ExecutionHub is a non-custodial DeFi hub that lets users connect their own wallet, create automated limit orders, swap tokens, and bridge assets across compatible networks. The goal is to keep DeFi user-controlled while improving execution clarity, route review, automation and cross-chain UX. For this Buildathon, I want to expand and refine ExecutionHub on Arbitrum, focusing on safer on-chain operations without custody.

VVVKernel is a permissionless payment and access layer on Base that wraps Venice AI with on-chain micropayments, a staking-based tier system, and a fully compliant Model Context Protocol (MCP) server.
ByHuman is building a writing receipt protocol for the AI era. As AI-generated text floods the internet, readers, platforms, publishers, and online communities are losing reliable trust signals for authorship.

ByHuman solves this from the other side: we capture composition evidence at the point of writing, including what was typed, pasted, edited, and preserved, then generate a signed writing receipt. Receipt hashes are anchored on Arbitrum, while the original text stays off-chain, creating a public, tamper-evident verification layer for online writing.
AfreeKart is a programmable escrow infrastructure project for commerce, using smart contracts to enforce safer buyer-seller transactions and reduce trust friction in online trade.
