# kaal:claim:4900878-031

**Claim.** In blockchain transactions the signing function, performed by wallets holding cryptographic keys, is separate from execution, which occurs inside the smart contract, so tokens are never physically held in the same locality as the keys and the smart contract acts as the intermediary executing predefined rules.

**Type.** definitional  **Support.** asserted

**Holds when.**

- smart contract based blockchain transactions

**Source quote.**

> This separation ensures that the tokens themselves are not physically held in the same locality as the keys.
