🔷 What Is Arbitrum for Payments?
Arbitrum is a leading Layer 2 scaling solution for Ethereum, built using Optimistic Rollup technology. It processes transactions off-chain and settles them to Ethereum mainnet in batches, enabling fast, low-cost payments while inheriting Ethereum's security.
Arbitrum is fully EVM-compatible, meaning developers can deploy existing Ethereum smart contracts with minimal changes, and users can use the same wallets (MetaMask, etc.) they already know. With over $15 billion in total value locked (TVL) and a thriving ecosystem, Arbitrum is one of the most popular networks for DeFi and payments.
Arbitrum combines Ethereum's security with low fees and fast finality. It's the go-to choice for users who want to stay within the Ethereum ecosystem but can't justify paying $5–$50 per transaction on mainnet. With fees under $0.05, Arbitrum makes everyday payments and micro-transactions economically viable.
📋 Arbitrum Solutions for Payments
Arbitrum offers multiple solutions, each optimized for different payment use cases:
The flagship Arbitrum chain. A full-featured Optimistic Rollup with deep DeFi liquidity, thousands of dApps, and fees of $0.01–$0.05. Best for general payments, DeFi, and enterprise use.
A specialized rollup for gaming and social applications. Uses a Data Availability Committee (DAC) for ultra-low fees ($0.001–$0.01). Best for high-frequency, low-value payments like in-game micro-transactions.
A framework for launching custom, permissionless L2/L3 chains that settle to Arbitrum. Ideal for enterprises building dedicated payment networks with specific requirements.
The official bridge for moving ETH and ERC-20 tokens between Ethereum mainnet and Arbitrum. Fast, secure, and widely trusted by the ecosystem.

| Base Chain | Ethereum (L2 Rollup) | TRON (own L1) |
| Speed | 1–3 seconds | ~1–3 seconds |
