海外TECH	DEV Community	Web3 onboarding is terrible. How to make it better with Account Abstraction and Flow.	https://dev.to/mbogan/web3-onboarding-is-terrible-how-to-make-it-better-with-account-abstraction-and-flow-184d	Web onboarding is terrible How to make it better with Account Abstraction and Flow If you re a developer working on a web app you know that onboarding mainstream users into web is difficult Even with the promise of truly owning your data making near free worldwide payments and using a censorship free system the current process of creating and using a digital wallet is just too hard Fortunately there s a better way Account abstraction promises to streamline the process making user onboarding seamless and simple Flowーa decentralized public layer one blockchain designed for building web experiences for mainstream usersーhas used account abstraction to combine a hybrid custody model with walletless onboarding to create an onboarding that is easy simple and as straightforward as traditional apps Let s dive into the details to see how Hybrid Custody and Walletless Onboarding work together the architecture the code and what we can expect moving forward Why web onboarding is so difficultDigital wallets bring all the benefits of web including the assurance that no one can control your assets There are no middlemen such as banks taking a percentage of your money or third parties dictating what you can do However because most wallets are “self custody meaning only you have access youーand only youーare in charge of your keys There is no customer support if you make a mistake This means you must store your keys safely Don t store them in clear text on your computer where they can be hacked And don t write them down where someone can read them And don t lose them because there is no reset password in web so you ll lose everything You can see the issues In addition to the challenges of self custody you also need to understand tokens and payments How do you pay for your transactions What tokens do you need How do you move from fiat to tokens How do you transfer the tokens once you have them Oh you made a typo when you sent your tokens Sorry they re lost forever Again you can see how difficult this all is With all these obstacles it s easy to see why many people don t make it past step one of signing up for your app Custodial wallets great UX lacking ownershipDevelopers tried to solve this issue with custodial wallets These wallets manage the keys for you and have many benefits Signing up is easy You can use an email and password as you would for a traditional service and the wallet provider takes care of the rest If you lose your login credentials your keys are still accessible on the provider s servers you can simply request a password reset Since the wallet software runs on their servers providers can even pay your transaction fees You don t have to understand tokens funding and transfers But as the saying in web goes “Not your keys not your coins While custodial wallets solved many onboarding issues the wallet providers in the end owned the keys We re right back to the problems we wanted to get away from a centralized entity that can prevent you from using your tokens can close your account at a whim or can shut down completely taking your funds with them Wouldn t it be nice if you could have the best of both worlds Account abstraction to the rescue Account abstraction solves one of the fundamental issues of blockchain networks the distinction between externally owned accounts and contract accounts An externally owned account EOA is an account controlled by the user with a private key These are the traditional web wallets that we talked about above An EOA has a public address and initiates transactions such as sending tokens with the blockchain A contract account which is also just a smart contract is a program deployed on chain and executed by the network nodes Contract accounts don t initiate transactions Instead they respond to a transaction with an action of their own They have no private keyーthey are controlled by their code This type of account could be said to have app custody Account abstraction combines app custody and self custody into a new user experience UX giving users the benefits of both control of their wallets while abstracting away the wallet and blockchain altogether On Flow account abstraction is the basis for Walletless Onboarding using Hybrid Custody Hybrid Custody gives you the best of both worldsWalletless Onboarding allows developers to create an onboarding experience for users that is nearly seamless The walletless user journey from flow com The hybrid custody model uses account abstraction to allow account delegationーwhere a child account delegates control to a parent account through a Capability essentially allowing one account to control another Now the self custody account can be a parent account giving permissions to the app account which is now a child account With this setup the accounts work together and your app can work like this Your app creates the wallets for the users There is no barrier to entry hereーno key management no signing transactions no understanding of blockchain Users can use your app and buy and sell assets without knowing or caring about the technical details Your app can even subsidize transaction fees or let them fund their account with fiat such as USD And it all happens invisibly to the user Once the user comes back with their own wallet managed account your app can delegate access to the user s account Once linked the user has hybrid custody their wallet manages their main now “parent account which secondarily maintains access on the app created now “child account Since their main account now has access on the app created account they can bring app assets anywhere their wallet managed account goes They can trade your app s assets on marketplaces or share them with friends Yet at the same time since the app also has access to the account it can still facilitate seamless UX that acts on their behalf With this hybrid custody model users get to experience your app right away with minimal barriers and no risk And later on if they choose they can take control of the self custody account themselves enjoying all the real ownership and self sovereignty it brings Technical details of hybrid custody and account abstractionAccount CreationHow does all this work On Ethereum and many other blockchain networks an EOA is created from a public key The key is hashed and the first bits of this hash become the address of the account controlled by that key This makes account creation independent from the network but irrevocably ties an account to that key Flow uses a particular on chain function to create account addresses You can then add any number of keys to a Flow account adding and removing access based on the custodian of each key This means a transaction is required to create a new addressーso you can t create accounts offlineーbut it also makes Flow account ownership much more flexible You can see a full account creation example on GitHub but let s check out the crucial parts here userPrivateKey examples RandomPrivateKey userPublicKey flow NewAccountKey FromPrivateKey userPrivateKey SetHashAlgo crypto SHA SetWeight flow AccountKeyWeightThreshold serviceAccountAddress serviceAccountKey serviceSigner examples ServiceAccount flowClient createAccountTx templates CreateAccount flow AccountKey userPublicKey nil serviceAccountAddress createAccountTx SetProposalKey serviceAccountAddress serviceAccountKey Index serviceAccountKey SequenceNumber createAccountTx SetReferenceBlockID examples GetReferenceBlockId flowClient createAccountTx SetPayer serviceAccountAddress createAccountTx SignEnvelope serviceAccountAddress serviceAccountKey Index serviceSigner flowClient SendTransaction ctx createAccountTx First the user creates a key pair Pretty basic stuff Because on Flow you create accounts by sending an account creation transaction we need an existing account to send this transaction This housekeeping is the job of the ServiceAccount The createAccountTx receives the user s public key to control the new account later but the ServiceAccount which signs and pays for the transaction handles the rest In the case of your app you would own this service account so you could sign account creation transactions on behalf of your user also funding the account s creation Hybrid CustodyLet s get back to the hybrid custody model Your app can create app accounts for your users and link them to a public key that your app controls The app can then handle your user s transactions and assets and even sponsor their transaction fees just like any custodial account would do Later when a user decides to dive deeper into the web ecosystem and get their own wallet you can create and save a link to the app custodied account s AuthAccount Capability and delegate control to the user s wallet managed account You can see an example of this in the walletless arcade example where a multisig transaction is executed by the app to link a user s account to a walletless onboarding dapp custodied account to the signing user s wallet managed account SummaryIt s worth driving the point home that delegating access on the app created account is done via a linked Capability on the account which is then provided to the user This mechanism for account delegation is completely new to blockchain accounts and is only possible because of the account abstraction that s been native to Flow for years now This language API account linking feature is a huge advantage to accounts on Flow in addition to many other features m of n multisig re keying accounts etc which are only now beginning to be realized on other chains with their nascent non native account abstraction implementations Account abstraction is a powerful feature On Flow it enables a hybrid custody model that allows users to enjoy the benefits of a custodial account when they sign up while enabling them to take the account into self custody at any time It s a new and vastly improved user experience that hopefully brings millions more users into web	2023-04-19 12:51:24

海外TECH	DEV Community	The Serverless Toolbox - Tools To Build Serverless Apps Easier	https://dev.to/aws-heroes/the-serverless-toolbox-tools-to-build-serverless-apps-easier-1g5j	The Serverless Toolbox Tools To Build Serverless Apps EasierI recently wrote about some of the benefits of building a bunch of side projects I talked about building automations to take over mundane everyday tasks but one of the main points I mentioned was nagging at me a bit In the post I spoke about building a serverless toolbox as a result of all your side projects After you build a couple things you start to identify the functions you rewrite over and over You identify those patterns and put them together in a serverless toolbox to have at your disposal Truth time I did not practice what I preached In fact I got pretty lazy and started implementing some anti patterns Like tightly coupling my projects together by calling resources from one stack in another one directly by the ARN I m not proud of this as I like to lead by example so I decided to make a change I m happy to release the first version of my serverless toolbox a GitHub repo that deploys a set of functional tools that you can integrate into your applications with loose coupling mechanisms Let s cover some of the available functions What s in the toolbox For its initial release I have included four utility functions you can incorporate into your projects or AWS accounts All functions are written in Nodejs x Ask ChatGPT FunctionIf you needed a conversational Lambda function that will hold context of your ChatGPT conversations across invocations and execution environments I have you covered This function uses Momento Cache to temporarily store your conversation history with ChatGPT and communicates via the OpenAI API Give it a conversation key and a prompt and it will remember the question and answer the next time you provide the same conversation key Need to start a new conversation Give it a new conversation key UsageIf you want to use the function in your project in a state machine or put it behind API gateway you can resolve the ARN for it via SSM Here is an example of how you would consume it in SAM MyFirstStateMachine Type AWS Serverless StateMachine Properties Type STANDARD DefinitionUri workflows my definition asl json DefinitionSubstitutions AskChatGPTFunctionArn resolve ssm serverless toolbox ask chatgpt Policies Version Statement Effect Allow Action lambda InvokeFunction Resource resolve ssm serverless toolbox ask chatgpt See It In ActionIf you want to see an implementation of this function you can see it in my serverless ai fitness project It is used in a Step Function workflow to build a workout with the equipment I have available in my home gym It also creates a warmup and cooldown specifically for the generated workout Send API Request FunctionThis is a function I ve made probably times Almost every project I create integrates with some rd party API Sometimes they have SDKs other times only a REST endpoint is available This function is used to generically send API requests to a REST or other web API You provide it with auth details it will fetch your token out of Secrets Manager for you then it will hit the endpoint and return the response body as the payload Below is an example payload you can provide to the function secretKey key from auth token secret request method POST baseUrl headers x custom header value body title My title body markdown Hello auth prefix Bearer location header key Authorization query custom value anything you want The payload is completely composable so you can leave out anything that doesn t work for the endpoint you re calling If your request is public don t provide auth Don t have any query string parameters No problem don t supply the query object UsageSimilar to the Ask ChatGPT function this is intended to be used in a request response or synchronous manner As such the trigger needs to be manually created like including it in a Step Function workflow or behind an API Gateway endpoint When resolving this ARN you can use the SSM parameter serverless toolbox send api request See It In ActionThis Lambda function is implemented in my blog crossposting app It is called from a state machine to post articles to various publications In this project I created a Lambda function to generate payloads specifically for this function to use as simply as possible Send Email FunctionYes AWS makes it very easy to use SES Simple Email Service for sending emails That said I ve actually found it somewhat difficult to get my account turned on to production mode allowing me to send an email to any address I want So I tend to use SendGrid for sending emails This function uses SendGrid to asynchronously send an email in either plaintext or html format You just need to supply your SendGrid API key UsageSince emails are asynchronous by nature this function is triggered by an EventBridge event You publish an event to the default event bus with who to send the email to the subject and the content and your email will be sent for you Below is an example event you can publish to EventBridge DetailType Send Email Source my app Detail subject Dear reader have you heard of the serverless toolbox to allenheltondev gmail com html lt h gt Hello lt h gt lt p gt You might not believe this but sending an email is really lt i gt this simple lt i gt lt p gt See It In ActionIf you want to see how easy it is to send an email by publishing an event I have an example in my serverless newsletter app In a Step Function worklow that reports how my weekly newsletter performed I gather some analytic details from the SendGrid API then publish an EventBridge event to send those details to me in a weekly how did I do email Set Log Retention FunctionDid you know when you create a new Lambda function the CloudWatch logs for it are set to retain forever Chances are you don t need those logs forever But unless you do something about it you ll be paying for them indefinitely So I created a function that runs on a daily timer to set the retention of all your Lambda logs to a configured value Personally I keep logs for days before getting rid of them but the choice is yours The function will load all Lambda log groups with a retention period that does not match the configured value It then sets the retention period to whatever you have configured Since this runs on a daily timer there s nothing for you to do This will happen automatically after it is deployed As you create Lambda functions this will pick the new log groups up automatically and set the retention period on them This isn t something you d implement in your applications but it is a good clean up administrative function to have in your AWS account If you create hundreds of functions and actually use them this will end up saving you quite a bit of money Try It YourselfThese are all open source for you to use Deploy the toolbox into your AWS account and start using them The stack is currently deployed via a SAM template To deploy into your account you can run the following two commands assuming you have the SAM CLI installed sam build parallelsam deploy guidedThe guided flag will walk you through a wizard to get stack details and deployment parameters from you If there are any parameters you don t wish to supply like SendGrid information you can omit them and the template will not deploy any functions that use them I hope you find these useful it was intended to make building with serverless easier faster and more intuitive than before I will be updating my open source projects to use the toolbox so you can deploy them easier and have additional references As I continue to build and find more overlap with utility functions I ll update the repo and make more tools available If you have any you wish to add please open up a pull request Happy coding	2023-04-19
