### Description

Transfer fungible tokens using the SIP-10 standard with post-conditions

### Use Cases

* Transferring fungible tokens between wallets
* Integrating token transfers in dApps
* Building DEX or swap functionality
* Implementing payment systems with custom tokens

### Key Concepts

* **Standard interface** - All SIP-10 tokens implement `transfer`, `get-balance`, etc.
* **Post-conditions** - Protect users by ensuring exact amounts are transferred
* **Memos** - Optional field for including transfer notes
* SIP-10 is the fungible token standard on Stacks, similar to ERC-20
