This package helps to create a "Plug & Play" sandbox for easy development of Pact Smart Contracts off-chain, with all standards contracts preloaded and ready.

The goal is to simulate the Kadena environment as it can be found on-chain:

• Namespaces
• Coin-contract and fungible-v2 interfaces
• Official Kadena utilities
• Third party utilities
• Marmalade interfaces and contracts

1. Make sure that the Pact interpreter in installed.

• https://github.com/kadena-io/pact/releases

2. Create your REPL file which:

• load the main sandbox script kda-env/init.repl: (load "kda-env/init.repl")
• declare or load and test your contracts

3. Optionally, you can comment some lines in init.repl to disable some features.
4. Launch your REPL file with the pact executable.

An example can be found: example.repl and example.pact and can be launched:

$ pact example.repl
Standard namespaces initialized
Kadena contracts initialized
Utils library contracts initialized
Marmalade contracts initialized
Hello bob: You have currently 1000.0 KDA
Load successful

Based on Pact 4.4.1, and currently on-chains contracts (12/02/2022)

basic-guards: Implements two simple guards (used to initialize the namespaces): GUARD_SUCCESS and GUARD_FAILURE

repl-coin-tools: Implements 2 functions to create and mint coin accounts.(env-enable-repl-natives) must be enabled to make this module work.

The following namespaces are created:

• util
• free
• kip
• user
• marmalade

There is no enabled policy, and the module ns is not loaded. There is no guard on the namespaces.

The coin contract v5 is installed.

The followings accounts are pre-funded for test purpose:

If you need more accounts, you can create a new ones with (repl-coin-tools.fund-account name key-name balance)

The version RC1 of marmalade is installed:

• https://github.com/kadena-io/marmalade/releases/tag/marmalade-rc1

Contracts:

• poly-fungible-v2 and token-policy-v1 interfaces in NS kip
• manifest contract in NS kip
• ledger in NS marmalade
• 3 default policy contracts in NS marmalade

The version 0.3 of unofficial Pact Util library:
