WindStack SDK

WindStack is a general-purpose, ESM-first TypeScript SDK for Antelope chains, Vexanium, EVM providers, Solana providers, signing requests, exact asset arithmetic, and reusable protocol math.

Overview

Packages are independently installable and tree-shakeable. Generic primitives do not depend on a particular wallet, explorer, bot, DEX, token registry, or application state.

Package	Purpose
@windstack/core	Provider errors/events, exact decimals, basis points, constant-product quotes, routes, and liquidity math
@windstack/crypto	K1/R1 keys and canonical signatures, WIF, recovery, and VEX/EOS/PUB_K1 compatibility
@windstack/abi	Antelope ABI/binary codec, names, exact assets, extended assets, token identity, and precision conversion
@windstack/rpc	Typed Antelope RPC, verified endpoint failover, Spring finality, and Hyperion history
@windstack/contract	ABI caching, contract actions, and table queries
@windstack/account	Generic Antelope token, resource, governance, account, and permission actions
@windstack/antelope	TAPOS, transaction serialization/digest/id, signers, required keys, broadcast, and keosd
@windstack/signing-request	Portable ESR/VSR actions, transactions, identity requests, callbacks, compression, and resolution
@windstack/session	Runtime-neutral Antelope signer/session and wallet-plugin orchestration
@windstack/evm	Addresses, chain IDs, verified JSON-RPC, EIP-1193 clients, and EIP-6963 discovery
@windstack/solana	Solana provider discovery and account/client utilities
@windstack/vexanium	Vexanium presets, VEX EVM bridge and contract-action decoding, provider protocol, and explorer routes
@windstack/wallet-plugin-wisp	Optional Wisp Wallet adapter for the generic session API

Installation

Install only the packages needed by an application:

npm install @windstack/antelope @windstack/rpc
npm install @windstack/core @windstack/evm
npm install @windstack/vexanium

Usage

Exact values and protocol math never require floating point:

import {
  parseDecimal,
  quoteConstantProduct,
  quoteConstantProductMinimum,
} from "@windstack/core";

const amountIn = parseDecimal("10.0000", 4);
const quote = quoteConstantProduct({
  reserveIn: 1_000_000n,
  reserveOut: 2_000_000n,
  amountIn,
  feeBps: 30,
});
const minimum = quoteConstantProductMinimum(quote, 50);

Build and sign an Antelope transaction with a network-specific client:

import { PrivateKey } from "@windstack/antelope";
import {
  createVexaniumAntelopeClient,
  createVexaniumPrivateKeySigner,
} from "@windstack/vexanium/antelope";

const client = createVexaniumAntelopeClient();
const signer = createVexaniumPrivateKeySigner([
  PrivateKey.fromString("PVT_K1_..."),
]);

const transfer = await client
  .account("alice")
  .transfer("bob", "1.0000 VEX", "example");

await client.transact({ actions: [transfer], signer });

The Vexanium signer announces legacy K1 keys with the native VEX prefix. The parser and required-key flow treat equivalent VEX…, EOS…, and PUB_K1_… strings as the same key.

Vexanium Mainnet

Setting	Value
Chain ID	f9f432b1851b5c179d2091a96f593aaed50ec7466b74f89301f957a83e56ce1f
RPC	https://api.windcrypto.com
System contract	vexcore
Native token contract	vex.token
Native symbol and precision	VEX, 4
VEX EVM chain ID	6736 (0x1a50)

Vexanium-specific presets and the reserved 0xbbbb… native bridge address format live in @windstack/vexanium; generic EVM behavior remains in @windstack/evm.

Runtime

Node.js 20.19, 22, and 24 are covered by CI. Browser-safe entrypoints use Web APIs and do not import Node built-ins. Unix-socket keosd support is isolated behind @windstack/antelope/node.

Reliability

Read failover verifies every endpoint against the configured chain ID before use. Broadcast calls never retry automatically. RPC payloads, required keys, signatures, large integers, checksums, bridge calldata, and finality states are validated before acceptance. All public packages ship ESM, source maps, and declaration files.
