How Share Protected Copy Traders from Malicious Tokens with Blockaid

Introduction

Share is a fast, fun, and easy way to share your transactions. Share indexes every transaction from every onchain app, in real time, turning raw blockchain data into human readable events ready to be contextualized.

Every wallet address and Farcaster account automatically has a Share profile complete with their transactions, tokens, and collectibles.

Share’s pro terminal features give traders the tools they need to trade faster and smarter — live charts that update with every trade, holders updated in real time, best price execution through 0x and Jupiter, trade with any existing wallet, and see real time balances across all connected Ethereum and Solana wallets.

The Challenge: Malicious tokens spreading through social trading feeds

Share connects social discovery with instant execution, however, this can be risky for users. A malicious token can quickly propagate through Share’s social feed and pose a threat to hundreds of users.

Share's infrastructure, built by founding engineer Subrat Prasad, was designed to handle this exact challenge: stopping malicious tokens before they spread to hundreds of users through Share’s social feed. Protecting our users without restricting legitimate activity became critical to scaling safely.

The Solution: Blockaid Token Scanning API

Share architected an inline token validation layer that invokes Blockaid’s simulation and classification APIs to analyze transactions and contracts in real time before execution.

This allowed Share to flag malicious contracts, prevent risky transactions, protect copy traders from mirrored scams, and allow safe engagement with legitimate airdrops. The integration was easily completed in a couple of days, with minimal performance impact. Because Blockaid operates at high speed, Share was able to maintain a fast social trading experience while adding a security layer underneath.

"Share's social graph means one compromised wallet can cascade to hundreds of copy traders. I built security into the transaction flow at the infrastructure level without adding latency. Blockaid was the only solution that could give us real-time detection accuracy at the speed our users expect.” — Subrat Prasad, Founding Engineer

Results

In the six months since integration, Blockaid has scanned over 222,000 unique token signals for Share, identifying 27,766 malicious entities—roughly 1 in 8 tokens evaluated. 

Of the scams Blockaid prevented, 77% were rug pulls, honeypots, and airdrop pattern abuse, common attack types that social trading platforms like Share is exposed to. 

Why Blockaid: Intelligent, real-time token scanning

Blockaid's token scanning is powered by a multi-layer detection engine that cross-references five intelligence layers: code analysis (static + LLM), onchain behavior monitoring, market signal analysis, funds trail tracing, and metadata verification. This approach delivers best-in-class true positive pre-rugpull detection rates with sub-one-minute time-to-detect, identifying threats like honeypots, wash trading, and rugpull setups before users are exposed.

The engine covers both EVM and major non-EVM chains including Solana through a single unified API, with webhook support for continuous token monitoring. Blockaid absorbs the ongoing operational complexity of keeping detections current against evolving threats, so teams like Share can focus on building their product rather than maintaining a security operation.
