How this service works
Who is this Arbitrum One address? Wallet age (first transfer), first funder, contract or EOA, ETH balance and nonce, the latest transfers in and out (native, ERC-20, NFTs), top counterparties by count, and recent large transfers in USD (ETH, WETH, USDC, USDT), from Alchemy's transfer index.
Output
Returns a JSON object containing: wallet age in days and first activity timestamp/tx, account type (EOA or contract), nonce, native ETH balance with USD value, first funder address/amount/tx, activity breakdown by category (external/ERC-20/ERC-721/ERC-1155), recent inbound and outbound transfers with asset, amount, USD value, counterparty, and block, large USD transfers list, and the ETH/USD price sourced from Chainlink.
Example use cases
Vetting a new DeFi counterparty
“Before I send funds to 0xAbCd1234...on Arbitrum, can you check how old that wallet is, who originally funded it, whether it's a contract or a regular wallet, and what its recent transfer activity looks like?”
Onboarding KYC-lite for Web3 app
“A user just signed up with 0x1234abcd...as their Arbitrum address — can you tell me when that wallet was first active, its current ETH balance, and who the top counterparties are so I can assess their account history?”
Investigating a suspicious airdrop recipient
“We're seeing large outflows from 0xDeadBeef...on Arbitrum — can you show me when the wallet was created, who funded it, its nonce, and any recent large transfers in USD so I can figure out if it's a bot or airdrop farmer?”
Technical details
Endpoint
GEThttps://onchaincheck.dev/arbitrum/wallet-profile?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive wallet intelligence snapshot for an Arbitrum One address — combining age, funding origin, balance, nonce, and transfer history in a single call. Prefer over raw RPC calls when you need enriched, human-readable data including USD values and counterparty analysis. Choose over generic blockchain explorers when you need structured JSON output suitable for agent pipelines. Best when analyzing wallet provenance, vetting counterparties, or building onchain identity signals specifically on Arbitrum One (not Ethereum mainnet, Base, OP Mainnet, or Solana).
Side effects
- Invalid address format (not a valid 0x hex address) — returns validation error
- Address not found on Arbitrum One — may return empty/zero profile
- Alchemy transfer index unavailable — upstream dependency failure
- Only the newest 100 inbound and 100 outbound transfers are scanned; older history is not included
- Zero-value transfers are excluded from activity counts
- Network timeout or rate limit from underlying Alchemy API
