Sol Hayama 🏖

sol-hayama is the decentralized NFT trading platform built on top of Solana block-chain.

• Search NFTs from a user's account(supports metaplex data structure)
• A programmatically generated escrow agent will manage the transaction and all transactions can be seen in Solana explorer

This is the frontend portion of the service. A smart contract(aka Program) that coordinates transactions is in escrow-program repo

Architecture in nutshell

Setup

yarn install

Prerequisite

Associated Token Account

• You need Associated Token Account for Native Mint to receive the fee

// Make sure the owner has enough funding
$ spl-token create-account  So11111111111111111111111111111111111111112

ProgramId for Escrow

• You also need to deploy the program on localhost's test-validator. See the instruction in the escrow-program-repo
• After you deployed the contract, you should update the programId defined in escrowProgramPublicKey which is located at constants.ts

export const escrowProgramPublicKey = new PublicKey(
  "7V3CWKtaLtYqx82Rm96ph8DutCP2LQpfkz8URpH3XAxT" // this should be your program Id
);

Amplify

• This app caches transaction data on DynamoDB for performance purposes. We use GraphQL(AppSync) from Amplify.

// use npm v14
$ npm install -g @aws-amplify/cli
$ amplify init
? Do you want to use an existing environment? Yes
? Choose the environment you would like to use: dev

Running locally

• Create .env.local (env file for nextjs) file and add below

NEXT_PUBLIC_LOCAL_ADDRESS=http://localhost:8899 // if you don't add this then the app will look into NEXT_PUBLIC_BUILD_ENV
NEXT_PUBLIC_FEE_PERCENTAGE=0.04
NEXT_PUBLIC_FEE_RECEIVER=Ae1c6oswsczoM7YtUdFLUviXMSvKgZTsZ3sJaPTyuVah // Change this to your associated account token that receives fee.
NEXT_PUBLIC_BUILD_ENV=dev

• Then start the app

npm run dev
# or
yarn dev
