# What Is Ethereum?

Ethereum is the base settlement layer for most of modern DeFi, including the ecosystem where Infinite Trading products operate.

## Why Ethereum still matters for ITP users

* It is the trust layer behind smart contracts and asset custody.
* It enables transparent, non-custodial vault interactions.
* It powers the L2 ecosystems (Base, Optimism, Polygon) used for lower-cost execution.

## How this connects to Infinite Trading

Infinite Trading is built on Ethereum-compatible networks so users can:

* keep custody in their own wallets
* verify transactions and vault behavior onchain
* access automated strategies without centralized account risk

## Ethereum + Layer 2 in practice

Most users interact on L2s rather than Ethereum mainnet for day-to-day product usage:

* **Base** for fast and cost-efficient product flows
* **Optimism** for deep DeFi liquidity and automation routes
* **Polygon** for additional EVM compatibility and access patterns

This is why network setup is a core step in onboarding.

## Wallet UX and execution

Rabby and MetaMask remain core wallet options in the ecosystem. They are the bridge between user custody and smart-contract actions (approve, deposit, withdraw, trade, compound).

## Security reminder

Ethereum gives strong transparency and control, but user security still depends on wallet hygiene:

* protect seed phrase/private keys
* verify domains before signing
* check transaction details before approval
