Mantle Network Snapshot
Ethereum L2 that grew out of BitDAO, governed by MNT holders with one of crypto's largest treasuries. Mantle was the first OP Stack chain to convert to a ZK validity rollup via OP Succinct — cutting finality from days to about an hour — and positions itself as an onchain banking and RWA hub anchored by the mETH liquid-staking ecosystem.
