PolkaBTC Alpha Testnet is Live

Nov 30, 2020 · 2 min read

We are excited to announce the launch of the PolkaBTC Alpha testnet. This marks a major milestone of the BTC-Parachain and brings us one step closer to making Polkadot interoperable.

The first testnet release allows users to issue and redeem their first PolkaBTC and connects Bitcoin’s testnet to the BTC-Parachain testnet.

Go to to mint your first trustless testnet Bitcoin on Polkadot.

We have prepared a detailed user guide for PolkaBTC here:

This includes instructions for wallets, testnet coins, as well as step-by-step guides for issuing and redeeming PolkaBTC. You will need a desktop browser to test.

The BTC-Parachain allows users to mint 1:1 Bitcoin-backed assets onto Polkadot, called PolkaBTC, and use these across a wide range of applications, including decentralized exchanges, stablecoins, and lending protocols. Under the hood, the BTC-Parachain implements XCLAIM, the only cross-chain framework that is financially trustless, permissionless, and censorship-resistant — and is backed by top-tier research (IEEE S&P’19). The BTC-Parachain is expected to launch in February/March 2021.

The BTC-Parachain is built by Interlay, a team of ex-Imperial College PhDs and blockchain engineers, funded by a Web3 Foundation grant.

Interlay envisions a future where blockchains can seamlessly connect and interact, regardless of design and purpose. Interlay is building cross-chain infrastructure and DeFi products, backed by top-tier research:

  • PolkaBTC, the official trustless Bitcoin-Polkadot bridge, in collaboration with Parity Technologies, funded by the Web3 Foundation.
  • XOpts, the first trustless and non-custodial platform for cross-chain, physically settled BTC options on Ethereum. XOpts requires no price oracles or wrapped assets, and also acts as the first truly decentralized BTC exchange.

Founded by Imperial College London PhDs, Interlay’s team of researchers and engineers brings together expertise in blockchain interoperability, security, crypto-economics.
