# Svelte-Contracts

## About

svelte-contracts is a library to easily create and manage [web3 contracts](https://web3js.readthedocs.io/en/v1.2.11/web3-eth-contract.html) as [svelte readable stores](https://svelte.dev/docs#run-time-svelte-store-readable).

## Installation

npm install svelte-contracts

## Usage

### Create your own contracts

```js

import { createContract } from 'svelte-contracts';

const ERC20Token = createContract('0x95ad61b0a150d79219dcf64e1e6cc01f0b64c4ce'); // from etherscan.io

const symbol = await ERC20Token.methods.symbol().call();

console.log(symbol);

Output: 'SHIB'

```

### Use prebuilt contracts

**Note: you must be connected to the blockchain to use any prebuilt contracts. Try [`svelte-web3`](https://www.npmjs.com/package/svelte-web3).**

```js

import { supported } from 'svelte-contracts';

console.log(supported);

Output: ['USDT', 'USDC', 'BUSD', 'UNI', 'UST', 'DAI']

```

```js

import { USDC, USDT } from 'svelte-contracts';

await USDC.methods.transfer('0x7b76229515d374a537360BDFE1504aF5EE04c415').call();

await USDC.methods.approve('0x7b76229515d374a537360BDFE1504aF5EE04c415').call();

```

## Docs

### `createContract(address, ABI=ERC20ABI)`

#### `address` - blockchain address for the contract (found on 3rd party sites like Etherscan.io)

#### `ABI` - (optional) defaults to ERC20ABI which can be found [here](https://ethereumdev.io/abi-for-erc20-contract-on-ethereum/). Provide your own ABI as JSON if you want more functionality.
