Diamond Aggregator API Client

A TypeScript client for interacting with the Diamond Aggregator API on Solana. This client provides methods for getting quotes, creating transactions, and executing token swaps on the Solana blockchain.

Features

• Get quotes for token swaps
• Generate versioned transactions
• Execute transactions with proper signing and simulation
• Support for exact-in and exact-out swaps
• Configurable slippage tolerance
• Maximum hop limit for routing

Installation Copy

npm install @diamond-agg-sdk-test/client

Quick Start

import { clientFactory } from '@diamond-agg-sdk-test/client';

const client = clientFactory({
    rpcUrl: "YOUR_SOLANA_RPC_URL",
    apiUrl: "YOUR_CUSTOM_API_URL" // optional defaults to "https://prod.diamond-agg.api.hellomoon.io"
});

Get a quote

const quote = await client.getQuote({
    tokenIn: "TOKEN_IN_PUBKEY",
    tokenOut: "TOKEN_OUT_PUBKEY",
    action: "exactIn",
    amount: "1000000", // Amount in lamports
    slippageBps: 50, // 0.5% slippage tolerance
    userPubkey: "USER_PUBKEY",
    maxHops: 2
});

Get and execute a transaction

const txnResponse = await client.getVersionedTransaction({
    tokenIn: "TOKEN_IN_PUBKEY",
    tokenOut: "TOKEN_OUT_PUBKEY",
    action: "exactIn",
    amount: "1000000",
    slippageBps: 50,
    userPubkey: "USER_PUBKEY",
    maxHops: 2
});

const versionedTxn = client.convertTransaction(txnResponse.txn);
const signature = await client.executeTransaction({
    keyPair: yourKeyPair, // Your Solana KeyPair
    txn: versionedTxn
});
