Smart contract to transfer an authority of assets to other User.

Question

Basically I just want to implement a smart contract which has some set of rules between two user.Assets can be issued to the other user by digitally signing the contract by both end user (user1: currently owner of asset, user2: Next owner of the Asset).

Answer 1

You could use a transaction filter and follow the pattern in this example:

https://github.com/MultiChain/smart-filter-examples/blob/master/transaction-filters/approve-asset-transfer.js

But instead of pre-approvals being created by users with a custom low1 permission, you want to ensure that the pre-approval must be created by the user who is meant to received the assets.
