First, a little context:
This week we launched CryptoFlows.info, a site that tracks how value flows between different blockchains and which bridges facilitate this.
We take a wide definition of a "bridge", including fully-custodial assets like WBTC and Binance-Pegged ETH.

L2 rollups have promised to let anyone use Ethereum, with low transaction fees.
However, rollups are still more expensive than many low-fee chains. Can this be fixed?
Let's run a little experiment with calldata and see how much we can lower these fees! l2fees.info/blog/rollup-ca…
If this is interesting, make sure you check the full blog post (l2fees.info/blog/rollup-ca…). I think this is the first blog post with a built-in dapp!
OpenOrgs launched early this year as a dashboard for showing the largest DAOs by treasury size. But with this update, it can grow into a more all-encompassing hub for all DAOs.
Check out some of the new stuff: ⤵️
After OpenOrgs launched last time, many people pointed out that many of these treasuries were mostly their own governance token locked in a vesting contract.
OpenOrgs now splits the "Total Treasury" (which includes vesting tokens) from the Liquid Treasury.

It's day 5: the final day of ERC-777 week! 🎰🎉
This week we've discussed the pros & cons of the ERC-777 token standard. Today I'll cover things that developers should know about to build with ERC-777, and what the next steps are for this standard.
The most popular of these is permit(), which was originally created for Dai, and popularized in Uniswap V2.
Permit allows a the user to sign a message before their transaction, giving another contract permission to "pull" tokens. This signature gets included in the main tx.

🎉🎰It's ERC-777 week! 🎰🎉
With the upcoming launch of optimistic rollups & some recent hacks, it's time to put some focus back on my favorite token standard!
Every day this week, I'll post a thread about ERC-777 and answer any questions about it
Today: an intro to ERC777 ⤵️
I like to think of ERC777 as ERC20 2.0
ERC-777 is a standard for fungible tokens, and it's fully backwards-compatible with ERC-20. It works with any existing wallet, but also adds new features.
For more details, check out this thread I made last year:

(1/10) The imBTC/Uniswap hack took advantage of the ERC777 standard, now I'm seeing many people saying that ERC777 is inherently bad or unsafe.
ERC20 is safer than ERC777 in the same way that Bitcoin is safer than Ethereum. It's safe because it's limited.
Here's some thoughts:
(2/12) First of all, for anyone that isn't familiar with ERC-777, you can think of it as ERC-20 2.0. It's a token standard that's backwards compatible with ERC-20, but adds some new features.
