# Bridge XDN ↔ WXDN
## Bridge XDN ↔ WXDN
The [DigitalNote Bridge](https://bridge.xdn-explorer.com) converts native XDN to WXDN on your chosen chain and back, always 1:1.
> The previous bridge at wrapping.services has been retired. Bookmark **bridge.xdn-explorer.com** (wrap.digitalnote.org takes you to the same place).
### Before you start
* **XDN → WXDN:** you need XDN in a wallet you control (QT or mobile wallet recommended — not an exchange \[VERIFY: are exchange withdrawals to bridge deposit addresses supported?]).
* **WXDN → XDN:** you need a small amount of the destination chain's gas coin (BNB on BSC, ETH on Base/Arbitrum/Ethereum, POL on Polygon, SOL on Solana) and a native XDN address to receive funds.
### Wrap: XDN → WXDN
1. Open [bridge.xdn-explorer.com](https://bridge.xdn-explorer.com).
1. Select direction XDN → WXDN and choose the destination chain (only visible if > 1 chain enabled).
2. Enter the amount and your destination wallet address.
3. The bridge shows a one-time XDN deposit address. Send **exactly** the stated amount of XDN.
4. Wait for confirmations \[currently 15 XDN]. WXDN arrives at your address on the chosen chain.
> ⚠️ Deposit addresses are single-use. Never reuse one for a second transfer.
### Unwrap: WXDN → XDN
1. Open the bridge, select WXDN → XDN and the chain your WXDN is on.
2. Enter the amount and your native XDN receiving address.
3. Send WXDN to the address shown / approve the transaction in your wallet.
4. After confirmations, XDN arrives at your XDN address.
