Resources & crafting

The Season 0 economy is deliberately small enough that players immediately understand it. All resources are off-chain: they have no external monetary value and cannot be withdrawn to a wallet.

Raw resources

Resource	Source	Basic timer
Grass	Meadow	5 minutes
Water	Well	10 minutes
Wool	Fed alpaca	20 minutes
Wood	Timber grove	15 minutes
Stone	Quarry	20 minutes

Crafted resources

Item	Recipe	Crafting time
Feed	3 Grass + 1 Water	2 minutes
Planks	3 Wood	5 minutes
Rope	4 Wool + 1 Water	10 minutes
Bricks	3 Stone + 1 Water	10 minutes
Wheel	5 Planks + 2 Water	15 minutes
Alpaca Cart	4 Wheels + 10 Planks + 2 Rope	60 minutes

Exact resource costs may be rebalanced after playtesting, but the time sequence should remain predictable.

Where crafting runs

Crafting does not require a custom Solana program. Resources live in MongoDB and the Rust backend is the authoritative crafting engine:

ALPUN   = tradable on-chain SPL token
GRASS  = off-chain game resource
WATER  = off-chain game resource
WOOD   = off-chain game resource
...

Every craft is validated server-side (inputs present, station built, timer elapsed) and recorded in the inventory ledger with an idempotency key, so a craft can never be credited twice.

Rare crafting achievements

Ordinary carts stay in MongoDB. Completing a notable crafting chain can create an NFT reward entitlement instead — for example the Golden Alpaca Cart tier of the Season 0 collection:

Ordinary crafting chain      → cart in MongoDB
Rare crafting achievement    → Golden Alpaca Cart NFT (on-chain)
