Write decentralized applications for Wavelet in AssemblyScript.

## Setup

Assuming `yarn` is installed, create a new smart contract project by executing the following:

```shell

yarn add -D AssemblyScript/assemblyscript

yarn asinit .

yarn add smart-contract-as

```

## Example

Inside `assembly/index.ts`:

```ts

import {Parameters, Tag, Transfer, send_transaction, log} from "../node_modules/smart-contract-as/assembly";

// Simple hello world example.

export function _contract_init(): void {

    const params = Parameters.load();

    log("hello world");

}

// Echoes back a message the sender provides.

export function _contract_test(): void {

    const params = Parameters.load();

    log("echoing back: " + params.string());

}

// Sends back half the PERLs it receives back to the sender.

export function _contract_on_money_received(): void {

    const params = Parameters.load();

    const tx = new Transfer(params.sender_id, params.amount / 2);

    send_transaction(Tag.TRANSFER, tx.marshal());

}

```
