Migrate internals to viem (from ethers)

[holic]

viem is shaping up to be a rock solid library with incredible benchmarks over ethers. It's strongly typed, well tested, and maps closely to RPC calls and other Ethereum-native operations, and only does what you ask it to (unlike ethers that ends up doing a lot more work than is often necessary, hence benchmarks).

I've already used it in some personal projects and loving the speed/performance + predictability.

Rough plan:

• Migrate v2 store event decoding to viem
• Migrate v2 store event ingestion (rpc calls) to viem
  • We'd still lean on ethers providers for v1 things
• Build new v2 client code on top of viem

In the future:

• Use viem + wagmi for wallet connection/account delegation (pending wagmi migrating to viem)

I think a good idea here might be to wait til wagmi cli has viem plugin support. Then you will be able to generate viem/wagmi wrappers automatically from the cli for all contracts

This is ongoing and mostly done, things are looking quite promising! I've finally got a full WIP (#1033) running on just viem + new network packages + store-cache and we can call contracts with viem directly.
