What's inside Rebar Labs

  1. Overview of Rebar Data Services

    Rebar Data provides comprehensive access to Bitcoin blockchain data, including every block, transaction, and address from genesis. It unifies core blockchain data with metaprotocol activity for Ordinals, Runes, BRC-20, Alkanes, and others. Data can be accessed via the Rebar Data web interface or programmatically through their APIs.

  3. Overview of Rebar Shield private transaction relay

    Rebar Shield is a specialized RPC service that allows Bitcoin transactions to be submitted directly to mining pools, bypassing the public mempool. This creates a private channel for transaction delivery that enhances privacy and eliminates the risk of frontrunning or other MEV-related attacks. It is particularly useful for BRC-20s, Runes, and other Bitcoin metaprotocols, as well as Layer 2 solutions. Shield currently supports Bitcoin mainnet only.

  4. Overview of the Shield API for private Bitcoin transactions

    The Shield API is a relay product that allows users to privately broadcast Bitcoin transactions over secure connections. This ensures that transaction information is not leaked to the public network before the transaction is officially included in a block.

  5. Overview of Rebar Electrum server capabilities

    Rebar Data operates a full Electrum protocol server that allows lightweight wallets and applications to access Bitcoin blockchain data without running a full node. Supported capabilities include:

    • Address history: Full transaction history for any address
    • UTXO queries: Unspent outputs for balance computation
    • Transaction broadcast: Submit signed transactions
    • Block headers: Retrieve and verify headers for SPV validation
    • Fee estimation: Current fee rate estimates
    • Subscriptions: Real-time notifications for address activity (receiving or spending funds)

  6. Overview of Rebar Labs Bitcoin Infrastructure

    Rebar Labs provides MEV-aware infrastructure for Bitcoin designed to support decentralization, security, and fairness. Their offerings include private transaction relays, blockchain data, and metaprotocol indexing (supporting 6+ metaprotocols). The platform is intended for developers building metaprotocol-aware wallets, front-running solutions, trading insight tools, and on-chain analysis tools.

  7. Overview of Rebar Labs JSON-RPC capabilities

    The Rebar Labs JSON-RPC endpoint provides low-latency access to Bitcoin L1 data and the Rebar metaprotocol execution layer. Key capabilities include:

    • Chain-Level Reads: Retrieve blocks, transactions, and mempool entries by txid, outpoint, or script.
    • Execution Introspection: Dry-run transactions and inspect metaprotocol state and transaction flows before they reach the mempool.
    • Indexed Overlays: Access augmented metadata keyed to native Bitcoin primitives for analytics and wallets.
    • Event Polling: Poll for state changes with millisecond-grade latency for trading bots and alerting systems.

  8. Overview of Rebar Data Metaprotocol Indexing

    Rebar Data provides API access to Bitcoin metaprotocol state (token balances, smart contract state, inscriptions, and naming data) by running indexers that replay blocks and parse embedded data such as inscriptions, OP_RETURN messages, and witness envelopes. Because metaprotocol state is not part of Bitcoin's native consensus, Rebar indexers produce verification hashes to allow developers to confirm consistency against other protocol implementations.

  9. Overview of Rebar Shield for Bitcoin Privacy

    Rebar Shield is designed for privacy and MEV protection on Bitcoin. It allows users to submit transactions directly to mining pools, effectively bypassing the public mempool to send transactions privately. It is accessed via a JSON-RPC API and pricing is based on transaction size, with feerates determined by the mining pools.

  10. Overview of the Rebar Data API

    The Rebar Data API is a RESTful interface providing real-time and historical access to Bitcoin-native assets and metaprotocol activity on Bitcoin L1. It is designed for production infrastructure requiring verifiable data for protocols such as Runes and Alkanes while preserving L1 security. All API endpoints require authentication via an API key obtained from the Rebar Data portal.

  11. Overview of Rebar Data for Bitcoin Transparency

    Rebar Data provides real-time and historical access to Bitcoin blockchain data, unifying support for Ordinals, Runes, BRC-20, Alkanes, and other metaprotocols. It is used for integrating wallets, building on-chain dApps, low-latency query access, research, analytics, and monitoring. Access requires a Rebar Data account and API key. Pricing is based on API call volume.

  12. Overview of Rebar Labs Bitcoin Infrastructure

    Rebar Labs provides MEV-aware infrastructure and research for the Bitcoin ecosystem. Their offerings focus on three primary areas:

    1. Infrastructure: Providing an alternative to the public mempool via private transactions to protect users from frontrunning and censorship, while creating new revenue streams for miners.
    2. Products: Data products and dashboards for analyzing on-chain activity, specifically targeting new protocols like Runes and BRC-20s.
    3. Research: Analysis and reporting on emerging Bitcoin activities and MEV (Maximal Extractable Value).
