Upgrading Smart Contracts

This tutorial covers how to upgrade a smart contract. This procedure will focus on updating a smart contract for Grid on Splinter run using the Docker compose file located in grid/examples/splinter.

There are two sets of tasks associated with upgrading a smart contract. The first set will likely be done by a developer working on the smart contract itself and will be covered in this section. The second set will likely be done by an administrator to actually deploy the smart contract. This document can be found in the Upgrading Smart Contracts for Administrators section.

Procedure

Update the Smart Contract

This set of steps will likely be done by a developer working on the smart contract code. These steps increment the protocol version of the smart contract alongside functional changes and get the smart contract ready for deployment.

1. Update the manifest.yaml and <contract_name>.yaml files for the smart contract with updated inputs, outputs, and increment the protocol version number.

2. Increment the family version constants for the Smart Contract in the following files:

   • grid/cli/src/transaction.rs

   • grid/contracts/<contract_name>/src/handler.rs
