Create A Wallet

These steps outline a repeatable process for creating a new BENJI wallet. Franklin Templeton will create a wallet for you, so you will not need to come into this process with your own wallet.

Prerequisites​

  • $env:BENJI_ACCESS_TOKEN is already set
  • you know your networkId
  • you know your productId
  • you know your institutionEntityId

Step 1: Generate a wallet signing keypair​

This creates the Ed25519 keypair used for wallet intent signing. Save the private key somewhere secure after creation.

$keyPair = @'
import { generateKeyPairSync } from "crypto";

const { publicKey, privateKey } = generateKeyPairSync("ed25519");

process.stdout.write(JSON.stringify({
  pubKey: publicKey.export({ type: "spki", format: "der" }).toString("base64"),
  priKey: privateKey.export({ type: "pkcs8", format: "der" }).toString("base64")
}));
'@ | node --input-type=module - | ConvertFrom-Json

$pubKey = $keyPair.pubKey
$priKey = $keyPair.priKey

Step 2: Set your wallet inputs​

$networkId = "YOUR_NETWORK_ID"                   # Example: STR
$productId = "YOUR_PRODUCT_ID"
$institutionEntityId = "YOUR_INSTITUTION_ENTITY_ID"
$walletName = "YOUR_WALLET_NAME"
$signingKeyName = "InitialKey"

Step 3: Run walletCreate​

$body = @{
  query = @'
mutation (
  $networkId: String!,
  $productId: ID!,
  $walletName: String!,
  $institutionEntityId: ID!,
  $signingKeyName: String!,
  $signingKey: String!
) {
  walletCreate(
    institutionInput: {
      networkId: $networkId
      productId: $productId
      walletName: $walletName
      institutionEntityId: $institutionEntityId
      signingKey: {
        signingKeyScheme: SUMMARY_ED25519
        signingKeyName: $signingKeyName
        signingKey: $signingKey
      }
    }
  ) {
    walletId
    walletAddress
  }
}
'@
  variables = @{
    networkId = $networkId
    productId = $productId
    walletName = $walletName
    institutionEntityId = $institutionEntityId
    signingKeyName = $signingKeyName
    signingKey = $pubKey
  }
} | ConvertTo-Json -Depth 10

Invoke-RestMethod `
  -Uri "https://api-uat.frk.com/tf/platform/bve/graphql" `
  -Method POST `
  -Headers @{ Authorization = "Bearer $env:BENJI_ACCESS_TOKEN" } `
  -ContentType "application/json" `
  -Body $body | ConvertTo-Json -Depth 10

Save these outputs​

After the call succeeds, keep:

  • walletId
  • walletAddress
  • the generated $priKey

You will need the wallet signing private key later for transaction intent signing.
