@Hyperbridge @Web3Foundation @Parity @Polkadot - please consider this proposal!
All victims are very open to new ideas and other ways and mechanisms of recovery. If Hyperbridge does not involve in the idea proposed below and Web3 Foundation is not contacting Hyperbridge to work out a realistic and valuable solution to compensate the users, hack victims will prepare a government proposal to compensate the users total losses without Hyperbridge involvement.
On April 16, 2026, Drift Protocol announced a $147.5M recovery package (Tether plus partners) for their $295M exploit. That structure is a direct example of how an ecosystem can take responsibility for endorsed infrastructure.
Proposal:
A Repayable Recovery Loan for Hyperbridge Exploit Victims & Allocation of unused vDOT from Singularity Campaign to Victims
Summary
On April 13, 2026, Hyperbridge’s Token Gateway was exploited via a forged MMR proof (missing bounds check in HandlerV1, challengePeriod set to zero). Hyperbridge has confirmed $2.5M in total realized losses across Ethereum, Arbitrum, Base, and BNB Chain. LP losses in the DeFi Singularity pools are estimated at approximately $1.5-1.8M at the time of the exploit. All affected pools were part of the DeFi Singularity campaign (Referenda #1439), a 795,000 DOT treasury-funded initiative that actively recruited external LPs.
The DeFi Singularity campaign delivered only 336,593 vDOT in incentives during the first 6 months (Polkadot DeFi Singularity Report).
The original campaign allocation was 795,000 DOT, meaning approximately 40% of the allocation (~$600-800K at current prices) remains unspent.
Since the pools these incentives were intended for are now compromised, this unused allocation is a natural candidate for redirection toward LP recovery through governance action
Hyperbridge Is Polkadot Infrastructure
While there is no blame on Polkadot or the Web3 Foundation for the underlying engineering failure at Hyperbridge, it is important to recognize that Hyperbridge is not a third-party protocol that happened to build on Polkadot. The Web3 Foundation itself documents Hyperbridge as core Polkadot infrastructure on Hyperbridge Overview - Polkadot Wiki (Copyright Web3 Foundation). The Wiki describes Hyperbridge as providing “Full Node Security in cross-chain bridges” and guaranteeing “swift, secure, and reliable execution of all cryptographic operations.” W3F led Hyperbridge’s seed round as its inaugural funding initiative. W3F’s CEO publicly stated Hyperbridge “embodies the highest standards of security.” The DAO designated it as the native bridge and allocated 795,000 DOT to recruit LPs into its pools.
Why the Ecosystem Should Act
LPs responded to an official Polkadot DAO campaign. The ecosystem endorsed, funded, promoted, and documented this protocol. Not acting sets the precedent that “the ecosystem will spend Treasury funds to recruit your capital, endorse the product, document it as official infrastructure, and call it the highest standards of security, but if it fails you are on your own.” That precedent suppresses future DeFi participation for years.
Acting here is NOT a blanket bailout. It is specific to DAO-endorsed, treasury-funded campaigns where the ecosystem actively recruited the users who were harmed. That boundary is explicit.
The Proposal
Many affected LPs are also DOT holders who care deeply about the long-term health of the ecosystem. To be clear: this is not a failure of Polkadot. But ignoring Polkadot’s and Web3 Foundation’s involvement in Hyperbridge and its campaigns, along with the endorsements and promotion mentioned above, is not the right path forward either.
The proposal is not a request for a simple bailout. It is a structured risk management response that protects the ecosystem’s reputation, avoids direct sell pressure on DOT, and keeps liquidity aligned within Polkadot. We propose a recovery loan from the Polkadot Treasury (or Web3 Foundation) to the affected LPs, with LPs pledging their recovery claim to the Polkadot Treasury (or Web3 Foundation) and Hyperbridge/Polytope Labs assuming repayment obligation for the residual. All APY incentives received by LPs will be deducted from the Polkadot recovery loan amount.
Victims receive their recovery loan through linear 12 month vesting to avoid market impact, while the Treasury is fully protected through any recovered amount (eg locked on Binance) and Hyperbridge’s repayment commitment from multiple independent streams including unused vDOT from the Singularity campaign or other incentives.
How It Works (5 Steps)
- a. The Polkadot Treasury (or Web3 Foundation) provides a recovery loan in DOT directly to victims.
- b. The loan is paid directly to verified affected LPs, NOT to Hyperbridge. Distribution is linear over 12 months (1/12 monthly) to eliminate sell pressure.
- c. Claims are calculated as net loss only: capital deposited MINUS all earned vDOT rewards. Victims forfeit rewards against the recovery amount.
- d. Hyperbridge/Polytope Labs assumes repayment obligation to the Treasury through multiple independent streams: bridge fees from Intent Gateway (operational) and Token Gateway (post-relaunch), BRIDGE token treasury distributions (35% of total supply, already committed as residual backstop), outstanding vDOT rewards from the DeFi Singularity campaign, unspent Singularity allocation, Binance recovery proceeds.
- e. The Treasury gets its DOT back over time
Claim Calculation and Estimated Amount
- Net loss only: documented capital deposited minus all vDOT rewards earned during the campaign. Exact amount determined on the basis of a verified pre-exploit snapshot across all four affected chains.
- Preliminary estimate: $1.5-1.8M total LP losses before reward deduction. Actual Treasury loan may be significantly lower after final accounting. Exact figures specified before any formal referendum.
- Distribution to Victims: 12-Month Linear Vesting, 1/12 released monthly
- No sell pressure: At the upper estimate of $1.8M before deductions, maximum monthly distribution is only approximately $150K. DOT’s daily trading volume exceeds Millions across exchanges. DOT circulating supply is 2.2 billion. Zero systemic risk or sell pressure.
Repayment to Treasury
Repayment runs separately from victim distribution. Hyperbridge/Polytope Labs assumes the full repayment obligation from:
- a. Bridge fees from Intent Gateway (operational) and Token Gateway (post-audit relaunch)
- b. BRIDGE token treasury distributions (35% of total supply)
- c. Binance recovery proceeds (“a significant amount” as stated by Hyperbridge)
- d. Outstanding vDOT rewards from the DeFi Singularity campaign and other unspent DeFi Singularity campaign allocation to Hyperbridge and BiFrost
- On-chain repayment tracking. If recovery resolves quickly, repayment completes in months. If slower, bridge fee revenue and BRIDGE treasury distributions continue until fully repaid.
Hyperbridge in Numbers
- Over $400M cumulative processed volume (February 2026)
- 14 connected networks (Ethereum, Arbitrum, Base, BNB, Optimism, Polygon, others)
- Ranked 5th most active bridge by daily addresses on Token Terminal (November 2025)
- 59,000+ cross-chain messages processed
- Intent Gateway launched September 2025, continues operating normally
Preempting Common Objections
-
“LPs accepted the risk when they participated.” LPs accepted market risks: impermanent loss, altcoin volatility, price depreciation. What they did not accept is engineering negligence in infrastructure W3F itself endorses and documents as core Polkadot infrastructure. A missing bounds check plus challengePeriod hardcoded to zero is not novel cryptographic failure. It is a basic implementation error any standard audit cycle should have caught.
-
“The yields were high, no compensation warranted.” DeFi Singularity pools offered no more than 10-15% APR at the end, even before accounting for impermanent loss and altcoin price depreciation. After those factors, effective returns were significantly lower. The S&P 500 delivers 8-10% per year with zero effort, no IL, no smart contract exposure. Higher DeFi APR exists to compensate for Impermanent Loss and volatility, not for implementation failures in endorsed infrastructure. And in any case: All earned vDOT rewards are deducted from claims. Net loss only.
-
“This sets a dangerous precedent for bailing out every hack.” The precedent is specific and narrow: when the DAO actively funds a campaign that recruits external users into endorsed infrastructure, and that infrastructure fails due to implementation negligence, the ecosystem responds. Unendorsed third-party exploits would not qualify. The opposite precedent, not acting, is worse: it tells future users they are on their own even after responding to DAO recruitment and infrastructure promotion and endorsement by Polkadot, Web 3 Foundation and its top level management and founders.
-
“The Treasury should not cover application-layer losses.” Hyperbridge is not application-layer. It is documented as Polkadot infrastructure by W3F on its own Wiki, DAO-designated as native bridge, W3F inaugural funding initiative, and promoted with 795,000 DOT. Treating it as a random third-party app contradicts the ecosystem’s own documentation.
-
The connection here is strong: Hyperbridge exists because of W3F seed funding, was DAO-designated as native bridge, and was promoted with a direct treasury allocation that recruited the harmed users.
-
“Privatising the upside, socialising the downside.” Neither applies. Upside is not privatised: all earned vDOT rewards get deducted from recovery. Downside is not socialised: this is a repayable loan, not a grant. Temporary Treasury risk for reasons mentioned above, not permanent loss.
-
“Trust issue with Hyperbridge, why give them more?” The loan goes directly to victims, not to Hyperbridge.
What This Does NOT Ask For
- No new DOT emission (compliant with March 2026 supply cap)
- No grant (repayable loan with on-chain tracking)
- No windfall (reward forfeiture, net loss only)
- No precedent for bailing out every hack
- No sell pressure (12-month linear vesting, ~$150K/month max vs Millions of daily DOT trading volume)
Next Steps
- a. Community discussion on this framework
- b. Await Hyperbridge post-mortem with final on-chain accounting
- c. Hyperbridge/Polytope Labs to formally accept repayment by using above mentioned income streams (we have asked the team to take ownership of this proposal; if they do not engage, the affected LP community will bring it forward)
- d. Web3 Foundation / Polkadot Treasury engagement as lead investor
- e. Bifrost engagement on outstanding vDOT distribution
- f. Formal OpenGov referendum once terms are agreed and figures confirmed
Closing
Technology without users is dead. Polkadot has world-class engineering, world-class validators, world-class consensus. What it needs now is users who trust that when they respond to an ecosystem-funded, ecosystem-endorsed campaign, the ecosystem stands with them when something fails. This proposal is cost-neutral if repayment works. It is a direct precedent for how a mature ecosystem handles crises. It is the response that protects Polkadot’s credibility for years to come.
This is a pre-proposal for discussion. We welcome feedback from anyone with OpenGov experience, from Polytope Labs and W3F directly, and from other affected LPs.
