Functionalities like APIs, which are not easily noticeable to daily users when using products, are like the "invisible infrastructure" of the OKX Web3 wallet. Despite their importance, they are rarely widely known by users. As there is currently no introduction to OKX Web3 wallet APIs available on the market, this article will focus on the API aspect, comprehensively analyzing the functions of OKX Web3 API, with the hope of attracting and assisting more developers in realizing their ideas and innovations.
This is the content of the first phase of OKX Web3's invisible infrastructure, as well as the first phase of OKX Web3 API series. The second phase will delve into the stories behind the construction of APIs by the OKX Web3 team through dialogue.
OKX Web3 Wallet API Framework
API, short for Application Programming Interface, is a set of definitions and protocols used to build and integrate application software. APIs allow communication and data exchange between different software systems. Through APIs, developers can utilize existing functions and data without having to write code from scratch. APIs can significantly improve development efficiency, promote system interoperability, and drive technological innovation.
As a leading one-stop Web3 gateway, OKX Web3 provides a complete Web3 development solution—OnchainOS. As a multi-chain Web3 development engine, OnchainOS has standardized access to chains and services, greatly reducing development cycles and costs, including wallets, DEX aggregators, Marketplaces, DeFi, and other major modules, as well as on-chain data solutions for trading liquidity. If developers wish to build their own Web3 services, using OnchainOS will be a more efficient and economical choice.
In order to better serve developers, greatly reduce the development threshold, and improve efficiency, OKX Web3 provides a very comprehensive, detailed, and visually combined API documentation. Interested developers can click to view it at any time and follow the steps to use it.
The OKX Web3 wallet now supports over 100+ public chains and provides a unified user experience across three platforms: App, plugin, and web, covering five major sections including wallets, DEX aggregators, DeFi, NFT markets, and DApp exploration. It has also launched the Bitcoin Inscription and Rune trading markets, dedicated to providing comprehensive Web3 services to users.
Next, the article will use the wallet, DEX aggregator, Marketplace, and DeFi sections as examples to introduce some API-related content.
Wallet API
As the core of the entire product, the wallet section's API provides the underlying technical solutions for non-custodial wallets, which can help developers easily build on-chain services and applications. For example, Web3 multi-chain wallets, DApp built-in wallets, multi-chain Web3 applications, and exchange wallet services, etc.
The wallet API has three core functions in wallet services: 1) Multi-chain address aggregation, providing the capability to aggregate assets of millions of addresses; 2) Multi-scenario, easy access to 60+ networks, supporting heterogeneous multi-chain ecosystems and various BTC asset protocols; 3) High availability and stability. Implementing interface and system monitoring to ensure smooth access.
By using the wallet API, developers can efficiently and securely build wallets in just 3 steps, easily access 60+ networks, including popular EVM, Solana, TRON, BTC, etc., and also support cutting-edge ecosystems such as Inscription. Subsequent wallet APIs will gradually provide the capabilities and solutions for MPC wallets and AA smart wallet accounts. Through powerful wallet services, developers' Web3 wallet development needs can be fully met, and the entry process for Web3 wallets can be simplified.
Specifically, the wallet API covers multiple core modules, meeting users' basic asset management and transaction needs. For example: address and wallet generation, on-chain asset and coin price information query, transaction management, as well as currency information, Gas prices, and address authorization information, and other commonly used data queries. Among them, the transaction management module provides very rich services such as building, signing, broadcasting, tracking transaction history, supporting transactions on EVM and UTXO model networks such as BTC, etc. Overall, developers can use the wallet API for account management, asset management, transaction management, common information queries, and Webhook (real-time subscription to on-chain data), etc.
First, in terms of account management. Different from the general single address query mode, the wallet API provides structured subscription queries for multiple addresses, allowing developers to associate multiple addresses with one account, efficiently query asset status and transaction history in multi-chain scenarios. The wallet API provides two types of accounts: wallet accounts and observation accounts. Among them, 1) Wallet accounts require message signatures for authentication, can freely add custom tokens, and can send transactions. 2) Observation accounts do not require message signatures, and by default display all tokens included in the OKX platform, and cannot send transactions.
Developers can use the account management API to create wallet accounts and manage addresses under wallet accounts, aggregate observation account addresses, update wallet accounts, update observation accounts, delete accounts, query created account lists, query addresses under accounts, etc.
Second, in terms of asset management. This includes adding subscribed currencies to accounts, obtaining corresponding asset balances, viewing total assets, and deleting assets that are no longer of interest. It is worth noting that for wallet accounts, developers can add and manage custom currencies. For observation accounts, custom addition or management is not possible, and only the asset balances of currencies supported by the current wallet API can be obtained.
Developers can use the asset management API to add currencies, obtain token balances for wallet accounts, obtain token balances for observation accounts, obtain balances for specific currencies, obtain total balances for currencies, delete currencies, query currency lists, etc.
Third, in terms of transaction management. This includes how to send transactions and query transaction records. Developers can use the transaction management API to obtain data required for signatures, Gas prices, Gas limits, Nonces, etc., and perform address verification, query transaction details by transaction hash, query transaction details by order ID, query transaction lists by account, query transaction lists by address, etc.
Fourth, in other aspects. Developers can also use the API for chain-related information queries such as UTXO, currency information, etc.; or through Webhook, subscribe to block events and transaction event-related data, and create up to 20 subscriptions at a time, etc.
DEX Aggregator API
OKX DEX Aggregator is a one-stop multi-chain, DEX, and cross-chain aggregator, which has now aggregated 25+ cross-chains, 40+ public chains, and 400+ DEX, etc., and uses X Routing smart routing to simultaneously use multiple DEX for a single transaction. It provides users with better prices, better liquidity, and zero transaction fees, and also includes DEX market sections, limit orders, KYT security checks, and other functions.
The core mainly includes single-chain Swap and Bridge, both of which require on-chain data parsing to complete the entire transaction process. Single-chain Swap and Bridge combine different transaction modes based on the exchange currency pairs, such as completing transactions through source chain Swap + Bridge, or completing transactions in one step through Bridge, as well as completing cross-chain transactions in the form of source chain Swap + Bridge + target chain Swap. The XBridge contract, independently developed by OKX DEX Aggregator, is the core of the entire transaction, supporting cross-chain transactions between mainstream EVM chains, heterogeneous chains, and between EVM chains and heterogeneous chains.
Developers or professional users can use the DEX Aggregator API documentation to build the required Web3 transaction services and applications, such as Web3 wallets, DApp projects, and DeFi projects in various application scenarios.
The OKX DEX Aggregator API has core highlights such as multi-chain support, multiple cross-chain bridges and support for multiple DEX, stability, and high availability. Its response time is within 100 milliseconds and can provide a more optimal pricing path for free.

The OKX DEX Aggregator's proprietary X Routing algorithm can automatically find liquidity pools with better depth on the source chain, calculate prices, slippage, and transaction costs, and obtain better exchange quantities through smart order splitting algorithms. It then compares multiple high-quality cross-chain bridges to obtain better cross-chain quotes after calculating cross-chain quantities, cross-chain bridge fees, slippage, and transaction costs.
Developers can use the Cross-chain API to obtain the supported chains, currency lists, bridge information, path information, trade authorizations, transaction data, query transaction status, and more supported by the OKX DEX Aggregator.
Third, in terms of limit order functionality, the OKX DEX Aggregator's limit order is a process where users buy or sell tokens at a specified target price on decentralized exchanges. If the current market price meets the user's specified target price, the DEX Aggregator will automatically complete the transaction. Through the DEX limit order API, users can create and query limit orders through the interface and aggregate liquidity into the DEX Aggregator to enjoy better prices.
The OKX DEX Aggregator's limit order API features waiting for DEX Aggregator users to take orders, no slippage for limit order creators, and support for partial order execution. Developers can use the Limit Order API to obtain the supported chain lists, trade authorizations, currency lists, create limit orders, query limit orders, and more supported by the OKX DEX Aggregator.
