SunSwap V2

Overview of SunSwap V2

SunSwap V2 is the second major version of SunSwap, TRON’s decentralized exchange (DEX) built for TRC‑20 tokens. It was launched with upgrades over V1 to provide more flexibility, improved routing, and better user experience. Key improvements include the ability to swap any two TRC‑20 tokens directly (without needing TRX as an intermediary) and automatic recommendations for optimal swap paths. :contentReference[oaicite:0]{index=0}

Liquidity providers (LPs) can deposit two tokens into liquidity pools and earn trading fees. There is also liquidity migration from older versions (V1 / V1.5) to V2. :contentReference[oaicite:1]{index=1}

Key Features & Enhancements

• 0.3% Trading Fee per swap, of which ~0.05% is used to buy back and burn SUN tokens (deflationary mechanism). :contentReference[oaicite:2]{index=2}
• Direct Token‑to‑Token Swaps (TRC‑20 ↔ TRC‑20) without using TRX as an intermediate token. :contentReference[oaicite:3]{index=3}
• Optimized Routing Protocol that suggests / uses best swap paths to minimize slippage and fees. :contentReference[oaicite:4]{index=4}
• Liquidity Migration from older SunSwap versions (V1 / V1.5) so LPs can move their positions to V2. :contentReference[oaicite:5]{index=5}
• Improved UI & UX including cleaner interface for swapping, pool analytics, and more intuitive workflows. :contentReference[oaicite:6]{index=6}
• No TRX requirement for intermediary swaps — you don’t need to route everything through TRX in many cases. :contentReference[oaicite:7]{index=7}
• Low Transaction Costs & Fast TRON Performance leveraging TRON’s high throughput and low gas fees. :contentReference[oaicite:8]{index=8}

Troubleshooting Common Issues

Unable to Connect Wallet / “SunSwap V2 not working”

• Ensure your wallet (e.g. TronLink) is unlocked and set to the TRON network. Wrong chain can block functionality.
• Clear browser cache, disable interfering browser extensions (pop‑ups blockers etc.).
• Make sure you're accessing the official SunSwap site / interface and not a phishing clone.

Swap Fails / High Slippage / Route Errors

• Set slippage tolerance appropriately, especially for less liquid token pairs.
• Check liquidity of the pool—low liquidity pools have high price impact.
• Check for direct TRC‑20 token pair support; sometimes swap paths may require intermediary tokens if direct pair is missing. But V2 improves many direct pairs. :contentReference[oaicite:9]{index=9}

Liquidity Provision / LP Token Problems / Migration Issues

• If you migrated LP from V1 or V1.5, verify that your LP tokens are recognized in V2 and that rewards or fees are correctly allocated. :contentReference[oaicite:10]{index=10}
• Ensure you provide both sides of the token pair in correct proportions; otherwise adding liquidity may fail or result in suboptimal LP share.

Fees / Cost Concerns

• Even though fees are relatively low, there is still network cost in TRON for transactions. Ensure you have some TRX to pay gas. :contentReference[oaicite:11]{index=11}
• Platform burns ~0.05% of each 0.3% trade fee for SUN token, which means LPs get ~0.25% net? Be aware of how fees‑to‑burn works. :contentReference[oaicite:12]{index=12}

Frequently Asked Questions (FAQ)

Q: What is the trading fee on SunSwap V2?

A: It is 0.3% per swap, of which 0.05% is used to buy back and burn SUN. The rest is distributed to liquidity providers. :contentReference[oaicite:13]{index=13}

Q: Do I need TRX as an intermediary when swapping two TRC‑20 tokens?

A: No. One key improvement in V2 is direct token‑to‑token swaps without needing TRX as a bridge. :contentReference[oaicite:14]{index=14}

Q: How do I migrate liquidity from V1 or previous versions?

A: SunSwap provides a liquidity migration feature that lets LPs move their pool positions from SunSwap V1 or V1.5 into V2. Check “Liquidity Migration” in the UI. :contentReference[oaicite:15]{index=15}

Q: Is SunSwap V2 audited / safe?

A: The smart contracts are open source. SunSwap asserts protocol improvements and security updates. However, always check community sources or audit reports from Sun.io / TRON ecosystem. :contentReference[oaicite:16]{index=16}

Q: Why is my liquidity or LP tokens not showing?

A: Could be because your LP tokens are still under V1 or V1.5 version, or your wallet address is not correctly detected. Toggle to V2 in the Liquidity section to see migrated pools. Also ensure you have claimed any pending migration or rewards. :contentReference[oaicite:17]{index=17}

Q: How low are the transaction costs on SunSwap V2?

A: Thanks to the TRON network and optimizations, swaps can cost less than a few TRX (often under ≈$0.30‑$1 depending on token and network load), especially for smaller trades. Recent “Lumina” reductions reduced many transaction fees significantly. :contentReference[oaicite:18]{index=18}
