The decentralized finance (DeFi) space continues to evolve rapidly, with new yield farming and liquidity mining opportunities emerging across various blockchain ecosystems. One of the most talked-about projects in 2020 was Yearn.finance (YFI)—a community-driven DeFi protocol that sparked massive interest due to its fair launch model and high returns. Riding this wave of enthusiasm, Tron (TRON) founder Justin Sun announced the launch of SUN, a meme-inspired token on the Tron blockchain designed to replicate YFI’s success through a community-powered genesis mining event.
This article explores the concept behind SUN, explains how TRX staking works for SUN mining, and provides a step-by-step guide to participating in this high-profile liquidity mining initiative—all while integrating key insights into DeFi trends and blockchain innovation.
Understanding YFI: The Inspiration Behind SUN
Before diving into SUN, it's essential to understand what YFI is and why it became such a phenomenon in the crypto world.
YFI, the governance token of yearn.finance, was launched without any pre-mine, venture capital funding, or team allocation—making it one of the first truly decentralized and community-owned DeFi projects. Users earn YFI by providing liquidity or staking stablecoins like DAI, USDC, and USDT in yearn’s vaults. These vaults automatically optimize yield by moving funds across lending platforms such as Aave and Compound.
One of the reasons YFI gained so much traction is its extremely limited supply—only 30,000 tokens were ever minted. Combined with intense demand and high staking rewards, YFI’s price surged dramatically, reaching an all-time high of nearly $44,000 per token in August 2020. This meteoric rise captured global attention and inspired numerous copycat projects across different blockchains—including Tron’s SUN.

Introducing SUN: Tron’s Community-Driven Meme Token
Announced by Justin Sun on September 1, 2020, SUN is Tron’s answer to YFI—a fully community-governed token built on the Tron network with no pre-mine, no private sale, and no team reserves. Like YFI, SUN aims to incentivize liquidity provision and engagement within the Tron DeFi ecosystem.
Here are the core features of the SUN project:
- Total Supply: 19,900,730 SUN tokens
- Genesis Mining Start Time: September 2, 2020, at 21:00 (UTC+8)
- Zero VC Involvement: No venture capital, no private investors, no early allocations
- Open & Transparent: Powered entirely by open-source smart contracts and community participation
The primary mechanism for earning SUN is staking TRX during the genesis mining phase. This process not only distributes tokens fairly but also strengthens the overall liquidity of the Tron network.
Early Bird & Regular Mining Phases
The mining schedule was structured in two key phases:
Early Bird Phase (September 2 – September 15)
- Exclusive 10% bonus rewards for early participants
- Only TRX staking accepted during this period
Regular Mining Phase (Starting September 16)
Expanded support for staking multiple Tron-based assets:
- TRX
- BTT (BitTorrent Token)
- JST (JUST Stablecoin)
- WIN (WINk)
- USDJ (Tron’s algorithmic stablecoin)
- USDT (Tron version)
Additionally, a portion of the mining rewards was allocated to liquidity providers on JustSwap, Tron’s native decentralized exchange (DEX), further boosting ecosystem growth by incentivizing trading pair liquidity.
Mining Reward Distribution
To ensure long-term sustainability and community development, the regular mining pool allocated rewards as follows:
- TRX Pool: 30%
- JST Pool: 10%
- USDJ Pool: 10%
- BTT Pool: 5%
- WIN Pool: 5%
- Community Projects & Liquidity Pools: 40%
This distribution model highlights Tron’s focus on nurturing its broader DeFi ecosystem rather than concentrating rewards on a single asset.
Step-by-Step Guide to Participating in SUN Genesis Mining
Participating in SUN mining requires interacting with Tron-based decentralized applications (dApps). Below is a clear, beginner-friendly walkthrough.
Step 1: Set Up a Compatible Wallet
You’ll need a wallet that supports Tron dApps. Recommended options include:
- TronLink (officially developed by Tron)
- TokenPocket
- imToken
- BitKeep

Why use TronLink? It offers seamless integration with Tron dApps, built-in browser functionality, and enhanced security. Avoid third-party links or referral codes—focus on official sources only.
Step 2: Transfer TRX to Your Wallet
Move TRX from an exchange or another wallet to your chosen Tron-compatible wallet. Ensure you leave a small amount of TRX uncommitted to cover transaction fees (bandwidth or energy costs on the Tron network).
Step 3: Access the SUN Mining dApp
Open your wallet’s built-in browser (e.g., in TronLink, tap “Browser”) and navigate to the official mining platform:
sun.market
⚠️ Always verify URLs manually. Never click on untrusted links shared in groups or social media.
Step 4: Begin Staking
Once on the site:
- Click on “Genesis Mining”
- Enter the amount of TRX you wish to stake
- Confirm the transaction
- Input your wallet password to authorize
Your TRX is now locked in the mining pool, and you begin accruing SUN rewards immediately.
Step 5: Unlocking Your Staked TRX
After the mining period ends (initially set for September 17), return to sun.market, go to the Genesis Mining section, and select “Unlock” to retrieve your staked TRX.
Note: There is a cooldown period—you cannot withdraw until the designated unlock time.
Why Did SUN Gain Immediate Traction?
Within just three and a half hours of launch, over 3.6 billion TRX had been staked—equivalent to about 3.58% of total supply and 5.04% of circulating supply. This overwhelming response can be attributed to several factors:
- Hype Around YFI: Investors sought early access to a “YFI-like” opportunity with potentially lower entry barriers.
- Fair Launch Model: No pre-sale meant equal opportunity for all participants.
- Strong Network Effect: Tron’s existing user base provided instant liquidity and engagement.
- Speculative Momentum: Early stakers anticipated high ROI based on scarcity and demand dynamics.
However, experts caution against viewing such projects purely through a profit lens. While yield farming can generate returns, it also carries risks—including smart contract vulnerabilities, impermanent loss, and market volatility.
Frequently Asked Questions (FAQ)
Q: Is SUN a scam or a legitimate project?
A: SUN was officially launched by Justin Sun and built on transparent smart contracts. While it carries speculative risk like any DeFi project, it is not inherently fraudulent. Always conduct independent research before investing.
Q: Can I stake other tokens besides TRX?
A: Yes—but only during the regular mining phase. Initially, only TRX was accepted. Later phases allowed staking of BTT, JST, WIN, USDJ, and USDT on the Tron network.
Q: What happens after I unlock my TRX?
A: Once unlocked, your TRX becomes available for withdrawal or reuse in other dApps. Any earned SUN tokens will be distributed according to the mining rules.
Q: How are SUN rewards calculated?
A: Rewards are distributed proportionally based on your share of the total staked TRX during each epoch. The more TRX staked network-wide, the lower individual yields may become over time.
Q: Where can I trade SUN tokens?
A: After distribution, SUN became available on various decentralized exchanges like JustSwap and centralized exchanges that list Tron-based tokens.
Q: Should I buy YFI or participate in SUN mining?
A: Buying YFI on secondary markets often means paying premium prices. Participating in mining allows you to earn tokens at near-zero cost if done early—making it a more capital-efficient strategy for many users.

Final Thoughts
The launch of SUN exemplifies how fast-moving innovation drives engagement in blockchain ecosystems. By combining elements of meme culture, decentralized governance, and yield farming incentives, Tron created a compelling narrative that attracted massive participation.
While the initial hype has subsided, SUN remains a case study in how communities can rally around fairly launched tokens—and how staking native assets like TRX can fuel ecosystem growth.
As DeFi continues to expand beyond Ethereum into high-throughput networks like Tron, understanding mechanisms like liquidity mining, token distribution, and decentralized governance will be crucial for anyone navigating the future of finance.
