Sun Swap
A decentralized exchange protocol built on the TRON blockchain — open, transparent, and built for everyone.
Our Mission
The team behind Sun Swap set out with a single clear goal: make decentralized trading genuinely accessible. Not just to developers or crypto-native power users, but to anyone holding TRC20 tokens who wants to swap without trusting a centralized party.
Open financial infrastructure matters. Sun Swap's protocol was designed from day one to operate without any platform commission — market makers keep 100% of the fees they earn. That's not a marketing claim. It's baked into the smart contracts.
Since launching on TRON, the Sun Swap platform has processed billions in trading volume across hundreds of token pairs. The protocol has gone through multiple iterations — V1, V2, and ongoing development — each version improving on liquidity depth, routing efficiency, and gas costs.
Technology
Sun Swap runs on an automated market maker model. Instead of an order book, liquidity providers deposit token pairs into pools. Prices are determined algorithmically — the familiar constant product formula (x × y = k) governs every swap.
Why TRON? Transaction finality is fast. Network fees are low. For a protocol built around high-frequency swapping, those things matter enormously. A swap on Sun Swap typically confirms in seconds, not minutes.
The Sun Swap protocol's smart contracts are publicly verifiable on TRONScan. The team has adopted conventions aligned with ERC-4626 vault standards where applicable, and tooling from the Forge testing framework has been used extensively during development. Liquidity tokens are standard TRC20 assets, meaning they integrate naturally with the wider TRON ecosystem — staking protocols, yield aggregators, and wallets all work without custom adapters.
V2 introduced multi-hop routing. If no direct TRX/TOKEN pool exists, the protocol automatically routes through intermediate pairs to find the best execution price for you.
Our Approach
Decentralized protocols live or die by trust. The Sun Swap platform publishes all contract addresses, audit reports, and developer documentation publicly. Nothing is hidden behind a paywall or a terms-of-service click-wrap.
The approach to governance has evolved. SUN token holders participate in key decisions — liquidity incentives, parameter changes, and protocol upgrades go through on-chain governance via SUN DAO rather than unilateral team decisions. This isn't decoration. Token holders have voted to adjust fee tiers, allocate incentive budgets, and shape the roadmap.
On fees: the protocol charges a flat 0.3% per swap. That entire fee flows to liquidity providers. The Sun Swap platform itself takes zero cut. Compare that to centralized exchanges where spread, withdrawal fees, and trading fees stack up quietly.
Security is treated as an ongoing process, not a checkbox. Contracts have been audited by independent firms, and the team runs a bug bounty program. Responsible disclosure is taken seriously. Visit the support page if you have a security concern or question.
The Ecosystem
Sun Swap doesn't operate in isolation. It's part of the broader sun.io ecosystem, which includes stablecoin swapping (Curve-style pools), lending, and yield products. The Sun Swap platform serves as the primary spot-trading layer for TRC20 tokens within this ecosystem.
SunPump, launched in 2024, added a token launchpad directly connected to Sun Swap liquidity. New tokens created on SunPump automatically graduate to Sun Swap pools once they hit a bonding curve threshold. That integration reduced friction for new projects considerably.
The SUN token (ticker: SUN) is the native governance and utility token. It's used for voting in SUN DAO, for staking rewards, and as part of the protocol's tokenomics. The team has run multiple buyback-and-burn campaigns — 50 phases completed as of early 2026 — removing SUN from circulating supply over time.
Liquidity providers who want deeper analytics can explore pool stats on the Scan section of the platform, or connect via the Sun Swap interface directly.
Transparency & Governance
Every major protocol parameter is subject to governance. That includes emission rates, supported token lists, and fee configurations. Proposals go through a discussion period before moving to on-chain vote.
The Sun Swap team publishes developer documentation (PDF) and maintains integration guides for third-party protocols that want to build on top of Sun Swap liquidity. ERC-4626 compatibility notes and Forge-based test suites are referenced in those docs for developers building vault integrations.
Whistleblower protections are in place for anyone reporting bad actors or vulnerabilities through official channels. Details are in the Terms of Service linked from the main interface.
Want to get involved? The Sun Swap community is active on Telegram and X (Twitter). Governance discussions happen in the open. You don't need permission to participate — just SUN tokens and a TRON wallet.
