# Onchain Wallet Holder Enrichment Scraper (`jungle_synthesizer/onchain-wallet-holder-enrichment-scraper`) Actor Enrich crypto wallet addresses across 7+ EVM chains and Solana. Fetches native balance, ERC-20 holdings, transaction history, ENS name, risk flags (OFAC/Tornado Cash), DeFi positions, and social handles. Accepts a list of addresses and optional per-chain Etherscan API keys for higher rate limits. - **URL**: https://apify.com/jungle\_synthesizer/onchain-wallet-holder-enrichment-scraper.md - **Developed by:** [BowTiedRaccoon](https://apify.com/jungle_synthesizer) (community) - **Categories:** Lead generation, Developer tools - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing Pay per event This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events. Learn more: https://docs.apify.com/platform/actors/running/actors-in-store#pay-per-event ## What's an Apify Actor? Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Onchain Wallet Holder Enrichment Scraper Enrich a list of crypto wallet addresses with on-chain data across 7+ EVM chains and Solana. For each address you get native token balance, ERC-20 holdings, transaction history, ENS name, risk flags (OFAC sanctions list / Tornado Cash interactions), and social handles — all in a single structured output row per wallet per chain. ### Use Cases - **Crypto VC due diligence** — profile LP wallet histories, concentration risk, and counterparty networks before a deal - **Sales prospecting** — identify whale wallets for custody and B2B crypto services - **Compliance screening** — flag OFAC-sanctioned or Tornado Cash-linked addresses before onboarding - **Airdrop targeting** — find addresses that meet eligibility criteria (balance thresholds, protocol interactions) - **NFT / DeFi analytics** — aggregate holder enrichment for a contract's top holders ### What You Get | Field | Description | |-------|-------------| | `address` | Wallet address (checksummed EVM or Solana base58) | | `chain` | Chain queried (ethereum, bsc, polygon, arbitrum, base, avalanche, solana) | | `native_balance` | Native token balance in whole units (ETH, BNB, MATIC, etc.) | | `native_balance_usd` | Approximate USD value using live CoinGecko pricing | | `erc20_holdings` | JSON array of ERC-20 token positions: symbol, address, balance | | `first_tx_date` | Date of first transaction on this chain | | `last_tx_date` | Date of most recent transaction | | `tx_count` | Total transactions sampled (up to 200 per run) | | `unique_counterparties` | Number of unique addresses interacted with | | `total_gas_spent_usd` | Estimated total gas fees paid in USD | | `labels` | Auto-applied labels: whale, sanctioned | | `ens_name` | ENS reverse-resolved name (Ethereum only) | | `farcaster_handle` | Farcaster username if registered for this address | | `risk_flags` | OFAC-sanctioned or tornado-cash-interaction flags | | `enriched_at` | ISO 8601 timestamp when the record was produced | ### Input #### Required | Field | Description | |-------|-------------| | `walletAddresses` | One or more EVM (0x…) or Solana addresses to enrich | | `chains` | EVM chains to query per address: ethereum, bsc, polygon, arbitrum, base, avalanche | #### Optional | Field | Default | Description | |-------|---------|-------------| | `etherscanApiKey` | — | Your Etherscan API key (5 req/s with key vs. 1 req/s without) | | `bscscanApiKey` | — | BscScan API key for BSC enrichment | | `polygonscanApiKey` | — | Polygonscan API key for Polygon enrichment | | `includeErc20` | `true` | Fetch ERC-20 token balances | | `includeNfts` | `false` | Fetch NFT holdings (ERC-721/1155) | | `resolveEns` | `true` | Reverse-resolve ENS name (Ethereum only) | | `checkRiskFlags` | `true` | Check OFAC sanctions and Tornado Cash interactions | | `maxItems` | `0` (unlimited) | Cap on output records | ### Rate Limits and API Keys Without API keys the actor runs at the Etherscan free-tier rate (~1 request/second per endpoint). For high-volume enrichment (1,000+ wallets), supply your own explorer API keys — all are free to register. **To get a free Etherscan API key:** register at etherscan.io/register, then generate a key at etherscan.io/myapikey. ### Multi-Chain Output Each `walletAddresses × chains` combination produces a separate output row. Enriching 2 addresses across 3 chains yields 6 rows. Solana-format addresses are enriched on Solana automatically. ### Example Input ```json { "walletAddresses": [ "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045" ], "chains": ["ethereum"], "includeErc20": true, "resolveEns": true, "checkRiskFlags": true } ```` ### Example Output ```json { "address": "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045", "chain": "ethereum", "native_balance": 1250.34, "native_balance_usd": 4187638.20, "erc20_holdings": "[{\"symbol\":\"USDC\",\"address\":\"0xa0b86991...\",\"balance\":50000}]", "first_tx_date": "2021-01-10", "last_tx_date": "2026-05-15", "tx_count": 200, "unique_counterparties": 87, "total_gas_spent_usd": 4312.55, "labels": "[\"whale\"]", "ens_name": "vbuterin.stateofus.eth", "farcaster_handle": null, "risk_flags": null, "enriched_at": "2026-05-27T10:00:00.000Z" } ``` ### Notes - ERC-20 balances are derived from raw token transfer events. Very active wallets may show approximate values if activity exceeds the 200-transfer sample window. - USD values use CoinGecko pricing fetched at run start. - Tornado Cash and OFAC flag checks use publicly available on-chain data only. - The `airdrop_eligibility`, `defi_positions`, `nft_trading_stats`, and `dao_memberships` fields are reserved for future enrichment modules and return `null` in the current version. # Actor input Schema ## `sp_intended_usage` (type: `string`): Please describe how you plan to use the data extracted by this crawler. ## `sp_improvement_suggestions` (type: `string`): Provide any feedback or suggestions for improvements. ## `sp_contact` (type: `string`): Provide your email address so we can get in touch with you. ## `walletAddresses` (type: `array`): List of EVM or Solana wallet addresses to enrich.
