can you please confirm deposit piggy box on other chains from kusama like Karura customer funds are safu right? Wen can you confirm deposits there are multiple piggy boxes like incorrect price feed and payment fees you can compare the customer data with your data den confirm.
Bridge Liquidity could be combined with AMM liquidity with the previously mentioned approach considering the multi chain ethereum solution makes it also easier. Combining the two solutions for multi chain liquidity pools with layer 1 security solves the two issues @VitalikButerin
There are multiple problems with liquidity pools impermanent loss, slippage and you have to split your investment this results in potential piggy boxes due to the approach to swap instead two assets from single sides liquidity pools the solution aggregate liquidity pools.
Low liquidity, impermanent loss, liquidity slippage opportunities issue
The approach to aggregate and provide multiple single sided liquidity pools is also a solution for low liquidity DEX they could reuse the liquidity from other DEXs and this is not an CEX advantage anymore.
Multichain Ethereum instead of bridged Ethereum has many advantages layer 2 scalability and transactions cost with layer 1 security. Instead of multiple ethereum tokens on multiple chains you have one ethereum token without the need for liquidity on both sides @VitalikButerin
