Smart contract development CLI for GLIN Network

glin-forge is the official command-line tool for developing, deploying, and interacting with ink! smart contracts on the GLIN Network. Inspired by tools like GitHub CLI (gh) and Hardhat, it provides a seamless developer experience for blockchain development.

Features

• 🔨 Build & Test - Compile and test ink! smart contracts
• 🚀 Deploy - Deploy contracts to any network (testnet/mainnet/local)
• 📞 Interact - Call contract methods and query state
• 📝 TypeScript Generation - Auto-generate TypeScript types from ABI
• 🔍 Contract Verification - Verify contracts on block explorer
• ⚡ Gas Optimization - Built-in gas estimation and tips
• 🌐 Multi-network - Easy network switching (testnet, mainnet, local)

Installation

From Cargo (Recommended)

cargo install glin-forge

From Source

git clone https://github.com/glin-ai/glin-forge
cd glin-forge
cargo install --path .

Binary Downloads

Download pre-built binaries from GitHub Releases:

• Linux (x86_64, ARM64)
• macOS (Intel, Apple Silicon)
• Windows (x86_64)

Prerequisites

• Rust - Install from rustup.rs
• cargo-contract - Install with cargo install cargo-contract --force
• ink! - For writing smart contracts (optional)

Quick Start

1. Create a New Contract

# Create from ERC20 template
glin-forge new my-token --template erc20

cd my-token

2. Build the Contract

glin-forge build

3. Deploy to Testnet

glin-forge deploy \
  --network testnet \
  --account alice

4. Interact with Contract

# Query (read-only, no gas)
glin-forge query 5ContractAddr... balanceOf 5Account...

# Call (transaction, costs gas)
glin-forge call 5ContractAddr... transfer 5Recipient... 1000 \
  --account alice

5. Generate TypeScript Types

glin-forge typegen --output ./frontend/src/types

glin-forge new my-token --template erc20
cd my-token

# 2. Build contract
glin-forge build --release

# 3. Deploy to testnet
glin-forge deploy \
  --network testnet \
  --account alice \
  --args "1000000,MyToken,MTK" \
  --value 1

# 4. Query total supply
glin-forge query <CONTRACT_ADDR> totalSupply

# 5. Transfer tokens
glin-forge call <CONTRACT_ADDR> transfer <RECIPIENT> 100 \
  --account alice \
  --wait

# 6. Generate TypeScript types

Frontend Integration

After generating types:

import { useMyToken } from './contracts/useMyToken'
import { useContractTx } from '@glin-ai/sdk-react'

function TransferButton() {
  const { contract } = useMyToken('5ContractAddress...')
  const { execute, loading } = useContractTx({
    contract,
    method: 'transfer'
  })

  const handleTransfer = async () => {
    await execute('5Recipient...', 1000n)
  }

  return (
    <button onClick={handleTransfer} disabled={loading}>
      Transfer
    </button>
  )
}
