In Q4 2024, the Harmony team achieved significant advancements in protocol stability, product innovation, and community growth. Below each member highlights their contributions to our protocol, community outreach, and product development.
Successfully completed the leader rotation process, ensuring a smooth mainnet launch by enhancing synchronization mechanisms to guarantee uninterrupted block production. Introduced a bypass for inactive leaders, significantly reducing potential downtime and improving network resilience.
Additionally, I worked on improving local network development, enhancing network insights, and refining proposal signals to optimize block production for multi-BLS nodes.
In Q4, I focused on enhancing staking functionality and addressing critical protocol challenges. A significant part of my efforts was dedicated to investigating consensus-related issues, particularly a bug causing multiple block proposals. While the final resolution is still in progress, my thorough analysis clarified the problem's scope and outlined actionable next steps for resolving it.
To strengthen protocol stability, I rigorously tested and reviewed pull requests addressing post-HIP32 challenges. This included refining leader rotation logic and optimizing multi-BLS validator consensus mechanisms. Additionally, I updated the localnet to replicate mainnet conditions, uncovering critical edge cases such as consensus failures during single-node quorum scenarios.
Operationally, I worked on improving the network by developing and implementing scripts to identify anomalies in block production. My proactive collaboration with the validator community was instrumental in mitigating these issues, including a significant 12-minute shard 0 consensus loss. Detailed incident reporting and follow-up ensured transparency and informed future improvements.
This quarter, I tackled several critical areas to improve network stability, performance, and decentralization. A lot of my focus was on addressing stream disconnectivity issues and enhancing the P2P layer. I optimized the way streams handle connections and refactored parts of the system to make error handling more resilient. Stream concurrency and lock management were improved, along with significant updates to the Staged Stream Sync module, making it more reliable and easier to maintain. I also added support for Trusted Nodes in the P2P host, enhancing the flexibility and security of the network.
Another big milestone was the successful HIP32 hardfork, which brought the network much closer to full decentralization. It was a proud moment to see the community and the infrastructure align for such a critical upgrade.
On the consensus side, I conducted an in-depth review of the leader rotation process, identified edge cases, and implemented fixes to improve reliability. I also addressed issues with multi-BLS validators, such as improving quorum calculations and fixing problems with multiple block proposals. These changes ensure smoother operations for validators and better overall performance.
Finally, I resolved a resource limitation issue impacting boot nodes, making them more efficient at handling traffic. Alongside this, I worked on adding capacity to support concurrent requests across streams and refined the P2P muxers for better performance. This quarter was all about solving major pain points and laying the groundwork for a more decentralized and reliable network.
Development Pump.ONE contracts: the logic for the token factory, competition and liquidity manager is fully implemented. Implemented counting of investments, determining the winner and publishing on Uniswap v3. Additional logic has been developed for linking tokens to the competition ID: buying and selling is allowed only within the current competition - then the user can only convert his tokens into winner tokens, or publish on Uniswap if this token is the winner. Several integration tests have been developed. Contracts serve as the basis for the Pump.ONE application. Added integrations with API services and frontend client.
Developed Staking Vault contracts based on Erc-4626 with a Reward distributor contract. Additionally, the 1sDAI token was added to the bridge, which was integrated into the Staking Vault. Added logic for commission deduction, as well as rewards by epoch.
Also worked on the development of several new layerzero bridge features: integration with Solana (with the transition to LayerZero V2) - implemented draft only for the test network. Updating npm bridge packages and worked on bridge-cli for translations from the command line.
This quarter, I focused on launching of Pump.ONE project, a memecoin marketplace on the Harmony chain.
While working on this project, I created various services: Pump.ONE client, backend(indexer + API service) and trading bot. During the development process I worked on the user interface, integration with smart contracts, end-to-end testing and improvements based on user feedback. In the backend app, I implemented mechanics to store token metadata, upload images, user authorization based on signed messages and JWT tokens, REST API and tokens indexer.
I've also implemented Harmony yield enhancer client, added new features for the new Harmony Explorer: ONE/ETH toggle persistent state, displaying transaction value at the time of transfer.
In Q4 2024, I developed a proprietary array-based bonding curve contract to address licensing constraints with Mint Club's contracts. The implementation included price calculation and token management functionality, with constructor-initialized stages and standardized curve stages across tokens. I built a Next.js client application with token listing, purchasing, and price calculation features. This work was initially planned for integration with 1.country for domain-based token creation and was later contributed to the pump.fun project.
I enhanced Harmony1Bot by integrating multiple AI models including xAI's Grok, Gemini 1.5, Claude 3.5 Sonnet, and OpenAI's o1, while optimizing their command structures for better user interaction. I implemented a sliding window mechanism for infinite chat context and a session-based cleanup system. The bot's reliability improved through Sentry integration across all environments and telegram error notifications. I also developed a video processing system with semantic search and clip generation capabilities, evolving from MoviePy to an FFmpeg-based approach with subtitle handling features. Currently, I'm extending the harmony-llm-api with a JWT-based payment system for general-purpose usage, implementing prepaid user functionality with balance checks and model cost logic.
This quarter, I focused on expanding content creation, enhancing co-marketing efforts, and boosting audience engagement. I learned Descript to produce videos for projects like ElonxCountry and JensenxCountry and explored new animation techniques by integrating Pika with MidJourney. Additionally, I manually animated graphics in Jitter for PumpONE and the crypto and AI newsletters. To support PumpONE, I joined weekly development syncs and contributed to writing disclaimers and documentation for its upcoming launch.
I led co-marketing campaigns with partners like Pear AI, Kings and Quests, ONE Show, Band Protocol, FlappyH1, RMC, CoinGecko, ElonxCountry, and HeyEddie, driving collaborative growth across platforms. Twitter performance grew significantly, reaching 953,000 impressions (+5%), 50,000 total engagements (+45%), 15.6K likes (+22%), and 3.1K reposts (+29%). I also wrote monthly newsletters showcasing team progress, community highlights, and founder insights. Using NotebookLM, I created AI podcast summaries of these updates, repurposing the content for YouTube and Substack.
"19 days after we shipped the systems to them, they had a super cluster up and running. 19 days. You can't do that. If you were cobbling together all these different chips and writing the software, you'll be lucky if you could do it in a year."
My first 2.5 months at Harmony were all about assessing the status Quo, analyzing the ecosystem for its strengths and weaknesses, and identifying a potential direction where to go from here. In terms of Defi, I developed the strategy to funnel returns offered outside of Harmony into our ecosystem. In addition, there are two user groups that we can target:
New/non-native users who dont know about farming
Power users able to deploy advanced strategies
All product developments will evolve around those two user groups.
Achieved so far:
The treasury farms yield to distribute it to our products after potential strategies have been elaborated and assessed
1sDAI (11.5% APY) is deployed on Harmony
The yield Enhancer product conception is ready and to be deployed (target is within December)
Several product descriptions targeting more advanced strategies are ready (Lending Market, 1Swap Gauge)
I architected Harmony's DeFi suite expansion, focusing on accessibility and higher yields, delivering key products to new heights. Swap saw a 300% increase in TVL, and a 4,470% surge in trading volume. Lend followed a similar expansion, reaching a 250% increase in supply.
I led the Yield Enhancer development from strategy to implementation, building the frontend in typescript and coordinating ERC-4626 vault deployment. The first phase is live with 1sDAI, delivering 12.5% APY through Sky Protocol's yield-bearing stablecoin available within the Harmony ecosystem. I also pioneered Pump.ONE's innovative concentrated liquidity model with Stephen, optimizing for user collaboration over liquidity fragmentation. I drove the adoption of SimpleSwap, reaching 12.5% conversion rate and enabling seamless ONE acquisition across our ecosystem.
I also strengthened Harmony's market presence by securing Swap listings on DefiLlama and DexScreener, leading our recovery multisig custodian election, and driving community engagement through ONE Show presentations that reached 854 concurrent listeners and generated over 20k post views.
This quarter, my main focus on enabling ERC-4337, account abstraction, on the Harmony network. Initially, I successfully developed and launched Stackup's Golang implementation of the bundler node, which successfully processed user operations on the Testnet. With the halt of Stackup's development, my goal transitioned to Pimlico's implementation of the bundler node, Alto.
I updated and implemented Harmony's node to simulate user operations to be in accordance to bundler functionality, eth_call. In addition, I successfully launched Alto on Harmony's Testnet and Mainnet. EntryPoint.sol, EntryPointSimulation.sol, and BaseAccount.sol were deployed in order to support to basic functionality of account abstraction, as well as bundlers. Along these necessities, Base's smart wallet contracts were fully launched in both network to support account asbtaction.
Over the past three months, I focused on implementing bonding curve token models and achieving millisecond-level precision in video transcription. I developed and tested smart contracts using linear, exponential, and sigmoid curves for dynamic token pricing, optimizing them for DeFi applications like liquidity provisioning and fundraising. To demonstrate their practicality, I deployed demos showcasing real-time price adjustments while ensuring gas efficiency and seamless blockchain integration.
On the transcription side, I built an automated pipeline with AI tools like Whisper, Deepgram, and AssemblyAI, achieving millisecond-aligned timestamps and enabling batch processing with speaker diarization for multi-speaker scenarios. Additionally, I explored the AI agent ecosystem, testing platforms like Virtuals Fun and Magick for character creation and investigating pump.one contracts to integrate AI and decentralized technologies effectively.
Simplified onboarding and offboarding to HarmonyONE via $WAGE tokens.
Added liquidity and submitted a pull request to integrate BaseUSDC on swap.harmony.one.
