# Core Concepts

## The Value Propositions of Stablecoins

Stablecoins offer four key value propositions:

1. **Permissionless**: Anyone, anywhere can access stablecoins (and therefore digital dollars), without intermediaries and middlemen like banks.
2. **Programmable**: Each stablecoin is a smart contract, unlocking programmability for money. Developers can program conditions into how money moves with stablecoins.
3. **Cheap**: Money can move globally between wallets at an extremely low cost through stablecoins and blockchain technology.
4. **Fast**: Global money movement with stablecoins can be settled substantially faster than traditional, legacy payment rails.

## The Role of Stablecoins in Payments

With these value propositions, stablecoins offer four key use cases for payment applications:

1. **Save**: Stablecoins allow people and businesses from all over the world to access a reliable store of value.
2. **Spend**: Stablecoins can be spent with certain merchants as a new form of money.
3. **Send**: Stablecoins can be sent across borders, to any business or person, everywhere.
4. **Earn**: Stablecoins offer permissionless access to interest and yield-bearing opportunities.
