Deeds and the Fert Deck

The Founding Deeds are the land of Yield Fields: 3,333 NFTs on Robinhood Chain. Each Deed has a rarity, a biome and a Fertility from 5 to 9. Fertility is the number that matters: it sets how much Fertilizer the Deed makes and its share of the Root Cellar now, and later its share of Deed rewards and the Windfall.

A Deed does nothing in a wallet. Staked and given a Fert Deck, it makes Fertilizer around the clock. Staking is free; the deck costs 0.01 ETH, and that fee goes into the Deeds’ shared backing, the Root Cellar (see What a Deed earns). This has been live on mainnet since 3 November 2026, 13:06 UTC. Verified

The five tiers

Each card shows the tier’s supply, Fertility, Fertilizer per day (F/2), the deck’s storage (3 days), its Root Cellar value (live from the game) and its Windfall share. Verified

Every Deed of a rarity has the same Fertility. A Mythic has 1.8× the Fertility of a Common (9 against 5). Rarity was assigned at random and is in the metadata. Official source

Fertility is onchain

The Fertility of every Deed is stored onchain on Robinhood Chain. All 3,333 values were set on 1 November 2026, and the table is locked as complete. Verified

The game’s total Fertility reads 19,773, exactly the sum of the table. This is the number every share is divided by: a Deed’s share of the Root Cellar is F / 19,773. A Common holds 0.02529 % of the backing, a Mythic 0.04552 %. Verified

The Deed panel in the game shows the same thing as “Backing weight: 9 pts · 1.8× Common” for a Mythic.

What Fertility does

The docs list one more Fertility use as “(classified)” and add that “more parts of the game may use Fertility as it grows”. Official source The later uses are on What a Deed earns.

The NFT

Royalty: 5 % on resale (the docs say it goes to the project treasury). Official source

The art

Each Deed is animated isometric pixel art, 180×180, laid out on a 4×4 grid. The top of the plot is the build site, drawn empty; the game draws the structure there. Terrain is generated as an Open Field, Pond or River, with big decor, water decor and small decor; rarer Deeds roll more decor and specials, and a special never repeats on the same plot. The art is visual only.

When a Deed’s Fert Deck is producing, the game shows the Deed with the deck drawn on its build site.

Staking today

Fert Decks built so far counts rebuilds too: some Deeds were unstaked, restaked and built again. Verified The network’s output at full speed is shown live on The network brake.

How to stake and build

The build fee is a setting the team can change; the docs call it “0.01 ETH at launch”. May change A fee of 0 would mean building is closed (“Fert Deck building isn’t open yet”). Verified

Each staked Deed holds one structure. The Fert Deck is the first; more types are planned. Structures are not part of the NFT. Official source

What a deck makes

A Fert Deck makes half a Fertilizer a day per Fertility point and stores up to 3 days of it.

The game counts in small units: one Fertilizer is 172,800 units, and a deck gains F units a second at full speed. That gives the times in the last column: a Common needs 172,800 ÷ 5 = 34,560 seconds (9.6 h) per Fertilizer. Verified

The Fertilizer in a deck is kept by the game, off chain. Only the stake and the build are onchain; the deck starts counting from the moment it is built. Verified

Speed

A deck runs at full speed unless one of two brakes is on: the network rate (all decks slow when more than 7 days of output sits unused) or your export rate (your decks slow when you export more than a quarter of their daily output). A deck runs at the slower of the two, never below half speed. On 8 November the network rate was 100 %. Verified Both brakes are explained on The network brake.

Full means stopped

The screen shows “Full. Claim to restart production.” and “Claim to resume”. Verified Progress toward the next Fertilizer carries over between claims.

Deck states

The Deed list groups rows as “Producing”, “Idle · no Fert Deck”, “Idle · not staked” and “Ended decks”, with full decks first. Verified

Who owns the stored Fertilizer

Fertilizer stored in a deck belongs to whoever built the deck, not to whoever owns the Deed now.

• A deck is identified by its build, not by the Deed. If the Deed leaves your wallet, its deck stays in your list as ended: “You built this Fert Deck; the deed has left your wallet.” “What the deck stored stays yours to claim.” Verified
• So selling a Deed does not sell its stored Fertilizer, and the buyer starts with an empty deck and a new 0.01 ETH build. Inferred

The fraction is lost

When a deck ends, its whole Fertilizer is credited and the fraction toward the next one is lost: “its stored whole Fertilizer … the fraction toward the next one is lost.”

Example. A Common deck that has stored 4.9 Fertilizer is unstaked: 4 are credited, and the 0.9 is gone. Claiming first does not help, since a claim also takes only whole units; unstaking just after a whole unit is reached loses the least. Inferred

Unstaking

Can you unstake while the game is paused? Yes: unstaking stays open during a pause, and every other action waits. Verified

Batch limits

Up to 500 Deeds per transaction in the game. When a selection is too big: “picked: the most one transaction carries. Pick the rest in another.” Verified

Still REDACTED

• The Fertility use the docs list as “(classified)”.
• The structures planned after the Fert Deck, and their fees.
