How Enso Solves 73.5ETH in 116 Steps in One Transaction
A Head First DeFi Approach to Understand the Interaction Among Curve.fi, Balancer, Compound, and Reserve.
Enso is one of the leading solvers in the DeFi industry. During DappCon 2024, its founder, Connor Howe, announced the Enso Intent Engine, which helped Enso raise $4.2 million in funds.
During the presentation, Connor illustrated a complicated transaction to showcase Enso’s solver service. Today, let’s examine this transaction using the Head First DeFi way.
One Liner
Acting as a solver, Enso swaps the user’s 73.5 ETH for 216,661.863807 hyUSD, +276.533490 wcUSDCv3, and 80.362625 sDAI via Curve.fi, Compound, Balancer, and Uniswap.

Key Steps
Stage 1: Preparing.
Enso swaps the user’s ETH for USDC for future uses.
Step 4-5: Swap ETH for USDC for future use.
Stage 2: Getting DAI.
Enso swaps varying amounts of ETH through a series of tokens using platforms like Curve.fi, Uniswap, and Balancer, ultimately converting into DAI.
Step 9-26: Swap 0.5945826054 ETH -> frxETH -> WETH -> USDT -> crvUSD -> mkUSD -> FRAX -> USDC -> DAI, via Curve.fi
Step 27-46: Swap 0.5945826054 ETH -> stETH -> frxETH -> WETH -> ELON -> USDC -> PYUSDUSDC -> mkUSD -> USDe -> FRAX -> DAI, via Curve.fi and Uniswap.
Step 47-67: Swap 19.40115325 ETH -> stETH -> frxETH -> WETH -> USDC -> XAI -> FRAX -> USDe -> DAI, via Curve.fi and Uniswap.
Step 68-79: Swap 0.5945826054 ETH -> frxETH -> WETH -> USDT -> USDC -> DAI, via Curve.fi, Balancer, and Uniswap.
Step 80-87: Swap 3.339958598 ETH -> frxETH -> WETH -> USDT -> DAI, via Curve.fi and Uniswap.
Stage 3: Receiving hyUSD by staking derivative tokens.
Enso uses previous USDC and DAI to get derivative tokens, which are staked to receive the minted hyUSD being sent to the user.
Step 88-97: Swap DAI -> USDC -> crvFRAX -> eUSD3CRV-f, via Curve.fi.
Step 98-104: Swap eUSD3CRV-f -> cvxeUSD3CRV-f -> stkcvxeUSD3CRV-f, via Convex.
Step 105-109: Swap USDC -> cUSDCv3 -> wcUSDCv3, via Compound.
Step 111-113: Deposit sDAI, stkcvxeUSD3CRV-f, and wcUSDCv3 into Reserve for hyUSD.
Key Protocols
Enso: acting as the solver for the transaction to swap the user’s ETH for hyUSD. Enso Shortcuts is the DeFi automated strategy and action engine under the hood in the token flow chart.
Curve.fi: the intermediate exchange of ETH and other stablecoins.
Balancer: the intermediate exchange of stablecoins.
Convex: being built on top of Curve.fi. It allows liquidity providers (LPs) and CRV stakers to earn additional interest rewards without locking their tokens directly on Curve.
Compound: the DeFi lending protocol. When you deposit USDC assets into the Compound, like in this transaction, you receive cUSDC tokens.
Reserve: the DeFi platform that is designed to create stable, asset-backed currencies known as RTokens. hyUSD is an RToken issued through the Reserve Protocol.

Step-by-step Decoding
The table in the pictures below shows the detailed steps one by one.
Stage: The phases mentioned above.
Step: The steps are in the EigenTx token flow chart.
Mint or Burn: EigenPhi adds these steps to balance protocols' bookkeeping. Many protocols employ internal bookkeeping to save gas fees. Adding Mint or Burn to the chart would make it easier to grasp the internal mechanisms, like Uniswap’s adding and removing liquidity.
Amount: The token amount of the current step.
Token: The token of the current step.
Transfer from: The “from” protocol project of the current transfer step.
Transfer To: The “to” protocol project of the current transfer step.
Meaning: The DeFi meaning of the current steps.
