Viem

A library for interacting with Ethereum and other EVM-compatible blockchains.

Viem is a TypeScript interface for EVM blockchains that offers modular architecture, comprehensive type safety, and improved performance over alternatives.

It provides first-class support for public, private, and contract actions with built-in parsing, validation, and error handling for blockchain interactions.

Experience:

Implemented Viem in Opyn trading interface for type-safe contract interactions with Arbitrum Testnet via Alchemy RPC endpoints.

Built a custom EVM event indexer for BitLauncher using Viem EVM event subscriptions, capturing and processing auction data in real-time.

Developed BasilicEVM with Viem as the core blockchain interaction layer, focusing on type safety and performance optimization.

Created a custom token bridge for swapping stablecoins to USDCred tokens in BitLauncher using Viem for contract interactions.

Architected wallet interfaces with Viem for displaying real-time EVM balances through token balance subscriptions.

Opyn

Opyn is a decentralized options protocol on Arbitrum that raised $6.7M Series A funding led by Paradigm. Their main product Squeeth is a notable DeFi-native derivative. I implemented their initial trading interface and data indexing setup for Arbitrum Testnet using Next.js, Ponder, and viem/wagmi.

bitlauncher

BitLauncher is an AI and crypto launchpad platform that provides early access to promising AI unicorn startups through token sales and auctions. It features a batch auction system for token sales, ensuring fair and transparent price discovery. Participants bid during a fixed period, and tokens are distributed at a uniform price, eliminating manipulation and ensuring equal opportunities for all investors.
