Getting started
- Create a typescript project:
mkdir dexterity-project
cd dexterity-project
npm i typescript --save-dev
npx tsc --init
- Install Dependencies:
npm install @solana/web3.js @pepperdex/dexterity-ts @coral-xyz/anchor
- Create a Solana Wallet and export your private/secret-key:
- Send yourself some devnet SOL:
- Send yourself some devnet UXDC:
Index
- Create TRG, Get TRGs, Deposit, Withdraw, Place Order
- Get all MPGs and their Products for each
- Fetch, parse & stream Orderbook
- Mark & Index Price
- Account info
- Instructions Bundle
