Pangolin is a decentralized exchange that runs on multiple blockchains, including Avalanche, Songbird, Flare, and Hedera. Launched in February 2021, it uses an automated market maker (AMM) model to facilitate the trading of crypto assets in a non-custodial manner, meaning users retain control of their funds. The platform is governed by its community through its native token, PNG, allowing token holders to influence the protocol's development and treasury management. Pangolin's mission is to provide a comprehensive and user-friendly DeFi hub that enables seamless trading, farming, staking, and bridging of assets across different blockchain networks.
