Katana vs Mantle

Katana is a DeFi Layer-1 chain incubated by Polygon Labs and GSR, designed to maximize on-chain liquidity and real yield. Its Vaultbridge system redeploys bridged assets like ETH and USDC into yield strategies on Ethereum, while Chain-owned Liquidity (CoL) channels 100% of sequencer fees into deep, protocol-controlled liquidity pools. Katana’s native AUSD stablecoin, backed by US Treasuries, powers lending markets and DEX liquidity with off-chain yield incentives.

Mantle is a modular Ethereum Layer‑2 that decouples execution, data availability and settlement, using Optimistic rollup proofs on Ethereum mainnet and EigenDA for cheap blob‑based data. Its BitDAO‑backed treasury subsidises sequencer fees, keeping swaps under $0.05 even during L1 congestion. The network went live in July 2023 and now hosts over 150 dApps including the Mantle DEX and Fusion perpetuals.
