***UPDATE: If you are participating the 1inch Network gas refund promotion, you will receive a variable compensation for gas fees paid on a monthly basis.
If you are not a participant in the 1inch gas refund promotion, your gas fees cannot be refunded.
Due to the fundamental design an open blockchain like Ethereum, it is impossible to refund gas fees back to the sender. These fees for adding transactions to blocks are paid directly to miners on the ETH network (regardless of whether a transaction has been successful or failed).
Also, 1inch network never holds receives or custody of these funds, as it only searches for the best routes amongst decentralized protocols.
