The caller must specify a chain ID and some chain metadata. Now I am trying switch between two networks, I am using handleChainChanged, also I am passing chainId and Networkversion but, it is giving me error. through a malicious RPC endpoint), but that must be up to the App dev, if they are willing to expose their users to it and how they intend to mitigate it. Have a question about this project? @wighawag, I apologize for my tardy response. Cartoon series about a world-saving agent, who is an Indiana Jones and James Bond mixture.
amazon web services - Packer credentials issue error Wallets can used community-sourced lists like chainId.network to detect discrepancies, but other than that, it is ultimately the user's responsibility to do their due diligence. In general relativity, why is Earth able to accelerate? See my comment above : #3086 (comment). Hi @rekmarks, @pedrouid I stumbled over this EIP and would like to suggest some additions to this RPC method proposal. I think it is important to consider the UX consequences when writing EIP like this one and saying we can have improvements later, while we could already foresee the issues, is to me a bad idea. That said, community resources exist that can be leveraged to verify requests for many Ethereum chains. let say a button that then trigger "wallet_addEthereumChain". Keep in mind, any wallet can choose to implement both wallet_addEthereumChain and wallet_updateEthereumChain if they want. Connect and share knowledge within a single location that is structured and easy to search. Therefore, it would be good to see something like wssUrl as another option in the spec. In some ways, this EIP (EIP-3085) is about a resource and not about a specific rpc call. Why do I get different sorting for the same query on the same data in two identical MariaDB instances? I don't think there's anything in EIP-3085 preventing a wallet from implementing the method in this way, and I'll add it to security considerations. Connect and share knowledge within a single location that is structured and easy to search. So UX is actually very much improved. If the wallet does not have a concept of an active chain, the wallet MUST reject the request. Also we could use that interface to get updated information, avoiding manual code intervention.". We obviously cannot prevent the possibility of a unexpected error, but my point is that if we expect wallet to reject for different reason, the standard should aims to define these. If any issues arise with a particular RPC endpoint, the user can as you say manually remove it, and re-add a different one. In general relativity, why is Earth able to accelerate? I know how MetaMask is likely to handle those cases (we won't allow chain ID 0x1 to be added by request, for example), but your examples show why we need to avoid specifying how the wallet should handle the request. What are some ways to check if a molecular simulation is running properly? This function also allows the user to change the network they are connected to, for example, if I already have Binance Smart Chain connected to metamask, calling wallet_addEthereumChain changes the active network to BSC. What do you think of that? . However, I generally agree that they should be separate EIPs for the reasons @rekmarks mentioned. This way, the method call is only regarded as a success if the call itself caused the chain to be added to the wallet. Note that adding support for a chain is simply to have dictionary of chainId -> metadata (name, coin name, .) to ensure the wallet can display valid information to their users. ), and wallet_updateEthereumChain mentioned in EIP-2015, returns May not specify default MetaMask chain. The wallet should maintain a list of known chains, and verify requests to add chains against that list. So UX is actually very much improved. I need json schemas for this to add it. How strong is a strong tie splice to weight placed in it from above? HTTPS SHOULD always be used over HTTP. This is also mean that we can now remove some of the MAY and SHOULD. The wallet MAY reject the request for any reason. They are not incompatible but we could imagine a version of EIP-2015 that make EIP-3085 irrelevant: the network is added automatically (and temporarly) upon request. This past week Metamask introduced a new function called "wallet_addEthereumChain" which allows the user to automatically add a new Etheruem RPC to their wallet when prompted. While in some case it might be a good rule, I see it as a heuristic not as a hard rule. I am using wallet_addEthereumChain RPC function to add the custom network in metamask android app through our Dapp but it is showing an error wrong chainid. 1 Im trying to programmatically switch the metamask network of the user. On the other side, it could also increases the security risk (e.g. This makes it difficult to build a consistent UX around this feature for multi platform apps. As for iconUrl, a single SVG should always suffice, and as a wallet developer, I would probably ignore everything but the first valid URL in the array anyway. Regarding the separation of the 2 RPC in 2 different EIPs. What maths knowledge is required for a lab-based (molecular and cell biology) PhD? What is the procedure to develop a new force field for molecular simulation? Being separate EIPs just means that each wallet gets to make that decision separately. To me, this is enough to extract out that EIP, which leaves wallet_addEthereumChain and wallet_updateEthereumChain. The security issue I mention are about the metadata. Edit: More than anything, I feel like the spec can remain agnostic on the matter, and people will do what makes the most sense, which is probably switching the network. Is there a legal reason that organizations often refuse to comment on an issue citing "ongoing litigation"? And rejecting for a "not found" reason would simply be a the detriment of the wallet.
How to fix "NoCredentialProviders: no valid providers in chain Open your wallet go to tools >> wallet repair and click on Rescan blockchain files. If I add manually the network on metamask, using the same information it works. Also we could use that interface to get updated information, avoiding manual code intervention. There's then a question of what we do with the other URL fields, and iconUrl if we add it. then forgot about it and visit another app not realising it is being displayed wrong information. @tze42, I like your suggestion of supporting WebSockets, and multiple RPC URLs. Ascertaining the trustworthiness of actors in a decentralized system belongs to a related but ultimately distinct problem space from accessing such a system. I strongly believe that having a standard allowing unsafe metadata to be displayed is a really bad idea. Otherwise applications will have to consider the case where wallets do not implement wallet_hasEthereumChain and the issue it poses for the user experience. Sign in Asking for help, clarification, or responding to other answers. Why not explicitly define which parameter are optional and which one are mandatory Third, regarding errors and error codes, the specification states that the wallet must return an error if the request fails. Especially when such data is shared across apps. Letting the app decide the currency and name, etc is not a good idea. For security reasons, a wallet should always attempt to validate the chain metadata provided by the requester, and may choose to fetch the metadata elsewhere entirely. Putting in another way, Core is more than a wallet.
Ethereum(EVM) | BitKeep Docs This would already be better than letting malicious app doing it for you. Is it possible to send transaction in Polygon-mumbai using web3 and ethereumjs-tx? Can I trust my bikes frame after I was hit by a car if there's no visible cracking? e.g., a way to ask window.ethereum.request('provider_getCapabilities') and get back a list of all supported capabilities (e.g., EIPs) or something like ('provider_checkMethodAvailability', ['wallet_updateEthereumChain', 'wallet_hasEthereumChain', 'eth_sendTransaction']). Is it possible for rockets to exist in a world that is only in the early stages of developing jet aircraft? This PR should automatically merge in a moment: #3227. 3326, March 2021. Your experience seems to indicate it and I do not have any evidence of a better mechanism working. Also, in my experience, the EIP editors prefer smaller specs, and shipping two separate EIPs increases the likelihood of finalizing both specifications sooner. I agree with @wighawag that wallet_hasEthereumChain should probably be a dependency of wallet_addEthereumChain and wallet_updateEthereumChain since to use either of the latter two in a reasonable environment requires the former (otherwise you have to use exception handling for code flow, which is bad). All URL strings MUST include the protocol component of the URL. In July 2022, did China have more nuclear weapons than Domino's Pizza locations? Such a method would enable UX improvements, but is by no means required in order to grant dapps the ability to ask the user to add a network to their wallet. Is there a legal reason that organizations often refuse to comment on an issue citing "ongoing litigation"? Find centralized, trusted content and collaborate around the technologies you use most. rev2023.6.2.43474. It is easier to enforce implementation even for wallet that keep chain info only for a session, than letting any wallet to not implement it. What one-octave set of notes is most comfortable for an SATB choir to sing in unison/octaves? A malicious or faulty endpoint could return arbitrary chain IDs, and potentially cause the user to sign transactions for unintended chains. rev2023.6.2.43474. Thanks @MicahZoltu for sharing your opinion. I would remove those properties from the builder and as long as the AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY environment variables are exported the builder should pick them up. It's just a question of where the specification will live. It only takes a minute to sign up. If you too agree that this will lead to a better UX, why not make "wallet_hasEthereumChain" EIP a dependency to "wallet_addEthereumChain" or simply add it to the proposal.
