Smart accounts and account abstraction for institutions

Two Ethereum standards let an account enforce spending policy and delegate narrow permissions instead of relying on one bearer key. They differ in design, in how they reached mainnet, and in where compromises have happened.

How digital assets actually land in the financial statements

The question a chief financial officer asks first, answered with the standards themselves: fair value under ASU 2023-08, the IFRS split between IAS 2 and IAS 38, where tokenised securities land, and what an auditor accepts as evidence of existence and rights.

Who actually controls a protocol, and why it belongs in diligence

Before capital goes into a protocol, three questions decide the risk: who can change the code, how quickly, and what stands in the way. The answers are public integers, named multisig signers and measurable voting concentration, and almost all of them can be read straight off the chain.
