Ethereum Account Abstraction

I've gotten a bunch of questions on smart wallets vs. MPC recently — took some time to write up how I think about it.

@base builder #001; onchain cities w/ OAK & city3

But if secret is divided into N parts and distributed to N validators in MPC
T is the threshold number of validators that can decrypt the secret
T is a subset of N
No way to prove if T validators colluded and decrypted the secret even economic incentives don't solve this problem. It won't work without ZK, FHE or TEE
