MANTRA has released a complete review of the August 20 security incident. The incident stemmed from an unsigned integer underflow vulnerability in the balance accounting layer of the upstream dependency, cosmos/evm. Without requiring privileged access, the attacker transferred a combined total of 720,923,967.99 MANTRA tokens from a burn address and a legacy genesis multisig address, amounting to approximately $3.6 million at pre-incident prices.
RWA Layer 1 blockchain MANTRA Chain announced that the vulnerability in the Cosmos-EVM module has been patched, the network has resumed operations and block production, and the incident did not affect user funds. The team will release a complete post-incident analysis report in the coming days.
