Implementation Summary: Issues #587-590

Overview

This document summarizes the implementation of four interconnected features for the StellarForge token deployment dApp:

  • #587: Freighter Wallet Connection
  • #588: Token Creation Form UI
  • #589: StellarService Token Deployment
  • #590: IPFS Metadata Upload via Pinata

All implementations follow the acceptance criteria and are production-ready.

#587: Freighter Wallet Connection ✅

Status: COMPLETE (Already Implemented)

The wallet service was already fully implemented in frontend/src/services/wallet.ts.

Key Features:

  • isInstalled(): Checks for Freighter browser extension using isConnected() API
  • connect(): Calls getAddress() from Freighter API to get user's public key
  • signTransaction(xdr, network): Signs transactions using Freighter's signTransaction with network passphrase
  • getBalance(address, network): Fetches XLM balance from Horizon API
  • Error Handling:
    • Extension not installed
    • User rejected connection
    • Network mismatch detection
    • Clear error messages for all scenarios

Integration Points:

  • WalletContext manages wallet state and connection lifecycle
  • useWallet() hook provides wallet state to components
  • Automatic balance refresh on network changes
  • Persistent connection checking on app load

Acceptance Criteria Met:

✅ Clicking Connect Wallet opens Freighter popup ✅ Connected address is displayed in UI (truncated via truncateAddress()) ✅ Disconnecting clears wallet state ✅ Appropriate error messages shown for all failure scenarios

#588: Token Creation Form UI ✅

Status: COMPLETE

New Component: TokenForm

Location: frontend/src/components/TokenForm.tsx

Features:

  • Real-time Validation:

    • Validates on blur and on submit
    • Uses validateTokenParams() from utils
    • Field-level error messages displayed inline

  • Form Fields:

    • Token Name (1-32 chars, alphanumeric + spaces/hyphens/underscores)
    • Token Symbol (1-12 chars, alphanumeric + hyphens)
    • Decimals (0-18)
    • Initial Supply (must be > 0)

  • UI Features:

    • Estimated fee display (0.01 XLM)
    • Network indicator (testnet/mainnet)
    • Submit button disabled until:
      • Form is valid
      • Wallet is connected
    • Loading state during deployment
    • Error messages for validation failures

Integration:

  • Used in CreateToken component
  • Integrates with useWalletContext() for connection state
  • Integrates with useNetwork() for network display
  • Integrates with useToast() for user feedback

Updated Component: CreateToken

Location: frontend/src/components/CreateToken.tsx

Changes:

  • Replaced placeholder with full token creation flow
  • Displays success message with token address after deployment
  • Includes ShareButton for deployed tokens
  • Handles deployment errors gracefully

i18n Updates

Added translation keys in frontend/src/i18n/en.json:

  • tokenForm.nameLabel, namePlaceholder
  • tokenForm.symbolLabel, symbolPlaceholder
  • tokenForm.decimalsLabel
  • tokenForm.initialSupplyLabel
  • tokenForm.estimatedFee, feeDescription
  • tokenForm.network
  • tokenForm.connectWalletFirst
  • tokenForm.walletNotConnected
  • tokenForm.validationFailed
  • tokenForm.submitError
  • tokenForm.deployedSuccessfully

Acceptance Criteria Met:

✅ All fields validate on blur and on submit ✅ Invalid inputs show descriptive error messages ✅ Submit button disabled when form invalid or wallet disconnected ✅ Fee estimate visible before submission

#589: StellarService Token Deployment ✅

Status: COMPLETE (Already Implemented + Enhanced)

The deployToken() method was already fully implemented in frontend/src/services/stellar.ts.

Implementation Details:

Method: StellarService.deployToken(params)

async deployToken(params: {
  name: string
  symbol: string
  decimals: number
  initialSupply: string
  salt: string
  tokenWasmHash: string
  feePayment: string
}): Promise<DeploymentResult>

Process:

  1. Validation: Checks factory contract ID and wallet connection
  2. Build Operation: Creates Operation.invokeContractFunction for create_token
  3. Simulate: Calls server.simulateTransaction() to get resource fees
  4. Assemble: Uses rpc.assembleTransaction() with simulated data
  5. Sign: Calls walletService.signTransaction() via Freighter
  6. Submit: Sends transaction via server.sendTransaction()
  7. Poll: Waits for confirmation with pollTransaction()
  8. Extract Result: Parses return value to get token address

Error Handling:

  • Simulation errors caught and parsed via parseContractError()
  • Insufficient fee errors surfaced with clear messages
  • Network errors handled gracefully
  • Transaction timeout after 30 attempts (60 seconds)

Configuration Updates:

  • Added VITE_TOKEN_WASM_HASH environment variable
  • Updated STELLAR_CONFIG to include tokenWasmHash
  • Updated .env.example with new variable documentation

Acceptance Criteria Met:

✅ Token successfully deployed on testnet end-to-end ✅ DeploymentResult with tokenAddress and transactionHash returned ✅ Contract errors surface as readable messages

#590: IPFS Metadata Upload via Pinata ✅

Status: COMPLETE (Already Implemented + New Component)

The IPFSService was already fully implemented in frontend/src/services/ipfs.ts.

Existing IPFSService Features:

  • uploadMetadata(image, description, tokenName, onProgress):

    • Validates image (JPEG/PNG/GIF, max 5MB)
    • Uploads image to Pinata via pinFileToIPFS
    • Builds metadata JSON with name, description, image URI
    • Uploads metadata JSON via pinJSONToIPFS
    • Returns ipfs://CID format URI
    • Progress callback (0-100%)

  • getMetadata(uri):

    • Fetches metadata from Pinata gateway
    • Parses JSON response
    • Validates IPFS URI format

  • Error Handling:

    • Config validation (API key/secret required)
    • File validation (type, size)
    • Authentication errors
    • Network errors with retry logic
    • Clear error messages

New Component: MetadataUploadForm

Location: frontend/src/components/MetadataUploadForm.tsx

Features:

  • Form Fields:

    • Token Name (required)
    • Description (optional)
    • Image File (JPEG/PNG/GIF, max 5MB)

  • Upload Progress:

    • Real-time progress bar (0-100%)
    • Percentage display
    • Disabled state during upload

  • Error Handling:

    • Validates image file before upload
    • Shows helpful error messages
    • Displays IPFS configuration warning if not set

  • Success Handling:

    • Calls onUploadComplete() callback with metadata URI
    • Resets form after successful upload
    • Shows success toast

Integration:

  • Can be used in token creation flow
  • Integrates with useToast() for feedback
  • Uses ipfsService for uploads
  • Checks isIpfsConfigured() before allowing uploads

Configuration:

  • VITE_IPFS_API_KEY: Pinata API key
  • VITE_IPFS_API_SECRET: Pinata API secret
  • IPFS_CONFIG in frontend/src/config/ipfs.ts

Acceptance Criteria Met:

✅ Image and metadata pinned on IPFS via Pinata ✅ Returned URI follows ipfs://CID format ✅ Upload progress/loading state communicated to caller ✅ Errors (invalid API key, file too large) thrown with clear messages
