Aave Deposit Gas Fee: Live Cost to Supply on Ethereum
Right now, to deposit into Aave on Ethereum mainnet costs about $0.044 at the standard gas price of 0.081 gwei.
Supplying an asset to a lending protocol such as Aave updates interest indexes, mints interest-bearing receipt tokens and moves your deposit. A typical supply transaction uses about 180,000 to 260,000 gas. ERC-20 deposits also need an approval the first time.
How the cost is calculated
Fee = gas used × gas price × ETH price. With the current standard price: 220,000 gas × 0.081 gwei = 0.00001780 ETH, which is $0.044 at $2,492 per ETH. Across the typical range of about 180,000 to 260,000 gas, the standard cost is between $0.036 and $0.052.
How to pay less
- Lending positions are long-lived. Paying a little more gas on entry matters less than the yield over months.
- Borrowing, repaying and withdrawing each cost similar amounts of gas.
- Check the cheapest hours to transact and avoid known demand spikes.
