Cron.near Contracts

But i really really wanted to name this repo "crontracts"

Building

Run:

./build.sh

Testing

To test run:

cargo test --package manager -- --nocapture

Scripts

The following scripts automate a lot of the tedious setup for contracts, and allow for quick deployments and setup. These are scripted versions of the example commands below.

NOTE: See each script to change the main NEAR_ACCT to configure to an account you have testnet keys.

Run:

./scripts/clear_all.sh
./scripts/create_and_deploy.sh
./scripts/simple_bootstrap.sh

Power user:

export NEAR_ACCT=YOU.testnet
./scripts/clear_all.sh && ./scripts/create_and_deploy.sh && ./scripts/simple_bootstrap.sh

Create testnet subaccounts

Next, create a NEAR testnet account with Wallet.

Set an environment variable to use in these examples. For instance, if your test account is you.testnet set it like so:

export NEAR_ACCT=you.testnet

(Windows users: please look into using set instead of export, surrounding the environment variable in % instead of beginning with $, and using escaped double-quotes \" where necessary instead of the single-quotes provided in these instructions.)

Create subaccounts:

near create-account cron.$NEAR_ACCT --masterAccount $NEAR_ACCT
near create-account counter.$NEAR_ACCT --masterAccount $NEAR_ACCT
near create-account agent.$NEAR_ACCT --masterAccount $NEAR_ACCT
near create-account user.$NEAR_ACCT --masterAccount $NEAR_ACCT
near create-account crud.$NEAR_ACCT --masterAccount $NEAR_ACCT

Note: if changes are made to the contract and it needs to be redeployed, it's a good idea to delete and recreate the subaccount like so:

near delete cron.$NEAR_ACCT $NEAR_ACCT && near create-account cron.$NEAR_ACCT --masterAccount $NEAR_ACCT
near delete agent.$NEAR_ACCT $NEAR_ACCT && near create-account agent.$NEAR_ACCT --masterAccount $NEAR_ACCT
near delete crud.$NEAR_ACCT $NEAR_ACCT && near create-account crud.$NEAR_ACCT --masterAccount $NEAR_ACCT
