Privacy practices for DCR trades

Decred (DCR) launched in 2016 as a hybrid Proof-of-Work + Proof-of-Stake cryptocurrency with on-chain governance. Every block is mined by PoW miners AND voted on by 5 PoS ticket-holders chosen pseudo-randomly from the staking pool — neither group can change the protocol rules unilaterally. On-chain governance via Politeia lets stakeholders propose, debate, and ratify protocol changes; treasury funds (10% of block reward) flow through community vote. The chain is transparent at the base layer — sender, recipient, and amount are visible on chain like Bitcoin. Decred ships an opt-in CoinShuffle++ (CSPP) mixing protocol integrated into dcrwallet: users can enable mixing in their wallet to break the on-chain transaction graph between deposit and withdrawal, similar in posture to Bitcoin coinjoin or Dash PrivateSend. The practices below cover wallet-side hygiene to make the most of Decred's privacy features.

Use a fresh address every trade

This chain uses transparent addresses with no native stealth. The standard practice: use a Hierarchical Deterministic (BIP-32) wallet that derives a new receive address per request. Most modern wallets do this automatically. The cost of address reuse is severe — every trade you accept at the same address builds a public record of your activity.

Opt-in privacy technologies

Standards that wallets in this ecosystem may implement. Vigilante Trading does NOT recommend specific wallet software — even reputable wallets have been compromised. Search for a wallet that supports these standards and review its trust posture yourself.

  • CoinShuffle++ (CSPP) mixing

    A wallet-side mixing protocol that bundles your transaction inputs with other participants in a single multi-party round. After mixing, your outputs are no longer linkable to your original inputs on chain. Integrated into dcrwallet for Decred — enable the "Mix Account" option. Opt-in (you choose when to mix); off-protocol (mixing rounds aren't enforced by consensus).

Universal practices

**Use a fresh receive address for every trade.** Your wallet should support this; if it doesn't, look for one that does. Address reuse is the single biggest leak.

**Practice coin control when spending.** When sending coins later, avoid combining the trade output with coins from another source — that combines their address histories permanently.

**Broadcast through Tor or your wallet's privacy mode.** Your home IP address sees the transaction first; nodes near your IP can correlate it to you. A Tor-aware wallet broadcasts through Tor by default.

**Avoid sending trade coins to or from KYC exchanges.** Once trade coins touch a KYC exchange, the trade becomes legally identifiable by combining exchange records with chain data. If you need to bridge to fiat, route through a self-custodied intermediate step.

What to avoid

  • Do not paste your same receive address into multiple trades.
  • Do not send the exact amount listed on the order — Vigilante Trading's amount-randomizer toggle (the "🔐 Randomize amount" checkbox in the address-share modal) breaks this; leave it ON.
  • Do not combine the trade output with coins from a different source when you later spend it.
  • Do not broadcast from your home IP via a non-private wallet — use Tor.

⚠ Caveats specific to this asset

Decred is transparent at the base layer; mixing is opt-in and wallet-side. - **Share fresh addresses per trade.** Using the same `Ds` or `Dc` address across multiple Vigilante Trading listings lets observers correlate your orders on a fully transparent chain. Generate a fresh receive address per trade (Decred wallets derive these from your HD seed). - **Use CSPP mixing if you want transaction-level privacy.** In dcrwallet enable the "Mix Account" option; deposits flow through CoinShuffle++ rounds with other participants before becoming spendable from your mixed account. Mixing rounds happen approximately every 20 minutes on mainnet. - **Wallet compatibility.** The official wallets are dcrwallet (CLI/headless), Decrediton (GUI), and Cake Wallet (mobile, DCR mode). Some other wallets support DCR send/receive but not CSPP mixing. - **Network-layer privacy still matters.** Broadcasting through Tor or your wallet's privacy mode keeps your home IP off the chain's view of you. - **Politeia treasury proposals are public.** Decred's on-chain governance system shows every proposal, vote, and discussion publicly. This doesn't affect trading on Vigilante Trading, but it's worth knowing if you participate in DCR governance.

Vigilante Trading does NOT recommend specific wallet software. Even reputable wallets have been compromised or have had hidden flaws. The privacy techniques here are protocol standards, not endorsements — your wallet, your responsibility.
