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
yarn install
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
escrowProgramPublicKeywhich 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
