FarSend

Multi-chain batch sender for ETH and ERC-20 tokens — built for Farcaster.

🚀 Live App: https://farsend.vercel.app/

Overview

FarSend is a web-based batch sender that enables users to send ETH and ERC-20 tokens to multiple addresses in a single transaction across multiple Ethereum networks. Built as a Farcaster Mini App, FarSend streamlines token distributions for airdrops, community rewards, DAO payouts, and bulk transfers on Ethereum Mainnet, Base, Optimism, and Arbitrum.

Key Features

✅ Batch Sending

  • Send ETH or ERC-20 tokens to multiple addresses in one transaction
  • Significantly reduce gas costs compared to individual transfers
  • Streamline airdrops and reward distributions

🔗 Wallet Integration

  • Connect with any Web3 wallet via Reown AppKit
  • Non-custodial — your keys never leave your wallet
  • Direct wallet-to-wallet transfers
  • Automatic network detection and switching to Base

📊 Smart Input & Validation

  • Manual Entry: Paste addresses and amounts line-by-line
  • CSV/JSON Upload: Import recipient lists from files
  • Live Preview: See parsed data before dispatching
  • Address Validation: Automatic Ethereum address checksumming
  • Balance Checks: Verify sufficient funds before sending

🎯 ERC-20 Token Support

  • Send any ERC-20 token on Base
  • Automatic token contract validation
  • Built-in approval workflow for token spending
  • Display token symbol and decimals

🌐 Farcaster Integration

  • Native Farcaster Mini App
  • Launch directly from Farcaster clients
  • Optimized for mobile and desktop experiences

🎨 User Experience

  • Progress Stepper: Visual workflow (Connect → Define → Dispatch)
  • Real-time Summaries: See recipient count and total amounts
  • Transaction Tracking: Direct links to BaseScan for all transactions
  • Success Celebrations: Confetti animations on successful batches
  • Export Functionality: Download recipient lists as CSV

How It Works

  1. Connect Wallet
    Connect your Web3 wallet and ensure you're on Base Mainnet (Chain ID 8453)

  2. Define Token & Recipients

    • Select ETH or enter an ERC-20 token contract address
    • Input recipients manually or upload a CSV/JSON file
    • Format: address, amount per line

  3. Review & Dispatch

    • Review the summary (recipient count, total amount, token details)
    • For ERC-20 tokens, approve spending if needed
    • Click "Dispatch Batch" to send the transaction
    • Confirm in your wallet and wait for on-chain confirmation

Technical Stack

  • Frontend: Vanilla HTML/CSS/JavaScript with Tailwind CSS
  • Web3 Library: Ethers.js v6
  • Wallet Connection: Reown AppKit (formerly WalletConnect)
  • Blockchain: Base (Ethereum L2) - Chain ID 8453
  • Smart Contract: Custom BaseBatchSender for gas-optimized batch transfers
  • Social Layer: Farcaster Mini App SDK
  • Deployment: Vercel

Smart Contract

FarSend uses a deployed batch sender contract on Base Mainnet:

Contract Address: 0x8878b70a01bdda92ab8ea48dd7893b64c69298c0

Functions:

  • disperseEther(address[] recipients, uint256[] amounts) - Batch send ETH
  • disperseToken(address token, address[] recipients, uint256[] amounts) - Batch send ERC-20 tokens

  • Client-side validation: All address and amount validation happens in the browser
  • Balance verification: Checks for sufficient ETH/token balance before dispatch
  • Approval workflow: Explicit token approval step for ERC-20 transfers
  • Gas estimation: Smart gas limit calculation with safety buffers
  • Transaction receipts: Full on-chain verification of all transactions

Development

Local Setup

  1. Clone the repository
git clone https://github.com/yourusername/farsend.git
cd farsend
  1. Serve locally (any static file server works)
# Using Python
python -m http.server 8000
# Using Node.js
npx serve
# Using PHP
php -S localhost:8000
  1. Open http://localhost:8000 in your browser

Configuration

The app automatically loads the Base contract configuration from base.json:

{
"address": "0x8878b70a01bdda92ab8ea48dd7893b64c69298c0",
"abi": [...]
}

Deployment

Deploy to Vercel:

vercel deploy

The app includes a vercel.json configuration for proper routing and redirects.

Manifest: /.well-known/farcaster.json
App URL: https://farsend.vercel.app
Splash Screen: Custom animated loading screen with brand identity

Gas Optimization

FarSend uses a custom batch sender contract that optimizes gas usage:

  • Single transaction: All transfers execute in one on-chain transaction
  • Efficient loops: Optimized Solidity loops for minimal gas overhead
  • No unnecessary storage: Contract uses minimal state storage
  • Direct transfers: ETH sent directly without intermediate steps

Typical gas savings: 40-60% compared to individual transfers for batches of 10+ recipients

Browser Compatibility

  • Chrome/Edge (v90+)
  • Firefox (v88+)
  • Safari (v14+)
  • Brave (v1.24+)

FarSend
Multi-chain batch sender for ETH and ERC-20 tokens — built for Farcaster.
🚀 Live App: https://farsend.vercel.app/
Overview
FarSend is a web-based batch sender that enables users to send ETH and ERC-20 tokens to multiple addresses in a single transaction across multiple Ethereum networks. Built as a Farcaster Mini App, FarSend streamlines token distributions for airdrops, community rewards, DAO payouts, and bulk transfers on Ethereum Mainnet, Base, Optimism, and Arbitrum.
Key Features
✅ Batch Sending
  • Send ETH or ERC-20 tokens to multiple addresses in one transaction
  • Significantly reduce gas costs compared to individual transfers
  • Streamline airdrops and reward distributions
🔗 Wallet Integration
  • Connect with any Web3 wallet via Reown AppKit
  • Non-custodial — your keys never leave your wallet
  • Direct wallet-to-wallet transfers
  • Automatic network detection and switching to Base
📊 Smart Input & Validation
  • Manual Entry: Paste addresses and amounts line-by-line
  • CSV/JSON Upload: Import recipient lists from files
  • Live Preview: See parsed data before dispatching
  • Address Validation: Automatic Ethereum address checksumming
  • Balance Checks: Verify sufficient funds before sending
🎯 ERC-20 Token Support
  • Send any ERC-20 token on Base
  • Automatic token contract validation
  • Built-in approval workflow for token spending
  • Display token symbol and decimals
🌐 Farcaster Integration
  • Native Farcaster Mini App
  • Launch directly from Farcaster clients
  • Optimized for mobile and desktop experiences
🎨 User Experience
  • Progress Stepper: Visual workflow (Connect → Define → Dispatch)
  • Real-time Summaries: See recipient count and total amounts
  • Transaction Tracking: Direct links to BaseScan for all transactions
  • Success Celebrations: Confetti animations on successful batches
  • Export Functionality: Download recipient lists as CSV
How It Works
  1. Connect Wallet
    
Connect your Web3 wallet and ensure you're on Base Mainnet (Chain ID 8453)
  2. Define Token & Recipients
    • Select ETH or enter an ERC-20 token contract address
    • Input recipients manually or upload a CSV/JSON file
    • Format: address, amount per line
  3. Review & Dispatch
    • Review the summary (recipient count, total amount, token details)
    • For ERC-20 tokens, approve spending if needed
    • Click "Dispatch Batch" to send the transaction
    • Confirm in your wallet and wait for on-chain confirmation
Technical Stack
  • Frontend: Vanilla HTML/CSS/JavaScript with Tailwind CSS
  • Web3 Library: Ethers.js v6
  • Wallet Connection: Reown AppKit (formerly WalletConnect)
  • Blockchain: Base (Ethereum L2) - Chain ID 8453
  • Smart Contract: Custom BaseBatchSender for gas-optimized batch transfers
  • Social Layer: Farcaster Mini App SDK
  • Deployment: Vercel
Smart Contract
FarSend uses a deployed batch sender contract on Base Mainnet:
Contract Address: 0x8878b70a01bdda92ab8ea48dd7893b64c69298c0
Functions:
  • disperseEther(address[] recipients, uint256[] amounts) - Batch send ETH

FarSend
Multi-chain batch sender for ETH and ERC-20 tokens — built for Farcaster.
🚀 Live App: https://farsend.vercel.app/
Overview
FarSend is a web-based batch sender that enables users to send ETH and ERC-20 tokens to multiple addresses in a single transaction across multiple Ethereum networks. Built as a Farcaster Mini App, FarSend streamlines token distributions for airdrops, community rewards, DAO payouts, and bulk transfers on Ethereum Mainnet, Base, Optimism, and Arbitrum.
Key Features
✅ Batch Sending
  • Send ETH or ERC-20 tokens to multiple addresses in one transaction
  • Significantly reduce gas costs compared to individual transfers
  • Streamline airdrops and reward distributions
🔗 Wallet Integration
  • Connect with any Web3 wallet via Reown AppKit
  • Non-custodial — your keys never leave your wallet
  • Direct wallet-to-wallet transfers
  • Automatic network detection and switching to Base
📊 Smart Input & Validation
  • Manual Entry: Paste addresses and amounts line-by-line
  • CSV/JSON Upload: Import recipient lists from files
  • Live Preview: See parsed data before dispatching
  • Address Validation: Automatic Ethereum address checksumming
  • Balance Checks: Verify sufficient funds before sending
🎯 ERC-20 Token Support
  • Send any ERC-20 token on Base
  • Automatic token contract validation
  • Built-in approval workflow for token spending
  • Display token symbol and decimals
🌐 Farcaster Integration
  • Native Farcaster Mini App
  • Launch directly from Farcaster clients
  • Optimized for mobile and desktop experiences
🎨 User Experience
  • Progress Stepper: Visual workflow (Connect → Define → Dispatch)
  • Real-time Summaries: See recipient count and total amounts
  • Transaction Tracking: Direct links to BaseScan for all transactions
  • Success Celebrations: Confetti animations on successful batches
  • Export Functionality: Download recipient lists as CSV
How It Works
  1. Connect Wallet
    
Connect your Web3 wallet and ensure you're on Base Mainnet (Chain ID 8453)
  2. Define Token & Recipients
    • Select ETH or enter an ERC-20 token contract address
    • Input recipients manually or upload a CSV/JSON file
    • Format: address, amount per line
  3. Review & Dispatch
    • Review the summary (recipient count, total amount, token details)
    • For ERC-20 tokens, approve spending if needed
    • Click "Dispatch Batch" to send the transaction
    • Confirm in your wallet and wait for on-chain confirmation
Technical Stack
  • Frontend: Vanilla HTML/CSS/JavaScript with Tailwind CSS
  • Web3 Library: Ethers.js v6
  • Wallet Connection: Reown AppKit (formerly WalletConnect)
  • Blockchain: Base (Ethereum L2) - Chain ID 8453
  • Smart Contract: Custom BaseBatchSender for gas-optimized batch transfers
  • Social Layer: Farcaster Mini App SDK
  • Deployment: Vercel
Smart Contract
FarSend uses a deployed batch sender contract on Base Mainnet:
Contract Address: 0x8878b70a01bdda92ab8ea48dd7893b64c69298c0
Functions:
  • disperseEther(address[] recipients, uint256[] amounts) - Batch send ETH
  • disperseToken(address token, address[] recipients, uint256[] amounts) - Batch send ERC-20 tokens
