Microtransactions & Cashback Systems

INTMAX enables high-frequency, low-cost transactions with native privacy and scalability. This makes it ideal for use cases where traditional Ethereum transactions are economically infeasible—such as micropayments, in-app rewards, and automated cashback systems.

What You Can Build

  • Pay-per-view content
  • Streaming payments (e.g., pay-per-second)
  • In-app purchases under $0.01
  • Loyalty programs and reward points
  • Automatic cashback for users or agents
  • AI agent-based economic flows

Why INTMAX?

Traditional L1 and even most rollups struggle with microtransactions due to:

  • High fixed gas costs per transaction
  • Privacy concerns (every payment is public)
  • Centralized sequencer bottlenecks
  • Need to maintain shared state or smart contracts

INTMAX avoids these with a stateless, proof-based protocol that minimizes on-chain data (~5 bytes onchain ), while shifting computation and storage to the user level.

Architecture Overview

  1. User Deposits to the rollup with a one-time setup.
  2. Microtransactions happen off-chain via hashed commitments and private ZK proofs shared peer-to-peer.
  3. Aggregators bundle transaction roots with signatures; on-chain posting cost is amortized over thousands of transactions.
  4. Cashback or rewards can be issued off-chain or on a periodic basis using batched transactions.

No on-chain cost is incurred per individual microtransaction, enabling economic viability even at sub-cent levels.

Developer Advantages

Sample Applications

Project NameUse Case
Pay-per-Click NetworkPublishers earn a few cents per valid click
Streaming PaymentsUsers pay per second for audio/video access
Cashback WalletEarn % back on every INTMAX-based transaction
AI Agent PaymentsAgents auto-transact in small denominations

Integration Path

Use the intmax-client-sdk to:

  • Construct small-denomination transactions and batch rewards
  • Automate Merkle proof generation and propagation
  • Handle periodic cashback issuance through off-chain logic

For cashback, design your aggregator or platform to include cashback transactions in user batches or as separate off-chain incentives.

Key Takeaway

INTMAX unlocks sub-cent economic design for dApps—no longer bottlenecked by gas or privacy. If your users act frequently, pay small amounts, or earn tiny rewards, this is the infrastructure you’ve been waiting for.
