Several standards and protocols are essential for ensuring interoperability in cross chain token development. ERC-20 and ERC-721 are widely recognized token standards for Ethereum, while BEP-20 is used on the Binance Smart Chain. Cross chain token developers often rely on standards like Polkadot's Parachain, Cosmos's IBC (Inter-Blockchain Communication), and Atomic Swaps to facilitate communication between different blockchains. Adhering to these standards ensures that tokens can be transferred and interacted with across diverse blockchain networks, promoting a seamless cross chain experience.
