Why I changed Uniswap to Rhea Finance for my dApp (Spoiler: Dev life just got easier)

Hey fellow devs 👋,

I wanted to share a recent shift in my stack that's saved me time, gas, and headaches. For years, I built on Uniswap — solid protocol, great liquidity, no complaints. But when I started developing a high-frequency trading dApp, Ethereum's gas fees and Uniswap's integration complexity became a wall. Enter Rhea Finance on NEAR Protocol. Here's why I made the switch—and why you might consider it too.

😤 The Uniswap struggle

Uniswap's SDK is powerful, but integrating even basic features felt like running a marathon. For example, adding liquidity required:

  1. ERC-20 approvals (hello, gas waste!).
  2. Complex slippage calculations.
  3. Praying for no reverts mid-flow.

Here’s what that looked like in code:

And don't get me started on debugging failed txns costing $50 a pop.

🚀 Rhea Finance: "The simplicity you needed"

Ref's NEAR-based contracts cut steps (and costs) dramatically. Here’s the same liquidity addition on Ref:

Why this won me over:

  • No approvals: NEAR's account model handles permissions natively.
  • Atomic transactions: Bundle swaps, deposits, and stakes in one tx.
  • Gas costs under 0.01: Itested100iterationsforlessthan1cent.

No dependency on external routers. Less code = fewer bugs.

Rhea is the winner🏆

🛠️ Fetching Pool Data

Uniswap (The Graph Subgraph)
Requires querying a subgraph:

Rhea Finance (Direct Contract Call)
Query the contract directly via NEAR’s RPC:

Why the Rhea wins here:

  • No reliance on third-party indexers like The Graph.
  • Direct contract reads simplify data fetching.

⚠️ Caveats to Know

  1. The Rhea SDK is still evolving (official docs say it's "coming soon"), so compared to Uniswap's battle-tested SDK, it is less complete. But you can use NEAR's core SDK (near-api-js) today for all critical operations.

    a. Uniswap's SDK is like IKEA furniture: pre-packaged but rigid.

    b. Rhea + NEAR SDK is like a toolbox: fewer pre-built solutions, but you can craft exactly what you need.

  2. Smaller liquidity pools. Unfortunately, Uniswap's depth is unmatched, but NEAR's Rainbow Bridge lets you port Ethereum assets over.

🛠 When to Choose Ref

  • You're building cost-sensitive apps (e.g., microtransactions, social tokens).
  • You want atomic multi-action flows (e.g., swap + stake + mint NFT in one click).
  • You prefer Rust/Wasm's performance over Solidity.

📅 What You Can Do Today

  1. Create a NEAR wallet in 30 seconds: wallet.near.org.
  2. Bridge assets via Rainbow Bridge: Move ETH or USDC to NEAR in 5 minutes: rainbowbridge.app.
  3. Execute your first sub-cent swap: Trade NEAR for USDT here: ref.finance.

🏁 Final Takeaway

Uniswap is still king for Ethereum-native apps, but Rhea Finance saved me weeks of dev time (and my users from gas frustration and anxiety). If you're tired of Metamask popups and want to ship faster, give Rhea a shot—just double-check the contracts if the docs are behind.

Peace,
