Open Firefly

Firefly is Mask Network's Web3 social app for iPhone and iPad, built for cross-posting across X, Farcaster and Lens, and it also carries a Polymarket builder code ranked #49 by attributed volume. It suits traders already living in Mask's social feed, not anyone seeking a dedicated trading terminal, and the decision comes down to Firefly's undisclosed fee structure.

What it is

Firefly, styled by its developer Mask Network as a Web3 Everything App, is a social feed for iPhone and iPad that pulls X, Farcaster, Lens, Mirror, Gitcoin and Snapshot into one timeline. Its stated purpose is discovery: alpha on product launches, free NFT drops surfaced in a dedicated feed, and community proposals tracked through Snapshot voting. Cross-posting lets a user publish once and reach followers on every connected network, and the app carries its own wallet for sending onchain transactions, though a recent reviewer flagged that wallet as inconsistent when broadcasting transactions.

On Predicts.guru, Firefly is curated under Copy Trading and carries a verified Polymarket profile, sitting at rank #49 by all-time attributed volume of $11.2M. Its order flow has run since 2026-04-23, most recently concentrated in dota2 markets such as Will Team Resilience Win The International 2026, with figures current through 2026-09-14.

How it works

A trader reaches Firefly by installing it from the App Store onto an iPhone or iPad; the operator does not list an Android build or a browser version. Inside the app, the same wallet that broadcasts onchain transactions for NFT collecting and Snapshot voting is what carries a trade into Polymarket, and every order tagged with Firefly's builder code lands on Polymarket's central limit order book alongside every other builder, with only the code on the fill distinguishing it.

The operator's own listing does not spell out custody or key management for that wallet, and one reviewer described it as inconsistent when sending transactions, a detail worth weighing before routing size through it. Firefly's core pitch, per its App Store page, is aggregation rather than trading: pulling X, Farcaster, Lens, Mirror, Gitcoin and Snapshot into a single feed alongside an NFT drop feed, with the wallet functioning as the connective piece rather than a dedicated order ticket.

What it does

  • Cross-network social posting

    A single post pushes to X, Farcaster and Lens at once, letting a trader keep one voice across networks instead of manually duplicating updates on each app.

  • NFT drop feed

    A dedicated feed surfaces trending and free NFT mints, useful for spotting collectible activity without a separate marketplace app open.

  • Snapshot vote tracking

    Community proposals and votes across Snapshot are tracked in one place, letting a user follow DAO governance without visiting each project's own site.

  • Built-in transaction wallet

    Transactions send from a wallet built into the app itself, though a recent reviewer reported it is inconsistent when broadcasting, a real reliability cost.

Who it is for

Web3 social power user
Someone already cross-posting to X, Farcaster and Lens gets one feed and one wallet instead of juggling three separate apps and timelines.
NFT drop hunter
A collector watching for free mints and trending NFT activity gets a dedicated feed built for exactly that, without a marketplace subscription.
DAO governance follower
A trader who tracks proposals and votes across multiple DAOs can follow Snapshot activity for several projects in a single timeline.
Occasional Polymarket copy trader
A trader already inside Firefly's ecosystem who routes a Polymarket position through its wallet avoids installing a separate trading app, at the cost of an unpublished fee.
Trader wary of unproven venues
Someone who weighs 145 days of history and a cohort of 110 wallets before committing size can use those figures to judge whether Firefly's flow looks seasoned enough yet.

What it costs

Firefly's own App Store listing says nothing about trading fees; its description covers social feeds, NFT drops and governance tracking, not a schedule for order routing. The operator does not state a rate anywhere in its own material, so the curated fee field carries no published figure. Polymarket's own trading fee is fixed per market and identical no matter which builder carries the order, so it says nothing about Firefly specifically. Before routing size through Firefly, the wallet's reliability deserves more attention than any fee line, since one reviewer already flagged inconsistent transaction broadcasting.

Strengths

  • Runs inside a mobile app already used for X, Farcaster and Lens, so a trader already living there adds Polymarket exposure without a new install.
  • Tracks Snapshot governance and NFT drops alongside trading, useful for a trader who follows onchain activity broadly rather than just one market.
  • Carries a verified Polymarket profile and a measurable track record stretching back 145 days, giving a baseline to judge before committing funds.
  • Cross-posts a single update to every connected network, saving time for a trader who also runs a public presence.

Limitations

  • Publishes no fee schedule at all, leaving a trader to discover the cost of routing an order only after it fills.
  • A recent reviewer reported the built-in wallet is inconsistent when broadcasting transactions, a direct risk to anyone sending a trade through it.
  • Its own product description is built around social feeds and NFT discovery, not trading, so Polymarket order flow reads as a secondary function bolted onto a social app.
  • Available only on iPhone and iPad per its own listing, closing it off to a trader on desktop or Android.

Custody and transparency

Firefly's wallet sends onchain transactions directly from the app, and the operator's own listing gives no detail on how keys are stored or recovered. That silence matters more given a recent review describing the wallet as unreliable when broadcasting, since a failed or duplicated transaction during a Polymarket order is an operational risk distinct from any market risk. The app carries a verified Polymarket profile and discloses its attributed volume, fill count and history openly, but nothing in its own material addresses custody model, insurance or what happens to funds if the app itself has an outage.

Verdict

Firefly reads first as Mask Network's social aggregator for X, Farcaster and Lens, with Polymarket order flow riding on the same wallet that handles NFT collecting and Snapshot votes. That dual identity is the whole story: a trader gets convenience if they already live inside Firefly's feed, and gets an unpublished fee plus a wallet a reviewer called unreliable if they do not. Rank #49 and 145 days of history give some track record to lean on. Anyone already using Firefly for its social features can reasonably route a small Polymarket position through it; anyone shopping purely for a trading venue should look elsewhere first.

How these numbers are measured

Polymarket reports $11.2M of all-time volume for Firefly, including attribution from before onchain V2. The indexed figure used for fees, fill sizes, and buy/sell split is $9.6M, counted as outcome-share par notional on CLOB V2 only, so the two totals differ by design.

58.8% of attributed volume is buy-side, which indicates whether the venue is used mainly to open positions or to exit them.
