Predicate and Blockaid: Real-time Exploit Protection for Digital Asset Issuers

DeFi exploits, wallet drainers, and other attacks designed to steal crypto remain one of the largest obstacles to blockchain adoption. According to TRM Labs, $2.87 billion was stolen across nearly 150 hacks and exploits in 2025 alone. The risk is especially high for stablecoin and RWA issuers. Every tokenized asset they have in circulation is a potential target for theft or vehicle for laundering stolen funds, which makes them less attractive for financial institutions and retail users alike.

That’s why we’re excited to share that Predicate has partnered with Blockaid to give asset issuers automated compliance policies that prevent addresses and smart contracts associated with exploits from interacting with their stablecoins and tokenized assets. Blockaid is an onchain security platform trusted by Coinbase, Uniswap, MetaMask, and others. Its Risk Exposure API delivers real-time signals on addresses and smart contracts tied to active exploits, drainers, and other malicious activity, updated as new incidents are identified. Assets protected by Predicate and Blockaid tap into that data to prevent hackers from using the asset, achieving the safety standards necessary to onboard institutional capital and protect everyday users from malicious actors.

How Predicate + Blockaid protects assets from hackers

The Blockaid integration allows asset issuers on Predicate to create automated policies aimed at two core hacking-related use cases: Mitigation of active DeFi exploits and protections for token holders against drainers.

Cutting off active DeFi exploits

Responding to exploits as an asset issuer is difficult because of the speed required. Unlike other high-risk users issuers screen for, hackers typically start with clean addresses showing no signs of risk. But once an exploit begins, hackers can steal and launder funds within minutes, swapping stolen assets for new tokens and moving them through bridges and mixers before most risk systems can update.  

Asset issuers need an automated solution that can identify and restrict hacker addresses as soon as the exploit is confirmed. And that’s exactly what they get with Predicate and Blockaid.

Blockaid’s Onchain Monitoring platform detects DeFi exploits as soon as they begin and flags hackers’ addresses in real time. Predicate then immediately adds those addresses to issuers’ token blocklists, preventing the hackers from acquiring the asset or restricting them from sending if they already hold it, depending on how the issuer chooses to configure the policy. The integrated solution takes away the time between identification and restriction that DeFi hackers rely on, allowing issuers to protect their assets and facilitate recoveries alongside law enforcement.

Protecting users from drainers

Drainers are malicious smart contracts that trick users into sending them tokens, usually through social engineering techniques like impersonating a legitimate DeFi protocol. Drainers have become one of the most common ways for retail users to lose funds. But with the Predicate-Blockaid integration, issuers can now make their asset immune to identified drainers.

Blockaid tracks known drainer smart contracts across different blockchains. Asset issuers can now create onchain policies that automatically block all identified drainers from receiving their token, meaning that users are protected even if the drainer fools them – the malicious transaction will simply fail.

How it works

Policies in Predicate Asset Compliance function as a set of rules for which addresses cannot interact with the issuer’s token. Each rule declares an attribute that makes an address too high-risk to use the token, with a data source determining whether any given address meets that attribute – if it does, Predicate restricts the address at the token contract level. 

With this partnership, Blockaid’s Risk Exposure API is now available in Predicate as a data source, making rules linked to real-time exploit detection and drainer identification possible. Predicate monitors all data sources and ingests updates from them continually, so there’s virtually no delay between Blockaid publishing an identification and it becoming a live input on an asset’s Predicate policy.

Safer assets are the foundation of blockchain adoption

Hacking and theft are longstanding barriers to blockchain adoption. Institutions hesitate to hold assets that can be stolen and laundered without recourse, and users hesitate to embrace DeFi when one bad transaction signature can empty their wallet. With Predicate and Blockaid, asset issuers can virtually eliminate those risks at the token contract level, and position themselves as a stronger partner for financial institutions and fintechs.
