+[ERC-3770](./eip-3770.md) introduces a new address standard to be adapted by wallets and dApps to display chain-specific addresses by using a human-readable prefix.
+
 ## Motivation
 
 The need for this proposal emerges from the increasing adoption of non-Ethereum Mainnet chains that use the Ethereum Virtual Machine (EVM). In this context, addresses become ambiguous, as the same address may refer to an EOA on chain X or a smart contract on chain Y. This will eventually lead to Ethereum users losing funds due to human error. For example, users sending funds to a smart contract wallet address which was not deployed on a particular chain.

-`address` is mandatory and MUST be a [ERC-55](./eip-55.md) compatible hexadecimal address
