MAP Protocol Token Crashes After Suspected Infinite-Mint Bridge Exploit

MAP Protocol’s MAPO token collapsed on May 20 after an early onchain alert pointed to a suspected infinite-mint exploit tied to its Butter Bridge infrastructure.

The mainnet alert said MAP Protocol’s token was exploited through an infinite mint, with mint transactions flagged on Ethereum and BNB Chain. The same alert said the exploiter had earned 52.2 ETH, worth about $110,000, at the time it was posted.

A wider incident summary placed the mint at 1,000,000,000,000,000 MAPO tokens, with the tokens reportedly routed from the zero address to wallet 0x40592025392BD7d7463711c6E82Ed34241B64279. The suspected path involved a spoofed cross-chain message through Butter Bridge V3.1’s OmniServiceProxy contract, allowing unauthorized minting on Ethereum and BNB Chain.

Live market data shows the damage clearly. MAPO traded near $0.00013 after the incident, down roughly 95% over 24 hours, with its 24-hour range stretching from about $0.003097 to $0.0001091. CoinGecko also listed the token’s market cap below $1 million after the crash, with most tracked volume concentrated on Uniswap V4 markets.

Bridge Validation Risk Hits Another Token

MAP Protocol is an omnichain infrastructure project built around BTC, stablecoin and tokenized-asset swaps. Its architecture focuses on light clients and MPC-based threshold signatures for cross-chain verification, but the suspected exploit appears to involve bridge-message validation rather than a compromise of every supported network.

That distinction is important for users. This should be treated as a Butter Bridge or token-minting incident unless MAP Protocol or a security firm confirms broader network impact. At publication, no formal MAP Protocol response outlining mitigation steps, contract pauses, token treatment or user guidance was visible in the checks reviewed for this article.

The incident lands during a tense stretch for cross-chain infrastructure. DeFi teams have been reconsidering bridge and oracle dependencies as bridge security scrutiny grows across the sector, especially where wrapped assets, token supply controls and cross-chain messages sit behind live liquidity.

For MAPO holders and liquidity providers, the immediate risk is supply integrity. Follow-up disclosures need to clarify whether the affected contracts are paused, whether exchanges or DEX front ends will restrict trading, how the fake supply will be handled, and whether any remaining attacker-held tokens can still hit liquidity pools.
