Financial systems that solve for trust at the market layer. Amplified upside, a floor under your downside, and leverage without margin calls. Or build your own product on the engine underneath.

One engine, two products.

Mayflower runs its own flagship financial system and gives builders the machinery underneath it.

Mayflower Reserve

A reserve-backed asset with a floor that can only rise, and credit against that floor which cannot be called.

Hold the upside. Keep a guaranteed way out.

Mayflower Reserve is a family of floating-value markets built from Assured Value Machines.

A long-term market position with visible downside boundaries, built-in liquidity, and credit that cannot be called.

A floor that only rises

Every Reserve share carries a guaranteed minimum redemption price, backed by verifiable reserves and enforced by the deployed contracts. As the market grows the floor rises with it, and each ratchet upward is permanent. No manager, governance vote, or departing liquidity provider can mark it down.

Borrow against the floor

Draw a zero-interest, non-recourse cash advance against the floor value of your position. The advance never exceeds guaranteed value, so the position stays solvent by construction and your collateral cannot be seized. It unlocks on repayment, and the upside stays yours throughout.

Provable solvency

When the price reaches the floor it stops falling. Every holder redeems at the same known price, so there is no advantage to moving first. Visible reserves are what make a run impossible.

Built-in liquidity

The market creates its own reserve as shares are issued, and that reserve is the counterparty to every redemption. Exiting a position does not depend on finding a new buyer.

A Reserve position behaves like digital property with built-in home equity. Its market value can rise, its guaranteed floor defines durable collateral value, and that value can be reached without a forced sale.

Launch products, not tokens.

Build your own financial product on the machinery that runs Mayflower Reserve. Revenue comes from usage rather than from trading against your users.

Four ways in, all running on the same primitive: a market that acts as its own counterparty, with a floor that can only rise. What changes is who arrives, and what they bring.

Launch a market

You have an asset that needs a market. Run one, or run a venue that hosts many.

Liquidity arrives with the buyers A price curve rises as supply grows, staying above the floor at every point. Beneath it the floor advances in discrete steps and never falls back. The shaded floor region is the reserve that stands behind every redemption. LIQUIDITY ARRIVES WITH THE BUYERS price floor buyers arrive, supply grows The floor is the reserve.
You bring
The asset, the audience, and the distribution.
Mayflower provides
A market that is its own counterparty, with no pool to seed and no market maker to hire.
Your users get
A floor that can rise and cannot fall, and an exit that does not depend on finding a buyer.
You earn
The fee schedule you set, on every market you run.

Back a treasury

You hold a native token. Make it the reserve asset.

Your token becomes the reserve Circulating supply flows into a reserve denominated in the native token. The reserve backs a reserve-backed asset issued to buyers, and fees from the market's activity flow back to the treasury. YOUR TOKEN BECOMES THE RESERVE circulating supply RESERVE floor reserve-backed asset fees treasury Supply leaves the market and sits behind a rising floor.
You bring
A native token and a balance sheet you would rather not spend.
Mayflower provides
A market denominated in your token, so every buyer of the reserve-backed asset is a buyer of yours.
Your users get
Floored exposure to your economy, and zero-interest credit against the floor without selling.
You earn
Fees on the market's activity, rather than paying market makers to defend a price.

Build on a listed market

You consume a market rather than create one.

Available today, not yet in use.

Your layer, on a market you did not create A product layer sits above a listed market. The market publishes its floor, reserve and position state onchain, and the product reads that state to build a vault, a yield mechanism or an interface on top of it. YOUR LAYER, ON A MARKET YOU DID NOT CREATE Your product vault, yield mechanism, interface reads state Listed market reserve and positions, readable onchain floor Market economics stay with the market.
You bring
The product surface: an app, a vault, or a structured position.
Mayflower provides
Reserve-backed assets whose positions, floors and reserves are readable onchain.
Your users get
Your product, with a floor underneath the asset it holds.
You earn
Whatever your product charges. Market economics stay with the market.

Launch an institutional product

You issue a fund or a real-world asset. Turn demand for a companion product into new subscriptions.

A joint design exercise around one existing product.

Capital arrives from outside the system New investor capital enters from outside, subscribes into the manager's existing fund, and the units that subscription creates are delivered to the companion market's reserve. The companion market issues a reserve-backed asset to the investor. The fund keeps its own mandate throughout. CAPITAL ARRIVES FROM OUTSIDE investor capital new, not recycled Your fund subscription creates new units. Mandate unchanged. RESERVE floor your fund units, held reserve-backed asset issued to the investor The capital is new. The fund keeps its mandate.
You bring
An existing digitally represented fund or asset interest, and the distribution you already have.
Mayflower provides
A companion market whose reserve is your asset, issued through primary subscription so new capital can land in your fund.
Your investors get
Exposure to the underlying asset, plus a demand-sensitive premium above a floor denominated in that same asset.
You earn
Your ordinary fee, while the demand-sensitive risk stays outside your fund.

The floor is denominated in each market's reserve asset rather than in dollars. What the guarantee covers, and what it does not .

The floor is a mathematical property of every market.

It is enforced by the protocol and backed by the reserve, and it holds for the same reason a sum holds.

The reserve is the market

Every purchase creates new shares and adds capital to the market's reserve. Every redemption destroys shares and pays capital back out. The market does not rent its liquidity from outside providers.

For the holder: There is always a protocol-defined redemption path rather than a hope that another buyer appears.

The floor is mathematically guaranteed

Under the stated model and valid protocol state transitions, the reserve remains sufficient to redeem every outstanding share at its stated floor. Solvency holds as an invariant of the system rather than a target someone monitors.

Guaranteed value can rise

The Assured Value Machine can reshape its price schedule while preserving reserve solvency, converting more of the market's value into guaranteed floor value. Designated revenue can also be invested directly into the floor.

For the holder: More of the position becomes permanently protected over time.

Guaranteed value becomes usable liquidity

A holder may pledge shares and receive an advance up to their floor value. Because the advance never exceeds the guaranteed collateral value, it carries no interest and no conventional liquidation process.
