+# Secure Payment Confirmation (SPC) Wallets As A Service 👛 
+
+What if you could create a wallet instantly on any dapp, fund it & re-use it anywhere. 👀
+
+SPC wallets are built ontop of [Secure Payment Confirmation](https://w3c.github.io/secure-payment-confirmation/) a web api designed to streamline
+web2 payments that leverages passkeys to authenticate the user.
+
+We leverage the webauthn-side of the SPC protocol to create passkey wallets that are capable of securely signing transactions on any dapp.
+
+## What is this repo?
+
+This repo is a simple end-to-end implementation of SPC wallets, complete with [passkey wallet contracts](https://github.com/peterferguson/spc-hack/tree/main/packages/contracts), [a simple dapp frontend](https://github.com/peterferguson/spc-hack/tree/main/apps/dapp), [wallet application](https://github.com/peterferguson/spc-hack/tree/main/apps/wallet)
+& [a library](https://github.com/peterferguson/spc-hack/tree/main/packages/spc-lib) that lets you embed these wallets in your dapp.
+
+
+## 🖼️ Demo
+
+Below is a demo journey of a user that has never used the [wallet provider](https://spc-wallet.vercel.app) or the [dapp frontend](https://spc-dapp.web.app) before.

+
+### User Steps
+
+1. User clicks to claim but has no account -> dapp shows wallet creation popup
+2. User inputs a (globally unique to the wallet provider) username
+3. Counterfactual account is created linked to the public key of the passkey
+4. User again clicks to claim & is presented with an SPC confirmation modal
+5. User signs passkey, confirming that they have agreed to the transaction
+
+### Corresponding Technical Steps
+
+1. dapp check for stored credentials, fails to find any & falls back to showing wallet creation popup
+2. dapp & wallet provider communicate to ensure the username is available & create a passkey if so
+3. wallet provider stores the users credentials so they can be relayed to other dapps upon request
+4. dapp has prepared a `UserOp` representing the `Claim Coupon` NFT, creates a [`Payment Request`](https://w3c.github.io/payment-request/#paymentrequest-interface) to be signed by the passkey on confirmation of the SPC modal
+5. dapp (or wallet) send the signed `UserOp` to a bundler for inclusion.

+# Secure Confirmation Payment Library
+
+This library lets dapps create & operate a passkey wallet from any provider.
+What is even better is the user never has to leave the dapps site!
+
+All transactions are confirmed on the dapps webpage using the wallets passkey credentials.
