JUST Foundation is an organization focused on developing decentralized financial (DeFi) solutions on the TRON network. It provides a range of financial tools, including lending, stablecoin issuance, staking, and energy rental solutions. The foundation contributes to the governance and development of the JUST ecosystem, which includes platforms such as JustStable, JustLend DAO, and JustCrypto. ^{[1] [2] [3]}

Overview

The JUST ecosystem consists of decentralized finance solutions, primarily focusing on stablecoin issuance, lending services, and cross-chain interoperability. Its main products include:

• JustStable – A decentralized stablecoin system utilizing USDJ, a TRON-based stablecoin pegged to the US dollar.
• JustLend DAO – TRON's first official lending platform, where users can borrow, lend, and earn interest on digital assets.
• sTRX Staking – A staking program that allows TRX holders to earn additional yields through TRON Stake 2.0.
• Energy Rental – A service designed to reduce transaction costs on TRON by enabling users to rent Energy instead of burning TRX.
• JustCrypto – A cross-chain asset platform that facilitates token swaps and liquidity bridging across different blockchain ecosystems. The ecosystem operates with two primary tokens:

1. JST – The governance token used for decision-making and platform improvements.
2. USDJ – A stablecoin backed by collateralized debt positions (CDPs), maintaining a 1:1 peg with the US dollar. JST serves as the governance token, allowing holders to vote on protocol upgrades and risk management policies. USDJ is a stablecoin backed by collateralized debt positions (CDPs) and maintains a 1:1 peg with the US dollar through automated mechanisms. Mining and staking mechanisms provide incentives for ecosystem participants, while token burns help manage supply.

JST Airdrop Program

JUST Foundation introduced an airdrop program to distribute JST tokens to TRON (TRX) holders over a two-and-a-half-year period. The initiative was structured to allocate 10% of the total JST supply to eligible addresses through periodic distributions.

The first snapshot for the airdrop was recorded at 00:00 UTC on May 20, 2020, with an initial allocation of 217,800,000 JST to TRX holders possessing at least 100 TRX at the time of the snapshot. The distribution followed a predefined schedule:

1. June 2020 – May 2021: 237,600,000 JST (2.4% of total supply)
2. June 2021 – May 2022: 257,400,000 JST (2.6% of total supply)
3. June 2022 – October 2022: 277,200,000 JST (2.8% of total supply) Monthly snapshots were taken on the 20th at 00:00 UTC, ensuring consistent allocation to TRX holders. The airdropped JST was distributed to supported wallets and exchanges, including Poloniex, KuCoin, Bitpie, and Atomic Wallet. ^{[1] [2] [3] [4] [6] [11]}

History

JUST Foundation was established to address the need for decentralized financial solutions within the TRON ecosystem. In 2020, it introduced JustStable and the USDJ stablecoin, allowing users to generate a TRON-based stablecoin through collateralization. That same year, JustSwap was launched as a decentralized exchange (DEX) to facilitate token trading within the TRON network. The introduction of JustLend followed, providing lending and borrowing options for TRON users.

By 2021, JustSwap underwent a rebranding after being acquired by SUN.io, transitioning into SunSwap to further integrate with the TRON DeFi landscape. That year also saw the launch of JustLink, a decentralized oracle service that supplies price feeds for smart contracts. In 2022, JustLend transitioned to a decentralized governance model and was renamed JustLend DAO. Additionally, the JST token was recognized as an authorized digital currency in the Commonwealth of Dominica, providing regulatory legitimacy.

In 2023, the foundation expanded its staking and lending features, launching new markets within JustLend DAO, including sTRX and wstUSDT, which enabled users to leverage their assets for borrowing and staking. Revenue from the stUSDT protocol was also directed toward JST/TRX liquidity pools to support the ecosystem. By 2024, JST was listed on MercadoBitcoin, Brazil’s largest cryptocurrency exchange. JUST Foundation also participated in blockchain partnerships and continued the expansion of JustLend DAO. ^{[1] [7] [8] [9] [10]}

Governance

The JUST ecosystem operates under a decentralized governance model, where JST holders participate in decision-making processes, including:

• Adjusting risk parameters for lending and stablecoin issuance.
• Voting on protocol upgrades and economic policies.
• Managing liquidity strategies through the JustLend DAO governance system.

JUST Foundation’s smart contracts undergo security audits to ensure system integrity and prevent vulnerabilities. The transition of JustLend to a DAO introduced governance mechanisms aimed at enhancing transparency and security. The ecosystem also incorporates liquidation mechanisms within its lending protocols to mitigate risks associated with collateralized borrowing.

Technical Architecture

JUST Foundation's ecosystem is built on the TRON blockchain and utilizes smart contracts to automate financial operations. The TRON Virtual Machine (TVM) supports contract execution, enabling decentralized applications (DApps) within the ecosystem. The infrastructure includes mechanisms for staking, lending, collateralized stablecoin issuance, and resource management through Energy rental.

Key Features

• Smart Contract Automation – Transactions are executed automatically through smart contracts without requiring third-party intermediaries.
• Cross-Chain Interoperability – JustCrypto enables asset transfers between TRON and other blockchain networks.
• Energy Optimization – The Energy Rental system provides a way to minimize transaction costs by allowing users to rent Energy instead of burning TRX.
• Decentralized Lending – JustLend DAO supports multiple token markets, providing liquidity and yield opportunities. JUST Foundation continues to develop its DeFi ecosystem within TRON, offering financial products and governance mechanisms. ^{[1] [5]}
