Deploying Title Escrow (Joint Ownership) Contract

Recall that transferable records is held using a joint ownership structure. In this section, we will deploy a title escrow smart contract that describes the joint ownership interaction between a holder and beneficiary of a transferable record.

To help you draw parallels to the physical world:

  • the holder is the entity in physical possession of the transferable record
  • the beneficiary is the legal owner (usually printed on the document itself) of the transferable record

Both value refers to an Ethereum address which can execute different sets of actions depending on their roles.

Deploying Title Escrow Contract

Before we deploy the title escrow, we will need to identify the beneficiary and holder of the transferable record. The beneficiary and holder may be the same.

In the example, we will use 0x6FFeD6E6591b808130a9b248fEA32101b5220eca for both values. You will need to replace this value with a wallet address you control to be able to perform different actions on the transferable records later.

To deploy a title escrow contract, run the following commands:

open-attestation deploy title-escrow -f key.txt -n ropsten -b 0x6FFeD6E6591b808130a9b248fEA32101b5220eca -h 0x6FFeD6E6591b808130a9b248fEA32101b5220eca -r 0x8431012Bc040942B59e3C5bf428221eab0b2f723

Note that you have to replace the beneficiary & holder address as well as the token registry address with your own.

Once the title escrow contract has been deployed, you will see an output similar to the following:
