SIP-10s

What Are SIP-10 Tokens?

SIP-10 is the standard for fungible tokens on the Stacks blockchain — a Layer 1.5 solution bringing smart contracts and DeFi to Bitcoin. It defines how tokens behave in Clarity smart contracts, allowing easy integration with wallets, DAOs, and DeFi apps. Unlike BRC-20 or Runes, SIP-10 tokens are fully on-chain on Stacks and secured by Bitcoin finality via Proof of Transfer (PoX).

🔧 How SIP-10 Works

• Tokens are managed through Clarity smart contracts

• Core functions include transfer, get-balance, and get-total-supply

• All interactions (mint, burn, send) are done via contract calls

• Supports optional metadata: name, symbol, decimals

💡 Key Features

• Smart contract-based: Fully programmable logic

• Bitcoin-secured: Anchored to Bitcoin via PoX

• DeFi-ready: Compatible with Stacks-native dApps

• Flexible: Custom minting rules and access control

🧱 Origin of SIP-10 Tokens

A SIP-10 token is created when a developer deploys a Clarity contract using the SIP-10 interface. The contract defines:

• Token name & symbol (e.g., USDSTX)

• Supply logic and minting rules

• Decimal precision (e.g., 6 or 8)

• Optional admin roles

Once deployed, the token is usable across Stacks wallets and dApps like ALEX, Velar, and Arkadiko and can be bridged to Bitcoin DeFi in wrapped formats.
