Bitcoin DeFi
We're Building the Banks of tomorrow on Bitcoin.
Bitcoin-Powered
Magic
Three integrated services powering the Universal BRC-20 ecosystem
Building the Future of Bitcoin DeFi
The Universal BRC-20 Extension provides a complete, trustless financial stack on Bitcoin Layer 1
Enabling swaps, yield farming, and wrapped assets without compromising on security or decentralization.
Trustless by Design
Cryptographic proofs replace trust. All operations are verifiable on-chain with deterministic state machines.
Layer 1 Native
No Layer 2 bridges or custodial solutions. Everything runs directly on Bitcoin using OP_RETURN and Taproot.
Universal Standard
Backward compatible with BRC-20. Any compliant indexer can process Universal BRC-20 operations.
Protocol Specifications
