folks were left holding could be traded for more than 10X the value it cost to go in on the DAO.
To this day, it still trades for ~10X its initial value on Uniswap: https://info.uniswap.org/#/tokens/0x7a58c0be72be218b41c608b7...
Anyone who bought more than ~$50 of DAO tokens before the auction could stand to make a profit on the aftermarket even accounting for gas fees.
In case it needs to be said: this all seems crazy to me, but it is what it is.

My DeFi strategy in 2022 - Critique me!
And REF won't diversify across the entire L1. The REF coin staking is a bet on trading volume, not on price, and it's quite possible for coins in the ecosystem to go up in price without a lot of trading volume. If anything, a downward market causes more trading volume than an upward market: look at the graph on the right side of this page and you'll see more volume the last few days due to panic trading than in any previous weeks.
