Polkadot-linked Hyperbridge exploit losses hit $2.5M

TLDR

  • Hyperbridge increased its April 13 exploit loss estimate to about $2.5 million after a broader review across four chains.
  • The attacker extracted around 245 ETH and then minted about 1 billion fake bridged DOT tokens.
  • Polkadot confirmed that only DOT bridged through Hyperbridge was affected, while native DOT remained secure.
  • The exploit targeted a flaw in the Merkle Mountain Range proof verification logic in HandlerV1.
  • Hyperbridge paused Token Gateway operations and is working with Binance and law enforcement on fund recovery.

Hyperbridge has raised its loss estimate from the April 13 Token Gateway exploit to about $2.5 million. The project had earlier reported losses of nearly $237,000 based on early on-chain activity. However, a broader review across four chains revealed deeper damage and a two-phase attack.

Polkadot Confirms Bridged DOT Exposure

Hyperbridge said it revised the figure after reconciling transactions across Ethereum, Base, BNB Chain, and Arbitrum. The team explained that it reviewed attacker activity in two phases and included losses from incentive pools. As a result, it increased the total realized losses to roughly $2.5 million.

Polkadot stated that the incident affected only DOT bridged through Hyperbridge to Ethereum. The network confirmed that native DOT on Polkadot remained unaffected. It also clarified that the broader Polkadot ecosystem did not face a direct impact.

Hyperbridge initially focused on the visible sell-off of bridged DOT on Ethereum. However, further investigation showed that the attacker first extracted about 245 ETH from Token Gateway. The attacker then moved into a second phase that involved minting about 1 billion bridged DOT tokens.

The attacker minted the tokens without authorization and sold them into available decentralized exchange liquidity. Consequently, the sales pressure deepened losses across supported chains. Hyperbridge confirmed that the exploit centered on its Token Gateway component.

Ethereum, Base, BNB Chain, and Arbitrum Impacted

Security researchers traced the flaw to the Merkle Mountain Range proof verification logic. The vulnerability affected Hyperbridge’s HandlerV1 path and enabled forged cross-chain messages. As a result, the attacker gained control over admin functions tied to the bridged DOT contract.

The attacker used that access to mint fake bridged DOT tokens on Ethereum. The attacker then dumped those tokens into limited liquidity pools. This sequence expanded losses beyond the initial ETH extraction.

Hyperbridge stated that the damage remained isolated to Token Gateway. It confirmed that bridged token contracts on Ethereum, Base, BNB Chain, and Arbitrum were affected. However, it said that Intent Gateway and related products were not impacted.

The team said it traced a large portion of exploited funds to Binance. It added that it works with Binance’s compliance team and law enforcement to freeze and recover assets. Hyperbridge said it plans to allocate BRIDGE tokens if recovery efforts fail.

All Token Gateway bridging remains paused while the team finalizes a patch. Hyperbridge said it will complete an independent audit and add safeguards before resuming operations. It confirmed that it will publish the audit report before restoring full functionality.

PI steadies at $0.1770 amid core team’s mainnet upgrade plans

Key takeaways 

  • Pi Network’s PI token holds steady at $0.1730, up 4.5% from the previous day. 
  • The Pi Core Team’s upgrade to enable smart contracts, with a deadline set for April 27, is a potential catalyst. 

Pi Network’s PI token has managed to hold steady around $0.1770 as of Friday, adding a 4.5% gain from the previous day. 

The Pi Core Team (PCT) is driving momentum with the impending upgrade to the mainnet, which will enable smart contract functionality—expected to be a key catalyst for price movement.

PI rallies ahead of the Protocol 22 upgrade

PI is up 4.5% in the last 24 hours, outperforming the broader cryptocurrency market. The rally comes after the Pi Core Team announced that April 27 is the final deadline for all mainnet nodes to complete necessary steps for remaining connected to the network, as part of the Stellar Protocol version 22 upgrade. 

While this upgrade will cause a brief 15-minute downtime during internal data transfer, it lays the groundwork for future improvements. Additionally, the full upgrade to version 26 is slated for June 22, ahead of Pi2Day on June 28.

Will PI rally higher in the near term?

The PI/USD 4-hour chart is bearish and efficient, trading above the $0.1770 level. However, Pi Network remains in a bearish posture, with the token still trading below the 50-, 100-, and 200-day Exponential Moving Averages (EMAs). 

The immediate resistance level is marked at $0.1785, corresponding to the 50-day EMA, followed by stronger resistance at $0.1865 (100-day EMA) and $0.2334 (200-day EMA).

However, momentum indicators present mixed signals. The Relative Strength Index (RSI) at 71 is above the neutral 50 line, and is heading into the overbought region.

The Moving Average Convergence Divergence (MACD) crossing above its signal line indicates growing bullish momentum.

On the downside, key support is found at $0.1556, near the February 23 low, with further weakness potentially exposing $0.1310 if the market slips below this level.

Crypto in Sustained Winter as Q1 CEX Volumes Drop

Crypto in Sustained Winter as Q1 CEX Volumes Drop

The cryptocurrency market has entered a “sustained crypto winter,” according to CoinGecko, as spot trading volumes on centralized crypto exchanges rapidly fell over the first quarter of 2026.

Crypto market capitalization fell by more than 20% during the first quarter as “bearish momentum from late 2025 collided with global geopolitical instability,” CoinGecko said in a report on Thursday.

That caused the top 10 centralized exchanges by spot volume to record a 39% decrease in trading volume over the quarter ended in March, dropping to $2.7 trillion from $4.5 trillion in the fourth quarter of 2025.

The drop comes as the crypto market has struggled to maintain positive momentum after Bitcoin (BTC) hit a record high of more than $126,000 six months ago, as the wider market reacted to fears of an economic slowdown and uncertainty over the fallout from US-Israeli strikes on Iran in February.

March was the “weakest month,” according to CoinGecko, with $800 billion in trading volume, the lowest since November 2023.

CoinGecko said that the contraction in crypto markets was worsened by Kevin Warsh’s nomination as US Federal Reserve chair, which signaled “a potential hawkish shift in US monetary policy.”

It added that daily trading activity across the crypto market saw “a significant decline” over the first quarter, with average daily trading volumes at $117.8 billion, a drop of 27% compared to the fourth quarter of 2025.

All of the top 10 spot centralized exchanges recorded declining volumes in the first quarter, CoinGecko said, with HTX, formerly Huobi, seeing “the biggest slump” quarter-on-quarter as volumes dipped 55% to $133.6 billion.

It said that Bitcoin fell 22% over the first quarter, “continuing to underperform all assets, despite US equity indexes such as NASDAQ and S&P 500 falling -7.1% and -4.8% respectively, their worst quarterly returns since 2022.”
