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

GhostLogs allow you to retroactively and permissionlessly modify existing smart contracts to add custom, gasless events and new view functions.

Ghostlogs runs in anoffchaincontext

When 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 ?

1. 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.

2. 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.

Key Features

• Inject custom, gasless events into existing smart contracts with the GhostLogs in-browser IDE

• Seamlessly rerun historical transactions with your custom modifications to emit your new events (backfilling)

• Spin up a GhostFork RPC endpoint that tracks the upstream chain while using your modified contracts to emit new gasless events and expose new view functions

• Export data to third-parties like Dune Analytics or query directly from Flipside using LiveQuery

Use Cases

• Missing or Incomplete Events

• Gas-Optimized Smart Contract

• Developer Experience

• Robust Proprietary Analytics

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

GhostLog demo w/ Uniswap V3

GhostLog demo w/ Delegate Cash V1

GhostGraph

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 ?

1. Unified Language: Write your indexers in Solidity. GhostGraph's goal is to do for indexers what Forge/Foundry did for smart contract testing.

2. Seamless Integration: Integrate indexers into Solidity projects and re-use protocol code and logic.

3. Indexing Performance: Blazingly fast indexing. Benchmarks forthcoming!

How to start ?

You can sign up for GhostGraph here. Once you are ready, see Getting Started to create a graph.

Supported blockchains : Ethereum / Base / Blast / Abstract testnet / Berachain testnet
