What happened to the Map Protocol MAPO token?

MAPO crashed about 96% after an attacker exploited the Butter Network cross-chain bridge and minted a quadrillion fake tokens. The exploit massively inflated supply and triggered heavy selling into liquidity pools. MAPO fell from roughly $0.003 to around $0.0001 within hours.

How did the Butter Network exploit work?

The attacker reportedly manipulated a Solidity smart contract vulnerability in the Butter Network bridge. According to security firm Blockaid, the attacker resent a modified “retry” message that looked legitimate to the bridge verification system. That allowed the protocol to approve an enormous unauthorised token mint.

How much money did the MAPO attacker steal?

The attacker drained around 52 ETH, worth roughly $180,000, from Uniswap liquidity pools after dumping around a billion fake MAPO tokens. However, the bigger concern is that the attacker still controls nearly a trillion remaining tokens. Those holdings could threaten other liquidity pools and exchange markets if sold.

Was Map Protocol hacked through stolen private keys?

No, the exploit did not involve stolen private keys or compromised validators. Blockaid said the issue was a classic Solidity vulnerability involving multiple dynamic fields in the smart contract logic. That means the exploit came from flawed contract validation rather than direct wallet compromise.

What is Map Protocol and what does MAPO do?

Map Protocol is an omnichain network designed to move Bitcoin, stablecoins and tokenised assets across multiple blockchains. It connects networks including Ethereum, BNB Chain, Tron, Solana and Bitcoin. MAPO is the ecosystem’s native token used for network activity and protocol functions.

What is Map Protocol doing after the exploit?

Map Protocol said it paused its mainnet and started a migration process while investigations continue. The project plans to launch a new contract address and conduct an asset snapshot. Tokens held by attacker-controlled wallets are expected to be invalidated in the migration.

Are user funds on Butter Network safe after the exploit?

Butter Network said user funds were not directly at risk and that ButterSwap has been paused as a precaution. However, liquidity providers and token holders were still heavily impacted by the collapse in MAPO’s price. Traders should still monitor whether additional vulnerabilities are discovered.

Why are cross-chain bridges getting hacked so often?

Cross-chain bridges are frequent attack targets because they manage large pools of assets while relying on complex smart contract logic. Even small validation bugs can let attackers mint fake tokens or drain funds. Bridge exploits remain one of the highest-risk areas in DeFi because they connect multiple blockchains and trust systems.

Map Protocol token sinks after bridge exploit

Written by Isaac FrancisPublished May 21, 2026, 5:27 AM

MAPO crashed 96% on Wednesday after an exploit targeting the Butter Network allowed an attacker to mint a quadrillion fake tokens and flood the market.

The exploit inflated the token supply tens of thousands of times beyond the legitimate circulating amount, sending MAPO from about $0.003 to nearly $0.0001 within hours, according to CoinGecko data.

The attacker used a newly created externally owned account to dump around one billion MAPO tokens and drain about 52 ETH worth roughly $180,000 from Uniswap liquidity pools while still holding nearly a trillion tokens that may threaten additional pools and exchange listings.

Blockaid said the exploit relied on a Solidity contract vulnerability in which the attacker resent a modified retry message that appeared legitimate to the bridge validator and triggered the unauthorised mint without compromising private keys or light clients.

Map Protocol said it paused the mainnet and started a migration process while the investigation continues, adding that:

“Any remaining tokens held by attacker-controlled addresses will be fully invalidated and will not be included in any future snapshot or conversion process.”

Following the announcement the MAPO token price was down at around $0.0001.

The incident adds to a growing wave of cross-chain bridge exploits affecting decentralised finance projects this month, including attacks linked to THORChain, Transit Finance and the TON-TAC bridge, which separately disclosed a $2.68 million exploit tied to missing validation checks in sequencer software.

At the time of reporting, MAP Protocol price was $0.001973.
