Wallet Sync and the Privacy of Swap Addresses

Your wallet app can reveal activity off-chain

A blockchain explorer shows public transaction details, but your wallet activity may also be visible to a service provider. Depending on the wallet and its settings, the app may send address queries or wallet data to display balances and transactions. Some wallets also offer account sync, backups, or shared portfolios.

A wallet provider may be able to associate addresses with an app session or account, even when those details are not published under your name on-chain. Data practices vary by wallet, so check the provider’s documentation and settings.

Check before receiving swap output

Before placing an order, decide which wallet will receive the output and review how it handles data:

• Check whether the wallet uses an account, cloud backup, or synced portfolio features.
• Look for privacy or network settings that control address queries and telemetry.
• Avoid putting sensitive labels in shared or synced wallet views. A label may be private in one app and synced in another.
• Keep your recovery phrase and private keys out of websites and support chats. ShadowSwap never asks for private keys.

ShadowSwap requires no account, KYC, name, email, or identity document. It stores order data—including amounts, addresses, transaction hashes, and the IP address used to place the order—to process and protect swaps. For each order, ShadowSwap generates a one-time deposit address it controls, holds the deposit while processing the swap, and sends the output directly to the wallet address you provide. Read how ShadowSwap works before choosing your receiving wallet.

After the output arrives

Wallet-provider visibility and on-chain visibility are separate. A provider may see wallet queries, while a transaction can reveal public blockchain information such as amounts and address relationships. Wallet settings can reduce some off-chain exposure, but they cannot erase information already recorded on a public blockchain.
