The OKTC ecosystem continues to evolve with significant technical upgrades, expanding community engagement, and growing ecosystem partnerships. This update highlights key developments from March 2025, focusing on performance enhancements, infrastructure improvements, and broader integration within the decentralized ecosystem.
Core Developments Overview
March marked a pivotal month for OKTC as the network advanced toward its future mainnet launch. Key milestones include the integration of Chainlink oracles, major performance optimizations, and the successful completion of a large-scale joint public test. The network’s infrastructure has been strengthened through improved RPC services, enhanced EVM execution efficiency, and updated address algorithms for better Ethereum compatibility.
These upgrades are not just incremental—they represent a strategic push to ensure OKTC delivers high throughput, robust security, and seamless user experience upon mainnet launch.

Ecosystem Expansion and Community Engagement
Community Forum Launch
The official OKTC community forum is now live, serving as a centralized hub for announcements, technical discussions, and user feedback. This platform enables real-time communication between developers, validators, and community members, fostering transparency and collaboration.
Chainlink Oracle Integration
OKTC’s future mainnet will integrate Chainlink, the industry-leading decentralized oracle network. This integration ensures secure and reliable price feeds for DeFi applications built on OKTC. By leveraging Chainlink’s proven security and scalability, OKTC strengthens the foundation for trustless smart contract execution.
Chainlink oracles will support critical use cases such as lending protocols, derivatives platforms, and automated market makers (AMMs), ensuring accurate off-chain data is delivered on-chain without single points of failure.
Joint Public Test Phase One Completed
From March 11 to March 16 (HKT), OKTC conducted its first large-scale public test in collaboration with 20 project teams. Over 5,000 community members participated in testing dApps across the testnet, helping identify bugs and optimize user flows.
Participants were rewarded with OKT tokens—totaling 2,000 OKT—for their contributions. This initiative not only improved network stability but also deepened engagement across the developer and user communities.
Wallet and dApp Ecosystem Growth
Major crypto wallets—including TokenPocket, BitKeep, HyperPay, ONTO, and AoLink—have launched dedicated dApp sections for the OKTC testnet. Users can now seamlessly interact with decentralized applications directly within these wallets, lowering entry barriers for new users.
This integration signals growing confidence in OKTC’s infrastructure and usability.
Security Partnership with Armors
OKTC has partnered with Armors, a leading blockchain security firm, to provide professional audit services for projects launching on the network. This collaboration enhances the overall security posture of the OKTC ecosystem by ensuring smart contracts are rigorously tested before deployment.
Armors’ involvement helps mitigate risks associated with vulnerabilities, reinforcing trust among developers and users alike.
Updated Testnet Faucet Access
Due to high traffic, previous testnet faucet channels via Gitcoin, Discord, and other platforms have been temporarily suspended. Users requiring testnet tokens can now obtain them through the official Slack channel, which offers a more stable and scalable distribution method.

Testnet Performance Optimization
1. RPC Service Enhancement – QPS Doubled
To handle increasing demand, OKTC optimized its RPC node architecture:
- Resolved CPU spikes during peak loads
- Refined database queries and schema design
- Achieved 2x increase in QPS (queries per second)
This improvement ensures smoother interactions for wallets, explorers, and dApps relying on RPC endpoints.
2. EVM Execution Efficiency Boost
OKTC significantly improved EVM module performance:
- Refactored EVM state DB interface to reduce redundant writes
- Enhanced ABCI (Application Blockchain Interface) efficiency
- Accelerated consensus finality
- Fixed gas refund logic to ensure proper refunds even when transactions fail
As a result, block production speed has increased substantially, reducing latency and improving transaction throughput.
3. RPC Domain Upgrade
The testnet RPC endpoint has been standardized to:
👉 https://exchaintest.okexcn.com
Key benefits:
- Unified domain reduces confusion
- HTTPS encryption enables secure mobile access
- Supports CORS for cross-origin requests
- Prevents browser redirection issues caused by HTTP-to-HTTPS auto-conversion
4. WebSocket Support Expanded
OKTC now supports four core WebSocket subscription methods:
newHeadslogsnewPendingTransactionssyncing
Responses are fully compatible with Ethereum’s format, easing migration for Ethereum developers. Comprehensive documentation is available at:
okexchain-docs.readthedocs.io/en/latest/developers/basics/websocket.html
5. New Query Node Configuration Flags
Developers can now fine-tune query node behavior using new startup parameters:
close-mutex: Disables concurrency lock for faster queriesfast-query: Enables rapid query mode with data stored in WatchDBenable-bloom-filter: Optimizeseth_getLogscalls using bloom filters
These flags empower node operators to tailor performance based on their operational needs.
6. Address Algorithm Alignment with Ethereum
To ensure full compatibility with Ethereum tools and wallets:
- Changed
coinTypefrom 996 to 60 - Now fully aligned with Ethereum’s BIP-44 standard
This change allows users to use the same mnemonic phrases and private keys across both networks—simplifying onboarding and improving interoperability.
7. Address Prefix Shortening (In Testing)
Based on community feedback about address length:
- Proposing to change prefix from
okexchaintoex - Example:
ex1...instead ofokexchain1... - Currently under testing; not yet deployed
This update aims to enhance readability and reduce input errors.
8. Additional Enhancements
- Implemented gas-price-priority transaction packaging (under testing)
- Strengthened anti-DDoS mechanisms by increasing attack costs at the protocol level
Frequently Asked Questions (FAQ)
Q: How do I get testnet tokens for OKTC?
A: Testnet faucets on Gitcoin and Discord are currently closed due to high traffic. Please visit the official OKTC Slack channel to claim test tokens.
Q: Is OKTC compatible with Ethereum tools?
A: Yes. With the updated coinType=60 and EVM equivalence, MetaMask, Hardhat, Truffle, and other Ethereum development tools work seamlessly with OKTC.
Q: When will the mainnet launch?
A: While no official date has been announced, recent upgrades—including Chainlink integration and performance boosts—indicate mainnet is approaching readiness.
Q: Can I build dApps on OKTC now?
A: Absolutely. Developers can start building on the testnet using updated SDKs and WebSocket APIs. Documentation is available at the official OKTC docs portal.
Q: Why was the address prefix changed?
A: To improve usability. The original “okexchain” prefix was long and prone to errors. The proposed “ex” prefix is concise and user-friendly.
Q: How does OKTC prevent DDoS attacks?
A: Protocol-level changes have increased the cost of spamming the network, making DDoS attacks economically unviable while maintaining low fees for legitimate users.
