Solon · Modules

Seven modules.
One control plane.

Each module closes one of the five gates between agent adoption and production. Together, they form the control plane.

01 · Policy Engine The core

The brain that decides.

Declarative rule evaluation in microseconds.

Spend limits, whitelists, time windows, role separation, risk scoring, custom policies — all expressed in a typed DSL, version-controlled in Git, evaluated before any signing request is emitted.

  • { } Typed policy DSL policy-dsl v2 · git-versioned · code-review friendly
  • Sub-millisecond p99 parallel evaluation · cached compilation
  • Hot-reloadable no restart · per-agent scoped · audit-tracked
02 · Audit Trail Evidence

Immutable.
Searchable.

Defensible by design.

Every evaluation captured — agent ID, prompt hash, model version, tool params, context, decision, reviewer. Stored in S3 with a Merkle root anchored on-chain.

  • Merkle-anchored tamper-evident · on-chain proof
  • 📑 SOC 2 / ISO 27001 / SOX structured exports · auditor-ready
03 · Approval

Humans,
when needed.

Threshold-triggered human review. Slack, email, and approval-UI integration with SLA tracking and configurable escalation paths.

  • Slack
  • Email
  • Webhook
  • SLA tracking
  • Multi-step
04 · Compliance

Screened
at the edge.

OFAC and EU sanctioned-address lists, Chainalysis-style risk scores, Travel Rule for cross-jurisdiction transfers, automatic AML evidence.

  • Chainalysis
  • TRM Labs
  • OFAC
  • Travel Rule
05 · Multi-Agent

Many agents,
one ledger.

Independent budget pools per agent. Cross-agent message bus for task handoff. Single-agent kill switch — without affecting others.

  • Per-agent budgets
  • Inter-agent bus
  • Kill-switch
  • Dashboard
06 · ERP Integration Last mile

From chain
to ledger.

So spent crypto looks like finance-issued money.

SAP, Oracle, NetSuite, Xero, QuickBooks adapters out of the box. GAAP / IFRS classification. Automated journal entries. Tax-ready exports for AML and cross-border filings.

  • SAP · Oracle · NetSuite · Xero · QuickBooks official adapters · field-mapped · idempotent
  • 📊 GAAP / IFRS classification COGS · OpEx · CapEx · auto-classified
07 · Error Recovery Safety net

Time, before
commitment.

A revocation window is the only honest defense against hallucination.

Delayed execution pools (T+0 / T+1 / T+N). Revocation windows for high-stakes transactions. Prompt-injection detection. Circuit breakers that suspend agents on anomaly — automatically, surgically.

  • Delayed execution pools T+0 · T+1 · T+N · configurable per policy
  • Circuit breakers anomaly detection · per-agent isolation
02 · The Mapping

Five gates.
Closed by seven modules.

Each of the five enterprise pain points is addressed by a primary module — and reinforced by one or two supporting modules.

01 Gate
Permission granularity is too coarse.
◆ Policy Engine Multi-Agent
02 Gate
Audit trail is missing.
◆ Audit Trail Policy Engine
03 Gate
Multi-agent fund isolation.
◆ Multi-Agent Policy Engine Error Recovery
04 Gate
Error recovery is unbuilt.
◆ Error Recovery Approval Compliance
05 Gate
Disconnect from ERP & accounting.
◆ ERP Integration Audit Trail Compliance

A control plane,
for the agents you're about to deploy.

Built between agents and money. Non-custodial. Production-ready.
