Mantle
An Ethereum L2 originally built on the OP Stack with EigenDA for data availability, transitioning to a fully ZK-secured stack under BitDAO governance.
Mantle is an Ethereum Layer-2 backed by BitDAO's (now Mantle DAO's) substantial treasury. It launched as an OP Stack rollup with a modular twist: data availability is delegated to EigenDA rather than to Ethereum calldata, which lowers costs further.
Mantle has announced a longer-term migration to a ZK-secured stack and to enshrined restaking primitives. The protocol also operates mETH, one of the larger liquid staking tokens by TVL.
