EnergySwap
Trade excess energy peer-to-peer on the blockchain.
The problem EnergySwap solves
EnergySwap enables individuals with excess renewable energy (e.g., from solar panels) to sell it directly to others, bypassing traditional utilities. It simplifies energy trading, reduces costs, and promotes sustainability using the Sepolia Ethereum testnet for secure, transparent transactions.
Challenges we ran into
One big hurdle was a MetaMask "insufficient funds" error during testing: my wallet had 0.05 ETH, but a 2 ETH transaction required 8 ETH total with gas. I debugged the gas estimate (36M gas was too high), lowered the test price to 0.01 ETH, and funded the wallet with Sepolia test ETH from a faucet. Adding a manual gas limit (100K) also helped stabilize it.
