Check the crypto balance of a wallet address

Provide a wallet address to request its native-asset balance and recent ERC-20 token records. Your Agent can organize the actual response with the intended chain, reported units and any available observation context.

Use blockchain-wallet-balance-strale. The user may give a wallet address or a public wallet-page link. From a link, take the wallet address only when it is clearly present in the page or URL; otherwise ask for a public page link or address. Never ask for secret recovery words or passwords. Use the network named in the task. Translate supported network names to their required values internally: Ethereum Mainnet 1, Base Mainnet 8453, Arbitrum One 42161, OP Mainnet 10, and Polygon PoS Mainnet 137. Do not ask the user for a number. Reuse Toolmu or connect via https://toolmu.com/SKILL.md. Check current availability, price, balance and authorized budget before running. Inspect the actual response or error. Keep returned amounts, units and check-time context together. Separate recent transfers from current holdings; missing data is not zero. Do not claim a complete or live portfolio.

Task:
Check [wallet address or public wallet page link] on Ethereum. If the page shows another supported network, name it: [network name]. Keep any returned balance, unit and check time together. Recent transfers may not be current holdings. Say when information is missing; do not guess or call it zero.

Check the crypto balance of a wallet address

You receive

Review any returned native balance and recent token details for the supplied address. Your Agent can keep each amount with its stated unit and chain context, while distinguishing token activity from an asset holding.

Start with your task

Check [wallet address or public wallet page link] on Ethereum. If the page shows another supported network, name it: [network name]. Keep any returned balance, unit and check time together. Recent transfers may not be current holdings. Say when information is missing; do not guess or call it zero.

What to know

Recent token records do not establish a complete portfolio or current token holdings. Check the response for units and any time or block context; do not assume a live balance or turn missing information into zero.

Field / Path	Type	Requirement	Meaning
queryParams`queryParams`	`object`	Required	Required fields `address`
Wallet address`queryParams.address`	`string`	Required	Required address string, described as a wallet address beginning with 0x. Preserve the address you intend to check. No format, checksum or normalization rule is declared.
Chain ID`queryParams.chain_id`	`string`	Optional	Optional chain-ID string. Its description identifies 1 as Ethereum and describes the default as 1; the schema does not set a default or enumerate supported chains. Keep the intended network with the result.

Additional notes

The Strale capability description declares a wallet's native balance and the ERC-20 tokens it most recently sent or received as this lookup's purpose. The named networks describe supplier coverage; inspect the actual response for your requested address and chain.

If the response supplies units, token identifiers or time/block context, retain them with the related amount or record. Preserve the reported precision rather than guessing decimal scaling or converting an amount to a currency value.

A recent token record is activity context, not proof of a current holding. Your Agent can present that context separately from the native balance and mark missing values clearly; an incomplete response should not be treated as an empty wallet.
