Context

Some Steps

Another approach

http requet cache

update: current limitation of storage slot (note : might different per account/slot)
cargo run -- encode -a -o output.json -c input.json "max" -b 4952200 4952900 "account.0x7f2c6f930306d3aa736b3a6c6a98f512f74036d4.balance" 10 is this

with error :

2024-05-10T07:18:15.905986Z ERROR hdp_provider::evm: Failed to fetch account in block 4952870: RPC request `eth_getProof` failed with status: 429 Too Many Requests

optimization and plus 429 error should be important priority to make Provider Solid
