Developers can build on tBTC. There are several resources to help devs use tBTC infrastructure to bring Bitcoin to Ethereum. Get started with the following resources:
- How to Integrate TBTC into Your Defi Dapp
- The Ropsten-connected tBTC dApp
- tBTC smart contracts
- The technical specification
- The Solidity API documentation
Developers are already building on tBTC using the tools above. The hackathon at ETHDenver produced several excellent applications that may provide examples.
