First published 3 September 2020, the day after genesis mining started. Expanded in October 2026 so the old unit is not described as the new one, and so a swap site is not described as TRON itself. SUN is a TRON token. Justin Sun is the person most associated with the chain it sits on. sun.io is a site for swaps and pools. The token is not a share of TRON. What is TRON (TRX)? is the chain. TRX pays a TRON fee. SUN does not. What is Curve (CRV)? is a different protocol the project compared itself to. SUN is not CRV.
Genesis mining started on 2 September 2020. People staked TRX and the contract paid SUN. The whitepaper set the supply at 19,900,730 and said there was no pre-mine and no team allocation. On 26 May 2021 the project redenominated. One old SUN became 1,000 new SUN. The count went from 19,900,730 to 19,900,730,000. The market value of a holding was not meant to change. Old tokens were renamed SUNOLD. This page means the new unit. A balance still labeled the old way is a thousand times off if you read it as the new coin.
A pool on sun.io can return fewer of the coins you deposited when the price moves. That is the trade. This page will not walk through a pool or a stake. A SUN address is a TRON address. It is not an Ethereum address. What if you send crypto on the wrong network? Nothing here is an instruction to mine, to swap SUNOLD, or to buy SUN.
