Through open-source initiatives and robust API development, OKX Web3 Wallet is making significant contributions to the blockchain ecosystem. These efforts not only foster technological innovation and improve development efficiency but also enhance system transparency, interoperability, and security. This approach ultimately benefits the entire Web3 community by improving user experience and promoting industry standardization.
While everyday users might not immediately notice these foundational elements, they form the "invisible infrastructure" that powers the OKX Web3 Wallet experience. This article serves as the first installment in a series exploring this infrastructure, focusing specifically on the comprehensive API framework that enables developers worldwide to turn their ideas into reality.
Understanding the OKX Web3 Wallet API Framework
APIs (Application Programming Interfaces) are sets of definitions and protocols that enable different software systems to communicate and exchange data. They allow developers to leverage existing functionality and data without building everything from scratch, significantly improving development efficiency and promoting system interoperability.
OKX Web3 offers a complete Web3 development solution called OnchainOS, a multi-chain Web3 development engine that standardizes chain and service integration. This standardization dramatically reduces development cycles and costs while providing essential modules including wallet services, DEX aggregators, marketplace functionalities, DeFi integrations, and comprehensive on-chain data solutions.
For developers looking to build their own Web3 services, OnchainOS presents a more efficient and economical choice. To further support developers, OKX Web3 provides extensive, well-documented API resources with detailed guides and visual aids available at their official documentation portal.
The OKX Web3 Wallet currently supports over 100 public chains and offers a unified experience across app, plugin, and web platforms. It encompasses five main sections: Wallet, DEX Aggregator, DeFi, NFT Marketplace, and DApp Explorer, including specialized markets for Bitcoin inscriptions and runes.

Wallet API: Core Functionality and Capabilities
As the central component of the ecosystem, the Wallet API provides non-custodial wallet technical solutions that help developers easily build on-chain services and applications. These include multi-chain wallets, DApp-integrated wallets, multi-chain Web3 applications, and exchange wallet services.
The Wallet API offers three core functions: multi-chain address aggregation with million-level address asset statistics capability, easy access to 60+ networks including heterogeneous multi-chain ecosystems and BTC asset protocols, and high availability with implemented interface and system monitoring to ensure smooth integration.
Developers can set up a wallet in just three steps using the Wallet API, easily accessing 60+ networks including popular options like EVM, Solana, TRON, and BTC, with support for emerging ecosystems like inscriptions. Future developments will include MPC wallets and AA smart wallet account capabilities.
The Wallet API covers multiple core modules that address basic asset management and transaction needs:
Account Management
Unlike typical single-address query models, the Wallet API provides structured multi-address subscription queries. Developers can associate multiple addresses with a single account, efficiently querying asset status and transaction history across multiple chains.
The API offers two account types: wallet accounts (requiring message signatures for authentication, allowing custom token additions and transaction sending) and watch accounts (no signature required, displaying all OKX-platform tokens by default, without transaction sending capability).
Asset Management
This includes adding subscription currencies to accounts, obtaining corresponding asset balance quantities, viewing total assets, and removing unwanted assets. Wallet accounts can add and manage custom currencies, while watch accounts can only access balances for currencies already supported by the Wallet API.
Transaction Management
This covers sending transactions and querying transaction records. Developers can obtain data required for signatures, Gas price, Gas limit, Nonce, and perform address verification, transaction detail queries by hash, order ID queries, transaction list queries by account or address, and more.
Additional Features
Developers can also query chain-related information such as UTXO and currency details, or use Webhooks to subscribe to block and transaction event data, with support for批量 creating up to 20 subscriptions at once.
DEX Aggregator API: Advanced Trading Capabilities
The OKX DEX Aggregator is a one-stop multi-chain, DEX, and cross-chain aggregation solution that currently integrates 25+ cross-chains, 40+ public chains, and 400+ DEXs. Through its X Routing intelligent routing system, it enables single transactions across multiple DEXs, providing users with better prices, improved liquidity, and zero transaction fees while offering additional features like DEX market boards, limit orders, and KYT security detection.
The core functionality includes single-chain Swap and Bridge operations, both requiring on-chain data parsing to complete transactions. These can be combined in different patterns: source chain Swap + Bridge, Bridge-only transactions, or source chain Swap + Bridge + target chain Swap for cross-chain transactions. The proprietary XBridge contract serves as the core component, supporting cross-chain operations between mainstream EVM chains, heterogeneous chains, and between EVM and heterogeneous chains.
👉 Access multi-chain trading solutions
The DEX Aggregator API features multi-chain support, multiple cross-chain bridges and DEX integrations, stability, and high availability with response times under 100 milliseconds while providing optimized price quotation paths free of charge.
Exchange Functionality
The OKX DEX Aggregator integrates liquidity sources from decentralized exchanges like Uniswap, Curve, and Balancer, automatically finding liquidity pools with better depth while comprehensively calculating price, slippage, and transaction costs through intelligent order splitting algorithms.
Cross-Chain Capabilities
The aggregator integrates quality cross-chain bridges including Circle CCTP, Stargate, Across, Wormhole, and SWFT, providing users with multiple cross-chain path options. The proprietary X Routing algorithm automatically seeks liquidity pools with better depth during source chain transactions while comparing prices across multiple quality cross-chain bridges.
Limit Order Features
OKX DEX Aggregator's Limit Order functionality allows users to buy or sell tokens at specified target prices on decentralized exchanges. When market prices meet the specified target price, the DEX aggregator automatically completes the transaction. The Limit Order API enables users to create and query limit orders while aggregating liquidity into the DEX aggregator for better pricing.
Marketplace API: NFT and Digital Asset Trading
OKX Marketplace covers EVM NFT markets, Runes markets, Ordinals markets, and issuance markets, supporting 26 mainstream public chains including Bitcoin and Ethereum.
EVM NFT Marketplace
The OKX NFT Marketplace is a one-stop decentralized NFT aggregation trading platform that integrates markets including OpenSea, Magic Eden, and LooksRare. It allows NFT holders to list their works on multiple markets simultaneously with lower transaction costs and higher liquidity while supporting multi-chain NFT creation and cross-platform trading.
The NFT API provides data query and transaction functions, including NFT and collection information queries, transaction data queries, one-click listing across multiple markets, and batch purchasing of lower-priced orders from multiple markets.
Runes Marketplace
OKX Runes Market is the industry's first platform to offer Runes trading on mobile apps, supporting zero-platform-fee batch purchases and etching of Runes assets. Developers can access collection information, popular collections, transaction history, wallet assets, order information, and submit listings through the API.
