iBTC’s Multi-Chain Powerhouse

iBTC transcends a single blockchain, bringing secure Bitcoin liquidity to a growing ecosystem of chains. By leveraging its bridgeless, Layer 1 design, iBTC ensures fast, cost-effective transactions across Ethereum, Layer 2s, and beyond. Explore the networks powering iBTC’s growth ambition and future expansions.

Ethereum

  • Role: Primary chain for iBTC minting and DeFi integration.

  • Technical Detail: iBTC operates as an ERC20 token, managed by the AttestorManager smart contract, with Chainlink PoR verifying reserves (e.g., Arbitrum feed).

  • Use Case: Staking on Symbiotic, lending on Aave, liquidity on Curve.

  • Performance: Gas costs vary; Arbitrum recommended for efficiency.

Arbitrum

  • Role: Layer 2 scaling solution for cost-effective iBTC transactions.

  • Technical Detail: Uses Optimistic Rollups, with iBTC integrated via cross-chain messaging, backed by PoR (feed).

  • Use Case: High-frequency trading and liquidity provision (e.g., dYdX futures).

  • Performance: 10x lower gas fees than Ethereum mainnet.

Optimism

  • Role: Another Layer 2 for scalable iBTC deployment.

  • Technical Detail: Optimistic Rollups ensure fast finality, with iBTC minting validated by Attestor Network.

  • Use Case: Lending on Morpho, staking on Mellow vaults.

  • Performance: Comparable to Arbitrum, with growing DeFi adoption.

Base

  • Role: Coinbase-backed Layer 2 for iBTC expansion.

  • Technical Detail: Uses Optimistic Rollups, with PoR feed (Base feed) ensuring reserve integrity.

  • Use Case: Institutional liquidity pools, trading with Cumberland.

  • Performance: Low-cost, high-throughput, ideal for retail users.

XRPL (Ripple)

  • Role: Unique cross-chain support, the only wrapped BTC here.

  • Technical Detail: iBTC integrates via XRPL’s sidechain bridge alternative, secured by multisig vaults and attestors.

  • Use Case: Cross-border DeFi and institutional trading.

  • Performance: Fast settlement (3-5 seconds), attracting global LPs.

Future Expansions

  • StarkNet: Planned integration for ZK-rollup efficiency and yield incentives.

  • Canton: Privacy-enabled CeDeFi hub for institutional flows.
