Circle's USD Coin (USDC), integrated with the Hedera network, offers a regulated, fiat-backed stablecoin pegged to the US dollar. This collaboration allows USDC to be minted natively on Hedera, leveraging the network's fast settlements (around 3-5 seconds), low transaction fees (typically $0.0001 to $0.001, paid in HBAR), and high scalability.
USDC on Hedera provides a trusted, stable, and reliable bridge for decentralized finance (DeFi) applications and end-users on the Circle and Hedera networks. Circle's increasingly popular suite of developer APIs offers full support for USDC on Hedera, facilitating its use in various applications including both payments and micropayments.
With USDC, enterprises and financial institutions have access to cross-platform liquidity and secure cross-border transactions. It’s currently used to facilitate payments and micropayments within applications such as Calaxy, Dropp, and Scintilla as well as to in support of numerous DeFi, NFT projects, and network bridge applications building on Hedera including SaucerSwap and Hashport.
Blockchain for Energy (B4E) is a non-profit, member-led consortium dedicated to driving digital transformation within the energy sector. Comprising major energy companies including Chevron, ExxonMobil, and Repsol, B4E was established to collaboratively develop and implement blockchain-based solutions that can enhance efficiency, reduce costs, and increase transparency across the industry.
The consortium's flagship product is the B4ECarbon platform, an advanced digital measurement, reporting, and verification (dMRV) solution. This platform integrates AI and IoT with distributed ledger technology to provide a secure and auditable system for managing emissions data. It enables energy operators to track, report, and verify their environmental performance in near real-time, helping to prevent greenwashing and ensure compliance with global standards. The B4E Network & Platform, built on Hyperledger FireFly, serves as the foundational layer connecting all of the consortium's solutions in a decentralised environment governed by its members.
The B4ECarbon platform is built on the Hedera public network, and has been a member of the Hedera Governing Council since June 2025.
The Managed Guardian Service (MGS) is a SaaS platform built on the open source Hedera Guardian, designed to simplify the creation, management, and verification of digital emissions and carbon offset tokens. It leverages Hedera’s public ledger to ensure that each digital environmental asset, from carbon credits to Renewable Energy Certificate is auditable, traceable, and reproducible, reducing fraud and enhancing sustainability market integrity.
MGS builds on the Guardian’s Policy Workflow Engine and W3C-backed Web3 integrations, offering flexible onboarding (UI and API), real time indexing, analytics, and full lifecycle oversight for tokenised environmental assets. Operated by Envision Blockchain and supported by the Hedera Foundation and Swirlds Labs, MGS enables organisations to streamline carbon accounting, uphold transparent methodologies, and scale climate solutions securely on Hedera’s fast, low energy network.
Bonzo Finance is an open-source, non-custodial lending and borrowing protocol built on the Hedera network. It is a fork of the popular Aave v2 protocol and is designed to serve as "The Liquidity Layer" for the Hedera DeFi ecosystem.
The core of Bonzo Finance's service is its decentralized platform that allows users to lend and borrow a variety of cryptocurrencies, with a focus on HBAR, native USDC, and other Hedera ecosystem assets. Users supply crypto to the protocol to earn interest, provide liquidity, and as collateral for loans.
Bonzo Finance also offers "flash loans," which are uncollateralized loans that must be repaid within a single transaction. It has its own governance token, $BONZO.
Bonzo Finance is built on the Hedera Smart Contract Service, and it is designed to be fully compatible with the Hedera Token Service (HTS). It also utilizes the Hedera Consensus Service (HCS) for its verifiable points and rewards program.
