Core infrastructure

The core infrastructure for secure agentic execution

Session Keys

Issue temporary, delegated credentials directly from your dashboard. Empower your AI agents to sign fast transactions without ever exposing your master private key.

On-Chain Guardrails

Enforce strict programmatic limits natively on Arbitrum. Automatically intercept transactions to block unapproved protocols and freeze anomalous spending caps.

Centralized Gas Tanks

Isolate operational gas from your agent's core capital. Top up a single pool in USDC to seamlessly sponsor gasless executions across multiple smart accounts.

Integration stack

Why Phylax

The immutable control layer built for autonomous AI safety

Isolated Agent Runtimes

Never expose your master private key to the AI environment. Provision temporary session keys with strict programmatic boundaries directly from your dashboard.

Separated Gas & Capital

Fuel your centralized gas tank independently. AI agents spend raw USDC capital exactly as allocated, with zero hidden gas deductions from their working balances.

On-Chain Policy, Not Prompts

Prompt injections, hallucinations, or backend exploits hit an immutable contract boundary. Malicious transactions revert instantly at the blockchain level.
