Security and innovation go hand in hand: the asset custody revolution in the Web3 eraAt the 2025 Hong Kong Web3 Carnival, OKX Chief Business Officer Lennix bluntly stated that "self-custody wallets will become the mainstream in the future", and this view quickly sparked heated discussions in the industry. Self-custody (Self-Custody), as the core logic of decentralized finance (DeFi), gives users absolute control over private keys and completely gets rid of the risks of centralized platform custody. However, this model also needs to balance security, multi-chain compatibility and user experience-this is exactly the direction of the current Web3 infrastructure.The technical architecture of the XBIT decentralized trading platform uses zero-knowledge proof (ZKP) and multi-signature mechanisms to ensure the self-management of user assets while avoiding the potential threat of private key loss or theft. In addition, the platform's built-in "suspicious address identification system" can monitor on-chain transactions in real time, actively intercept blacklist-related behaviors, and add a line of defense for security.

The rise of multi-chain ecology: from technology islands to an interoperable futureLennix emphasized that the success of OKX wallet stems from "deepening the multi-chain ecology", and this trend has become an industry consensus. With the performance improvement of public chains such as Ethereum, Solana, and Avalanche, and the maturity of cross-chain bridges and Layer2 expansion solutions, users' demand for seamless asset switching and low-cost interaction has surged.XBIT decentralized exchange platform also targets this pain point, supporting cross-chain asset transactions of more than 50 mainstream public chains, and achieving optimal price execution through aggregated liquidity protocols (such as DEX aggregators). Its engineering team revealed that the platform will integrate account abstraction technology in the near future to further reduce the threshold for multi-chain operations, allowing ordinary users to enjoy Web3 without understanding complex on-chain logic.

Compliance and innovation game: the survival rules of decentralized platforms

In the Carnival roundtable forum, Lennix admitted that "compliance is a unique challenge for self-hosted wallets." Global regulators are increasingly stringent in their requirements for anti-money laundering (AML) and user identity verification (KYC). How can compliance be met under a decentralized framework? OKX's answer is: track high-risk behaviors through on-chain data analysis tools, while opening developer interfaces (APIs) to assist third parties in building compliant applications.XBIT decentralized exchange platform adopts a "modular compliance" strategy, allowing users to choose whether to bind KYC information. Although unverified accounts cannot participate in high-value transactions, they can still enjoy basic functions. This flexible design not only meets the risk stratification control requirements of EU MiCA and other regulations, but also retains the core concept of decentralization.Long-termism VS short-term profits: Who is defining the future of the industry?

OKX President Hong made it clear in his speech that "we will not pursue short-term rankings and focus on sustainable ecological construction." This position coincides with the development strategy of XBIT decentralized exchange platform. In the current market, many platforms have launched high-leverage derivatives or low-quality tokens to compete for traffic, resulting in the accumulation of systemic risks.In contrast, XBIT insists on innovation in underlying technology. The recently launched "Smart Contract Bug Bounty Program" attracts white hat hackers from all over the world to participate in security audits. Its open source code base has fixed 12 potential vulnerabilities. The platform also jointly released the "Multi-chain Security Guide" with academic institutions to popularize knowledge such as private key management and gas fee optimization to users, and promote the industry from speculation to value creation.

Self-custody and multi-chain - the two wings of Web3 infrastructureFrom the discussion at the Hong Kong Web3 Carnival, it can be seen that the integration of self-custody wallets and multi-chain ecology is reshaping the power structure of the cryptocurrency world. Whether it is OKX's technical investment or the exploration of security and compliance by decentralized exchange platforms, they all point to the same goal: to allow users to truly control digital assets while lowering the threshold for entering Web3.As Lennix said: "The balance between innovation and compliance will be the key to the success of the next generation of infrastructure." In this wave of subversion and reconstruction, only platforms that take into account user sovereignty, technical depth and regulatory dialogue can become future leaders.
