Protocol-Specific Projects
Disclaimer: This is a new frontier of money. These change all the time. What I have listed here are protocols that I use. Better ones may pop up. I am a degen with a mostly work-from-home white collar computer job so I research this sh!t all the time, and I can barely keep up.
EVM
You can use the same wallet addresses across all EVM chains. It's better practice to use different ones for each project, but you will have the same set on each: if you have the ETH address 0xbassyjackbootsbanhammer, you will also have a BSC address 0xbassyjackbootsbanhammer, a MATIC address 0xbassyjackbootsbanhammer, etc.
Ethereum
Tons of Defi projects, but I don't use them, because gas fees are too high. However, most of the big names in the EVM space originally developed on ETH, so you'll see them throughout here - Curve, AAVE, Badger, Uniswap, Sushiswap. Most of what I use ETH for is bridging tokens to cheaper chains.
Because Coinbase Pro is the easiest US centralized exchange and will only let you withdraw USDC on ETH, it's the starting point to get money into most ecosystems.
Curve will get mentioned a lot - it's a gold standard project across multiple blockchains with good coding. Curve is designed as a low-slippage stablecoin pool for large transactions. Its native token is CRV, which has doubled recently.
BSC
How to get money onto and use BSC
Buy BNB for gas on Binance.us or Binance.com (Americans may be able to use through a VPN)
Install Metamask and add Binance Smart Chain protocol through instructions on binance.org
Bridge money from other chains via Binance Bridge (US use VPN), Anybridge, Allbridge, Wormhole, Terra Bridge, etc. Many options.
Transactions on BSC cost anywhere from a few cents to a few dollars, depending on complexity.
Protocols
PancakeSwap and MDEX are the main liquidity pool sites. BELT is a single-token lending and low-slippage stablecoin LP site. Beefy and Autofarm are autocompounders. Autocompounders work by harvesting the farming rewards, selling them off, and reinvesting the proceeds back into the pool.
One worthwhile stablecoin strategy:
-Deposit stablecoins in BELT's 4BELT pool, which is a USDC/USDT/DAI/BUSD pool. You will get 4BELT LP tokens that show your stake.
-Do not stake! If you stake, you will get paid rewards in BELT, which is essentially useless.
-Instead, deposit the 4BELT LP tokens into Beefy or Autofarm, which will autosell the BELT and reinvest.
This has historically returned 15-22% or so APY.
Polygon (MATIC)
How to get money on, use
MATIC is the token. You can get free MATIC to run a few transactions from MATIC faucets, so no need to buy right off the bat. You can also buy MATIC on exchanges.
Install MATIC Mainnet on Metamask.
Bridge money from ETH using the built-in Polygon Bridge
https://wallet.polygon.technology/ or from other chains using third party bridges (Allbridge goes to SOL and BSC).
Protocols
Quickswap is the LP/exchange.
Curve is the most worthwhile player. You need to connect to
polygon.curve.fi. Curve.fi is the ETH version. There's no link back and forth.
Two good pools on Polygon Curve:
aave is a stablecoin-only pool with USDC, USDT, and DAI.
Returns have been in the 12-20% range.
atricrypto3 is a stablecoin/BTC/ETH pool. The advantage here is that you get hedged exposure to BTC and ETH as well as returns on the deposits. It's BTC/ETH/USDDC/USDT/DAI.
Farming returns - not counting increases in BTC/ETH price - have been in the 18-35% range.
You can also deposit these into the Beefy or Autofarm autocompounders to sell the CRV and WMATIC rewards.
FTM and AVAX I haven't used enough to recommend anything.
Non-EVM
Solana
Getting money to, using Solana
Install Phantom wallet client.
Buy SOL on Coinbase Pro or other exchanges. A Solana transaction costs 0.000005 SOL, so you don't need much to get started.
Option 1: Bridge USDC, USDT, or UST to Solana through Wormhole from ETH/BSC/Terra. You can also bridge ETH/BNB/LUNA/BTC, Solana has support for a lot of wrapped tokens.
Option 2: Buy SOL on CBP, withdraw to Solana, swap on DEX for USDC (probably cheapest fiat to stablecoin on Solana route)
Projects:
Mango.markets has a single-token lending platform as well as other uses. You can deposit and borrow USDC, USDT, SOL, ETH, BTC, and other tokens. Interest rates vary wildly depending on the utilization curve of the asset. They go apeshit in the low 70s - that is, once about 70+% of the specific token is borrowed, rates climb very quickly.
https://trade.mango.markets/stats shows the numbers.
Raydium is a combination interface to Serum, which is a decentralized exchange, plus a liquidity pool/farming project.
Saber and Mercurial have low-slippage stablecoin LPs with farming rewards. Rewards bounce around a lot on Saber, so you have to keep on top of it.
Sunny Aggregator is a autocompounder for Saber that also adds SUNNY tokens as an additional farming reward.
Terra
Getting money to, using
Install Terra Station wallet and extension
Buy LUNA on exchanges
Bridge UST from ETH or BSC using Terra Bridge or from Solana using Wormhole
Protocols
Terra is starting to explode, but has two main protocols leading the pack.
Anchor is a traditional bank-style deposit and earn protocol. It offers a steady interest rate that attempts to hit 20% APY on UST deposits. It hasn't hit 20% in a while, but it also hasn't gone below the high 17s and
usually sits around 19.5%. You can also insure Anchor deposits for a fairly low rate, indicating that the crypto world considers it pretty safe.
Mirror is a tokenized "mirror world" stock platform where you can buy tokenized versions of blue-chip stocks and hold them onchain. You can farm the UST-stock pools on both the long and short side for rewards in the MIR native token.
The long pools that I follow - NFLX, SPY, GOOG, COIN - tend to return farming rewards in the 20-30% range. You also have exposure to the underlying stock/fund. It's basically the equivalent of getting a dividend on a non-dividend stock.
Mirror and Anchor both use UST for gas. You don't actually need to hold LUNA to use either, although you do need LUNA to bridge money in and out or move it anywhere else.
Added Bonus!
Terra projects almost always airdrop free governance tokens to wallets that stake the native LUNA token for validation. An airdrop is just a giveaway of tokens. In other words, if you hold and stake LUNA, you get free money from other projects that are starting out.
