SWEAT DeFi Jar

$SWEAT staking smart contract.

---

1. Exploring the project

• Read the Product description.
• Read the Project documentation page.

2. Quickstart

1. Make sure you have installed rust.
2. Install the NEAR CLI

If you already have rustup installed, you can ensure that the correct version of the compiler and the NEAR CLI is installed as well:

make install

2.1. General information

To learn how to build the project, deploy it, and run tests run the following command:

make help

2.2. Build and Deploy the Contract

First build the contract using provided make command:

make build

Then deploy and initialize it. Rename dev.env.example to dev.env and define variable values there. To deploy the contract to dev-account on Testnet use the following command:

make deploy

Once finished, check the neardev/dev-account file to find the address in which the contract was deployed:

cat ./neardev/dev-account
# e.g. dev-1659899566943-21539992274727

2.3. Reproducible build

If you build your contract on two different machines, it's highly likely that you'll obtain two binaries that are similar but not exactly identical. Your build outcome can be influenced by various factors in your build environment, such as the locale, timezone, build path, and numerous other variables.

To obtain an identical build artifact on any machine, matching the one deployed on NEAR, you can build it using Docker:

make build-in-docker

3. Measure gas consumption

Integration tests crate contains measure module which can be used to measure required amount of gas for each method.

3.1. To measure a single call you need to:

• Create a method: (Input) -> anyhow::Result<Gas>.
• In this method prepere context and everything required for the call.
• Wrap the call you want to measure in OutcomeStorage::measure.
• Pass a label, it is any text which can be found in logs of this method and identify it.
• Pass calling account id.
• Return Gas value returned by OutcomeStorage::measure.

See example: integration-tests/src/measure/withdraw.rs::measure_one_withdraw.

3.2. To measure calls with different data:

• Use generate_permutations method for generating all possible value combinations you want to test.
• Pass the data and your method to scoped_command_measure, it will collect all the data and return the report for each call and permutation.

See example: integration-tests/src/measure/withdraw.rs::measure_withdraw_test.
