That's step 1
I'm sure someone else has explained this, but it is just so cool and I want to explain how this works.

That's step 1
Swap $1m sUSD for $1m sBTC? flat 0.3% fee
Swap $10m sUSD for $10m sBTC? flat 0.3% fee
swap $100m sUSD for $100m sBTC? Well, there isn't that many synths in Curve, yet but you get the point. The only limit is the pool depth
1. Curve lets you swap like-assets with extremely low slippage and a low fee
2. Synthetix lets you convert synths to other synths, with no slippage and a low fee
What happens if we just... combine them?
1. I swap my "real asset" (e.g. USDC) for a "synthetic" one (e.g. sUSD)
2. I exchange one synthetic asset for another (e.g. sUSD -> sBTC)
3. I swap my new synthetic asset to a "real" asset again (e.g. wBTC)
It is. It's not cheap either, at over 1m gas to execute. And to make matters worse, due to how a Synthetix swap works, you actually have to wait a few minutes between the swap, so it isn't even full atomic!
The answer is capital efficiency. AMMs with a curve that allows trading assets that are dissimilar are inefficient with larger and larger swaps.
For example, a $10m USDC -> wBTC swap on Uniswap right now has >13% slippage!
Of course you would pick this option now!
But on principle, this will be the best way to perform a high-value swap!
I think as we have seen, gas fees are just going up and up and up. Optimism soft-launched their L2 today, but Ethereum's success means that block space will always be at a premium.
The gas costs will not be coming down as much as you'd think!
This more efficient means of large-value swaps will see a lot of use on base layer Ethereum, as gas prices continue to grow.
Hobbyist/frequent traders will move to Layer 2, where smaller value trades will be economically more efficient.

1/ ERC-20 token standard approve() has caused an unnecessary cost of $53.8M for #Ethereum and #DeFi users
This is bad. Continue reading why and how to avoid this in the future.

2/ Before you go all rage on the flaws of my analysis, please read the whole Twitter thread for disclaimers and caveats.
3/ approve() is an unnecessary step of ERC-20 tokens when they interact with smart contracts.
You know this because when you do a Uniswap trade you need press two transaction buttons instead of one.
4/ Why there is approve() - you can read the history in this Twitter
5/ I queried all approve() transactions on Google BigQuery public dataset and calculated their ETH cost and then converted this to the USD with the current ETH price.

Q1 - What are the benefits of holding the $VALUE token on the Ethereum Mainnet network? Give me reasons not to sell. Some are assuming that the VALUE token will be abandoned now that vBSWAP is being created. Can you clarify the use case for VALUE?
👉 $VALUE will always be a governance & profit receiving token of the whole ecosystem if staked in #vGov. With the new farming token on #BSC , gvVALUE holders will get extra rewards at BSC if they choose to bridge their gvVALUE to BSC & stake in gvVALUE-B/BUSD 98/2 pool.
Q2 - What do I need to do with my VALUE tokens that are staked in vGov? Is it OK to leave them in the vGov?
👉If you have VALUE but aren't staking in the vGov & you would like to participate in the BSC expansion, you will need to stake your VALUE in the vGov to receive gvVALUE.
If you are staking in vGov but don't see the correct gvVALUE amount in your wallet, go to vGov (https://t.co/udXn5IJtVx) to unlock your gvVALUE from the old contract. There will be a bridge from ETH to BSC to move gvVALUE and vUSD over.

Out of curiosity I dug into how NFT's actually reference the media you're "buying" and my eyebrows are now orbiting the moon
Short version:
The NFT token you bought either points to a URL on the internet, or an IPFS hash. In most circumstances it references an IPFS gateway on the internet run by the startup you bought the NFT from.
Oh, and that URL is not the media. That URL is a JSON metadata file
Here's an example. This artwork is by Beeple and sold via Nifty:
https://t.co/TlJKH8kAew
The NFT token is for this JSON file hosted directly on Nifty's servers:
https://t.co/GQUaCnObvX
THAT file refers to the actual media you just "bought". Which in this case is hosted via a @cloudinary CDN, served by Nifty's servers again.
So if Nifty goes bust, your token is now worthless. It refers to nothing. This can't be changed.
"But you said some use IPFS!"
Let's look at the $65m Beeple, sold by Christies. Fancy.
https://t.co/1G9nCAdetk
That NFT token refers directly to an IPFS hash (https://t.co/QUdtdgtssH). We can take that IPFS hash and fetch the JSON metadata using a public gateway:
