OroBit (XRB) is a Bitcoin-native protocol that layers smart-contract functionality onto Bitcoin's base layer using its own "SCL" (Smart Contract Language) alongside the Lightning Network. It is not an Ethereum, BNB Chain, or Solana token; no EVM or Solana contract address exists for XRB.
The project runs its own proprietary network with a dedicated block explorer at explorer.orobit.ai. OroBit is categorized under "Smart Contract Platform" and "Layer 2" designations, with its network listed as "Orobit (proprietary blockchain)." XRB launched in 2025 and trades on centralized exchanges including MEXC and LBank as of 2026-08-31.
OroBit differentiates itself by embedding programmability directly into Bitcoin's base layer instead of issuing a token on Ethereum, BNB Chain, or Solana. Its proprietary SCL (Smart Contract Language) protocol combines Bitcoin Layer 1 settlement with Lightning Network payment rails, positioning XRB as a Bitcoin-native alternative to EVM- and Solana-based smart contract platforms.
The project runs its own network and block explorer rather than relying on a shared virtual machine environment used by comparable smart-contract chains.
XRB is the native utility token of the OroBit protocol, used to settle transactions and smart-contract activity within its Bitcoin Layer 1 and Lightning Network-based SCL environment.
OroBit's XRB token has a maximum and total supply fixed at 500,000,000 XRB. Total supply already equals maximum supply, making XRB's issuance model non-inflationary with no further token minting possible under the current cap.
XRB, OroBit's native token, launched in 2025. It is currently listed and traded on centralized exchanges, including MEXC and LBank, rather than through a decentralized on-chain launch venue.
OroBit operates as a Bitcoin-native Layer 2 protocol built on Bitcoin Layer 1 combined with the Lightning Network, inheriting Bitcoin's proof-of-work-based settlement finality. It is not deployed on Ethereum, BNB Chain, or Solana.
The protocol uses its own proprietary "SCL" (Smart Contract Language) framework rather than participating in a shared EVM or Solana validator set.
The project operates under the name OroBit, with its official website at orobit.ai and a dedicated block explorer at explorer.orobit.ai. A whitepaper is hosted at docs.orobit.ai/whitepaper.pdf.
Official communication channels include the X account @Orobit_Official and the Telegram channel @orobit_official.
CertiK assigns OroBit a security rating of 3.5. XRB trades only on two centralized exchanges, MEXC and LBank, with 24-hour volume of roughly $200,000 to $550,000 — a small fraction of its approximately $870–880 million fully diluted valuation, indicating thin liquidity relative to that valuation.
