In the fast-evolving world of Web3, access to accurate, real-time blockchain data is essential for developers, analysts, and decentralized application (dApp) creators. One of the most powerful tools in this ecosystem is address-based asset inquiry—a method that enables users to retrieve detailed financial and transactional insights tied to a specific blockchain address.
This guide dives deep into how modern Wallet APIs, particularly those offered by platforms like OKX Web3, empower developers to extract granular asset information from blockchain addresses. Whether you're building a portfolio tracker, conducting on-chain analysis, or integrating wallet functionality into your dApp, understanding address-level data retrieval is crucial.
Understanding Address-Based Asset Inquiry
At its core, address-based asset inquiry refers to the process of querying all digital assets held by a given blockchain address. Unlike account-based systems in traditional finance, blockchain wallets are often pseudonymous and non-custodial, meaning ownership and balance data must be fetched directly from the chain.
With the right API infrastructure, developers can:
- Retrieve total asset valuations
- List all token balances (fungible and non-fungible)
- Check UTXO (Unspent Transaction Output) holdings
- Explore NFTs and inscriptions
- Monitor smart contract approvals
These capabilities form the backbone of many Web3 applications—from DeFi dashboards to NFT marketplaces.

Key Features of Address Dimension Asset Queries
Modern Wallet APIs support a wide range of endpoints under the umbrella of address-based inquiries. Below are the primary functionalities available today.
1. Total Asset Valuation
Get an aggregated view of an address’s total net worth across supported chains. This includes:
- Native coins (e.g., ETH, BTC, SOL)
- ERC-20 and BEP-20 tokens
- NFT floor price estimates
- Staked or locked assets (where detectable)
The valuation is typically returned in USD or another fiat equivalent, updated using real-time market pricing.
2. Detailed Token Balances
Retrieve a complete list of all fungible tokens held by an address. The response includes:
- Token symbol and name
- Contract address
- Decimal precision
- Raw balance and formatted amount
This endpoint supports multi-chain environments, making it ideal for cross-chain portfolio trackers.
3. Query Specific Token Balance
Instead of fetching all tokens, developers can directly query the balance of a single known token (e.g., USDT on Ethereum). This reduces response size and improves performance when checking for specific holdings.
4. UTXO Management for Bitcoin-Like Chains
For blockchains based on the UTXO model (such as Bitcoin), the API allows retrieval of:
- All unspent outputs
- Output value and script details
- Confirmation status
This is especially useful for wallet builders and payment processors needing precise control over transaction inputs.
5. Inscription Data on UTXOs
With the rise of Bitcoin inscriptions like Ordinals and Runes, it's now possible to query not just coin value but also embedded digital artifacts on individual UTXOs. Developers can:
- Identify whether a UTXO contains an inscription
- Retrieve inscription ID, type (text, image, etc.), and content preview
- Track rarity or provenance metadata
This feature bridges traditional Bitcoin analysis with emerging digital collectible use cases.
6. Smart Contract Approval Tracking
One of the most critical security features: approval inspection. Users often grant spending permissions to dApps via ERC-20 approve() functions. Mismanaged approvals pose significant risks.
An advanced Wallet API lets you:
- List all active token approvals for an address
- Identify spender contracts (e.g., DEXs, lending protocols)
- View approved amounts and detect unlimited allowances
- Recommend revocation if needed
This functionality enhances user transparency and security monitoring.
Why Use a Wallet API for On-Chain Data?
While raw blockchain data is public, extracting meaningful insights requires substantial technical overhead—running nodes, parsing transactions, managing state diffs, and normalizing cross-chain formats.
A robust Wallet API abstracts this complexity by offering:
- Unified RESTful interfaces across multiple blockchains
- High availability and low-latency responses
- Normalized data structures (no more handling different token standards manually)
- Built-in rate limiting, caching, and error handling
Developers save months of backend development while ensuring accuracy and scalability.

Frequently Asked Questions (FAQ)
Q: Can I query assets across multiple blockchains at once?
A: Yes. Modern Wallet APIs support cross-chain queries, allowing you to fetch balances from Ethereum, BSC, Solana, Bitcoin, and more using a single address input.
Q: Is personal user data required to perform these queries?
A: No. All queries are based on public blockchain data. You only need the wallet address—no private keys or personal identification is involved.
Q: How frequently is the asset data updated?
A: Most APIs provide near real-time updates with polling intervals as low as a few seconds. Some even offer webhook notifications for balance changes.
Q: Can I use this to detect phishing risks or malicious approvals?
A: Absolutely. By analyzing unusual approval patterns (like unlimited allowances to unknown contracts), your app can warn users before they interact with risky dApps.
Q: Are NFTs included in asset inquiries?
A: Yes. The asset details endpoint typically includes both fungible tokens and NFTs, with metadata such as collection name, token ID, and image URL where available.
Q: Does this work for contract wallets or ENS names?
A: Many APIs resolve ENS and other decentralized identifiers automatically. For smart contract wallets (e.g., Argent, Safe), balance queries still work as long as the contract follows standard interfaces.
Use Cases in Real-World Applications
Portfolio Trackers
Aggregating holdings across chains and displaying them in a clean UI relies heavily on accurate address-based balance fetching.
Security Audits
dApps can scan user wallets for risky permissions and suggest revocations—enhancing trust and safety.
NFT Marketplaces
Displaying a user’s full NFT inventory—including rare inscriptions—improves browsing and trading experiences.
DeFi Analytics Platforms
Analyzing borrowing capacity, collateral positions, or yield farming exposure starts with comprehensive asset discovery.
KYC/Compliance Tools
While preserving privacy, institutions can verify asset declarations against on-chain reality during due diligence processes.
Getting Started with Web3 Integration
To begin leveraging address-based asset queries:
- Choose a reliable Wallet API provider with broad chain support.
- Obtain an API key (often free for development tiers).
- Start testing endpoints like “Get All Token Balances” or “Total Asset Value.”
- Integrate responses into your frontend or backend logic.
- Add caching and error fallbacks for production readiness.
Documentation should include clear examples in popular languages (JavaScript, Python, etc.) and support for both mainnet and testnet environments.
Final Thoughts
As Web3 adoption grows, so does the demand for intuitive, secure, and scalable tools to interpret on-chain data. Address-based asset inquiry stands at the forefront of this evolution—enabling developers to build richer, smarter applications without reinventing the wheel.
From tracking simple token balances to uncovering hidden inscriptions on Bitcoin UTXOs, the depth of insight available today is unprecedented. With powerful APIs handling the heavy lifting, innovation moves faster than ever.
