Transaction Operations for a Common Token Transfer

This article compares ERC20, ERC777, ERC1363, and ERC2612 token standards on Ethereum, explaining how ERC20's approve+transfer two-step flow increases transaction count and gas costs and how ERC777, ERC1363, and ERC2612 address this by enabling single-transaction flows or operator/signed approvals; it concludes ERC1363 and ERC2612 are preferable for minimizing transactions and improving gas efficiency.
