SCAR Corpus

231,269 Solidity smart contracts for sparse retrieval over smart contract code. Used as the SAE pretraining corpus and the document collection for SCAR retrieval training and evaluation.

Note (September 2026)

The corpus itself is unaffected, but the evaluation numbers quoted on related cards were measured on a leaked split (see the Known issue on scar-eval), and the SAE trained on this corpus and shipped in scar-weights collapsed at the end of its training (see that card). Corrected results follow with the October 2026 preprint.

Sources

DISL — decompiled smart contracts (sampled 120k after deduplication)
slither-audited — big-multilabel split (47k contracts with vulnerability labels)
SmartBugs Wild — 47k real-world deployed contracts
FORGE-Curated — audit report code (oldest 60% by report date, ~15k contracts)
DeFiVulnLabs — 48 vulnerability type demonstrations

Quality Filters

Removed contracts < 50 lines (insufficient context for meaningful features)
Removed import-only files (>80% import statements)
Hash-based deduplication on normalized source (strips comments, whitespace, SPDX headers, pragma directives)
Cross-source deduplication

Usage

from datasets import load_dataset
ds = load_dataset("Farseen0/scar-corpus", split="train")

Coverage

The corpus provides broad coverage of both benign and vulnerable Solidity patterns, ensuring the SAE learns features relevant to the full spectrum of smart contract code. Vulnerability classes represented include:

Reentrancy and external-call patterns
Access-control bugs
Integer overflow / underflow (pre-0.8 contracts)
Oracle manipulation and flash-loan attacks
ERC-20 / ERC-721 implementation bugs
Missing validation in transfer / withdraw functions

🗂️ All SCAR artifacts (Collection)
scar-pairs — 7,552 training pairs (uses this corpus as the document pool)
scar-eval — 838 held-out evaluation pairs
scar-weights — trained model weights (SAE pretrained on this corpus)
