SUN Description
Overview
Sun [New] (also referred to as "Sun Token" / "SUN (New)") (SUN) is the native token of SUN.io, an integrated DeFi platform on TRON (TRC-20).
SUN.io combines a decentralized exchange (SunSwap), a token launchpad (SunPump), a perpetuals product (SunX, formerly SunPerp), and a governance layer (SUN DAO), all operating within the TRON ecosystem founded by Justin Sun. As of 2026-08-31, SUN traded near $0.0165 with a market capitalization of roughly $318 million.
Value Proposition
SUN's value accrual is anchored in a buyback-and-burn model funded directly by protocol revenue rather than token emissions alone.
100% of revenue from SunPump and SunX, plus a portion of SunSwap trading fees, is used monthly to buy back and burn SUN, tying token scarcity to platform usage rather than a fixed supply schedule. SUN.io's DeFi platform carried roughly $640 million in total value locked with about $440 million in 7-day trading volume as of late July 2026.
Token Basics
SUN functions as both a governance and utility token, primarily through its vote-escrow "veSUN" mechanism.
- Holders lock SUN to receive veSUN, a non-transferable voting-power certificate.
- veSUN holders receive a liquidity-mining speed boost and 50% of trading fees generated in stablecoin swap pools.
Tokenomics
SUN has a total supply of approximately 19.9 billion tokens, of which about 19.22 billion were in circulation as of 2026-08-31.
- Disclosed allocation: 40% liquidity mining, 25% community treasury, 20% staking rewards, 15% ecosystem growth.
- Net supply is mildly deflationary: a monthly buyback-and-burn program has completed 51 consecutive rounds since December 15, 2021, permanently removing approximately 678.5 million SUN (about 3.4% of total supply).
- A supply-inflation risk indicator sits at a mildly negative EMA (-0.40%), consistent with net deflation.
Launch & Funding
SUN originally launched in September 2020, as SUNOLD, through a Genesis Mining program in which users staked TRX to earn SUN, rather than a traditional ICO or IEO.
In May 2021 (2021-05-24/26), the token's total supply was split 1:1000, from roughly 19.9 million to 19.9 billion tokens, and migrated to a new contract — the "Sun [New]" contract tracked today — with market capitalization held constant through the split. That contract was deployed 2021-05-24, nearly eight months after SUN's original 2020 launch.
Blockchain & Consensus
SUN is deployed on the TRON blockchain as a TRC-20 token, at contract address TSSMHYeV2uE9qYH95DqyoCuNCzEL1NvU3S.
It runs atop TRON's existing network infrastructure rather than a dedicated chain or validator set of its own.
Team
SUN.io's driving force is Justin Sun, founder of the TRON blockchain (2017), rather than a publicly disclosed corporate team.
Justin Sun is also founder/advisor of the Poloniex and HTX (formerly Huobi) exchanges. Per the project's own framing, SUN carries "zero VC investment, zero PE investment, no pre-mining or reserve for the team" and is described as operated by the community through open-source smart contracts.
Issuing Organization
SUN.io, described as TRON's flagship integrated DeFi platform, maintains and develops the SUN token, operating within the broader TRON ecosystem founded by Justin Sun.
Its product suite spans SunSwap (DEX), SunPump (launchpad), SunX (perpetuals), and the SUN DAO governance layer.
Governance
SUN is governed on-chain through a vote-escrow model in which holders lock SUN for veSUN, a non-transferable voting-power token.
veSUN holders vote on governance proposals and on liquidity-pool gauge weights that direct SUN emissions, and holders above a set veSUN threshold can submit proposals themselves. The formal governance body, SUN DAO, was established by TRON DAO as "the official SUN community governance committee," launched July 31, 2024.
Roadmap
SUN.io launched a public buyback-and-burn dashboard on April 22, 2026, letting users track how protocol revenue converts into token burns.
In August 2026, TRON's flagship tokens JST, SUN, BTT, and WIN jointly rolled out upgraded buyback-and-burn mechanisms, reported as TRON entering a "deflationary era."
Security
SunSwap, the SUN.io DEX component, holds a CertiK Skynet composite security score of 81/100 (Grade A), though CertiK states it has not itself conducted a formal audit.
- A third-party audit report exists, referenced as produced by the SlowMist Security Team.
- CertiK flags no bug bounty program from any provider and a team not independently KYC-verified.
- DEX liquidity relative to market cap is about 3%, rated LOW risk.
- Roughly 31,903 holder addresses were recorded as of 2026-08-31.
Frequently Asked Questions
What is Sun [New] (SUN)?
Sun [New] (SUN) is the native TRC-20 token of SUN.io, an integrated DeFi platform on the TRON blockchain combining a DEX (SunSwap), a launchpad (SunPump), a perpetuals product (SunX), and governance (SUN DAO). As of 2026-08-31 it traded near $0.0165 with a market cap of about $318 million.
What blockchain does SUN run on?
SUN is deployed on the TRON blockchain as a TRC-20 token, at contract address TSSMHYeV2uE9qYH95DqyoCuNCzEL1NvU3S. It uses TRON's existing network infrastructure rather than operating its own separate chain or validator set. This current contract was deployed on 2021-05-24, following a 1:1000 supply redenomination from the original SUN token.
Is SUN a governance token?
Yes. SUN is both a governance and utility token: holders lock SUN for veSUN, a non-transferable voting-power certificate used to vote on governance proposals, direct liquidity-pool gauge weights, and earn a share of stablecoin swap-pool trading fees. Holders above a set veSUN threshold can also submit governance proposals themselves.
How does SUN's buyback-and-burn program work?
100% of revenue from SunPump and SunX, plus a portion of SunSwap trading fees, is used monthly to buy back and burn SUN. The program has run 51 consecutive monthly rounds since December 15, 2021, removing about 678.5 million SUN (roughly 3.4% of total supply).
What is SUN's total and circulating supply?
SUN's total supply is approximately 19.9 billion tokens, with about 19.22 billion in circulation as of 2026-08-31. This reflects a 2021 redenomination that split the original ~19.9 million SUNOLD supply 1:1000. Net supply is mildly deflationary due to an ongoing monthly buyback-and-burn program.
Who founded SUN.io?
Justin Sun, founder of the TRON blockchain (2017), is the driving force behind SUN.io. The project states it received zero VC or PE investment and no team pre-mine, describing itself as community-operated through open-source smart contracts. Justin Sun is also founder or advisor of the Poloniex and HTX cryptocurrency exchanges.
Has SUN been audited?
SunSwap holds a CertiK Skynet composite score of 81/100 (Grade A), but CertiK explicitly states it has not conducted its own audit; a separate third-party audit report attributed to the SlowMist Security Team exists. No bug bounty program is in place, and the team is not independently KYC-verified.
Why did SUN's supply change from millions to billions?
In May 2021, SUN's total supply was split 1:1000, rising from roughly 19.9 million to 19.9 billion tokens, migrating to a new contract deployed 2021-05-24. Market capitalization was held constant through the split, so existing holders' USD value was not diluted.
