YBTC.B: Cross-chain Wrapped Native BTC Asset

Overview​

YBTC.B is a wrapped version of Bitlayer's Native BTC, designed to function as a universal cross-chain liquidity standard across both EVM and non-EVM chains. It enables users to deploy native Bitcoin liquidity seamlessly within DeFi ecosystems on multiple networks.

Purpose​

YBTC.B is engineered with the following core objectives:

1. Make BTC Programmable and Usable​

Unlock the value of native BTC by making it accessible and composable across DeFi protocols spanning multiple chains.

2. Create a Unified BTC Liquidity Standard​

Whether on Sui, Avalanche, Plume, Starknet or any other chains, YBTC.B represents a 1:1 Bitcoin-pegged asset—backed and redeemable on demand.

3. Serve as a Cross-chain DeFi Hub Asset​

Acts as the liquidity medium connecting native Bitcoin with yield-generating strategies (Vaults), lending protocols, AMMs, and staking infrastructures across chains.

Key Features​

  • 1:1 Peg to Native BTC
    Each YBTC.B token is fully backed by a corresponding amount of native BTC, either bridged or locked on-chain, and is redeemable at any time.

  • Multi-chain Yield Bearing
    YBTC.B can be deposited into DeFi and CeDeFi Vaults across multiple chains to earn BTC-denominated yield. Strategies include LP farming, lending, and fixed-income RWAs, with automated reward compounding and flexible redemption mechanisms.

  • Cross-chain Composability
    YBTC.B can move freely between Bitlayer, EVM-compatible chains (e.g., Avalanche, Plume), and non-EVM chains (e.g., Sui, Starknet), ensuring fluid capital mobility.

  • Unified Asset Format
    Regardless of the destination chain, YBTC.B maintains a consistent token logic and peg structure, simplifying wallet and protocol integration.

Token Origin & Minting​

Underlying Asset​

YBTC.B is derived from Bitlayer Native BTC, which itself is backed 1:1 by off-chain BTC reserves.

Minting Mechanism​

YBTC.B is minted through verified smart contracts when users bridge BTC into Bitlayer and initiate wrapping via the official bridge infrastructure.

How to Acquire YBTC.B​

  • Bridge from Native BTC
    Use Bitlayer’s official bridge to transfer BTC into Bitlayer Layer 2 and mint YBTC.B directly.

  • Buy on DEXs
    YBTC.B is available on AMMs and liquidity pools across supported chains.

  • Borrow via Lending Platforms
    Supported as a collateral asset or borrowable token via partner DeFi protocols.

YBTC.B represents a foundational component in enabling programmable Bitcoin liquidity across DeFi, bridging native BTC with scalable multi-chain applications.
