For Builders
How do I start building on Fractal?
Visit docs.fractalbitcoin.io to access developer guides, tutorials, and API references. You can launch CAT20 tokens, build with OP_CAT, and integrate BRC-20 and Runes natively.
What are CAT20 tokens?
CAT20 is a Fractal-native token standard that supports expressive, Bitcoin-compatible smart contracts using OP_CAT. It allows programmable logic, dynamic asset issuance, and secure user flows — all within Bitcoin’s UTXO model.
Can I port my dApp from Ethereum or Solana?
Fractal doesn’t run EVM code, but many application patterns — such as swaps, vaults, or staking — can be replicated using OP_CAT and covenant logic. Fractal is more expressive than Ethereum in some dimensions and more minimal by design.
What kind of apps can I build on Fractal?
Builders have launched:
Decentralized exchanges (PizzaSwap)
Runes & Ordinals marketplaces
zk-based verifiers and atomic swaps
Infrastructure for OP_CAT scripting
On-chain games and virtual economies
