How this service works
Wallet snapshot: deterministic on-chain stats for one address across major EVM chains — transaction count, token-transfer count, wallet age (first-tx date), native balance, account type, and risk-flag count. Lite-tier preview (agent-cap friendly); no investigation narrative or approval enumeration. 100% deterministic, no LLM.
Output
Returns a JSON object containing the wallet's current token balances and holdings broken down by chain, including asset types, quantities, and contract addresses for each token position found across the requested EVM-compatible networks (ethereum, base, arbitrum, optimism, polygon, gnosis by default).
Example use cases
Year-end crypto tax portfolio snapshot
“I need to pull a complete snapshot of all token balances for my wallet 0x742d35Cc6634C0532925a3b844Bc454e4438f44e across all supported chains — ethereum, base, arbitrum, optimism, polygon, and gnosis — so I can calculate my crypto gains for this tax year.”
Multi-chain DeFi portfolio audit
“Can you show me everything my wallet 0xAb5801a7D398351b8bE11C439e05C5B3259aeC9B holds on base and arbitrum right now? I want to see all token positions before I rebalance.”
Single-chain wallet holdings check
“What tokens does the wallet 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045 currently hold on ethereum only? Just ethereum, nothing else.”
Technical details
Endpoint
GEThttps://taxpulse.theaslangroupllc.com/api/crypto/wallet-snapshot?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a current multi-chain EVM wallet balance snapshot for tax reporting, portfolio auditing, or on-chain accounting purposes — especially when integrated with TaxPulse's broader tax intelligence engine for US state tax calculations. Best suited when you need holdings data across several EVM chains in a single call rather than querying each chain's RPC individually.
Side effects
- Invalid or malformed EVM address (non-0x format) returns an error
- Unsupported chain name in CSV causes that chain to be skipped or returns an error
- Empty wallet with no holdings may return empty balances object
- RPC node timeouts for specific chains may result in partial data
- Rate limiting or payment failure returns 402 or 429 status
