01The currency

Introducing open money.

Moony is permissionless money: payments straight from one person to another, with no intermediaries and no authority able to block, freeze or reverse them. It is built to be two things at once: sound, its supply fixed forever, and open, a digital public good governed by immutable code.

Moony notes denominated in dollars, euros and more

Fixed supply21,000,000Every coin that will ever exist.

Sound

Moony is sound money.

The supply is fixed at 21 million units and the mint authority is permanently revoked. No mechanism exists to create more. Money that can be printed loses purchasing power as its supply expands. Moony cannot be diluted or debased.

Open

A new monetary standard.

Moony is governed by a single public program: MIT-licensed, immutable, and the same for everyone. It prices every coin, distributes the supply, and holds the reserve, with no discretion anywhere in the system.

03The Reserve

Reserve-based liquidity.

The Reserve is an immutable public program that prices, backs and settles every coin. Deposit dollars to receive Moony; redeem any time at the curve’s price.

The reserve asset

Backed by real dollars,
redeemable anytime.

Every coin in circulation is backed by USDF, a US-dollar stablecoin fully reserved in segregated Coinbase custody. Every redemption is paid from those dollars, on demand.

Deposit dollars, receive Moony. Send USDF to the contract and receive coins at the live curve price. The rules are identical for everyone, from the first coin to the last.
Redeem anytime, at the curve price. Redemptions are the only way dollars leave the Reserve. No company, foundation or insider can withdraw them. A 1% protocol fee applies on redemption.
Backing that deepens. Moony is not pegged: coins redeem along the same curve that distributes them. Deposits accumulate in the Reserve as the supply spreads, deepening liquidity for all.

04Open network

A digital public good. Shaped by independent participation.

No company manages the network and no one holds privileged access. It grows as independent participants build, integrate and transact, each on their own terms.

Open by default

Money is infrastructure, and it
should belong to everyone.

public gooddecentralizedpermissionless

The web was built on open protocols: public standards that no company owns and anyone can build on. Moony applies the same principles to money. The protocol is public, the rules are fixed in code, and everyone meets them on equal terms.
