This quickstart walks through the minimum OMS Wallet SDK flow: install an SDK, create or configure the client, authenticate with email OTP, and send a first transaction from the embedded wallet.
Swift and Kotlin are native app SDKs. TypeScript is best for web, Node, and JavaScript apps.
1. Get project credentials Go to the Polygon project dashboard , create an account, and set up a new project. Copy your project access key and project ID.
2. Install an SDK pnpm add @0xsequence/typescript-sdk@alpha viem
dependencies : [ . package ( url : "https://github.com/0xsequence/swift-sdk.git" , exact : "0.1.0-alpha.1" ) ] . target ( name : "YourApp" , dependencies : [ . product ( name : "OMS SDK" , package : "swift-sdk" ) ] )
dependencies { implementation ( "io.github.0xsequence:oms-client-kotlin-sdk:0.1.0-alpha.1" ) }
3. Create the client Create the client once when your app starts, then reuse it for wallet operations.
import { OMSClient } from '@0xsequence/typescript-sdk' const oms = new OMSClient ({ publicApiKey: 'YOUR_PROJECT_ACCESS_KEY' , projectId: 'YOUR_PROJECT_ID' , })
import OMS_SDK let oms = OMSClient ( projectAccessKey : "YOUR_PROJECT_ACCESS_KEY" , projectId : "YOUR_PROJECT_ID" )
import com.omsclient.kotlin_sdk.OMSClient val client = OMSClient ( context = context, publicApiKey = "YOUR_PROJECT_ACCESS_KEY" , projectId = "YOUR_PROJECT_ID" , )
4. Authenticate with email Email authentication is a two-step OTP flow. Start auth, show your OTP input, then complete auth with the user-entered code.
await oms . wallet . startEmailAuth ({ email: 'user@example.com' }) const { walletAddress } = await oms . wallet . completeEmailAuth ({ code: '123456' }) console . log ( 'Wallet address:' , walletAddress )
try await oms. wallet . startEmailAuth ( email : "user@example.com" ) let result = try await oms. wallet . completeEmailAuth ( code : "123456" ) if case let . walletSelected (walletAddress, _ , _ , _ ) = result { print ( "Wallet address:" , walletAddress) }
import com.omsclient.kotlin_sdk.wallet.CompleteAuthResult client.wallet. startEmailAuth ( "user@example.com" ) val result = client.wallet. completeEmailAuth ( "123456" ) check (result is CompleteAuthResult.WalletSelected) println ( "Wallet address: ${ result.walletAddress } " )
5. Send a first transaction Send a native token transaction on Polygon Amoy. Values are raw base-unit values. On supported testnets, fee options are automatically sponsored.
import { Networks } from '@0xsequence/typescript-sdk' import { parseEther , type Address } from 'viem' const recipient = '0xRecipient' as Address const tx = await oms . wallet . sendTransaction ({ network: Networks . amoy , to: recipient , value: parseEther ( '0' ), }) console . log ( 'Transaction:' , tx . txnHash ?? tx . txnId )
let tx = try await oms. wallet . sendTransaction ( network : . polygonAmoy , to : "0xRecipient" , value : "0" ) print ( "Transaction:" , tx. txnHash ?? tx. txnId )
import com.omsclient.kotlin_sdk.Network import java.math.BigInteger val tx = client.wallet. sendTransaction ( network = Network.AMOY, to = "0xRecipient" , value = BigInteger.ZERO, ) println ( "Transaction id: ${ tx.txnId } " ) println ( "Transaction hash: ${ tx.txnHash } " )
