 Assets on Stellar have two identifying characteristics: the asset code and the issuer. Since more than one organization can issue a credit representing the same asset, asset codes often overlap (for example, multiple companies offer a USD token on Stellar). Assets are uniquely identified by the combination of their asset code and issuer.
 
-You can also create smart contract tokens using the [Token Interface](https://soroban.stellar.org/docs/reference/interfaces/token-interface) but it is possible, and even recommended in most cases, to [wrap a Stellar asset](#wrapping-stellar-assets) using the Stellar Asset Contract for use in smart contracts.

 The public key of the issuing account is linked on the ledger to the asset. Responsibility for and control over an asset resides with the issuing account. Since settings are stored at the account level on the ledger, the issuing account is where you use set_options operations to link to meta-information about an asset and set authorization flags.

+Assets issued on the Stellar network are accessible to smart contracts. Every Stellar asset has reserved a Stellar Asset Contract that can be deployed by anyone who wants to be able to interact with the asset from a contract.
 
-Assets issued on the Stellar network can be used in smart contracts with the Stellar Asset Contract (SAC), which is an implementation of [CAP-46-6: Smart Contract Standardized Asset](https://github.com/stellar/stellar-protocol/blob/master/core/cap-0046-06.md). The SAC allows users to use their Stellar account and trustline balances in Soroban and is a primary intersection where smart contracts interact with the rest of the Stellar network.
+The Soroban CLI can deploy a Stellar Asset Contract for a Stellar asset. Deploying the Stellar Asset Contract for a Stellar asset enables that asset for use with smart contracts.

+Custom token contracts can be deployed on Stellar by deploying a contract that implements the [Token Interface](https://soroban.stellar.org/docs/reference/interfaces/token-interface), which is the same interface implemented by the [Stellar Asset Contract (SAC)](https://soroban.stellar.org/docs/tokens/stellar-asset-contract) for Stellar assets.
