#Caldera $ERA @Calderaxyz The uniqueness of Caldera lies in its modular flexibility: each Rollup chain can independently choose its runtime environment (EVM or SolanaVM), preferred data availability layer (Ethereum mainnet, Celestia, or NEAR), and even specify native ERC-20 or ETH as the fee payment token. This high degree of customization means that projects can optimize transaction speed, cost efficiency, and security parameters according to their own needs.
