ELI3 on rollups thing?
ELI5's on rollups are too complicated for me, need ELI3 ¯(°_o)/¯
Let's say i have some money in my crypto wallet and want to
1) send 1 ETH to a friend
2) send an ERC20 token, e.g. 100 DAI to a friend
3) swap 100 DAI to USDC via uniswap or something
it will cost me let's say $5/$15/$40 on a good day.
will zk or optimistic rollups help me to reduce these fees?
