​
Overview

The Payment Manager demonstrates Lit Protocol’s payment system - a billing system for decentralised cryptographic services. Users pay for compute resources on the Lit network to access core services like:
  • Encryption/Decryption - Secure data with programmable access control
  • PKP Signing - Cryptographic keys that can sign transactions based on conditions
  • Lit Actions - Serverless functions with cryptographic capabilities
Similar to how you pay AWS for cloud computing, this\system ensures the decentralised network can sustain itself and pay node operators. You can deposit funds, request withdrawals with security delays, and manage balances for yourself or other users (enabling applications to sponsor their users’ costs for better UX).
