Crafting

Crafting is the SAGE production loop that turns input cargo into output cargo through recipes, starbases, crew, timers, fees, and optional crafting habs.

Recipes define what can be made, crafting habs modify and unlock work, and crafting processes track active jobs.

Star Atlas KB material frames resources as inputs for crafting and starbase work. In SAGE C4, that becomes an on-chain workflow: read a recipe, verify starbase/player/cargo/crew context, create a crafting process, wait for it to mature, then complete or cancel it.

Read crafting as part of the active economy, not a standalone manufacturing screen. Crafted outputs can support starbase upgrades, infrastructure contracts, trading, upkeep, and other player-driven loops.

Developer use

Use this page when you need to:

• display recipe inputs, outputs, status, duration, fees, and requirements
• inspect a player's crafting hab infrastructure
• start, complete, cancel, or destroy crafting processes
• explain crew, cargo, ATLAS, rent, and starbase-player effects before signing

Technical model

Crafting has three layers: Recipe for configuration, CraftingHabInstance for player infrastructure, and CraftingProcess for a specific job. The write path commonly validates Player Profile, reads Game and StarSystem, writes Character and StarbasePlayer, and creates or mutates a CraftingProcess.

PTR traces show startCraftingProcess creating a signer/writable crafting-process account and using the SAGE program address as a sentinel for absent optional accounts. Transaction summaries should call out both details.

Generated anchors

Crafting account and instruction helpers live in @staratlas/dev-sage.

import {
	fetchMaybeCraftingHabInstance,
	fetchMaybeCraftingProcess,
	fetchMaybeRecipe,
	findRecipePda,
	getStartCraftingProcessInstructionAsync,
	RecipeStatus
} from '@staratlas/dev-sage';

Accounts and types

Generated symbol	Kind	Beginner meaning
Recipe	account	A recipe definition: inputs, outputs, duration, fees, status, limits, and requirements.
CraftingHabInstance	account	A placed crafting hab owned by a player. It can unlock recipes and apply crafting modifiers.
CraftingProcess	account	One active or completed crafting job for a profile, starbase player, recipe, and hab context.
RecipeStatus	enum	Whether a recipe is Active or Deactivated.
StructureInstanceState	union	Whether a crafting hab is Active, in Design, or Deactivated.

Read this as three layers:

• Recipe is static-ish game configuration for what can be crafted.
• CraftingHabInstance is player-owned production infrastructure.
• CraftingProcess is the time-bound job created when crafting starts.

PDA helper

Only Recipe has a generated PDA helper.

Helper	Seeds	Meaning
findRecipePda	gameId, recipeId	Find the definition account for a recipe in one SAGE game.

import { findRecipePda } from '@staratlas/dev-sage';

const [recipeAddress] = await findRecipePda({
	gameId: gameAddress,
	recipeId
});

CraftingHabInstance and CraftingProcess do not expose generated PDA helpers in the current package; read them by known account address unless a higher-level indexer or UI gives you the derivation.

Read a recipe

This example reads a recipe by PDA. It does not sign or send a transaction.

import { address, createSolanaRpc } from '@solana/kit';
import {
	fetchMaybeRecipe,
	findRecipePda,
	RecipeStatus,
	StarbaseLevel
} from '@staratlas/dev-sage';

const rpc = createSolanaRpc('https://testnet-rpc.z.ink');
const gameAddress = address('GAME_ADDRESS_HERE');
const recipeId = /* RecipeId value from config or UI */;

const [recipeAddress] = await findRecipePda({ gameId: gameAddress, recipeId });
const recipe = await fetchMaybeRecipe(rpc, recipeAddress, {
	commitment: 'confirmed'
});

if (!recipe.exists) {
	throw new Error(`Recipe not found: ${recipeAddress}`);
}

console.log({
	name: recipe.data.name,
	status: RecipeStatus[recipe.data.status],
	minStarbaseLevel: StarbaseLevel[recipe.data.minStarbaseLevel],
	craftingDuration: recipe.data.craftingDuration,
	inputs: recipe.data.inputs,
	outputs: recipe.data.outputs
});

Read a crafting process

This example reads a process by address.

import { address } from '@solana/kit';
import { fetchMaybeCraftingProcess } from '@staratlas/dev-sage';

const craftingProcessAddress = address('CRAFTING_PROCESS_ADDRESS_HERE');
const process = await fetchMaybeCraftingProcess(rpc, craftingProcessAddress, {
	commitment: 'confirmed'
});

if (process.exists) {
	console.log({
		recipe: process.data.recipe,
		profile: process.data.profile,
		quantity: process.data.quantity,
		numCrew: process.data.numCrew,
		startTime: process.data.startTime,
		endTime: process.data.endTime
	});
}

Instruction families

Crafting-related instruction builders fall into several groups.

Family	Instructions	What they manage
Recipe admin	createRecipe, updateRecipe, deactivateRecipe	Create, change, or deactivate recipe definitions.
Crafting process	startCraftingProcess, completeCraftingProcess, cancelCraftingProcess, destroyCraftingProcess	Start, finish, cancel, or close crafting jobs.
Crafting hab lifecycle	placeCraftingHabInstance, deconstructCraftingHabInstance, evictCraftingHabInstance, respawnCraftingHabInstance, completeCraftingHabRespawn	Place, remove, evict, or respawn crafting hab instances.
Hab buildings	placeCraftingHabBuildings, finalizeHabBuildingChanges, cancelHabBuildingDesign	Design and finalize building changes for a crafting hab.
Rent	payCraftingHabRent, craftingHabRentTopUp	Collect or add rent balance for hab infrastructure.
Resource loop	craftingHabResourceConsumption, craftingHabResourceSwap	Consume or swap resources through hab production state.
Runtime config	updateCraftingHabDefinition, updateCraftingHabRuntimeConfig	Update hab definitions and runtime config.

Many crafting instructions validate the Player Profile and may write profile, starbase-player, recipe, hab, process, cargo, or currency-cache accounts.

Instruction example: start crafting

This example builds a startCraftingProcess instruction for review.

For the full read/build/review/simulate path, see Crafting Process Workflow.

import { getStartCraftingProcessInstructionAsync } from '@staratlas/dev-sage';

// These values must come from wallet/profile state, recipe discovery,
// starbase-player state, and cargo availability.
const instruction = await getStartCraftingProcessInstructionAsync({
	profileValidationSigner: signer,
	profileValidationProfile: profileAddress,
	character: characterAddress,
	game: gameAddress,
	system: starSystemAddress,
	starbasePlayer: starbasePlayerAddress,
	recipe: recipeAddress,
	craftingProcess: craftingProcessSigner,
	craftingHabInstance: craftingHabAddress,
	crewBinding: crewBindingAddress,
	keyIndex: 0,
	quantity: 1n,
	numCrew: 1
});

console.log(instruction.programAddress);

Before sending a crafting transaction, show:

• which wallet signs
• which Player Profile key index authorizes the action
• which recipe is used and whether it is active
• which input cargo is consumed
• which output cargo will be produced
• which starbase player and crafting hab accounts become writable
• whether a crew binding is selected for the job
• whether fees, crew, rent, or usage limits change
• what simulation returns

Safety notes

Reading crafting accounts is safe. Sending crafting instructions can lock cargo, consume resources, change rent state, alter usage counts, or mutate player-owned infrastructure.

Do not use send examples until PTR behavior has been verified with a transaction simulation and a before/after account diff.
