Install

npm install @proglet/sdk @solana/web3.js @solana/spl-token

The package is on npm as @proglet/sdk, MIT licensed. Until 1.0, a minor version may change the API, so pin the version you use.

@solana/web3.js (1.95 or newer) and @solana/spl-token (0.4 or newer) are peer dependencies, so the SDK uses the same copies as your app.

ProgletClient wraps a connection and reads accounts, quotes and builds swaps in one call each.

import { Connection, PublicKey } from "@solana/web3.js";
import { ProgletClient } from "@proglet/sdk";

const connection = new Connection("https://api.mainnet-beta.solana.com", "confirmed");
const client = new ProgletClient(connection);

const mint = new PublicKey("<coin mint>");
const pool = await client.fetchPool(mint); // null if the coin has no Proglet pool
const pools = await client.fetchAllPools(); // every pool, with its address

Everything else in the SDK is plain functions, so you can also bring your own account data, for example from the Data API.

Every builder and PDA helper takes an optional programId as its last argument, for local deployments.

The SDK and web3.js use Node's Buffer. Browsers don't have it, so install a polyfill once, before the SDK is used:

import { Buffer } from "buffer";
if (typeof globalThis.Buffer === "undefined") globalThis.Buffer = Buffer;
