1 | # Dynamic NFTs
2 | This repo will support the [Creating Dynamic NFTs](https://www.youtube.com/watch?v=E7Rm1LUKhj4) tutorial.
3 |
4 | ## How to Use The Repo
5 |
6 | This repo consists of two files:
7 | - **1_starter.sol**: This is the starter file with the basic OpenZeppelin contract plus helper functions
8 | - **2_complete.sol**: the final contract for use with keepers
9 |
10 | Both versions of the contracts can be deployed as is via a tool like [Remix](https://remix.ethereum.org/).

1 | # Dad Jokes On Chain
2 | > Dad jokes, they used to be off the chain.
3 |
4 | **_TODO: YT LINK_**
5 | This repo supports the tutorial [Dad Jokes On Chain]()
6 |
7 | ## How To Use The Repo
8 | The repo is broken into 2 main sections via folders
9 | **smartcontract**: This folder contains a foundry project with the smart contract which will hold the dad jokes and any reward that has been given to them.
10 |
11 | **frontend**: This folder contains the next.js project which will act as the front end for interacting with the smart contract.
12 |
13 | ### Running the frontend
14 | Clone the repo and then run `npm install` within the next folder. Once that completes you can start the front end via `npm run dev`

4 | ## How to Use The Repo
5 |
6 | The repo is broken down into 3 main sections via directories
7 | ___
8 | _**foundry & svelte**_ : The initial setup to get started consists of the foundry and svelte directories.These directories have Foundry and SvelteKit setup with a basic installation and a few nice to haves installed.
9 | - ethers.js
10 | - OpenZeppelin Contracts
11 | - remappings.txt
12 | - .gitignore
13 | - Some VS Code tweaks to keep track of editors
14 |
15 | _**foundry_final**_ : Completed smart contract ready to be used and create your EmojiGotchi NFT
16 |
17 | _**svelte_final**_ : The final app in it's completed form. Run via `npm run dev` or deploy to the host of your choice

2 |
3 | ### UpkeepInteractions.sol
4 |
5 | A solidity contract showcasing the interaction with `AutomationRegistrar` and `KeeperRegistry` contracts, for **registration** of **Custom Logic Upkeep** and performing other operations like **pause upkeep**, **unpause upkeep**, **cancel upkeep**, **add funds to upkeep**, **withdraw funds from upkeep**, and **edit gas limit of upkeep**.
6 |
7 | **Note:** The upkeep that will be registered using the contract won't be visible in the [Automation UI](https://automation.chain.link/) because the `adminAddress` is being set to the address of the contract (not to any wallet).
8 |
9 | ### upkeepInteractions.js
10 |
11 | A script in JS containing the functions to interact with the registered **Custom Logic Upkeep**.
12 |
13 | Run the script using this command:
14 |
15 | ```js
16 | node upkeepInteractions.js ${KEEPER_REGISTRY_ADDRESS} ${LINK_TOKEN_ADDRESS}

2 |
3 | This project is an example of a command-line interface (CLI) that uses the [functions-toolkit](https://github.com/smartcontractkit/functions-toolkit) to interact with Chainlink Functions.
4 |
5 | ## Installation
6 |
7 | To set up the project, follow these steps:
8 |
9 | 1. Clone the repository.
10 | ```bash
11 | git clone https://github.com/smartcontractkit/functions-example
12 | ```
13 | 1. Clone the repository.
14 | ```bash
15 | cd functions-example
16 | ```
17 | 1. Install the required dependencies.
18 |
19 | ```bash
20 | npm install
21 | ```
22 |
23 | 1. We use [@chainlink/env-enc](https://www.npmjs.com/package/@chainlink/env-enc) package to encrypt environment variables at rest. Set the password to encrypt and decrypt the environment varilable file `.env.enc`:
24 |
25 | ```bash
26 | npx env-enc set-pw
27 | ```
28 |
29 | 1. Set the following variables:
30 |
31 | - PRIVATE_KEY
32 | - ETHEREUM_SEPOLIA_RPC_URL
33 |

5 | ## Creating a project
6 |
7 | If you're seeing this, you've probably already done this step. Congrats!
8 |
9 | ```bash
10 | # create a new project in the current directory
11 | npm init svelte
12 |
13 | # create a new project in my-app
14 | npm init svelte my-app
15 | ```
16 |
17 | ## Developing
18 |
19 | Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
20 |
21 | ```bash
22 | npm run dev
23 |
24 | # or start the server and open the app in a new browser tab
25 | npm run dev -- --open
26 | ```
27 |
28 | ## Building
29 |
30 | To create a production version of your app:
31 |
32 | ```bash
33 | npm run build
34 | ```
35 |
36 | You can preview the production build with `npm run preview`.
37 |
38 | > To deploy your app, you may need to install an [adapter](https://kit.svelte.dev/docs/adapters) for your target environment.

1 | # Setting a gas price threshold on Chainlink Automation upkeeps
2 |
3 | This project provides a script you can use to configure and set a maximum gas price for your Automation upkeep.
4 |
5 | ## Installation
6 |
7 | To set up the project, follow these steps:
8 |
9 | 1. Clone the repository:
10 | ```bash
11 | git clone https://github.com/smartcontractkit
12 | ```
13 | 1. Navigate to the directory for this script:
14 | ```bash
15 | cd automation-gas-threshold
16 | ```
17 | 1. Install the required dependencies:
18 |
19 | ```bash
20 | npm install
21 | ```
22 |
23 | ## Usage
24 |
25 | 1. Set the following variables:
26 |
27 | - YOUR_RPC_URL: The RPC URL for your provider (such as Alchemy or Infura)
28 | - YOUR_PRIVATE_KEY: Your wallet's private key
29 | - YOUR_UPKEEP_ID: The ID of the Automation upkeep you want to configure.
30 |
31 | 1. Within the `offchainConfig` variable, set your `maxGasPrice` in wei. Do not use
32 | quotation marks around the value you set for `maxGasPrice`. If this string
33 | is formatted incorrectly, the feature does not work.
34 |
35 | `{"maxGasPrice":2000000000}`
36 |
37 | 1. Run the script:
38 | ```bash
39 | node index.js
40 | ```

/vrf-arbitrum-gas-estimation/README.md:
--------------------------------------------------------------------------------
1 | # VRF / Arbitrum gas estimation tutorial
2 |
3 | This extends the [**original Arbitrum gas estimation tutorial**](https://github.com/OffchainLabs/arbitrum-tutorials/tree/master/packages/gas-estimation) to add [gas estimate calculations for Chainlink VRF](https://docs.chain.link/vrf/v2/estimating-costs#arbitrum).
4 |
5 | ---
6 |
7 | # Gas estimation tutorial
8 |
9 | `gas-estimation` is a simple demo of how a developer can estimate transaction fees on Arbitrum.
10 |
11 | It uses the formula described in this Medium article to estimate the fees to be paid on a transaction, also estimating each component of the formula separately: [Understanding Arbitrum: 2-Dimensional Fees](https://medium.com/offchainlabs/understanding-arbitrum-2-dimensional-fees-fd1d582596c9).
12 |
13 | See [./exec.ts](./scripts/exec.ts) for inline explanations.
14 |
15 | Inside the script, you can edit `txData` constant to suit your needs.
16 |
17 | To run:
18 |
19 | ```
20 | yarn run exec
21 | ```
22 |
23 | ## Config Environment Variables
24 |
25 | Set the values shown in `.env-sample` as environmental variables. To copy it into a `.env` file:
26 |
27 | ```bash
28 | cp .env-sample .env
29 | ```
30 |
31 | (you'll still need to edit some variables, i.e., `L2RPC`)

/dadjokes-onchain/frontend/README.md:
--------------------------------------------------------------------------------
1 | This is a [Next.js](https://nextjs.org/) project bootstrapped with [`create-next-app`](https://github.com/vercel/next.js/tree/canary/packages/create-next-app).
2 |
3 | ## Getting Started
4 | First, install everything
5 | ```
6 | npm install
7 | ```
8 |
9 | Then, run the development server:
10 |
11 | ```bash
12 | npm run dev
13 | # or
14 | yarn dev
15 | # or
16 | pnpm dev
17 | # or
18 | bun dev
19 | ```
20 |
21 | Open [http://localhost:3000](http://localhost:3000) with your browser to see the result.
22 |
23 | You can start editing the page by modifying `app/page.js`. The page auto-updates as you edit the file.
24 |
25 | This project uses [`next/font`](https://nextjs.org/docs/basic-features/font-optimization) to automatically optimize and load Inter, a custom Google Font.
26 |
27 | ## Learn More
28 |
29 | To learn more about Next.js, take a look at the following resources:
30 |
31 | - [Next.js Documentation](https://nextjs.org/docs) - learn about Next.js features and API.
32 | - [Learn Next.js](https://nextjs.org/learn) - an interactive Next.js tutorial.
33 |
34 | You can check out [the Next.js GitHub repository](https://github.com/vercel/next.js/) - your feedback and contributions are welcome!
35 |
36 | ## Deploy on Vercel
37 |
38 | The easiest way to deploy your Next.js app is to use the [Vercel Platform](https://vercel.com/new?utm_medium=default-template&filter=next.js&utm_source=create-next-app&utm_campaign=create-next-app-readme) from the creators of Next.js.
39 |
