Case Study: Public Mint achieves accessible, FDIC-backed, dollar-native instant-settlement blockchain banking with Hyperledger Besu

Public Mint develops a platform with Hyperledger Besu to make blockchain’s financial benefits accessible to everyone

Public Mint, a fintech with offices in the US, UK and Europe, set out to make blockchain banking accessible to mainstream users by removing crypto complexity and risk. The company needed a platform that could mint one-to-one synthetic dollars fully collateralized by funds held at FDIC‑insured custodians, provide instant settlement between wallets, and offer a simple path into DeFi — and chose Hyperledger Besu (under the Hyperledger umbrella) as its enterprise-grade, Ethereum‑compatible technology stack.

Using Hyperledger Besu, Public Mint launched a web wallet and the EARN program that run natively in US dollars (no Ether), enabling instant, low‑cost on‑chain transfers and pooled DeFi/CeFi yield opportunities. Since the July 2020 launch Public Mint has created more than 3,800 wallet addresses, holds over USD $2.9 million on‑chain, and has validated 28,000+ transactions; EARN can deliver example APYs of 6–8% versus ~0.06% at average US banks — all built on Hyperledger Besu.
