MAP Protocol Token Drops 96% After Bridge Mint Exploit

MAP Protocol Token Falls 96% After Quadrillion MAPO Mint Exploit – Bridge Paused and Migration Announced

Key Takeaways

• MAP Protocol’s MAPO token dropped 96%, falling from $0.003 to $0.0001 after a quadrillion-token mint exploit.
• An attacker tricked the Butter Bridge into minting 1 quadrillion MAPO tokens, nearly 5 million times the reported 208 million supply.
• Nearly one billion tokens were dumped on Uniswap, draining about 52 ETH valued at $180,000.
• The bridge between mainnet MAPO and MAPO ERC-20 was paused, and mainnet operations were halted for migration.
• The team announced it is coordinating with external security partners and will issue a new contract address.

MAPO Price Drops to All-Time Low Following Inflationary Attack

MAP Protocol’s native token MAPO fell sharply after an exploit led to the minting of 1 quadrillion new tokens. The price declined from $0.003 to $0.0001, marking a 96% drop and setting a new all-time low according to market data referenced in the source material.

The scale of the mint was significant. The attacker generated nearly 5 million times the reported circulating supply of 208 million MAPO tokens. The newly minted tokens were transferred to a newly created externally owned account.

The sudden and extreme increase in supply triggered immediate market reaction. Within hours, the token price reflected the inflationary impact of the exploit, with trading activity accelerating as the incident became public.

Butter Bridge Exploit Originated at the Contract Layer

According to blockchain security firm Blockaid, the exploit did not stem from a compromised private wallet. Instead, it originated at the Solidity contract layer of the Butter Bridge, the cross-chain bridge built on MAP Protocol.

Blockaid reported that the attacker first submitted a legitimate oracle multisig-signed message. After that, they deployed a malicious contract to a targeted address and resent a manipulated retry message. Because the manipulated message produced the same hash structure as the legitimate one, it appeared valid to the system.

This allowed the attacker to bypass verification controls and trick the bridge into minting the massive quantity of tokens. The exploit therefore relied on the structure and validation process of cross-chain messaging within the bridge rather than on stolen credentials.

Token Dump Drains Liquidity Pools on Uniswap

After minting the tokens, the attacker used the externally owned account to offload nearly one billion MAPO tokens onto Uniswap liquidity pools. According to Blockaid, this activity drained approximately 52 ETH, valued at around $180,000.

In addition to the tokens already sold, the attacker reportedly controls close to one trillion MAPO tokens. The existence of such a large remaining balance introduces ongoing technical and operational challenges for the protocol, particularly regarding token supply integrity and market stability.

The immediate dumping activity contributed to the sharp decline in MAPO’s price and further intensified market reaction following disclosure of the exploit.

Bridge Paused and Migration to New Contract Initiated

Within an hour of the incident becoming known, MAP Protocol stated in a post on X that it was aware of the issue and coordinating with external security partners on investigation and containment.

The team paused the bridge between mainnet MAPO and MAPO ERC-20. Butter Bridge separately confirmed the pause and stated that user funds were not at risk. Pending swaps were held, according to the communication.

Due to the scale of the exploit, MAP Protocol also paused mainnet operations and began a migration process. The team indicated that a new contract address would be announced as part of the recovery plan.

The migration reflects an attempt to isolate the compromised contract environment and restore functionality under revised contract parameters.

Exploit Occurs Amid Multiple DeFi Incidents in the Same Month

The incident involving MAP Protocol occurred during a month in which at least 18 decentralized finance and blockchain protocols were reportedly compromised. These included THORChain and RetoSwap, as cited in the source material.

The MAP Protocol case specifically highlights vulnerabilities in cross-chain infrastructure. In this instance, the exploit relied on message validation logic within a bridge mechanism, rather than direct theft of private keys.

Cross-chain bridges are designed to facilitate transfers between different blockchain environments. In this case, the Butter Bridge connected mainnet MAPO and MAPO ERC-20 representations. The exploit demonstrated how weaknesses in verification processes can be leveraged to inflate supply and disrupt token economics.

Our Assessment

The MAP Protocol incident resulted in the minting of 1 quadrillion MAPO tokens and a 96% price decline. The exploit originated at the contract layer of the Butter Bridge and enabled the attacker to mint and sell a significant number of tokens, draining 52 ETH from liquidity pools.

In response, MAP Protocol paused bridge and mainnet operations and initiated a migration to a new contract address while coordinating with external security partners. The case adds to a series of protocol compromises reported in the same month and underscores operational risks associated with cross-chain bridge infrastructure based on the facts presented.
