+# zkFold Smart Wallet API
+
+This repository houses off-chain code and server endpoints to interact with zk based smart wallet by [zkFold](https://zkfold.io/).

+## Structure of repository
+
+- [`zkfold-smart-wallet-api`](./zkfold-smart-wallet-api/) provides off-chain code to interact with the wallet.
+- [`zkfold-smart-wallet-server-lib`](./zkfold-smart-wallet-server-lib/) serves endpoints using our off-chain code to easily interact with the wallet.

+## zkFold Smart Wallet API Server
+
+### Building locally from source using the Haskell Toolchain
+
+1. Make sure your environment is configured properly, consult ["How to build?"](https://atlas-app.io/getting-started/how-to-build) section of Atlas documentation for it.
+2. Prepare a configuration, which can be stored either in file or in `SERVER_CONFIG` environment variable. Structure of it is as follows:
+
+    ```yaml
+     # Blockchain provider used by Atlas, our off-chain transaction building tool.
+     # Head over to https://atlas-app.io/getting-started/endpoints#providing-data-provider section to know how to configure `coreProvider` and what all options are available for it.
+    coreProvider:
+      maestroToken: YOUR_MAESTRO_TOKEN
+      turboSubmit: false
+     # Network id, only `mainnet` and `preprod` are supported for at the moment.
+    networkId: mainnet
+     # Logging configuration. It's an array to cater for potentially multiple scribes.
+     # See it's description mentioned at https://atlas-app.io/getting-started/endpoints#providing-data-provider for more information.
+    logging:
+      - type:
+          tag: stderr
+         # Possible values of `severity` are `Debug`, `Info`, `Warning` and `Error`.
+        severity: Debug
+         # Possible values of `verbosity` are `V0`, `V1`, `V2`, `V3` and `V4`. Consult https://hackage.haskell.org/package/katip-0.8.8.0/docs/Katip.html#t:Verbosity for more information about it.
+        verbosity: V2
+     # Port to serve endpoints at.
+    port: 8082
+     # API key to protect server endpoints with. It's value must be provided under `api-key` header of request.
+    serverApiKey: YOUR_SECRET_KEY
+     # UTxO to be used as collateral.
+    collateral: tx-id#tx-ix
+     # Wallet that provides UTxO to be used as collateral.
+    collateralWallet:
+      tag: mnemonicWallet
+      contents:
+        mnemonic:
+          - health
+          - unable
+          - dog
+          - lend
+          - artefact
+          - arctic
+          - dinner
+          - energy
+          - silent
+          - wealth
+          - shock
+          - safe
+          - glad
+          - mail
+          - gas
+          - flag
+          - beauty
+          - penalty
+          - mixed
+          - garbage
+          - erupt
+          - wonder
+          - magnet
+          - around
+        # Account index.
+        accIx: 0
+        # Payment address index.
+        addrIx: 0
+    ```
+3. Run the server with command `cabal run zkfold-smart-wallet-server -- serve -c my-config.yaml`.
+
+   Call: `cabal run zkfold-smart-wallet-server -- -h` for help. 😉
+
+4. Test if server is running successfully by calling, say, `/settings` endpoint. Example `curl` request: `curl -H 'api-key: YOUR_SECRET_KEY' -X GET http://localhost:8082/v0/settings | jq`, assuming port was specified as `8082`. On success, it should return something akin to:
+
+```json
+{
+  "network":"mainnet",
+  "version":"0.1.0",
+  "collateral":"tx-id#tx-ix",
+  "collateral_address":"addr1qx...w60mw"
+}
+```
+
+### OpenApi documentation
+
+Endpoints made available by server are specified [here](./web/openapi/api.yaml).
