Stellar
Stellar is a fast, low-cost, open-source blockchain built for payments, asset issuance, and — since the launch of Soroban smart contracts — decentralized finance. Its native asset is XLM, and it hosts native USDC, making it a low-fee home for stablecoin yield and fixed-income products like Spield.
Stellar is a payments-focused Layer-1 blockchain known for sub-cent fees and fast settlement. With Soroban smart contracts, it now supports a growing DeFi ecosystem including lending (Blend), AMMs, and fixed income (Spield).
