Character and Progression

Character and progression accounts connect a Player Profile to SAGE-specific state: check-ins, XP, research, crew counts, ship/cargo counts, modifiers, and ATLAS accounting.

Player Profile and Profile Faction establish identity and faction. SAGE adds game-specific progression on top of that foundation.

In Star Atlas terms, Character is the game-specific layer of a player profile: the account that lets SAGE track progression, daily check-ins, XP, modifiers, and counts that are separate from the generic identity model.

SAGE rewards progression through activity. Experience, loyalty, and ATLAS reward flows can involve combat encounters, repairing or upgrading friendly starbases, and attacking enemy infrastructure. Character is one of the accounts where that activity becomes player-specific state.

Position in the account hierarchy

Owned by: SAGE program through @staratlas/dev-sage
Derived from: Player Profile + Game
Meaning: the profile's game-specific progression and accounting state
Downstream: helps derive StarbasePlayer and participates in fleet, cargo, crafting, claim-stake, crew, research, and reward instructions

Character is not the wallet and not the generic Player Profile. It is the bridge between Star Atlas identity and one SAGE game instance.

Developer use

Use this page when you need to:

• derive a SAGE character from a player profile and game
• display XP, check-in, modifier, or asset-count state
• explain why a fleet, mining, crafting, starbase, or claim-stake instruction also writes character state
• prepare daily check-in or research-related transaction reviews

Technical model

Character is a PDA derived from playerProfile and gameId. It is not the wallet and not the Player Profile account, but many SAGE instructions write it because gameplay changes progression, counts, crew, or accounting state.

PTR traces confirm this relationship: fleet cargo, mining, crafting, claim-stake, and disband flows often write Character alongside the main domain account.

Generated anchors

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

Accounts and types

Generated symbol	Kind	Beginner meaning
Character	account	SAGE-specific player state for one profile in one game.
CheckInStreakInfo	type	Daily check-in streak data nested in Character.
XpInfo	type	XP state nested in Character.
CharacterAssetCounts	type	Counts of assets associated with the character.
CharacterModifiers	type	Active modifiers applied to the character.
ResearchNode	type	Research-tree node definition.
ResearchTreeDefinitions	type	Research tree definitions nested in Game.
DailyCheckInConfig	type	Daily check-in tuning nested in game/XP config.

Character account

Important fields:

playerProfile       Player Profile account
gameId              SAGE game account
bump                PDA bump
checkInInfo         daily check-in streak state
xpInfo              XP state
atlas               ATLAS accounting value
counts              character asset counts
pilotXpBudget       pilot XP budget/accounting state
characterModifiers  active modifiers

Character is derived from a profile and game. Many SAGE instructions can derive it automatically when given profileValidationProfile and game, but application code should still understand what account is being touched.

PDA helper

Helper	Seeds	Meaning
findCharacterPda	playerProfile, gameId	Find a SAGE character for one player profile in one game.

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

const [characterAddress] = await findCharacterPda({
	playerProfile: profileAddress,
	gameId: gameAddress
});

Read a character

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

import { createSolanaRpc } from '@solana/kit';
import {
	fetchMaybeCharacter,
	findCharacterPda
} from '@staratlas/dev-sage';

const rpc = createSolanaRpc('https://testnet-rpc.z.ink');

const [characterAddress] = await findCharacterPda({
	playerProfile: profileAddress,
	gameId: gameAddress
});

const character = await fetchMaybeCharacter(rpc, characterAddress, {
	commitment: 'confirmed'
});

if (!character.exists) {
	throw new Error(`Character not found: ${characterAddress}`);
}

console.log({
	profile: character.data.playerProfile,
	gameId: character.data.gameId,
	atlas: character.data.atlas,
	checkInInfo: character.data.checkInInfo,
	xpInfo: character.data.xpInfo
});

Instruction families

Family	Instructions	What they manage
Character setup	registerCharacter	Create or initialize SAGE character state for a profile/game.
Crew movement	addCrewToGame, removeCrewFromGame, devAddCrew	Add or remove crew from SAGE game state.
Crew progression	awardCrewActivityXp, levelUpCrew, migrateCrewMember, markCrewGarrison, mintNpcCrewCapacity	Update crew XP, levels, migration state, garrison state, or NPC capacity.
Daily check-in	dailyCheckIn	Mutate check-in streak/progression state.
XP config	updateXpCheckInConfig, updateXpThresholds	Admin/configuration for check-in and XP thresholds.
Reward and loyalty accounting	claimLoyaltyAtlas, settleLoyaltyContribution, sweepExpiredLoyaltyAtlasBank, advanceAtlasRewardEpoch, rollAtlasRewardEpoch	Claim or settle loyalty and ATLAS reward state.
Research	updateResearchTreeNodes, unlockResearchNode	Manage research definitions and unlock player research.
Rentals	addRental, changeRental, invalidateRental	Manage rental-like progression/accounting state.

Instruction example: daily check-in

This example builds a dailyCheckIn instruction for review. It still needs transaction summary and simulation before a wallet prompt.

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

// These values must come from wallet/profile state and SAGE character discovery.
const instruction = await getDailyCheckInInstructionAsync({
	profileValidationSigner: signer,
	profileValidationProfile: profileAddress,
	game: gameAddress,
	character: characterAddress,
	keyIndex: 0,
	restoreStreak: false,
	expectedRestoreCost: 0n
});

console.log(instruction.programAddress);

Before sending a progression transaction, show:

• which wallet signs
• which Player Profile key index authorizes the action
• which character account changes
• whether XP, streak, ATLAS, research, crew, or modifiers change
• which accounts become writable
• what simulation returns

Safety notes

Reading character and progression state is safe. Sending progression instructions can change player state, unlock research, change crew counts, or mutate reward/accounting values.

Keep user-facing flows explicit about account effects. Progression state looks harmless until it changes shared strategic limits or reward eligibility.
