This page lists the 6 published tools in the CoinSeek catalog for lending that support Arbitrum, most popular first.

Supported blockchains. Check that the tool runs on the network where your assets already are, since moving funds between chains adds steps and risk. Some tools support one chain, while others span several.
Collateral and borrowing options. Look at which assets can be deposited and borrowed, and whether the tool offers features like adjustable rates or loan management. Some focus on Bitcoin or ETH collateral, while others cover many assets.
Retail or institutional focus. Some tools are built for individuals, and others target institutions, fintechs or asset managers. Pick one whose design and onboarding match who you are.
Access: web, API or SDK. Most people use a web interface, but some tools are mainly APIs or SDKs meant for developers building their own products. Confirm how you can reach the tool before you start.
Costs and pricing details. Many catalog entries do not state pricing, so read the tool's own documentation for interest rates and any fees. Compare these before depositing or borrowing.
