# Notes for session C2 at WalletUncon 2023 Title of talk: Address and Payment Request Standards Convener(s) of talk: DC Posch, Nalin B Scribe(s) of talk: Links to any presentation matter: Tips: - if you use github or gitlab handles instead of names, that allows scribes and conveners to be easily findable/taggable in threads when these notes get published to the CASA github org) - preface remarks with name/handle and org if you WANT to be credited for contributions or ideas. - feel free to call multiple people "anon" if you don't catch their names or they do not give them - most scribes love an assist! ## Notes - Agenda and scoping - the main problem is that receiving funds can be ambiguous and complicated in a multichain world. - The aim of this discussion is to figuring out the options for unambiguously sending, we will especially focus on links as a tool for resolving these complexities - Sending funds can also be done via links - To fix the multichain ambiguouty, we have the EIP-3770 option which is to pre-pin the name of the chain, e.g. eth:0x... - This should be a discussion about the options around creating a standard - Round of questions - Why are testnet addresses and non-testnet addresses different? - no good answer - Why is no one using EIP-3770? - no non-obvious answer (little cross ecosystem movement) - Discussion - Users lose funds because they get the chains wrong - Keystore contracts have many disadvantages - URLS - URLs can be carry the information - Payments and Request links exists - web3 URI - using the web3:// URI would be one option, could be any URI (https://ethereum-magicians.org/t/standardize-url-format-for-web3-browsers/2422) - how do we be credibly neutral with domains? - eth.link or similar? - These URLs should resolve automatically - Users should have to be able to state preferred tokens and chains ## Links - [ERC 3770](https://eips.ethereum.org/EIPS/eip-3770) - [web3:// URI](https://ethereum-magicians.org/t/standardize-url-format-for-web3-browsers/2422) - Projects with claim links: [Daimo](https://daimo.com), [Peanut](https://peanut.to)
