MAPO Crashes After Massive Cross-Chain Bridge Exploit

The attacker dumped around one billion MAPO tokens into Uniswap liquidity pools, draining roughly 52 ETH, and still reportedly controls close to a trillion tokens. After the incident, Map Protocol paused its mainnet and began a migration process, while Butter Network paused ButterSwap as investigations into the exploit continue. MAPO Exploit Wipes Out Token Value The crypto sector faced yet another security incident this week after MAPO, the native token of the Map Protocol ecosystem, crashed due to an exploit involving the Butter Network cross-chain bridge. The attack allowed a malicious actor to mint an enormous quantity of MAPO tokens, far exceeding the project’s legitimate circulating supply. MAP Protocol’s price action over the past 24 hours (Source: CoinCodex) According to reports, the attacker managed to mint approximately one quadrillion MAPO tokens through a vulnerability tied to the bridge’s Solidity smart contract layer. The exploit immediately destabilized the token’s value, which sent the price crashing from around $0.003 to almost $0.0001 in only a few hours. Blockchain security firm Blockaid stated that the attacker used a newly created externally-owned account to dump around one billion MAPO tokens into Uniswap liquidity pools, draining approximately 52 ETH, valued at roughly $180,000 at the time. Despite already extracting a lot of liquidity, the attacker reportedly still controls close to a trillion MAPO tokens. This raised concerns that even more decentralized exchanges, liquidity pools, and potentially even centralized exchange listings could be vulnerable if the remaining tokens are moved or sold. The exploit occurred during a particularly difficult month for the DeFi industry. At least 18 protocols reportedly suffered breaches or exploits. Recent victims included THORChain, Transit Finance, Echo Protocol, TrustedVolumes, Verus Protocol’s Ethereum bridge, Ekubo, and RetoSwap. Map Protocol later confirmed that the vulnerability originated from the Solidity contract layer rather than compromised private keys or broken light clients. According to Blockaid’s analysis, the attacker initially submitted a legitimate oracle multisig-signed message before deploying a malicious contract to a targeted address. The attacker then resent a manipulated retry message that appeared valid because it produced an identical hash structure. This ultimately tricked the bridge into authorizing the massive token mint. In response, Map Protocol paused its mainnet operations and announced that it started a migration process while the investigation continues. Butter Network also paused ButterSwap but said that user funds were not directly at risk. The project also stated that a new contract address would soon be announced, alongside a future asset snapshot to support token migration efforts. Any tokens linked to attacker-controlled wallets will reportedly be invalidated and excluded from future conversions.

Dogecoin (DOGE) Faces Fresh Downside Risk, Sellers Stay Aggressive

Dogecoin started a recovery wave above the $0.1040 zone against the US Dollar. DOGE is now facing hurdles near $0.1075 and might struggle to continue higher. DOGE price started a recovery wave from $0.1020 and climbed above $0.1040. The price is trading below the $0.1075 level and the 100-hourly simple moving average. There was a break above a bearish trend line with resistance at $0.1040 on the hourly chart of the DOGE/USD pair (data source from Kraken). The price could continue to move up if it stays above $0.1020. Dogecoin Price Hits Resistance Dogecoin price started a recovery wave from the $0.1020 zone, like Bitcoin and Ethereum . DOGE climbed above the $0.1035 and $0.1040 resistance levels. There was a decent upward move above the 23.6% Fib retracement level of the downward move from the $0.1127 swing high to the $0.1021 low. Besides, there was a break above a bearish trend line with resistance at $0.1040 on the hourly chart of the DOGE/USD pair. Dogecoin price is now trading below the $0.1075 level and the 100-hourly simple moving average. If there is another recovery wave, immediate resistance on the upside is near the $0.1062 level. The first major resistance for the bulls could be near the $0.1075 level or the 50% Fib retracement level of the downward move from the $0.1127 swing high to the $0.1021 low. The next major resistance is near the $0.1088 level. A close above the $0.1088 resistance might send the price toward the $0.1120 resistance. Any more gains might send the price toward the $0.1150 level. The next major stop for the bulls might be $0.1165. Another Decline In DOGE? If DOGE’s price fails to climb above the $0.1075 level, it could continue to move down. Initial support on the downside is near the $0.1040 level. The next major support is near the $0.1020 level. The main support sits at $0.10. If there is a downside break below the $0.10 support, the price could decline further.

Bitcoin’s Quantum Vulnerability: Poor Wallet Habits Expose 4.12 Million BTC

BitcoinWorld Bitcoin’s Quantum Vulnerability: Poor Wallet Habits Expose 4.12 Million BTC New on-chain data from Glassnode reveals that approximately 20% of Bitcoin’s total supply—amounting to 4.12 million BTC—is vulnerable to potential future quantum computing attacks. The risk, however, stems not from a flaw in Bitcoin’s core protocol but from widespread user behavior and poor wallet management practices. User Habits, Not Protocol Flaws, Drive the Risk According to Glassnode’s analysis, the primary vulnerability arises from practices like address reuse and partial spending. When users reuse addresses or create transactions that expose public keys on-chain, they remove the cryptographic shield that normally keeps these keys hidden behind a hash. In a future scenario where high-performance quantum computers become operational, these exposed public keys could theoretically be reverse-engineered to derive private keys. This operational exposure affects 4.12 million BTC, a figure more than double the 1.92 million BTC that is structurally exposed due to older transaction scripts like Pay-to-Public-Key (P2PK). The structural exposure is a known legacy issue, but the operational risk, driven by user behavior, is significantly larger and growing. Exchange Holdings Under Scrutiny Glassnode specifically highlighted that 1.66 million BTC held by cryptocurrency exchanges are exposed to this operational risk. This is because exchange wallets often use address reuse patterns for efficiency, inadvertently increasing the attack surface. For individual holders, the advice remains clear: use fresh addresses for each transaction and avoid practices that reveal public keys unnecessarily. What This Means for Bitcoin’s Long-Term Security The data underscores a critical distinction: Bitcoin’s protocol is not inherently broken. The cryptographic foundations, including SHA-256 and the elliptic curve digital signature algorithm (ECDSA), remain robust against current classical computing threats. The risk is forward-looking and contingent on the development of sufficiently powerful quantum computers, which experts estimate could be a decade or more away. Nevertheless, the sheer volume of exposed coins—representing a significant portion of the circulating supply—raises questions about the long-term security posture of the network. It also highlights the importance of user education and the adoption of best practices, such as using SegWit or Taproot addresses, which offer improved privacy and security features. Conclusion Glassnode’s findings serve as a sobering reminder that in cryptocurrency, human behavior often represents the weakest link in the security chain. While Bitcoin’s code remains secure, the habits of its users are creating a substantial future liability. For the industry, this is a call to action: improve wallet design, educate users, and begin planning for a post-quantum cryptographic future. FAQs Q1: Is Bitcoin currently at risk from quantum computers? No. Current quantum computers are not powerful enough to break Bitcoin’s cryptographic keys. The risk is a future projection based on the potential development of fault-tolerant quantum computers, which experts estimate is at least 10-15 years away. Q2: How can I protect my Bitcoin from quantum threats? Use best practices: never reuse addresses, use a new address for each transaction, and consider using wallets that support SegWit or Taproot. Avoid partial spending from addresses that have previously been used. Q3: Does this mean Bitcoin is broken? No. The vulnerability is not in Bitcoin’s protocol design but in user behavior. The protocol itself is sound, and the community is already researching post-quantum cryptographic upgrades for the future.

India Gold Price Today: Gold Steadies, Bitcoin World Data Shows

BitcoinWorld India Gold Price Today: Gold Steadies, Bitcoin World Data Shows Gold prices in India held steady on today’s trading session, according to data tracked by Bitcoin World. The precious metal showed little movement as market participants weighed global economic signals and domestic demand trends. Gold Price Holds Steady Amid Mixed Signals Data from Bitcoin World indicates that gold prices in India remained largely unchanged during the latest trading window. This stability comes after a period of moderate volatility driven by international market cues and currency fluctuations. The Indian gold market, one of the largest globally, often reflects a combination of global spot prices, local import duties, and seasonal demand patterns. Market Context and Influencing Factors The steady price action follows recent commentary from major central banks and evolving expectations around interest rate policies. Gold, as a non-yielding asset, is particularly sensitive to real interest rates and the opportunity cost of holding it compared to yield-bearing instruments. In India, the price is also influenced by the rupee’s exchange rate against the US dollar, as gold is globally priced in dollars. Implications for Indian Investors and Consumers For Indian buyers, a steady gold price can signal a period of relative calm, though it does not eliminate the long-term considerations of holding the metal as a hedge against inflation or currency depreciation. Jewelers and retail investors often watch for price dips to make purchases, especially ahead of the wedding season and major festivals like Diwali and Akshaya Tritiya, when gold buying is considered auspicious. Conclusion Today’s data from Bitcoin World shows gold prices in India holding steady, reflecting a broader market pause. While short-term price action remains subdued, the underlying factors of global monetary policy and domestic demand continue to shape the outlook. Investors and consumers should monitor these developments for potential shifts in the coming sessions. FAQs Q1: What is the current gold price in India according to Bitcoin World data? As of the latest update, gold prices in India are steady, with no significant change reported in today’s session. For the exact real-time price, please refer to the Bitcoin World gold price page. Q2: Why do gold prices remain stable some days? Gold prices can remain stable when market participants are waiting for clearer signals from economic data, central bank announcements, or geopolitical developments. Low trading volumes or a balance between buying and selling pressure can also lead to price steadiness. Q3: How does the Indian rupee affect gold prices in India? Since international gold is priced in US dollars, any change in the rupee-dollar exchange rate directly impacts the domestic price of gold. A weaker rupee makes gold more expensive in India, while a stronger rupee can lower prices. This post India Gold Price Today: Gold Steadies, Bitcoin World Data Shows first appeared on BitcoinWorld .

Circle’s Next Step: Hyperliquid (HYPE) Integration As The Catalyst For Real Supply-Share Gain

Bankless has been looking past the usual “partnership announcement” narrative and instead focused on what the new Hyperliquid (HYPE), Coinbase (COIN), and Circle (CRCL) deal could realistically change for USDC. In its latest write-up, the outlet argues the collaboration is more than public relations, especially at a time when stablecoin momentum has started to pick up but the deeper numbers have not shifted as quickly as some investors might expect. Bankless frames USDC’s moment as meaningful, but also incomplete—while positioning Hyperliquid as the missing platform that could help Circle’s stablecoin translate momentum into real market share. The USDC Deal As reported by Bitcoinist last week, Coinbase said it is expanding its role by becoming the official treasury deployer of USDC on Hyperliquid. In the plan, Coinbase treats USDC as an Aligned Quote Asset (AQA), while Hyperliquid’s USDH token is expected to be phased out gradually. Related Reading: Hyperliquid ETFs Send HYPE Closer To All-Time Highs—Here’s What The Data Shows Bankless says that with this latest move, improvements are concrete: a significantly better revenue split—roughly double what Hyperliquid was earning with USDH—plus additional regulatory and institutional “firepower” that comes from aligning with what it describes as crypto’s largest voice in Washington, D.C. The report also emphasizes user experience benefits, especially because USDC is a trusted stablecoin already built into the exchange experience for many traders. Bankless adds that USDC is predominantly used in Hyperliquid’s HIP-3 markets, the segment that has driven much of Hyperliquid’s visibility over roughly the past six months. From there, the argument becomes more strategic. Bankless contends that the Coinbase and Circle deal is more than “PR” because USDC already has momentum following the GENIUS Act approval, but its supply share has not meaningfully changed. It presents Hyperliquid as the fix for that mismatch—an added distribution channel that could allow stablecoin growth to compound rather than merely coexist with the existing dominant currency dynamic. Binance Reinforces USDT Dominance To support the “supply share isn’t moving” claim, Bankless points to stablecoin market composition. In April 2025, it says Tether’s USDT stablecoin held 67% of stablecoin supply while USDC held 27.6%. A year later, USDT sits at 67.3% and USDC at 28.1%. It notes that USDC transaction volume is accelerating, but the structural picture remains basically unchanged, which it describes as the central problem. The report argues that this is happening for a reason. USDC is strongest in the United States, but competition is concentrating precisely there. Outside the US, the report says, USDT still functions as the default dollar for saving, investing, and trading—meaning USDC faces a tougher environment when it comes to establishing base currency status across global trading venues. That is why distribution is presented as the priority, and perpetuals are framed as the natural battleground. Stablecoins are the quote asset that perpetuals are built around, and the ecosystem that dominates the largest exchange tends to reinforce itself. On Binance, Bankless notes, USDT is the standard against which many of the biggest markets trade. In practice, that means traders are frequently transacting against USDT, which strengthens USDT’s supply, liquidity, deposits, withdrawals, and on-chain activity. Hyperliquid May Fix That Hyperliquid, in Bankless’s telling, offers USDC a way to fight that cycle. The report includes a set of market indicators meant to show that Hyperliquid’s share in the perp ecosystem isn’t theoretical. It claims Hyperliquid holds 30% of onchain perp market share, commands 46% of onchain open interest, and operates at about 50% of Bybit’s volume, around 30% of OKX’s volume, roughly 79% of Coinbase International’s, and about 13% of Binance. Related Reading: Solana ETF Falls Behind As XRP Collects More Cash—Here’s The Catalyst Driving The Split While Hyperliquid is still smaller than Binance overall, Bankless suggests the direction is clear—toward perpetuals becoming an environment where USDC can gain more consistent exposure. The conclusion is that Coinbase and Circle can let Hyperliquid carry the reach while USDC benefits from being the stablecoin underneath the trading activity.
