Description
node101 Staking is a delegation service enabling users and institutions to earn staking rewards across multiple proof-of-stake networks without operating validator infrastructure. Delegators assign tokens to node101-managed validators, which handle block production and reward distribution. The service includes restaking options through integrated protocols and whitelabel validator management for corporate clients requiring custom infrastructure.Category: Staking Service
Pulsar Chain
