This is a program that facilitates peer to peer bets on the price of an asset. The bets will be decided by a switchboard price feed.

The program currently contains the method resolve_bet_local_test_dummy which is a dummy method to be able to run unit tests on localnet. This method must be removed before deploying the program to mainnet or doing a serious test run on devnet.

Make sure that the cluster in Anchor.toml is set to localnet.

anchor test

The tests go through all the program methods. The resolve step however uses the mock implementation that needs to be removed in the future to go over this step without the not available switchboard program and to enable the ability to test claiming of the winnings that can only be done after the resolve step.

First make sure that the cluster in Anchor.toml is set to devnet.

If a new instance of the program is required, the following commands should be run:

anchor build
anchor deploy

Make sure to update the program id where necessary in this case.

First make sure that the cluster in Anchor.toml is set to devnet. On localnet the switchboard program is not available.

Make sure to add admin.json, maker.json and taker.json to the /scripts/wallets/ folder. Those are wallets in byte array format. The wallets need to be prefunded on devnet. The scripts only work fully on devnet, not localnet, since switchboard is not present on localnet.

Install the yarn project dependencies

yarn

All the input parameters for the scripts are in the /scripts/99-config.ts file and are exported to the other scripts. So if there is a change in this file, all scripts will pick up on those changes.

In the 'keypairs' section the wallets that were added in the previous step are imported as keypairs. All of those three keypairs are used in the scripts.

In the 'init program' section, the init seed and the fees are set. The seed helps if a single wallet wants multiple instances of this program initiated. The fees determine the percentage of the betting pool that goes to the treasury.

In the section 'bet' the actual bet can be configured.

Switchboard defines the price feed and the program id for switchboard on the used chain. Since the sdk seems to have issue to figure out whether the task is run on mainner or devnet, manual settings are used for this set of scripts instead of relying on the sdk to provide this address. The price feed address defines which feed will be used to resolve the bet in the end.

To allow to use these scripts on programs instances that are not setup by the admin wallet, bet program and treasury can be set manually.

First the 'casino' instance need to be initialized. Before this no bet can be created.

yarn init-program

For the bet to be created, there must not be an active bet from the same creator, using the same seed.

yarn create-bet

To accept a bet, the bet must be active and within the allowed time window.

yarn accept-bet

If a bet is accepted and the point in time has passed, that marks the end of the bet, the bet can be resolved.

yarn resolve-bet

Once a bet is resolved, the winner can claim the price money.

yarn claim-bet

If a bet is not accepted yet, it can be cancelled by the creator.

yarn cancel-bet

If the casino's treasury is not empty, the treasury can be claimed by the admin.

yarn claim-treasury
