Use when auditing whether reusing the same address across chains such as Ethereum, Arbitrum, Solana and Bitcoin lets an observer link a desk's activity, scoring the deanonymisation exposure of a wallet registry you supply.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
## When to Use Use this skill in institutional crypto trading desks and automated bot architectures to audit wallet address reuse across multiple blockchain networks (Ethereum, Arbitrum, Solana, Bitcoin). Using identical public key addresses or static EVM `0x...` addresses across multiple chains enables on-chain analytics firms (Chainalysis, Elliptic, Nansen) to deanonymize proprietary trading strategies, track total fund AUM, and link private wallets to KYC exchange deposits. This module computes an Address Reuse Privacy Risk Score and recommends HD Wallet BIP-44 path isolation. ## When NOT to Use - **As an on-chain scanner.** `CrossChainAddressPrivacyAuditor` reads only the registry you hand it via `register_wallet()`. It opens no RPC connection, queries no explorer and imports nothing outside the standard library, so an address the desk never registered is invisible to it and scores as no risk. Completeness of the registry is a precondition, not an output — reconcile it against the chains before trusting a low score. - **As transaction or counterparty screening.** The score measures *your* deanonymisation …

How to install
mdr add himanshuj16/algo-trading-skills/cross-chain-address-reuse-privacy-risk@sha256:c4c7306b6d5f1764The line at the top of this page pins the label v1.2.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
