What it does
Blockaid offers transaction-screening integrations for wallets, monitoring for deployed assets and protocols, and signing controls for institutional wallets. Teams choose the product that matches where they need to inspect activity or enforce a policy.
Put checks in a wallet or application
End User Protection supplies API and SDK integrations for scanning transactions, addresses, tokens and decentralized applications. A wallet team can use the returned assessment in its signing flow. Blockaid describes support for EVM and non-EVM networks, with implementation support for custom integrations.
Monitor deployments or review a treasury signature
Onchain Monitoring starts with an inventory of assets, contracts and protocols in scope. Its listed monitors include owner changes, contract upgrades, oracle deviations, liquidity conditions and events in connected protocols. The company says its onboarding team helps map that environment and configure the monitors.
Cosigner serves a different point in the process: an institutional wallet's proposed transaction. It shows a simulated transaction flow as an interactive graph and lets operators configure policies based on labels. Listed integrations include Safe, Fireblocks, Squads and Utila. Alerts and automated actions can then be tied to the signing workflow.
The public site directs teams to a demo. Confirm the supported networks, wallet integration and policy behavior for the intended deployment during that process.
