Blockchains are fast and and cheap now! Modern blockchains like Base, Solana, Sui (and many more) typically have block times <2 seconds, and a stablecoin transfer can cost as little as $0.0005 independent of the $ amount being transfered

Yeah, it's mostly bitcoin that's slow. SOL is sub-second, AVAX has a new architecture that has gone from a few seconds to sub-second, and while I have never used SUI I believe that one too is sub-second. ETH is still relatively slow, but not bitcoin slow.

> Are crypto payments instant now ?

Practically speaking yes.

There are now chains with sub-second Time to Finality and sub-cent gas fees (this was not true ~3 years ago)

Which chains have sub second block times?

SOL, AVAX, SUI

Thanks

Block time != time to finality

Base has sub-second block times, but because it's an Ethereum L2, it technically has ~15min TTF
