Account abstraction

Account abstraction is the umbrella for making wallets programmable — sponsored gas, batched calls, scoped keys, and passkey signatures — instead of every transaction being signed by one externally owned key. Robinhood Chain treats it as a first-class concern, supporting both ERC-4337 (with published EntryPoint addresses for v0.6–0.8) and EIP-7702 delegation, which suits a chain aimed at agentic and app-embedded trading.
