An EVM-compatible blockchain, SKALE Calypso Hub focuses on NFTs with gasless sFUEL transactions, fast finality, and pooled security on the SKALE Network.
SKALE Calypso Hub is a mainnet EVM chain in the SKALE Network purpose-built for NFTs, gaming, and digital media, offering gasless user transactions via sFUEL covered by the chain and pooled validator security. Primary use cases include zero-fee NFT minting/marketplaces, on-chain game economies and item trading, creator drops, and high-frequency microtransactions requiring fast finality and high throughput. It supports standard Ethereum tooling, wallets, and bridging for seamless asset movement.
Calypso Hub is unique for zero end-user gas (avg user gas cost ≈ $0 in sFUEL), near-instant confirmations (~2s block time), and high throughput in the thousands of TPS (benchmarked >2,000 TPS per SKALE chain) under shared, pooled security. Its app-chain model eliminates gas wars and enables predictable dApp costs, with activity optimized for high-volume NFT mints and game actions without congestion versus L1s or shared-rollup networks. EVM compatibility plus native SKALE features like on-chain file storage and fast interchain messaging to Ethereum deliver a Web2-speed UX.
