9 perp house vaults listed for Japan
In ChainChoice’s published ranking order, from this category’s 9 providers: those whose terms exclude Japan are removed; naming Japan or a region that covers it counts the same, and those whose terms do not state it come last. Each chip names the basis: a dated check, a region listing, or the provider's own claim.
#1 for JapanGMX GM / GLV pools#1 globallyProvider states broad availability Risk-isolated per-market house vaults where the LP is the traders' counterparty, protected by a named automatic on-chain deleveraging rule (MAX_PNL_FACTOR_FOR_ADL) rather than a human vote, with a full-life realised-PnL series retrievable keylessly but only by assembling it yourself.
Pool protection mechanism — 9/10Fee versus pnl honesty — 9/10Verifiable loss of record — 8/10#2 for JapanAvantis avUSDC#2 globallyLists Asia; Japan not individually verified Single ERC-4626 USDC vault on Base that is the counterparty to every Avantis perp trade, protected by a published per-trade profit cap of 2500% of collateral and a solvency-indexed withdrawal-fee schedule.
Pool protection mechanism — 9/10Loss waterfall and exit price — 9/10#3 for JapanOstium OLP#3 globallyLists Asia; Japan not individually verified The pool's only documented junior tranche — and, post-upgrade, barely a house vault: OLP now earns opening fees only, with the real counterparty an offchain Jump Trading mirror hedge. Its loss record can be rebuilt from a keyless Ostium subgraph the docs never point depositors at, but it prices OLP only at settlement, so it showed no loss for 60 days after the July 2026 vault drain, until a 69.2% write-down on 12 September 2026; the operator's own pages mention neither.
Pool protection mechanism — 8/10Fee versus pnl honesty — 8/10#4 for JapanVelocity Insurance Fund#4 globallyProvider states broad availability Solana perp DEX's staker-owned first-loss backstop: you are the equity tranche that pays trader bankruptcies, behind a 13-day cooldown whose payout can only be revised downward.
Pool protection mechanism — 8/10Fee versus pnl honesty — 6/10#5 for JapangTrade gToken Vaults (gDAI / gUSDC)#5 globallyLists Asia; Japan not individually verified The longest-running pure house vault: ERC-4626 gToken shares whose price is literally 1 + cumulative fees - cumulative trader PnL, both accumulators readable free onchain, with a withdraw lock that lengthens to 3 epochs exactly as the collateralization ratio falls - and gUSDC read 97.83% on 28 September 2026.
Pool protection mechanism — 7/10Verifiable loss of record — 6/10#6 for JapanJupiter JLP#6 globallyLists Asia; Japan not individually verified The largest house vault in existence: a single-pot, no-tranche Solana pool that is the direct counterparty to traders on the SOL, ETH and wBTC markets of Jupiter Perps (its Beta markets run on a separate engine), uniquely honest about what its advertised APY leaves out and almost entirely silent about what stops a winning trader.
Fee versus pnl honesty — 9/10Verifiable loss of record — 6/10#7 for JapanHyperliquid HLP#7 globallyLists Asia; Japan not individually verified The house vault with one of the best free loss records in the pool and the worst disclosure of it: a keyless endpoint returns net PnL from inception 10 May 2023 and a PnL-inclusive APR (0.0404, about 4%, on 29 September 2026), while the 951-byte operator page uses the word 'loss' zero times.
Verifiable loss of record — 7/10Pool protection mechanism — 6/10#8 for JapandYdX MegaVault#8 globallyLists Asia; Japan not individually verified The pool's most candid loss disclosure attached to its worst exit terms: a USDC vault that market-makes 268 permissionlessly-listed dYdX markets, whose own FAQ says losses 'could outweigh returns', whose free indexer publishes only the last ~90 days (too short to contain a single loss day), and whose withdrawal slippage is documented up to '100% slippage fee and receive $0'.
Pool protection mechanism — 6/10Verifiable loss of record — 5/10#9 for JapanAster ALP#9 globallyLists Asia; Japan not individually verified The house vault that documents what you pay to the basis point and never once says what you risk: ALP holders are the market-maker counterparty for Aster's 1001x Simple Mode book, with no published NAV series, no contract address to read one from, and no page stating what happens when trader profit exceeds pool value.
