# WXDN Security & Transparency

## WXDN: Security & Transparency

WXDN (Wrapped DigitalNote) is designed to be a transparent, 1:1 wrapped representation of XDN. This page summarises how the token contracts are built and what protections are in place. Always cross-check the official contract addresses on \[Supported Chains & Contract Addresses].

### How WXDN is backed

Every WXDN is redeemable 1:1 for native XDN through the [DigitalNote Bridge](https://bridge.xdn-explorer.com). WXDN is not a separate coin — it is XDN represented on another chain, and wrapping/unwrapping does not change the total XDN supply.

### EVM chains (Ethereum, Base, Polygon, Arbitrum)

The WXDN contract is a standard **ERC-20** token built on the widely-used, audited OpenZeppelin v5 libraries, with **18 decimals**. Its source code is **publicly verified** on each chain's block explorer, so anyone can read exactly how it works:

* [Ethereum (Etherscan)](https://etherscan.io/token/0x75B999F3Df6100A47De7581626c022CBe173a548)
* [Base (BaseScan)](https://basescan.org/token/0x75B999F3Df6100A47De7581626c022CBe173a548)
* [Polygon (PolygonScan)](https://polygonscan.com/token/0x75B999F3Df6100A47De7581626c022CBe173a548)
* [Arbitrum (Arbiscan)](https://arbiscan.io/token/0x75B999F3Df6100A47De7581626c022CBe173a548)

What this means for holders:

* **No per-holder freeze.** The contract has no ability to freeze or seize an individual holder's balance.
* **Standard, predictable behaviour.** Transfers, approvals and balances follow normal ERC-20 rules, so WXDN works with MetaMask and any standard wallet or DEX.
* **You can burn your own tokens**, and the contract supports gasless approvals (EIP-2612 "permit") for smoother interactions with apps that use it.
* **Emergency safeguard.** Like many tokens, transfers can be paused in an emergency; under normal operation the token is fully transferable.

Before launch, the contract was reviewed and run through an extensive behavioural test suite covering transfers, approvals, burning, ownership handling and edge cases, with no issues identified.

### Solana

On Solana, WXDN is an **SPL Token-2022** mint with **9 decimals** (the standard Solana convention; it does not affect redemption value). Its metadata (name, symbol, logo) is stored on-chain.

The most important holder protection on Solana:

* **Freeze authority is permanently disabled.** No authority can ever freeze or lock your WXDN account — this is a one-way, irreversible setting on the mint.

You can verify the Solana token here: [Solscan](https://solscan.io/token/67uww5rWac4Du7n6oVEjoAEvJwC6RUdeWkBHE1UrYKEs).

### Verify it yourself

You never have to take our word for any of this. Open the explorer links above, confirm the contract address matches [\[Supported Chains & Contract Addresses\]](/supported-chains.md), and read the verified source directly.
