MAP Protocol
Omnichain interoperability protocol with Bitcoin focus. Provides cross-chain messaging + bridges including Bitcoin.
Status (September 2026)
Butter Bridge V3.1 exploit, 20 May 2026. MAP Protocol shut down the bridge connecting MAPO ERC-20 on Ethereum to the MAPO mainnet after a reported exploit of Butter Bridge V3.1, paused mainnet operations, and began a migration to new token contracts. As of 15 September 2026 no post-mortem appears on mapprotocol.io or docs.mapprotocol.io - neither carries any notice of the incident - and MAP's Medium account has published nothing since April 2022. Press reporting on 20 May 2026 said the exploit mechanism and the extent of losses had not been disclosed.
Press reporting (20-21 May 2026, not confirmed by MAP) describes an
attacker deploying a contract that manipulated an oracle
multisig-signed message to mint roughly a quadrillion MAPO, then
dumping ~1B of them on Uniswap for 52 ETH ($180k). Treat those
figures as press-reported, not disclosed. Independent corroboration
of the date does exist: CoinGecko records MAPO's all-time low of
$0.00034224 on 20 May 2026.
The 1:1 swap to new Ethereum and BNB Chain token contracts has since
completed; CoinGecko lists both at
0x7046933234A82AF77F14625e8d0fA9Bcc5044a7E as of 15 September 2026,
and mapprotocol.io again advertises live cross-chain traffic. Whether
the Ethereum <-> mainnet bridge itself reopened could not be
independently confirmed.
Practical stance: treat MAP primarily as a case study in light-client/mint-authority bridge design. Do not route value through it without your own audit of the current MOS/Butter contracts.
Architecture
- Light-client based bridges between MAP-compatible chains.
- Bitcoin integration: SPV-style verification for cross-chain Bitcoin transactions.
- Native token: MAPO.
Use cases
- Cross-chain swaps Bitcoin ↔ EVM chains.
- Multi-chain dApps.
- Asset bridges.
Position
Niche player; smaller TVL than dominant L2s. Focus on
interoperability rather than smart-contract execution. As of
15 September 2026 MAPO's market cap is roughly $8M (CoinGecko rank
#1346) and the price is still well below its pre-exploit level
($0.003 reported on 20 May 2026), so the economic security backing
maintainer bonds is correspondingly thin.
