Polter Finance is a decentralized, non-custodial lending and borrowing platform that operates on the Fantom chain. It was developed in response to the shutdown of the $GEIST platform, using similar smart contracts but with key improvements. One significant enhancement is the disabling of flash loans, reducing risks for users. Polter allows depositors to earn a share of the interest generated from borrowers. The platform aims to offer a secure and efficient alternative for decentralized finance (DeFi) enthusiasts.
