PolkaBTC is the trustless wrapped Bitcoin representation on Polkadot, imported via the Bitcoin bridge (BTC-Parachain) built by Interlay.
PolkaBTC is live on Rococo and Interlay will be launching a public Beta testnet to test the secure operation of the system, in particular Vaults and Relayers.
To achieve higher participation during Beta testnet, Interlay designed a campaign for incentivizing users to actively test critical components of the bridge by handing out rewards for specific actions / challenges - with feedback from the Polkadot outreach team.
Since the BTC-Parachain does not have a native token, Interlay would like to put forward a motion to fund the PolkaBTC Beta testnet incentives in DOT from the Polkadot Treasury.
The detailed proposal is presented here:
