7.3. Will these standards work with other blockchains?

• The ERC standards, such as ERC20, ERC721, and ERC1155, are primarily designed for the Ethereum blockchain. Compatibility with other blockchains depends on whether those blockchains support the Ethereum Virtual Machine (EVM). Blockchains that are EVM-compatible, like Binance Smart Chain, Polygon, and Avalanche, can implement these standards with minimal adjustments. However, non-EVM blockchains, such as Bitcoin or Solana, require different protocols and standards, making direct compatibility challenging. Cross-chain solutions and bridges are being developed to facilitate interaction between different blockchain ecosystems. Projects like Polkadot and Cosmos aim to create interoperability between various blockchains, potentially allowing ERC standards to function across multiple platforms. Developers may need to create custom implementations or wrappers to adapt ERC standards for non-EVM blockchains.
