Simple NFT Marketplace

日本語の解説ブログはこちら

This project provides sample code to build a simple NFT (Non-Fungible Token) based marketplace with Amazon Managed Blockchain.

NFTs are cryptoassets in which each token is unique, and therefore able to create a relationship, or contract, between a specific unique token, and a specific asset - including physical asset, virtual asset and more. This contract allows ownership of a digital asset to be proven. For this reason, NFTs are also known as deeds.

While there are multiple standards for non-fungible tokens, this exercise will use the Ethereum Blockchain network, and ERC721 standard for non-fungible tokens.

To be able to create the required contracts, we will:

Create a Node connected to a Blockchain network
Manually Generate, verify and deploy a contract.
Deploy an API to automate the process
Create a Front End that utilizes the API
Deploy the MarketPlace Front End

You will use the following tool set:

Git, and your OS Command Line
Node.js and npm
the AWS CLI and AWS Console
AWS CDK to deploy backend API (/provision)
Contract written in Solidity (/contract)
Marketplace web UI (/marketplace)

Do NOT use this codes in your production workloads.

Add automation to steps

The step-by-step instructions are great for users who want to learn but some users may also find an automated setup/deploy convenient as well.

Upgrade to Goerli

Since Ropsten has been deprecated, we should update the documentation and any related code to reference Goerli instead.

Note: Sepolia is not an option for AMB at the time of writing.

Handling of private keys

consider use Parameter Store - Secrets Manager or KMS to store the private keys

Migrate to CDK 2.x

Insufficient funds

I followed the full documentation and after the stack deployed I saw
Checking ETH balance for address 0x083bF8ec0bA1d508b03E1815870968F98A32114e
ETH balance for 0x083bF8ec0bA1d508xyzE1815870968F98A32114e is 0. Sleeping for 5 seconds before checking again

ETH balance for 0x083bF8ec0bA1d508xyzE1815870968F98A32114e is 0. Sleeping for 5 seconds before checking again

I made the decision to do it manually but I have this issue
npx hardhat run --network amb scripts/deploy-amb.js

issue regarding no show for account details

I followed all your steps but while coming to the next step after creating account my account details are not showing c=giving 502 error neither gives option to connect with metamask

Prepare English docs

Currently only Japanese docs are prepared.

Create blockchain node with CDK

Failed to load resource: the server responded with a status of 502 ()

Everything in the app is working beside the following:

The problem arises in the Eth Deposit section of Docs: https://github.com/aws-samples/simple-nft-marketplace/blob/main/docs/en/DOCS_04_FRONTEND.md

After I click the "Account" button in the upper right-hand corner of the page I do not see the following information:
Address: Public Address
Balance: The balance of deposited Ethereum
Private Key: The private key of the wallet. Display by pressing the "Retrieve" button

Rather, I see "Loading ..." see below:

In the console I get the following error:

Failed to load resource: the server responded with a status of 502 ()
vue.runtime.esm.js:3019 Error: Request failed with status code 502
    at e.exports (createError.js:16:15)
    at e.exports (settle.js:17:12)
    at XMLHttpRequest.S (xhr.js:66:7)

Im not sure if its an error in the front end, env variables, or one of my AWS apps. Please help as I am very excited about this repo and already learned a ton!
