Steps

To deploy your own copy of this Phat Contract on PoC6, clone the repository and run:

cargo contract build --release

NOTE: It requires Rust 1.73.0 and cargo-contract 3.2.

After uploading and obtaining the contract ID, you can use capture-events.ts to fetch the latest events.

# You need to install dependencies first by running `npm install`.
npx tsx capture-events.ts [contract_id]

You will see a follow-up text on the screen:

[#9087] Transfer
> from :: Option<AccountId> :: null
> to :: Option<AccountId> :: 5Deb839k2mfm44zrwP8sRLCwwHAfBEboMWCKPSaTkYbfi2FE
> value :: Balance :: 10.0000 µUnit

[#9142] Transfer
> from :: Option<AccountId> :: 5Deb839k2mfm44zrwP8sRLCwwHAfBEboMWCKPSaTkYbfi2FE
> to :: Option<AccountId> :: 5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY
> value :: Balance :: 10.0000 pUnit

You can add the -f flag to continuously poll and receive real-time updates.

npx tsx capture-events.ts [contract_id] -f

The Transfer event will be emitted when you call the transfer transaction.
