Metacade builds competitive onchain gaming and agent products powered by MCADE. The core idea is that crypto communities already compete — over calls, narratives and conviction — but have no venue for it. Metacade builds that venue: arenas where characters drawn from crypto culture compete, and where outcomes are staked, settled and recorded onchain rather than argued about. The platform spans a fighting arena, onchain racing, and agent surfaces that let communities interact with those products where they already are. MCADE is the token across all of it, capturing value through match rake with burn and treasury accrual. Work is built in the open and shipped in stages, with each economic mechanism proven on a live chain before the next is layered on.
Arena Project Home is a reference implementation of two small contracts on Robinhood Chain.
ProjectHomeRegistry lets a project declare its canonical home onchain — slug, owner, metadata URI, home chain ID, treasury reference and an active flag — so anyone can resolve where a project actually lives rather than trusting an offchain link.
OracleGuard reads a single official Chainlink feed and returns an explicit validity state alongside the price, instead of a bare number the consumer has to trust. Staleness, market session and feed health are surfaced as state.
Neither contract is payable and neither takes custody. Both are verified on Blockscout with exact bytecode matches, and a public read-only frontend renders live registry and oracle state straight from the chain.
All of it. The repository was initialised on 18 September 2026, four days into the buildathon, and every commit dates from 18 to 21 September. Nothing was carried in from earlier work. Built in that window: ProjectHomeRegistry (152 lines) and OracleGuard (312 lines) in Solidity, both using OpenZeppelin AccessControl; five Foundry test suites including a fork test against the live Chainlink feed; a chain-aware deploy path rehearsed on Robinhood Chain testnet before mainnet; a post-deploy role handoff script that grants every role to a fresh admin and renounces the deployer's own, with pre-flight guards and post-condition assertions; and a Next.js read-only frontend that renders registry and oracle state live from the chain. Deployed to Robinhood Chain mainnet on 21 September across 14 transactions. Both contracts are verified on Blockscout with exact bytecode matches. The deploying key now holds no roles on either contract. Ten pull requests, all with CI covering contracts, frontend and a secret scan.
Seed funded.
