In the Rapidz app, 'Earn' feature is classified into two options, Staking Solana and Earn USDC.
Staking Solana is the process of participating in the operation of a blockchain network by locking up a specific amount of cryptocurrency to support activities such as transaction validation and network security.
In return, Rapidz Pay users will earn rewards, typically in the form of additional cryptocurrency, while contributing to the stability and efficiency of blockchain networks.
Earn USDC is a feature that allows you to earn daily interest by depositing a certain amount of USDC (on the Arbitrum network) into the Rapidz system. Rewards are calculated based on the Annual Percentage Yield (APY) and paid out on a daily basis. More USDC you hold, the more you earn!
