M3mber: I think this is a way to mint an NFT that represents a membership in something with an expiry date (pitched as a way for DAOs to bring in recurring money like a subscription rather than just the one-off token sale). They use ENS domains, with NameWrapper to accomplish this; is it only because ENS domains already have expiry built in so they don't have to code it from scratch?

I came across this helper function to find a string length present at https://github.com/ensdomains/ens-contracts/blob/master/contracts/ethregistrar/StringUtils.sol And I couldn't understand what this piece of code is doing uint bytelength = bytes(s).length; for(len = 0; i < bytelength; len++) { bytes1 b = bytes(s)[i]; if(b < 0x80) { i += 1; } else if (b < 0xE0) { i += 2; } else if (b < 0xF0) { i += 3; } else if (b < 0xF8) { i += 4; } else if (b < 0xFC) { i += 5; } else { i += 6; } } return len; Any help is appreciated. Thank you

Which bridge have you tried so far? I have good experience with these: hop.exchange and app.optimism.io/bridge

What do you mean by that? Running validators on L2 won't ever be possible. If you want to buy rETH, you can do so on L2s directly via Uniswap. Hec, since yesterday you can even do fast and secure bridging via https://hop.exchange for rETH! RPL was also recently deployed on L2s (Arbitrum and Optimism), but uniswap hasn't yet added the token images.

I save money by not going to L1 in the first place. And if you want to switch between L2s, there is always Hop (https://hop.exchange) which is a secure cheap and fast bridging option

And checkout Hop (https://hop.exchange) where you can securely migrate funds between different L2s directly.

For (2) a collab with hop.exchange is in the work:

I'm a huge fan of https://hop.exchange. I've had a bunch of talks with the founders, Chris and Shane, and I find them to be highly aligned with Ethereum values. I honestly don't know if it's cheaper (?) but I do know that "cheapest" and "best" aren't always the same.

Actually looking at it further all contact email addresses are at hop.exchange rather than the hopusdc.org so smells like a scam..

hop.exchange can do this quickly to get ETH from Arbitrum to Mainnet. Keep in mind all collateral on dYdX is USDC, so any ETH you put into your trading account at dYdX will be exchanged at the time of deposit.
