# Supported Chains

Gotts Safe supports all 11 Uniswap-deployed chains for data queries and trading. Vault deployment (v1) targets Sepolia testnet for development, with mainnet launches on Ethereum and Base.

## Mainnet Targets (v1)

The v1 launch targets **Ethereum** and **Base** for mainnet deployment. Development and testing use **Sepolia** (Ethereum testnet) and local **Anvil** forks.

### Base-Specific Parameters

Base operates as an L2 with faster block times and lower gas costs, which affects several protocol parameters:

* **LVR** is approximately 2.5x lower on Base than Ethereum mainnet (sqrt(12/2) ≈ 2.45), making LP strategies more viable
* **Dynamic fees** use wider thresholds (sigma\_low=20%, sigma\_high=80%) on Base
* **am-AMM lookahead**: 36,000 blocks (equivalent to 7,200 on mainnet)
* **Gas costs** are 50-500x cheaper on Base, enabling frequent rebalancing strategies
