Stader Labs (ETHx) offers multi-chain LSTs across Ethereum, Polygon, BNB, and others. ETHx uses a permissionless design with 12-ETH node minimums (vs Rocket Pool's 16 ETH). Growing but small vs tier-1 LST leaders.
Multi-chain LST reach
Stader operates LSTs on 7+ chains — MATICx (Polygon), BNBx (BNB Chain), FTMx (Fantom), plus ETHx on Ethereum. For users diversified across multiple PoS chains, Stader offers one-brand LST access.
ETHx permissionless design
ETHx requires only 12 ETH per node (vs Rocket Pool's 16 ETH), lowering the barrier for permissionless node operators. Interesting design bet on decentralization.
Verdict
Stader is the multi-chain LST specialist. Smaller than tier-1 but genuinely differentiated by chain coverage and lowest-in-class ETH node minimum.
