Zerion's community dinner series has grown from a single experiment at Ethereum Denver to **007 cities worldwide**. The London dinner was particularly successful, prompting the introduction of **The Zerion Key** - a new system that grants holders access to attend any future Zerion dinner globally. **Key highlights:** - Started as one-time experiment, now spans multiple cities - Focuses on connecting crypto communities in underrated locations - New Key system creates exclusive access to future events - Community can suggest next dinner locations The initiative builds on Zerion's recent activity at major events like EthCC, where they hosted multiple side events, API demos, and community gatherings across Berlin and Cannes. *Drop your city suggestions to potentially host the next dinner.*

**DeFi positions are scattered and messy** across multiple chains - from LP shares to staked assets and lending collateral. **Zerion API solves this complexity** by providing: - 8,000+ protocol positions for any EVM wallet - **26+ chains accessible with one API call** - Normalized and enriched data - Values in ETH, BTC, USD, or fiat currencies **Already trusted by major teams** including Safe, Waltio, and CMT Digital. The same robust data infrastructure that powers Zerion Wallet is now available for developers to integrate into their own applications.

Developers can now access DeFi positions with minimal code complexity. The new implementation offers: - **Streamlined API calls** requiring just a few lines of code - **Advanced filtering options** for precise data retrieval - **Best practice guidelines** for app integration This update simplifies the process of integrating DeFi position data into applications, making it more accessible for developers building financial tools and portfolio trackers. The solution addresses common pain points in DeFi data access while maintaining robust functionality.

**Zerion API** offers noise cancellation for messy blockchain data, similar to how headphones filter out unwanted sound. **Major adoption** includes: - Uniswap wallet - Rainbow wallet - Privy - 200+ development teams The API **silently powers** many consumer apps and wallets in the web3 space, providing clean data infrastructure that developers can build upon. **Free developer keys** are available for solo builders and teams looking to integrate clean blockchain data into their applications.
