According to @EmberCN, Ethereum mainnet gas price dropped to about 0.1 gwei, putting a simple L1 ETH transfer near $0.02 on Dec 2, 2025, source: @EmberCN on X. At 0.1 gwei, a 21,000-gas transfer costs about 0.0000021 ETH because total fee equals gas used times gas price, source: Ethereum.org documentation. @EmberCN also notes this level is the lowest since the 2020 DeFi Summer and even below some L2 fees, so traders can route swaps or contract deployments on L1 when quoted L2 all-in fees are higher, source: @EmberCN on X and Ethereum.org documentation.
