ERC20 Interactor is a clean web UI that connects to a Stylus/Rust ERC-20 contract and lets users and developers perform all common token operations — view name, symbol, decimals, total supply, check balances, send tokens, set allowances, and call transferFrom. Ideal for testing, demos, hackathons, and teaching token mechanics.
Lending Agent lets users lend, borrow, or withdraw on AAVE and Arbitrum using simple natural language.
TriggerX is a decentralized automation protocol that enables smart contracts to execute tasks based on time, conditions, or external events in a fully automated and trustless manner.
