What is asset tokenization, and what does it leave unchanged?
Tokenization takes a claim on an asset that exists off-chain, such as a share in a money market fund, a bond or a building, and issues a digital token on a blockchain that represents that claim. The token can be held in a wallet, transferred between approved parties and used inside smart contracts. The asset itself does not move. What moves is the record of who owns it, from a registrar's database to a shared ledger.
What tokenization does not change is the asset. A tokenized fund share is still a security, subject to the same registration, disclosure and eligibility rules. Tokenization generally does not by itself change the economic exposure of the underlying instrument, but the token's legal rights, fees, liquidity, custody and operational risks depend on the specific structure and offering documents.
The token is only as good as the legal claim behind it. Read the offering documents before you read the smart contract; the first tells you what you own, the second tells you how the record of it is kept.
