Glued Tools is a complete development toolkit for building smart contracts that interact with Glue Protocol. Whether you're creating a router, aggregator, yield strategy, lending protocol, or any DeFi application that works with glued assets, Glued Tools provides all the helper functions you need without requiring deep knowledge of Glue's internals.

Choose your version:

• GluedTools - Full support for ERC20 + ERC721 + batch operations
• GluedToolsERC20 - ERC20-only support with smaller bytecode (ideal for gas-sensitive apps)

How to implement Glued Tools

Import to your project the Glue Expansions Pack

To implement the Expansions Pack you can go on Github or easily install via npm

npm install @glue-finance/expansions-pack

After importing Expansions Pack to your project, choose which version to import based on your needs:

// OPTION 1: Full ERC20 + ERC721 support
import {GluedTools} from "@glue-finance/expansions-pack/base/GluedTools.sol";

contract MyRouter is GluedTools {
    // Your code here - you now have access to all helper functions
}

// OPTION 2: ERC20-only (smaller bytecode, lower deployment cost)
import {GluedToolsERC20} from "@glue-finance/expansions-pack/base/GluedToolsERC20.sol";

contract MyYieldStrategy is GluedToolsERC20 {
    // Your code here - optimized for fungible tokens only
}

🎉 Congratulations! You've successfully implemented Glued Tools! Here are all the advantages you now have access to:

🆚 GluedTools vs GluedToolsERC20

Use GluedTools when:

• You need NFT support
• You're building a general-purpose protocol
• You work with both ERC20 and ERC721 assets

Use GluedToolsERC20 when:

• You only work with ERC20 tokens and ETH
• You want lower deployment gas costs
• You prefer a simpler API without fungible flags
