This is a mobile SDK providing access to the Tinyman AMM on the Algorand blockchain. It currently supports V1.1 Tinyman. This SDK is a wrapper for https://github.com/synycboom/tinyman-go-sdk (In case you are looking for Golang SDK).

You can download libraries for iOS and Android from releases page.

• For iOS, please see https://www.simpleswiftguide.com/how-to-add-xcframework-to-xcode-project/
• For Android, please see https://developer.android.com/studio/projects/android-library#psd-add-aar-jar-dependency

tinyman provides wrappers for tinyman-go-sdk and some wrapped algorand-go-sdk functions

See example for how to integrate this SDK with both iOS and Android.

Since this SDK is compiled from Go to mobile native libs, there are some limitations that this SDK cannot do.

• go-mobile has type restriction, so other unsupported types (from exported functions/parameters/returned values) are not able to be bundled to the libs.
• we have to create wrappers for the algorand-go-sdk such as the client, and other structs/functions and use them with this SDK, but it is not fully ported yet. because it requires a lot of effort to do.
• features that require algorand-go-sdk structs/functions like signing with kmd client kmd-client is not available right now.
• Some types used in tinyman-go-sdk like uint64, float64, or a slice of structs that are not []byte are not supported. We will use a string for uint64/float64 and an iterator for a slice and convert them inside the SDK.

Normally, the steps for calling the SDK are separated into 3 parts.

• call a prepareXXXX function to prepare transactions that you want
• sign transactions returned by the prepareXXXX function, will usually be signed by user account (other transactions will be signed by logic signature account inside the prepareXXXX function)
• submit transactions to the blockchain and wait for confirmation

• Bootstrapping
• Minting
• Burning
• Swapping
• Redeeming
• OptInApp
• OptInAsset

1. prepare bootstrap transactions

Android

// Fetch the asset1 token
val token = tinymanClient.fetchAsset(asset1Id)

// Fetch the ALGO token
val algo = tinymanClient.fetchAsset("0")

// Fetch the created pool
val pool = tinyman.Pool(
    algodClient,
    token,
    algo,
    null,
    tinymanClient.validatorAppID,
    account.address,
    true
)

// Prepare a transaction group for bootstrapping
// Note that some transactions need to be signed with LogicSig account, and they were signed in the function.
val txGroup = pool.prepareBootstrapTransactions(account.address)

iOS

var error: NSError?

// Fetch the asset1 token
let token = try tinymanClient.fetchAsset(asset1Id)

// Fetch the ALGO token
let algo = try tinymanClient.fetchAsset("0")

// Fetch the created pool
let pool = TinymanNewPool(
    algodClient,
    token,
    algo,
    nil,
    tinymanClient.getValidatorAppID(),
    account.getAddress(),
    true,
    &error
)!
if (error != nil) {
    throw error!
}

// Prepare a transaction group for bootstrapping
// Note that some transactions need to be signed with LogicSig account, and they were signed in the function.
let txGroup = try pool.prepareBootstrapTransactions(account.getAddress())

2. sign transactions

Android

txGroup.sign(account)

iOS

try txGroup.sign(account)

3. submit transactions

Android

val txId = tinymanClient.submit(txGroup, true)

iOS

let txId = tinymanClient.submit(txGroup, wait: true, error: &error)
if (error != nil) {
    throw error!
}

Open the example project with Android Studio or Xcode.

You can prepare environment for android development by running the following command. It will install an SDK and NDK in the current directory.

# in case you use linux
$ make development.linux

# in case you use mac
$ make development.osx

$ make init

You can run make build.ios or make build.android to build the SDK. It will automatically save the output to example directory.

You can run make release to build a release version of the SDK and zip all the files.

Nothing in the repo constitutes professional and/or financial advice. Use this SDK at your own risk.
