rBTC Flyover

Flyover accelerates getting into Rootstock from Bitcoin by significantly reducing the wait times associated with the current PowPeg time. Developers, integrators or Liquidity Providers (LP) looking to provide rBTC access, Cross-chain swaps, and access to liquidity pools can integrate the Flyover SDK. Visit the LP integration section to get started.

Features of the Flyover

• Flyover significantly reduces the amount of time required to transfer BTC and RBTC between the Bitcoin and Rootstock networks
• Uses a trustless intermediaries, a pool of Liquidity providers
• Provides the same security guarantees as the Powpeg
• Customizable SDK for LPs and integrators

Who is it for?

For Liquidity Providers (LP) An LP provides liquidity in Rootstock (rBTC) and Bitcoin (BTC) on behalf of users in exchange for a fee (configurable) as a reward. The LP can be wallets, exchanges, aggregators or individuals and institutions. See section on LP Management for more information.

For Developers

The Flyover SDK is currently available on Mainnet and Testnet. To convert rBTC to BTC and vice versa, use the PowPeg App.

For General Users

Use the PowPeg App to Peg in and out of Rootstock, easily perform trust-minimized BTC and RBTC transfers between Bitcoin and Rootstock using Flyover. See section on Using the PowPeg App to learn about how you can convert BTC - rBTC and vice versa.

PowPeg vs rBTC Flyover

Here's a detailed comparison of the PowPeg vs rBTC Flyover.

	PowPeg	Flyover (Includes PowPeg)
Network (and Coin)	Bitcoin (BTC) and Rootstock (rBTC)	Bitcoin (BTC) and Rootstock (rBTC)
Key Differentiators	Native for Rootstock (as a Bitcoin sidechain)	Significantly Faster than the PowPeg
Core Concept	Federated 2 Way Peg	Liquidity Provider (LP) Service + Federated 2 Way Peg (i.e. the PowPeg)
Trust	Requires trust in PowPeg	Requires trust in PowPeg. LPs are trustless
Time to transfer value to Rootstock	100 Bitcoin Blocks (about 17 hours)	~20 minutes 1
Time for value transfer from Rootstock	4000 Rootstock Blocks (about 34 hours)	~15 minutes 2
Cost Structure	No service fees, Only blockchain TX fees on Bitcoin (for peg-in) and Rootstock (for peg-out)	LP provider fees (0.0001 rBTC) 3 + transaction fees on Rootstock + Bitcoin TX fee
Minimum Limit for value transfer	0.005 BTC for peg in and 0.004 rBTC for peg-out	Same as PowPeg for peg in (BTC). Peg out min (rBTC) is configurable by the LP (set at 0.004 rBTC initially)
Max Limit for value transfer	None	0.1 BTC and 0.1 rBTC 4

Notes

1. Based on the number of Bitcoin block confirmations configured by the LP (currently set at 2 Bitcoin block confirmations for amounts <= 0.1 BTC). Bitcoin blocks can take longer to confirm.
2. Based on the number of Rootstock block confirmations configured by the LP (currently set at 10 Rootstock confirmations for amounts <= 0.1 rBTC) + 1 Bitcoin block confirmation.
3. An LP can set their own fees. The initial LP In the PowPeg app has set its provider fee at 0.0001 rBTC so that the LP covers network fees when receiving and rebalancing funds from PowPeg.
4. There is no technical limit for transfers. It depends on the available liquidity and limitations set by the LP. The initial LP in the PowPeg app, has set the max transfer limits to 0.1 BTC/rBTC.

Use Cases

Here are some of the use cases provided by the Flyover:

For Developers

The Flyover offers a way for developers to integrate Flyover into wallets, dApps, DEXs and swaps using the Flyover SDK.

With Flyover:

• Wallet or exchange platforms can integrate Flyover to offer a seamless experience for depositing and withdrawing BTC and rBTC within their platform utilizing the liquidity provided by the Flyover LP network. This eliminates the long wait times associated with traditional peg-in methods, allowing users to quickly move funds between their wallets to other platforms.
• DeFi and Lending Platforms can integrate Flyover to allow users to easily deposit Bitcoin as collateral for borrowing assets on Rootstock. The faster peg-in times provided by Flyover would unlock borrowing opportunities for users who hold rBTC against other rootstock on-chain assets (MOC, USDRIF and others).

Flyover offers;

1. Streamlined and Customizable SDK Integration: The Flyover SDK provides developers with a user-friendly toolkit for integrating the Flyover functionalities into wallets, swaps, exchanges, and dApps, reducing development time and effort. The SDK can be configured to suit the user's needs.

2. Enhanced User Experience: By integrating Flyover, developers and integrators can offer their users a seamless experience for interacting with the Rootstock ecosystem, providing frictionless Bitcoin transfer options into Rootstock within their applications.

3. Increased security: Flyover is built on top of the proven security of the PowPeg.

For Liquidity Providers (LP)

An LP provides liquidity in Rootstock (rBTC) and Bitcoin (BTC) on behalf of users in exchange for a fee (configurable) as a reward. The LP can be wallets, exchanges, aggregators or individuals and institutions. See section on LP Management for more information.

With Flyover, the LP can:

• Contribute to the growth of the Rootstock Ecosystem by joining the Flyover's network of LPs to ensure there's sufficient liquidity for users to transfer Bitcoin (BTC) between the Bitcoin network and Rootstock (rBTC) for their user base while also serving as LPs providing services to other users.
• Assume both roles as an integrator and an LP, or may limit themselves as LPs by configuring the SDK accordingly.

Flyover Offers;

• Reduced friction in the peg-in/out processes: Flyover reduces the friction in the current Powpeg time. It solves the 100 blocks confirmation friction required in the native Powpeg. With Flyover, a minimum of 1-2 bitcoin block confirmation is needed instead (~20 minutes). Note that LPs can configure the number of blocks.

• Revenue potential: Flyover allows LPs to configure and earn revenue from users using their liquidity for BTC and rBTC transfers on the Flyover protocol.

• Increased User Reach: By being a part of the Flyover network of LPs, LPs can gain access to a wider user base of Bitcoiners seeking to interact with the Rootstock ecosystem.
