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

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) |

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.

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, anddao_membershipsfields are reserved for future enrichment modules and returnnullin the current version.
