How this service works
Wallet balances, tokens, transactions and prices on Base, Ethereum and Solana. Other Tollkit tools are described at: https://extract.tollkit.dev/openapi.json, https://attest.tollkit.dev/openapi.json, https://web.tollkit.dev/openapi.json, https://data.tollkit.dev/openapi.json.
Output
Returns a JSON object with the chain name, wallet address, a list of holdings (each with asset contract, symbol, amount, USD price sourced from on-chain pools, USD value, and any warnings), total portfolio USD value, count of unpriced holdings, timestamp of the check, and a block explorer URL for the wallet.
Example use cases
DeFi portfolio net worth check
“Can you tell me the total USD value of everything held in this Ethereum wallet: 0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045? Include USDC and USDT.”
Solana wallet token audit
“Give me a full breakdown of all tokens and their USD values in the Solana wallet 9WzDXwBbmkg8ZTbNMqUxvQRAyrZzDsGYdLVL9zYtAWWM right now.”
Automated portfolio monitoring alert
“Check the current portfolio value on Base for wallet 0x1234567890abcdef1234567890abcdef12345678 and also include the token at 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 — I want to know the total USD worth and each holding's value.”
Technical details
Endpoint
POSThttps://chain.tollkit.dev/chain/portfolio?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a comprehensive USD-denominated snapshot of all assets in a single wallet across Base, Ethereum, or Solana — especially when you want both native coin and ERC-20/SPL token values aggregated into a total. Prefer this over a simple balance check when you need portfolio-level value aggregation with real-time on-chain prices. The ability to include up to 20 extra token contracts makes it ideal for DeFi power users tracking custom tokens.
Side effects
- Invalid wallet address format returns a validation error
- Unsupported chain value outside base/ethereum/solana is rejected
- Token contract address not found on the specified chain may appear as unpriced holding
- Insufficient x402 payment (0.008 USDC) results in payment-required error
- On-chain pool data unavailable for exotic tokens results in null price and warning flag
- Rate limiting or node unavailability may cause transient 5xx errors
