What is Ghost ?
Ghost is an indexing stack incluiding 2 products, GhostLogs and GhostGraph. A core member of Ghost team is @chrischang43 the third gigachad on Abstract's discord.
GhostLogs allow you to retroactively and permissionlessly modify existing smart contracts to add custom, gasless events and new view functions.
Ghostlogs runs in anoffchaincontext
offchaincontextWhen you add custom, gasless events to a smart contract with GhostLogs, they are emitted in an offchain context while still able to read onchain state. That means they are verifiable while incurring no onchain fees
Why GhostLog ?
Offchain Event Logging: With platforms like GhostLogs, you can now emit non-critical event logs in offchain mode. This allows users to avoid paying extra gas fees since events run in an isolated, yet verifiable, offchain fork.
Retroactive Event Addition: If you are analyzing contracts or building an indexer and missing essential events, GhostLogs lets you retroactively add the exact events you need. This enables you to surface state changes in any detail without relying on low-level traces, saving time and focusing more on analysis.

How to start ?
You can join the private beta of GhostLogs, visit https://app.ghostlogs.xyz/sign-up to sign up. Once you are whitelisted, see Getting Started to set up a ghost fork.
Supported blockchains : Ethereum mainnet / Base mainnet
Demos
GhostGraph is a data indexing framework that makes it easy to create subgraphs for smart contracts, all while staying in Solidity. That means less context switching and faster time-to-market.
Why GhostGraph ?
Unified Language: Write your indexers in Solidity. GhostGraph's goal is to do for indexers what Forge/Foundry did for smart contract testing.
Seamless Integration: Integrate indexers into Solidity projects and re-use protocol code and logic.
Indexing Performance: Blazingly fast indexing. Benchmarks forthcoming!
