GameFi Weekly News Review — October 5–11, 2026
Across the nine chains we track, 1,056,200 people played on-chain games each day in the week of October 5–11, 2026 — a fourth straight weekly gain, up 0.3% from the week before. Below, every dated item is a real event from that window, linked to a mainstream outlet, the official announcement behind it, or the primary data source it is measured from. Where I add my own estimate, I say so.
The week in three numbers:
| Figure | What it says |
|---|---|
| 5.52 BTC | Stolen from Mezo's veBTC contract on October 5, across 37 positions and 36 wallets |
| Dec 15, 2026 | The date Abstract, Igloo's consumer L2, said it will shut down |
| $93.44B | USDT in circulation on TRON — 50.71% of all Tether dollars — as Polygon wired its payment stack to the chain |
Chains and network activity
The window's chain-level items: Ronin's Karst upgrade moved from scheduled to live, and TRON's payments role widened again as an outside payment stack plugged in.
Ronin's Karst upgrade goes live on mainnet
Karst activated on Ronin mainnet on October 7 at 16:00:01 UTC, exactly as scheduled on September 28. The upgrade brings Ethereum's Fusaka execution-layer improvements to Ronin, adds an L2 Contract Manager that can update the network's core contracts in a single block instead of routing through an Ethereum multisig, and lifts Ronin's L1 contracts to op-contracts v7.0.0. For players it was designed to be invisible: no action, no downtime. Builders face real changes — a new gas cap of roughly 16.8 million per transaction, P256VERIFY roughly twice as expensive, and a lower bn256Pairing limit of 300 pairs per call. Node operators had to migrate to op-reth v2.2.3 before activation; op-geth reached end of support and nodes left unupgraded stop following the chain.
Ronin is the largest economy in our table — 307,000 daily players — and Karst is the network's first upgrade since the May 12 move to an OP Stack layer 2. The fee line is untouched: Ronin still charges $0.0000 per game transaction, and the 16.8M gas cap sits far above a typical game move. The changes that matter are to cryptography pricing and to how fast the core contracts can be patched, not to what a player pays. I will re-price the moment anything lands in the fee column.
Polygon opens its payment stack to TRON, the chain holding half of all USDT
Polygon Labs announced on October 7 that Polygon Open Money Stack now supports TRON, giving fintechs, remittance providers and payment platforms a single integration to move bank funds into and out of the world's largest USDT (TRC-20) network. The stack connects regulated on-ramps to programmable TRON wallets and cross-chain routing. TRON's scale is the reason cited: according to Tether's own transparency page, $93.44 billion of USDT is in circulation on TRON — 50.71% of all Tether dollars across the 19 chains it reports. Polygon names the Philippines, Mexico, Argentina and Nigeria as target markets.
This is a payments story, not a fee story, and it is the clearest signal yet that TRON's role in GameFi is downstream of its role in stablecoins. Game payouts on TRON are priced in a chain whose liquidity comes from the dollar rails that just got a new front door. None of it changes the energy price or the $0.7388 rental median — but a deeper USDT base is what makes the TRON game-transaction route durable in the first place.
Games, launches and studios
The games table this week was defined by a shutdown and two launches — one a persistent world, one a milestone celebration.
Abstract, Igloo's consumer L2, will shut down on December 15
After weeks of speculation, Abstract — the consumer-focused Ethereum layer 2 backed by Pudgy Penguins parent Igloo — confirmed it is winding down and will shut down on December 15, 2026. More than 144 apps were deployed on the chain, which launched its mainnet in January 2025 and onboarded more than 400,000 users. Igloo funded Abstract for 18 months and, per CEO Luca Netz, lost tens of millions of dollars without finding product-market fit; the company considered launching a token or ICO and decided against it. Users must bridge assets off before the deadline or risk losing access.
A chain built around consumer brands and games — Abstract's pitch — is exactly the kind of surface our cost table is supposed to cover, and this is the reminder that chain survival is not a fee problem. Abstract's own numbers — 325 million transactions, $6 billion in DEX volume — did not produce a sustainable economy. For studios the lesson is custody and chain-risk, not gas: if your game's settlement layer can be switched off, the fee you pay on it was never the real cost.
Cambria starts minting 4,096 Founding Charter NFTs, still with no TGE date
The on-chain game Cambria began minting 4,096 Founding Charter NFTs on Ethereum as the first stage of Cambria Genesis, a persistent MMORPG that replaces the game's seasonal Gold Rush format. The 512 invitation-only Viceroy Charters started minting on October 7; the remaining 3,584 go to Founding Citizens on an allowlist. The project still has not published a token generation event date, and the Charters function as economic licenses needed to unlock full earnings in the new world rather than as collectibles.
The design worth watching is the one the mint avoids: a fixed, capped supply of entry licenses gating an economy, instead of an unbounded reward token. Whether it holds value depends on whether the persistent world produces more spend than the licenses cost to hold — the same sink-versus-source arithmetic that decides any play-to-earn payout. No fee line moves here; the token economics are the whole story.
Nine Chronicles marks six years with a 4 million NCG giveaway
Nine Chronicles marked its sixth anniversary on October 6 with a giveaway of more than 4,000,000 NCG to players over the following two months, the largest piece being 3.2 million NCG from Arena. The market read the announcement skeptically: at recent prices the whole pool is worth roughly $16,000–$18,000, and WNCG — the wrapped, tradable version of the in-game currency — has lost 9.0% over 90 days against a 28.2% gain for gaming tokens as a group. A planned October 20 update will add a Hard World 2 dungeon and permanent Collections and Titles.
A large headline number against a small token is the exact pattern this site prices. The NCG pool is spread across many players, and the currency that funds it has been losing value for months — so the real reward-per-hour fell before the anniversary and kept falling after. It is the same mechanism as an unlock week: the gas number never moves, but the payout behind a play session does.
Tokens, unlocks and in-game economy
The token side of the window was led by two supply events, both just inside the calendar.
Ethena's investor unlock closes a schedule, and HYPE's OTC release lands
Two supply events crossed the window. Ethena released its remaining investor allocation of roughly 1.41 billion ENA on October 5 — about 14.3% of circulating supply — a front-loading that closes the monthly investor tranches rather than adding net new issuance. Hyperliquid released about 3.75 million HYPE on October 6, roughly 1.69% of circulating supply and about $340 million, an OTC settlement some calendars record differently. Smaller releases followed through the week: KGEN's 57.75 million on October 7 (about 29% of its market cap), JTO's 11.31 million the same day, and STABLE's 888.8 million on October 8.
These are not GameFi fills, and I will not pretend they price a game transaction — none of the tokens touches a chain in our table. What the ENA event shows is how an unlock can be a restructuring rather than a dilution: pulling future tranches forward changes who can sell and when, without adding to the total. Studios paid in reward tokens should read the timing column first.
Security, policy and infrastructure
The security ledger of the window ran light on headline numbers and heavy on mechanism: one contract flaw, one governance takeover, and two small invariant breaks.
Mezo loses 5.52 BTC to a veBTC contract flaw, then pledges full reimbursement
An attacker exploited a flaw in Mezo's veBTC vote-escrow contract on October 5, moving 37 veBTC positions out of 36 holders' wallets and bridging roughly 5.52 BTC off the Mezo chain. The attack abused the interaction between the contract's trusted meta-transaction forwarder and its external libraries, letting the attacker impersonate the sender of a safeTransferFrom call and target unlocked-but-unredeemed positions so the proceeds could be redeemed and bridged out. After detecting the activity the next morning, Mezo paused bridge withdrawals about half an hour later, halted the chain, deployed a fix and re-enabled everything by 15:00 UTC on October 6. In an October 7 incident report the protocol said affected users will be reimbursed from protocol-owned funds.
This is the most instructive incident of the week for anyone building a game economy with a locking mechanism. The bug lived where two individually safe design choices met — a meta-transaction forwarder and code split into libraries to fit the contract size limit — and it escaped two audits and a bug bounty. If your game gates rewards behind vote-escrow or lock-up contracts, that intersection is where I would spend the next review hour.
Onyx DAO loses 620M XCN through its own governance
Security firm Blockaid flagged an exploit against the Onyx DAO treasury on Ethereum on October 6 in which 620 million XCN — about $2.91 million — moved from the treasury to attacker-linked wallets. The attacker passed a malicious governance proposal that authorized the transfer, clearing Onyx's proposal threshold, quorum requirement and a two-day timelock. It is the third governance or protocol failure for Onyx since 2023, when an earlier incident cost more than $3.8 million.
Guilds and game DAOs run the same machinery — proposals, quorums, timelocks — and treat the timelock as the safety net. Onyx's case shows the net only works if the voting power that clears quorum is itself distributed. For a play-to-earn guild treasury, concentrated voting power is a bigger balance-sheet risk than any single exploit; the fix is governance design, not a patch.
SlowMist flags BitBay and EtherVista as small edge-case breaks
SlowMist flagged two unrelated smart-contract exploits on October 9 totalling about $32,600. BitBay's DAI/USDC vault on Polygon lost roughly 14,838 DAI when its withdrawal function paid out the entire vault balance to a caller during a zero-liquidity state, instead of the caller's proportional share. About two hours later, EtherVista lost about $18,600 in WETH and its native token after an integer overflow in the swap function's invariant check let a crafted trade pass a safety test that should have blocked it.
Small losses, familiar weaknesses — and both are the kind of edge case that a game's own contracts can inherit if they fork a standard vault or AMM without re-testing the boundaries. The zero-liquidity branch and the uint112 multiplication ceiling are not exotic; they are the two places a rushed audit skips. Neither event moves a chain fee, and that is precisely the point: the gas number is not where the money leaves.
1WIN completes CertiK and Halborn audits ahead of its token launch
Crypto entertainment platform 1win said on October 8 that it completed independent smart-contract audits of its upcoming $1WIN token with CertiK and Halborn. CertiK reviewed 57 files across the token and sale/burn programs, logging 10 findings — seven resolved, two partially resolved, one acknowledged — with no critical or high-severity issues; Halborn reported four findings on the Solana programs, with the single medium-severity issue resolved. The token is an SPL asset designed for use across gaming, lottery and rewards.
An audit is a floor, not a guarantee — the Mezo incident four days earlier involved a contract that had passed two audits. What is worth copying here is the disclosure shape: findings counts, severity, and resolution status, published before launch rather than a single "audited" badge. Treat it as the minimum bar for any game token asking players to hold value in it.
Wallets, migration and user protection
One deadline and one milestone defined the user-facing side of the week.
Ronin's Waypoint wallet sunset nears, and the deadline already moved twice
Sky Mavis is switching off Ronin Waypoint — the keyless, social-login wallet used across Axie Infinity and other Ronin games — and anything still in a Waypoint wallet after October 16 may become unreachable. The migration does not run automatically. Players on email or social login must move assets to the new Ronin Stash wallet or to a seed-phrase wallet through Sky Mavis's own portals; seed-phrase users are unaffected. Pixels re-flagged the deadline to its stakers on October 6, and the cutoff has already moved twice: from September 16 to September 30 on August 18, then to October 16 on October 1.
Migration deadlines are the most reliable phishing window in crypto — the urgency is legitimate, which is exactly what makes fake portals work. The only safe routes are the official ones reached by typing the address, never by following a link. For studios, this is also a reminder that a keyless wallet is a dependency: when the provider sunsets it, your players' access goes with it.
Solana's active addresses hit a 13-month high
Unique active addresses on Solana reached 1.88 million as of October 9, the highest reading in 13 months, per data from SolanaFloor and the Blockworks analytics dashboard. Santiment reported the network's growth accelerated 124% since early September, roughly 1.71 million new wallets created per day, while daily active stablecoin addresses hit 888,000 in September — up 269% year over year. The one counter-signal: US spot SOL ETFs recorded net outflows of more than $22 million through early October.
Solana is the second-largest game economy in our table, and this is the activity side of the numbers we model — 209,400 daily players on a $0.00023 fee line. Unique addresses are a direction, not a measurement: new wallets and funded wallets measure different things, and address counts are famously inflated by airdrop and incentive farming. I read the stablecoin-address growth as the more durable signal, because moving dollars is not farmable.
The week's cost context
Every chain-level number below comes from the same week's measurement; the nine-chain table, persona monthly costs and the TRON route comparison are broken out in full in the cost update.
| Chain | Cost per game tx | GameFi DAU | DAU WoW |
|---|---|---|---|
| Ronin | $0.0000 | 307,000 | +0.3% |
| Immutable | $0.0000 | 141,700 | −0.4% |
| Solana | $0.00023 | 209,400 | +0.6% |
| Polygon | $0.0204 | 67,500 | −0.9% |
| Base | $0.0406 | 42,000 | +1.2% |
| Arbitrum | $0.0792 | 44,600 | +0.7% |
| BNB Chain | $0.0936 | 101,300 | +0.4% |
| TRON | $0.7388 | 118,000 | +1.4% |
| Ethereum | $2.9150 | 24,700 | −2.1% |
FAQ
Did the Karst upgrade change what a Ronin game transaction costs?
No. Ronin remains a $0.0000 fee line in our table. Karst changed client plumbing and cryptography pricing — P256VERIFY roughly doubled, bn256Pairing dropped to 300 pairs per call — and added a ~16.8M per-transaction gas cap that sits far above a typical game move. Players were told to take no action and there was no downtime.
Does Polygon's TRON integration change TRON game fees?
No. Polygon Open Money Stack connects banking rails to TRON USDT wallets and routing; it does not touch the energy market. The energy price (100 sun), the rental median (34 SUN) and the burn fallback ($2.1728) are all unchanged. What the integration deepens is the USDT base that the TRON game-transaction route settles against.
What should a studio take from the Mezo exploit?
That a contract can pass two audits and a bug bounty and still lose funds at the seam between two safe mechanisms. Mezo's flaw lived where a meta-transaction forwarder met library-split code; the attacker impersonated a transfer sender and drained expired lock-ups. Any game contract that gates rewards behind locking or proxies through a relayer has the same seam to check.
Is Abstract's shutdown a sign GameFi chains are failing?
It is a sign that a consumer-brand L2 without durable on-chain liquidity is failing, which is different. Abstract's own reported numbers — 325 million transactions, $6 billion in DEX volume — were not enough to justify the operating cost. Games on surviving chains in our table, including Ronin and Immutable, remain live and were unaffected.
Why does the weighted cost keep falling with no fee changes?
Mix. The nine-chain composite is transaction-weighted, and Ethereum — the $2.9150 chain — keeps losing share (down 2.5% on transactions this week) while sub-dollar chains gain. With every per-transaction price frozen for a fourth straight week, the weights alone moved the average from $0.0992 to $0.0987.
Which of the week's events touched a game economy directly?
Directly, none of the security incidents hit a major game on the nine chains we track. Mezo's loss was a DeFi lock-up contract, Onyx's was a DAO treasury, and the BitBay and EtherVista breaks were small DeFi pools. The event that touched players was Ronin's Waypoint wallet deadline — and that is a migration, not a fee.
