We are all underestimating how mind-bending account abstraction is, even for crypto veterans.

I've had several conversations with people who simply could not let go of the concept of seed phrases, no matter what.

2009: Private keys
2013: Seed phrases
2025: Abstract signers (passkeys, ZK proofs, oracles, anything!)

It’s interesting to see this effect since we’ve had native account abstraction on some rollups for a long time now (starknet, zksync, probably others).

Tricks with polynomials and Riemann-Roch spaces. Breaking into the platonic realm to pillage forbidden abstractions. Starknet grantee.

A great example is current Eternum season on starknet:
- sign up using passkey, discord, wallet connect
- pay for season pass with crypto or credit card
- create session key for game play so you dont have to approve all transactions (a lot since it’s fully onchain game)

Being able to sign up with discord and pay for season pass (nft) and in game currency (erc20) with credit card makes the experience seamless for someone coming from web2 just wanting to play.
