Overview: Trade as a Designed Experience

Player trading in Salt & Steel is not a neutral feature — it is a designed experience with explicit goals and explicit limits. Every decision in this system is a response to lessons learned from PoE's decade of trading evolution, from D3's catastrophic auction house, and from the specific demands of the pirate theme.

The fundamental trading position:

  • Item-to-item trading: Preserve friction. Social interaction, knowledge asymmetry, and the hunt for the right item are valuable. Frictionless item markets kill the item discovery experience.
  • Currency-to-currency trading: Automate it. The social value of negotiating 50 Doubloons vs. 1 Lodestone is zero. Currency exchange friction is pure waste — it taxes legitimate players more than the bots it supposedly deters.
  • The game never lies about what it is: Salt & Steel is a game where items are found and traded, and finding the right item is part of the experience. Players who want a guaranteed path to any specific item should build it through crafting or accept that the economy is the game.

The pirate theme provides a natural framework: pirates operated smuggler's networks, black markets, port-to-port trade, prize auctions, and information brokers. Salt & Steel's trade systems map onto this world not as forced metaphors but as authentic expressions of how trade worked in the age of sail.

Port Markets

What They Are

Port Markets are the primary player-to-player trading locations in Salt & Steel. Every major port town has a Port Market — a physically accessible in-game location where players can list items for sale, browse other players' listings, and complete transactions.

Port Markets are not abstract interfaces. They are locations in the world:

  • Nassau's Port Market occupies a section of the harbor boardwalk, with stalls and display cases visible to passing players
  • Tortuga's market is in the back rooms of a tavern — dirtier, darker, and slightly better prices on contraband
  • A Spanish colonial port's market is a formal trading house, decorated with imperial imagery, with guards at the entrance who check reputations

The Port Market's physical location in the world creates the moment of social presence that PoE's whisper system creates artificially. When two players trade in Port Royal's market, they are both physically there. The trade has a place.

Listing Items

How to list: A player brings items to any Port Market vendor (an NPC called a Factor) and specifies a price in Doubloons, Lodestones, or specific other currencies. The Factor records the listing. Listed items are removed from the player's inventory and held by the Factor.

Listing duration: Listings persist for 7 in-game days (approximately 7 real-world hours at average play density). Expired listings are returned to the player's Cargo Hold.

Geographic scope: Listings in Nassau are visible to all players browsing Nassau's Port Market. Listings in Tortuga are visible in Tortuga. A trade board system (see below) aggregates listings across ports for viewing but not for immediate transaction — the player must travel to the listing's port to complete the purchase.

Why geographic restrictions? Because travel is the game. A player who lists a rare item in Nassau is betting that Nassau's traffic will find it. A player who lists in a smaller port might get a better deal with less competition. Geographic spread preserves the living world — Port Markets are destinations, not a UI element.

Browsing and Buying

In-Port: At the Port Market, players browse an interface showing all items listed in that specific port. Items are searchable by type, modifier, rarity tier, and price range. The interface is in-game (not external).

Price: When a buyer finds a desired item, they pay the listed price directly to the Factor. No negotiation (listed price is fixed); no social friction for in-port transactions. The friction comes from traveling to the right port, not from the transaction itself.

Delivery: Items purchased are immediately available in the buyer's inventory. No physical handoff required — the Factor handles the logistics.

Trade Board (Cross-Port Aggregation)

What It Is

The Trade Board is Salt & Steel's in-game item search system that aggregates listings across all active Port Markets in a Voyage economy. It is accessible from any Port Market Factor, from the ship's captain's cabin, and from the player's personal Cargo Hold interface.

The key distinction from an Auction House: The Trade Board shows you what's available and where. It does not allow you to purchase remotely. Finding a Legendary Cutlass with perfect modifiers on the Trade Board tells you it's listed in Tortuga for 80 Doubloons. To buy it, you sail to Tortuga.

Why not just let people buy remotely? This is the designed friction point for item trading. The travel requirement serves several functions:

  1. It makes Port Markets destinations worth visiting — ports are alive with traffic because items are there
  2. It allows seller availability to matter — a seller who has logged off while listed can't sell to someone who arrived while they were away (the Factor handles the transaction, so actually seller presence isn't required, but buyer travel still requires commitment)
  3. It creates the pirate fantasy of going somewhere to find the thing you need

Trade Board Interface:

  • Filter by item type, rarity, modifier keywords, price range
  • Sort by price (low/high), listing age, distance from current port
  • See listing port location on the Nautical Chart
  • "Flag for Interest" — marks items you want to check when you pass through their port; notifications when new listings match saved searches

Price History: The Trade Board tracks historical transaction prices for common item types. Players can see that "T1 Physical Damage Cutlasses" traded for an average of 340 Doubloons over the last 7 days. This reduces information asymmetry for new players and eliminates the worst exploitation of knowledge gaps.

Community Development Note: PoE's reliance on poe.ninja and external trade sites is an acknowledged failure mode. The Trade Board is the designed solution to this — it provides the functionality players actually need (search, price discovery, watchlists) without requiring third-party tools or leaving the game. The baseline Trade Board is fully functional for all players. This is not a premium feature.

Smuggler's Network (Black Market)

What It Is

The Smuggler's Network is the black market trading layer — accessible only in pirate-friendly ports (Nassau, Tortuga, Madagascar) and only to players with sufficient faction standing with the Pirate Brotherhood.

What's traded here:

  • Cursed items: Items with Cursed modifiers (purple rarity) cannot be listed on standard Port Markets — colonial authorities confiscate them. The Smuggler's Network is the only venue for trading Cursed items.
  • Hot cargo: Stolen items from other players (PvP zone consequences), flagged as "Plundered" in their metadata. Standard Port Markets reject Plundered items.
  • Restricted materials: Salvage Materials from certain colonial wrecks are considered stolen property by the Spanish or British factions; trading them openly draws faction attention.
  • Information: The Smuggler's Network includes "Information Brokers" — NPCs who sell player-shared intelligence about rare chart locations, spawn patterns, and competitor captain positions.

Access requirement: Pirate Brotherhood Reaction Score of +2 or higher. Players who have built Honor reputation with colonial factions may have lowered Reaction Scores with the Brotherhood — they may not access the Network without reputation repair.

How it differs from Port Markets:

  • No public-facing Trade Board aggregation — you can only see listings in the physical Network location you're standing in
  • No price history (information asymmetry is part of the black market's character)
  • Shorter listing duration (3 days) — hot goods move fast
  • Higher Factor fees (12% vs. Port Market's 5%) — the smuggler's premium

Design Note: The Smuggler's Network exists because Cursed items are the most powerful items in the game and they need a trade venue. Making that venue slightly harder to access (faction requirement, limited to specific ports, no price history) preserves their mystique and maintains the pirate code's role in the economy. If you want to trade in the most powerful items in the world, you need to be trusted by the people who deal in them.

Currency Exchange (Automated)

What It Is

The Currency Exchange is a fully automated market for currency-to-currency trading. It operates like a real-time limit-order book: players post offers to trade one currency for another at a specified rate, and the system automatically matches compatible orders.

Access: Available at any port with a Port Market; also accessible from the ship's captain's cabin interface.

How it works:

  • A player posts an order: "Will trade 200 Doubloons for 1 Lodestone"
  • Another player posts: "Will trade 1 Lodestone for 190-200 Doubloons"
  • The system matches these orders automatically at the overlap point (200 Doubloons)
  • Both players receive their respective currencies instantly, without interaction

All currency pairs are supported: Any currency can be traded for any other currency. The most common pairs:

  • Doubloons ↔ Lodestones (the primary pair; mirrors USD/EUR in significance)
  • Doubloons ↔ Pieces of Eight
  • Doubloons ↔ Scrimshaw Tokens (bulk)
  • Steel Filings ↔ Compass Roses (bulk conversion pairs)

Price discovery: The Currency Exchange displays current order books (bid/ask at different quantities) and recent transaction rates. Market rates for major pairs are accurate to the second.

Why is this automated while item trading is not? Chris Wilson's framing applies directly: the social value of negotiating currency exchanges is zero. "I'll give you 200 Doubloons for a Lodestone" and "I'll give you 190 Doubloons for a Lodestone" is not an interesting social interaction — it's arbitrage. Automating it removes waste without removing anything worth keeping. Item trading, by contrast, involves knowledge, trust, and discovery — the social interaction has genuine value.

Anti-bot Design: The Currency Exchange is designed to be bot-resistant by having transparent pricing (bots cannot exploit price ignorance) and no meaningful first-mover advantage (orders clear at market rate, not at bot-selected advantageous rates). Real-money trading via the Currency Exchange is harder than via item trading because currency-to-currency rates are transparent and constantly competitive.

Auction House for Specific Cases

The full Auction House (remote purchase, no travel, instant settlement) is available for a limited and specific category of items: Nautical Chart Fragments.

Why Chart Fragments get an Auction House:

  • Chart Fragments are content-access keys, not power items
  • A player who needs Fragment 3 of the "Sunken Empire Chart" to play tonight's session should not be blocked by travel friction from acquiring a logistical prerequisite
  • Unlike gear items, Chart Fragments have standardized value (they're known quantity for known content); information asymmetry is minimal

The Auction House for Charts:

  • Lists only Chart Fragments (no gear items, no weapons, no accessories)
  • Remote purchase allowed — buy from anywhere, Fragment delivered to Cargo Hold
  • Fully automated; no travel required
  • Price history visible; market is transparent

This exception is deliberate and limited. It addresses the one area where travel friction creates genuine access harm (blocking content, not reducing power) without opening the general item economy to frictionless trading.

Player-to-Player Direct Trade

High-value item transactions often happen between players directly rather than through Port Markets. This is by design — Port Market Factor fees (5%) on a 2,000-Doubloon item are 100 Doubloons. Buyer and seller may prefer to meet, verify the item together, and exchange directly.

How direct trade works:

  1. Players initiate a Trade Request (UI) when in physical proximity (within trading range at a port)
  2. Both players see a trade window showing offered items/currencies from each side
  3. Both players confirm → trade executes atomically (either completes fully or not at all; no partial trades)
  4. Neither player can modify their offer after the other confirms (prevents trade-window bait-and-switch)

Social friction preserved: Direct trade requires physical co-presence at a port. The buyer and seller must both be in the same port at the same time. This maintains the social texture of high-value trading — it is a moment of player contact, however brief.

Reputation system integration: Players who repeatedly conduct unfair or deceptive trades (backing out at last moment, offering incorrect items) can be flagged by trade partners. Flags accumulate into a visible Trade Reputation score. Players with poor Trade Reputation find fewer willing trade partners in direct trades. This is a social accountability mechanism, not a mechanical punishment.

Crew Trade (Convenience Feature)

What It Is

Crew Trade allows players to delegate item listing and retrieval to a designated Crew Member rather than personally visiting a Port Market.

How it works:

  • Player assigns a crew member the "Trade Agent" role
  • Player specifies items to list (price and target port)
  • The Trade Agent carries items to the nearest port and lists them on the player's behalf
  • The Trade Agent returns with Doubloons (minus Factor fee) within 1-2 in-game hours
  • The Trade Agent can also retrieve sold-item proceeds when the player is at sea

What the Trade Agent cannot do:

  • Browse or purchase items for the player (agent handles selling only)
  • Make pricing decisions (player sets price)
  • Access the Smuggler's Network (Trade Agents are visible crew; contraband requires the player personally)

Limitations:

  • One Trade Agent per player (one crew member in this role at a time)
  • The crew member assigned as Trade Agent cannot perform their primary role while trading (a Gunner serving as Trade Agent is not at their cannon)
  • Trade Agents occasionally make errors in competitive pricing environments (5% chance per transaction of miscommunicating price, resulting in 10% discount to buyer — minor, not game-breaking)

Why this exists: Solo players or players with limited play-time windows should not be locked out of the economy because they cannot personally visit Port Markets during prime hours. The Trade Agent provides convenience that respects that constraint. It does not provide competitive advantage over players who engage personally — it provides approximate parity with lower friction.

Is this the stash tab equivalent? Partially. The Trade Agent reduces logistical burden but does not increase item power or crafting effectiveness. It is a quality-of-life feature with a meaningful in-world expression (the crew member physically doing the work).

Solo Self-Found Mode (SSF)

What It Is

Solo Self-Found mode is an opt-in character mode selected at character creation. SSF characters:

  • Cannot trade with other players (items and currencies are Account-bound while on this character)
  • Cannot receive items or currencies from other players (no drops passed from other characters, no gifting)
  • Play in the same world as trading characters (shared ports, shared seas) but with economic isolation

Why it exists: Some players do not want to engage with the trading economy. They find the experience of finding their own gear more satisfying than finding the right gear. SSF respects this preference and ensures the game is completeable on this basis.

Is SSF the same as PoE's SSF? Approximately. The same philosophical commitment: all content is accessible in SSF (no content is trade-gated), and SSF is a legitimate way to play the full game.

Compensation: SSF characters receive a 20% increase in rare item drop rate and a 25% increase in currency drop rate. This partially compensates for the loss of trade amplification — in trading economies, crafting currency acquired by players who don't need it flows to those who do; SSF players can't access that flow.

Voyage Leaderboards: SSF has dedicated leaderboard rankings. First SSF Captain to complete specific endgame milestones is a separate competitive category from the main trading-economy leaderboard.

Voyage Economy vs. Standard Economy

The Two Economies

Salt & Steel operates two parallel economies at all times:

Voyage Economy: Fresh-start economy that resets with each Voyage (approximately every 16 weeks). Characters who participate in the Voyage economy cannot trade with Standard economy characters. All competitive play, fresh economy racing, and economy-focused early-league activity occurs here. This is the "live" economy — the one that matters to current-season players.

Standard Economy: The persistent economy where characters migrate after their Voyage ends. Standard characters retain their gear and currencies but join an economy that has been accumulating for the entire game's lifetime. Standard is secondary: its economy is inflated relative to Voyage (much more currency exists), prices are higher in nominal terms, and new players who arrive in Standard find competition from entrenched currency holders.

What resets and what doesn't:

  • Voyage Economy reset: complete economic reset, all prices start from zero, all market listings cleared
  • Character identity NOT reset: Account Record persists (name, reputation history, Voyage achievements, cosmetics)
  • Functional character progression resets: Skill Atlas purchases, item collection, currency holdings all reset to zero at Voyage start

Why two economies? The Voyage reset is Salt & Steel's answer to PoE's fresh-start league model — but better calibrated. The Standard economy exists so that characters who don't want to restart every 16 weeks have somewhere to go. But Standard is honestly secondary: it is "where characters go when Voyages end," not where the competitive game is played.

Economic Fresh Starts as a Feature

The Voyage economy's fresh start is not a penalty — it is the product. Each Voyage economy starts with everyone at zero. The first week of a Voyage economy is when competition for early items, early crafting, and early endgame content is most intense and most rewarding. The economy is cleanest; discoveries are most impactful; being first to something matters most.

Players who arrive late to a Voyage or who have time-constrained play may not participate in the early economy race. This is acknowledged — it is the trade-off of the fresh-start model. Salt & Steel's response: Voyage Supporter Packs (cosmetic rewards for supporting the game during a Voyage) provide aesthetic participation for players who cannot compete at the top of the economy ladder.
