Tokenomics, in full.
Gold stays inside the game; what you find is yours to sell. Companions are discovered in the world, never sold by us. Honest custody today, code-enforced trust tomorrow. Here is exactly how it all works — and what it deliberately does not do.
Last updated · September 2026
One purchase to enter. Free to play forever.
The $20 founding NFT is the primary onboarding money-in moment — not the only way money can enter, but the only purchase the game ever requires. Money can come in; gameplay value never cashes out.
Found, not sold
Founding companions mint at $20, capped at 2,500 \u2014 the one time we sell one. After that we never do: every companion is discovered in the world by a player. What you own, you found, minted, or bought from someone who did.
Free after mint
No premium tier, no pay-to-win, no subscription. Once you hold a companion, the whole game is open.
No required second spend
Progression is never purchased. Optional extras exist — cosmetics, NFT trading — but nothing that grants gameplay power is ever for sale.
Play creates Gold, progression and companion history. Gold powers the internal economy. Ownership and creative work produce resellable assets. Ownership trades settle in SOL or USDC between players. Gold itself never cashes out.
You can still profit from what you own. Discovered companions — especially evolved ones — are yours to resell. Rarity here is a measurement rather than a label: a companion's form has 145,379,840 variants, its mind has over 12 quintillion, and we score how unusual that mind actually is against every other companion. Because personality drifts with how a companion is treated, that score moves over its life. A companion's value can grow with its rarity, personality, care history, training, cosmetic identity, and sanitized memory-derived life-state. When a companion is sold, private prior-owner details are stripped, but the evolved non-private companion state transfers to the buyer. That is NFT character ownership resale — not gameplay-currency withdrawal.
A closed loop, governed by your companion.
In-game currency is a soft currency — credits / gold — tracked off-chain. It is earned by playing and spent only inside the in-game marketplace. It is never cashable for real money.
Closed-loop soft currency
Gold enters when you play and leaves when you spend it in the marketplace. It cannot exit the system. Earn rates and prices are founder-tunable so the economy stays healthy over time. Because it never bridges to real money, there is no incentive to farm it for profit.
Companion as economic agent
Your companion is an active participant in the in-game market — it trades on your behalf. Critically, each companion action burns in-game coin. That burn is an anti-bot governor: it makes automated grinding expensive while keeping the human earn-rate generous.
One on-chain token. Clearly bounded role.
A Token-2022 mint on Solana mainnet. Its address, supply, and authority status are public and verifiable on-chain. Here is what it is — and explicitly what it is not.
$MRDOPPLER
Community memecoin. Vanity utility only — no economic effect on the game.
- Mint address
- GBg9PhmkRvVdv1PdiziwH7488NrkE7fUkS7XK2XeZaSX
- Supply
- 1,000,000,000 (fixed)
- Mint authority
- Renounced
- In bonding curve
- ~99.96% (pump.fun)
- Treasury holds
- ~0.036% (locked)
What it is
- A community-owned memecoin with a fixed 1B supply
- Mint authority renounced — no new supply can ever be minted
- Community collectible status shown inside Wallet
What it is not
- Zero effect on game balance, drops, pricing, or progression
- No yield, no staking reward, no economic utility
- Funds development through trading fees — not by selling supply; the treasury's 0.036% stays locked
Phase 1 → Phase 2: trust, then code.
We start custodial and say so out loud, then replace custody with on-chain code as revenue funds it. Disclosing this is the trust asset — hiding it would be the rug-adjacent move.
The bond — honest custody
The in-game economy is closed-loop and off-chain. Phase 1 custody is plain and disclosed: buy-in value is held by the project, one-way, with no cash-out path. “The bond” is the design that custody follows — a one-way escrow whose redemption is authority-gated and never authorizes a cash-out — moving on-chain (as a program-derived account) as Phase 2 is built. Custody is in the company's hands today, and we disclose that plainly rather than pretend otherwise.
A game-locked Token-2022 mint
A new Token-2022 mint with a Transfer Hook extension (optionally Non-Transferable / Default-Frozen) so the in-game token is natively game-locked on-chain — replacing custody with code. Extensions are set at mint creation, so this has to be a new mint rather than a retrofit. It is revenue-bootstrapped: funded by trading activity, not a presale.
We frame the Phase 1 custody as a disclosed trust asset, not a hidden liability. Progressive decentralization means moving from “trust us, and here's exactly what we control” toward “the rules are enforced by code you can read.” On the record, in that order.
The things that never change.
These are commitments, not features. They constrain everything above.
Gold stays inside the game. Ownership does not.
Gold and credits are an off-chain soft currency: earned by playing, spent in the in-game marketplace, never converted into SOL, USDC, or withdrawable money. What you find is different. A discovered companion is property — sellable, tradeable, and yours to take with you.
Finding a companion is the money-in moment.
A player who finds a companion may launch a coin for it on pump.fun. The finder holds 25% of that supply. This is the primary way value enters a player's hands, and it starts with playing the game rather than with buying anything from us.
Launching a coin is optional, and the finder pays for it.
A companion is yours, and sellable, whether or not it ever has a coin. The launch is funded from the finder's own wallet and signed by the finder's own wallet — no studio key signs it, and declining costs nothing.
$MRDOPPLER never buys advantage.
The coin will never grant a mechanical edge, and appears only as collectible status inside Wallet. It funds development through trading fees; it does not and will not affect drops, pricing, balance, or progression.
The terms, defined.
The official vocabulary used throughout this document — in plain language.
- Closed-loop economy
- A currency system where value can enter and circulate but cannot leave. In-game gold is earned and spent in-game; it is never redeemable for real money.
- Off-chain ledger
- Balances tracked in the project's own database rather than on a public blockchain. Faster and free to transact, but custodial — you trust the operator's accounting.
- Custodial
- Held and controlled by the company on the player's behalf. In Phase 1, escrowed value sits in accounts the project controls — disclosed honestly rather than hidden.
- PDA (Program-Derived Account)
- A Solana account owned and controlled by a program rather than a private key. Used as an on-chain escrow whose movement is governed by code, not by a person holding keys.
- Authority-gated redemption
- Withdrawals from the escrow require a privileged authority to approve them. The Phase 1 bond is designed so that authority never authorizes a cash-out.
- One-way bridge / no off-ramp
- Value can move into the in-game economy but there is no path back out to real money. The bridge only flows one direction by design.
- Token-2022 / Token Extensions
- Solana's newer token standard that supports configurable extensions (extra rules) baked into a mint at creation time. Both project tokens are Token-2022 mints.
- Transfer Hook
- A Token-2022 extension that runs custom program logic on every transfer — used in Phase 2 to gate the in-game token on-chain so it can only move in approved ways.
- Non-Transferable
- A Token-2022 extension that locks a token to its holder — it cannot be sent at all. A candidate setting for a strictly in-game Phase 2 token.
- Default Frozen
- A Token-2022 extension where accounts start frozen and must be thawed by an authority before they can transact — another way to enforce game-locked behavior.
- Permanent Delegate
- A Token-2022 extension granting a fixed authority the ability to move or burn tokens — useful for enforcing in-game rules, disclosed as a trust assumption.
- Revoking mint authority
- Permanently giving up the ability to create new supply. $MRDOPPLER has done this — its mint authority is renounced on-chain, so no new supply can ever exist.
- Progressive decentralization
- Starting custodial and honest, then replacing trust with code over time as the project matures and is funded to do so.
- Revenue-bootstrapped
- Funded by trading activity and creator fees rather than by selling tokens up front. No presale, and no primary sale of companions.
- Settlement
- Trades settle in SOL or USDC. Outside the 2,500-companion founding mint, we never sell a companion — every trade is between players.
That's the whole picture.
