AI Agent Policy Infrastructure
Giving autonomous software unconstrained custody of private keys is a catastrophic design flaw. Apraxus wraps agent wallets in cryptographically enforced policy envelopes with deterministic spend ceilings.
Delegated Key Derivation
Human master operators sign cryptographic root delegations. The agent executes via ephemeral Ed25519 sub-keys with cryptographic boundaries bound to its public key digest.
Time-Lock Spending Ceilings
Prevents infinite drain loops. Each envelope limits maximum cumulative spending across rolling windows (e.g. 50 USDC/hr), validated deterministically on-chain before transaction queueing.
Instant State Revocation
In the event of an anomalous prompt injection or aberrant model behavior, operators broadcast a single-byte revocation payload that instantly invalidates the envelope across all active network nodes.
APXS Agent Payment Console
Test a policy-controlled payment flow where an AI agent can only spend within operator-defined boundaries.
Delegated Key Hierarchy
Human operators hold sovereign master keys. Ephemeral agent sub-keys are derived using Ed25519 scalar multiplication bound to a cryptographic policy envelope digest.
Rolling Time Windows
Spending limits are tracked via rolling epoch accumulators. Even if an agent loops infinitely, cumulative expenditures cannot exceed the operator’s predefined ceiling.
Deterministic Revocation
Single-byte emergency revocation payloads propagate through the mempool instantly, rendering rogue sub-keys invalid across all active validators in <100ms.
