Buy & Swap Sun [New] (SUN)

Tron's DeFi hub

SUN.io's official site describes it as the leading DeFi protocol on Tron: swap, stake, earn, liquidity mining and governance in one platform. Its documentation is organised around trading, liquidity and risks, with a getting-started section covering core concepts.

The platform's trading side is SunSwap, documented in three versions — V2, V3 and V4 — plus a universal router that routes trades across them. This versioning mirrors how decentralised exchanges evolve: each new version changes how liquidity is provided and priced, while older versions keep running.^{[1], [2], [3]}

Stablecoin tools: SunCurve and the PSM

Alongside ordinary token swaps, the documentation covers SunCurve, a specialised exchange for stablecoins and similarly priced assets, where low-slippage trading matters most. It also documents a PSM — a peg stability module — which lets approved stablecoins be exchanged at a fixed rate to help maintain a peg.

A SUN-HTX section of the documentation covers the token's relationship with the HTX exchange, and a trading-fees page documents how fees work across the platform's products.^{[4], [5], [6], [7]}

Liquidity and mining

SUN.io's documentation includes a liquidity section explaining how to choose a liquidity solution and how to create liquidity, across SunSwap V2, V3, V4 and SunCurve. Liquidity mining programmes let providers earn rewards on top of trading fees.

The documentation also includes a dedicated risks section — a good sign, since providing liquidity exposes users to impermanent loss and smart-contract risk, and the platform puts those considerations in writing.

For developers, the docs ship an API reference alongside the user guides, so the same endpoints that power the interface can be integrated into other Tron applications. That openness is part of why SUN.io functions as shared infrastructure for the network rather than a single closed product.^{[8], [9], [10]}

Where SUN fits

SUN is the platform's token, associated with governance and the platform's incentive programmes. Within SUN.io, the token is used to align the community that provides liquidity and uses the exchange with the platform's development.

Because SUN.io is built on Tron, SUN exists as a Tron token, and using the platform's products means interacting with Tron-based smart contracts through a compatible wallet.^{[1], [9], [11]}

Risks and limits to understand

SUN.io's own documentation directs users to a risks section, which is the right starting point. Swapping, providing liquidity and joining mining programmes each carry distinct risks — price movement, impermanent loss and contract risk — that rewards do not cancel out.

The platform's products are tied to the Tron ecosystem, so SUN's usefulness tracks the activity of that ecosystem. The documentation's API reference and versioned swap contracts make the platform's mechanics inspectable for anyone who wants to verify them.^{[10], [2], [8]}

Tron DeFi's share of on-chain activity

SUN.io is the established DeFi platform on Tron with a full suite of swap and stablecoin products. How its activity evolves relative to DeFi on other chains is UNKNOWN from official sources.
