Meridian is neutral, non-custodial infrastructure for creating ETFs and tokenized-equity baskets that work 24/7, with an honest price even when the market is closed.
Meridian is a neutral, non-custodial infrastructure layer for creating and running tokenized-equity baskets (on-chain ETFs) that stay usable around the clock.

The problem it addresses is the weekend gap: tokenized stocks trade on-chain 24/7, but the equity market that prices them is closed about 80% of the week, so a fund's value goes stale and existing oracles freeze at the Friday close. A fund built on a stale price can be drained on a ghost value; a fund with no off-hours value just defers the problem.
A price-safety engine that publishes a 24/7 NAV together with a confidence band and a safe flag, so a fund always knows when a price can be trusted. It fuses many independent sources with a depth-weighted median (depth being the dollars it takes to move a price), a per-source weight cap, and a divergence filter to resist manipulation, and it is read-only: it never settles value, it only signals when value is safe to act on.
A non-custodial create and redeem system: anyone deploys a tokenized fund in one click, and holders enter or exit with a single token, either in-kind at any hour with no price needed, or in cash that settles forward at the next real market open (an estimate is never used as a settlement price), or as instant USDG-cash at the 24/7 value inside a safety buffer.
Conceived and built during the buildathon. We started with market research and a scientific paper that derives and validates the 24/7 price model on real on-chain data, confirming direction against the Monday open at 0.91 correlation and calibrating the confidence band to 67% at one sigma and 95% at two. On top of a price-safety core (a keyless multi-oracle committee with a depth-weighted median, a confidence band, and a safe flag) we built four fund types from one engine: Static, Managed-fee, Rebalanced, and a USDG-priced Index fund. We also built the off-chain backend, a React frontend with a wallet-free demo and a production build, and a simulation of the manual market-maker role that runs the full lifecycle. All contracts are deployed and verifiable on Robinhood Chain testnet, alongside a live playground, a slide deck, a landing hub, and full docs.
No prior funding. The project was conceived and built recently during the buildathon, and we have not raised any investment.
