# Silvatree > A Capacity Exchange is a B2B network where UK SMEs sell spare capacity (unsold time, unfilled rooms, empty seats, surplus stock) for Silva instead of cash, then spend Silva on real business expenses. Silvatree is a Capacity Exchange designed as a modern, structurally safer evolution of traditional Trade Exchange models. Silvatree owns and operates the Capacity Exchange model in the UK. Silva is a unit of account (1 Silva = £1 for record-keeping), not money. Silvatree is not a bank and never lends. ## Key pages - [Silvatree homepage](https://silvatree.co/): what a Capacity Exchange is and how UK SMEs use it. - [About Silvatree](https://silvatree.co/about): who Silvatree is, what Silva is, and how the exchange stays safe. - [Silvatree FAQ](https://silvatree.co/faq): straight answers on the model, Silva, safety and fees, and getting started. - [Silvatree Blog](https://silvatree.co/blog): articles on the Capacity Exchange model, idle capacity and cashflow. - [Do You Have to Sign a Personal Guarantee to Trade Your Spare Capacity?](https://silvatree.co/blog/do-you-need-a-personal-guarantee-to-join): Why credit-line exchanges ask a director to guarantee the debt, what BBX's and Bartercard's rules say, and why a Capacity Exchange has nothing to guarantee. - [Who Are You Actually Contracting With When You Join a Trade Exchange?](https://silvatree.co/blog/who-are-you-contracting-with): Before fees or network size, find out which single entity holds your account, whose law governs the contract, and which forum decides a dispute. - [A 90-Day Plan for Putting Idle Capacity to Work](https://silvatree.co/blog/90-day-idle-capacity-plan): A staged, three-month plan for listing spare capacity carefully, watching what actually sells, and scaling only once real trades prove it works for your business. - [Be Everywhere Your Best Buyers Are](https://silvatree.co/blog/be-everywhere-your-best-buyers-are): A practical guide to showing up where buyers already gather, through honest video, borrowed audiences, consistent content and a simple community, without a bigger ad budget. - [Build a Resilient, Profitable Business Without Cutting Costs First](https://silvatree.co/blog/build-a-resilient-profitable-business): Protect your visibility, stack value instead of discounting, track profit not revenue, keep adapting, and fund it all with idle capacity you already own. - [The Reserve Sitting Next to Your Cash Reserve](https://silvatree.co/blog/capacity-as-a-cash-reserve): Your cash reserve protects wages and tax.
