| 34 | - Fake account that cannot be linked to you |
| 35 | - Build a posting history (post stuff, etc.) |
| 36 | - Resources |

| 39 | - [Fake Name Generator](https://www.fakenamegenerator.com/) |
| 40 | - [This Person does not Exist](https://thispersondoesnotexist.com/) |
| 41 | - Use separate browser profiles or isolation tools (e.g., **Firefox Multi‑Account Containers**) for any sock‑puppet activity. |
| 42 | - Acquire disposable VoIP/SMS numbers (e.g., **Burner**, **Silent Link**) to satisfy platform verification without exposing real phone numbers. |
| 43 | - Audit every browser extension before installation; supply‑chain attacks on popular add‑ons have targeted investigators since 2024. |
| 44 | - Use dedicated browser profiles/containers per case and persona; avoid logging into personal accounts. |
| 45 | - Prefer hardware‑backed passkeys for critical accounts; store recovery codes offline. |
| 46 | - Maintain a minimal chain‑of‑custody: timestamp actions, hash key artifacts, and record tool versions per case. |

| 50 | ### Transaction Analysis |
| 51 | |
| 52 | - Track transaction flows between wallets |
| 53 | - Identify clusters of related addresses |
| 54 | - Monitor large transfers and whale activity |
| 55 | - Use block explorers to trace fund movements |
| 56 | - Tools: |
| 57 | - Cielo: Multi-chain wallet tracking (EVM, Bitcoin, Solana, Tron) |
| 58 | - TRM: Create relationship graphs for addresses/transactions |
| 59 | - Arkham: Multichain explorer with entity labels, graph creation, and alerts |
| 60 | - MetaSleuth: Transaction visualization for retail users |
| 61 | - Range: CCTP bridge explorer |
| 62 | - Socketscan: EVM bridge explorer |
| 63 | - Pulsy: Bridge explorer aggregator |
| 64 | - Chainalysis: **Horizon 2.0** cross‑chain tracing suite (paid) |
| 65 | - Elliptic: **Lens** visual link explorer (launched Dec 2024) |
| 66 | - Most compliance suites now provide **real‑time bridge‑risk scoring** dashboards (e.g., TRM, Chainalysis) |
| 67 | |
| 68 | #### Layer 2 / Rollup Analysis |
| 69 | |
| 70 | - **zkSync Era / Polygon zkEVM**: Zero-knowledge proofs hide transaction details on L2; only deposit/withdrawal bridge events visible on L1. Use [zkSync Era Block Explorer](https://explorer.zksync.io/) and [PolygonScan zkEVM](https://zkevm.polygonscan.com/). |
| 71 | - **Arbitrum / Optimism**: Transactions batched and compressed; L2 state reconstructed from L1 calldata. Use [Arbiscan](https://arbiscan.io/) and [Optimistic Etherscan](https://optimistic.etherscan.io/). Check [L2Beat](https://l2beat.com/) for risk framework and technology stack. |
| 72 | - **StarkNet**: Cairo VM with STARK proofs; different address derivation. Use [Voyager](https://voyager.online/) or [StarkScan](https://starkscan.co/). |
| 73 | - **Base / Blast / Scroll**: OP Stack or ZK-rollups; similar challenges to above. |
| 74 | - **Privacy protocols on L2**: |
| 75 | - Aztec Network: Programmable privacy with noir circuits; limited block explorer visibility. |
| 76 | - Railgun: Privacy system for DeFi on Ethereum/Polygon/BSC; shielded pools obscure sender/receiver/amount. |
| 77 | - Privacy Pools: Proposed Tornado Cash successor with association sets; not yet deployed at scale. |
| 78 | - **Challenges**: |
| 79 | - Bridge mixers (Hop Protocol, Across, Stargate) create synthetic liquidity pools that break direct tracing; funds enter/exit via pool swaps. |
| 80 | - Cross-rollup transfers further obfuscate trails; requires tracking via bridge contracts and relayer infrastructure. |
| 81 | - Many L2s lack mature analytics tools; explorers show transactions but relationship graphs are sparse. |
| 82 | - **Methodology**: |
| 83 | - Start with L1 bridge events (deposits/withdrawals); these anchor L2 activity to known addresses. |
| 84 | - Use L2-specific explorers to trace activity within the rollup. |
| 85 | - For privacy protocols, focus on timing analysi |
