About

The problem it solves > #### Restaking Bitcoin > > - bitcoin staking is now possible via Babylon and others. > - no tooling yet to build restaking on bitcoin. > > *EigenBTC* solves this **problem!**. EigenBTC enables ethereum users to create BTC staking pools on babylon chain, using schnorr signatures on bitcoin and IBC. The staked rewards are sent to a MultisigThresholdPubkey on cosmos, but controlled via zetachain

How it's made

Challenges we ran into # Eigenlayer on Babylon The original goal was to build eigenlayer ontop of babylon chain. Babylon chain didnt launch a usable testnet until wednesday morning so the project got delayed until we could actually test the hypothesis. It was challenging to figure out how to create multiparty bitcoin signatures, then connect to babylons testnet and wire everything up. The main issue was due to the number of different libraries and chains involved: - bitcoin -> zeta - bitcoin -> evm - bitcoin -> IBC doing cross chain dapp development is still unbelievelbly compleicated! - evm to cosmos is hard - evm to bitcoin is hard - key generation and storage is hard - none of the bitcoin providers supported signet BTC on the last day of the hackathon **babylon shut down their testnet** so we were not able to demo our working prototype
