Spearbit and @Cantinaxyz are now officially united. What began as two parts of the same mission has evolved into a shared environment - combining high-signal reviews with adaptive, scalable security solutions for end-to-end coverage. Here's why this matters.

A new high-touch security review: @Monad x @Spearbit. Working in coordination with @asymmetric_re, Spearbit's work will focus on core systems: consensus protocol, execution environment and EVM pipeline, all architected for performance. A pleasure supporting the security of

Explore the full technical breakdown of Spearbit’s DePIN security framework in our latest blog:.

Operating in DePIN? Secure your infrastructure with lifecycle-aligned reviews. Contact us:

Effective DePIN security begins with trust boundary modeling. The reviews should map relationships between contributors, coordination systems, and administrative controls. This structure accounts for spoofed devices, false reporting, and orchestrated manipulation.

Security domains in DePIN include:. • Contract logic and staking rules.• Hardware trust assumptions.• Orchestration systems and APIs.• Off-chain data pipelines.• Governance and upgrade permissions. We address each independently and model them collectively.

Reward mechanisms in DePIN protocols are uniquely exposed to economic manipulation. Spearbit-led reviews prioritize Sybil resistance, incentive modeling, and behavioral enforcement to prevent degradation through false participation and collusion.

Spearbit’s approach maps these layers explicitly, eliminating blind spots in security scope.

DePIN systems operate across on-chain contracts, physical devices, backend logic, and governance models. Each layer introduces independent attack surfaces.

DePIN organizations coordinate physical infrastructure through DeFi. With over $34B in combined value, they require security approaches tailored to adversarial, multi-layered environments. Let’s dive in.

Kicking off a cryptography-focused review: @Midl_xyz × Cantina. Midl is an execution environment that brings smart contracts to Bitcoin, opening the door to a new generation of versatile dApps. Everything once possible on Ethereum can now be built on Bitcoin with Midl. Node

The focused @Optimism × Spearbit security reviews for Upgrade 16 and the core protocol infrastructure are now complete. These engagements covered deployment verification logic, contract upgrade management, and system configuration integrity across the OP Stack. Links below.

Security for autonomous execution begins before production. Explore how we test agent behavior across failure modes and design boundaries:

If your systems rely on agent-driven execution, we help define boundaries, simulate adversarial input, and validate behavior before it reaches production. Contact our team:

We simulate edge conditions across prompt injection, output validation, and fallback behavior. Reviews confirm execution intent, trace authority, and expose where live systems break from design.

Inference-driven logic responds to market data, protocol state, and user input. Without enforcement boundaries, agents can trigger transactions based on malformed prompts, unverified assumptions, or adversarial context.

Autonomous agents are live in DeFi. They allocate, rebalance, and execute across protocols with minimal oversight. Spearbit evaluates these systems under pressure to surface behaviors static analysis cannot reveal. Details below.

We’re hearing the signals, there’s an industry shift coming. @soniclabs. We're always ready when systems evolve. Get ready, July 17.

The high-signal @MorphoLabs × @Spearbit security review is now finalized. This expert-led engagement focused on the Morpho Vaults v2 system, including adapter architecture, interest accrual behavior, and governance-driven parameters.
