# WDK Utils

WDK Utils provides validation helpers for Bitcoin, EVM, Lightning, Spark, Tron, and UMA identifiers, Lightning decoding helpers, plus EIP-681 request parsing helpers for token transfer deep links. Powered by [`@tetherto/wdk-utils`](https://github.com/tetherto/wdk-utils).

## Features

* **Address validation helpers**: Validate Bitcoin, EVM, Lightning invoice, LNURL, Lightning address, Spark, Tron, and UMA inputs before you hand them to a wallet flow.
* **Lightning decoding helpers**: Decode BOLT11 invoices and LNURL strings before you display or route payment details.
* **EIP-681 request parsing**: Detect request-shaped EIP-681 strings and parse transfer payloads into `recipient`, `tokenAddress`, `chainId`, and `amountSmallest`.
* **No runtime setup**: Import the functions you need. The package has no constructor or runtime configuration.
* **TypeScript support**: The published package ships typed exports for every validator and parser.
* **Bare runtime export**: The package publishes a bare entrypoint in addition to the default module entrypoint.

## Why this matters

* Validate user input early and return machine-readable failure reasons before you attempt a transaction or resolution flow.
* Normalize EIP-681 payment links into structured transfer data that wallet UIs can inspect before execution.
* Reuse the same helpers across Node.js and Bare-based environments without adding a larger wallet module dependency.
