With $50-$500 dApp interaction fees, DeFi mainly just caters to the whales
Major DeFi apps launching on Layer 2 can 10x the number of DeFi users
2021 is the year it happens
But DeFi apps will be launching across a host of different L2s - zksync, Starkware, Optimism, Matic, etc
With long or costly exit times moving between L2 to L1 to a different L2 users don't get the real DeFi UX that make it so magical
Luckily, @thorchain_org exists
People talk about Thorchain in the context of connecting other L1s, but most L2s are separate blockchains themselves that can just as well connect to Thorchain
This means that if Thorchain bridges were built for say Optimism & zksync, users would not need to go through the cumbersome process of moving to L1 first and could instead trade their Optimism coin for the same version of that coin on zksync in one tx
And since transactions on L2 are fast and cheap, so would the transaction to transfer assets between those chains
The UX for moving between chains is dramatically simplified and Arbitragers/Market makers will ensure that the version of each coin is pegged across the L2s
