Cryptographically auditable AI for credit unions

Ship AI agents into regulated workflows. With examiner-grade audit trails. Built on Symitar.

CharterOS is the agentic operating system for credit unions. Every decision an agent makes is cryptographically signed, verifiable offline by examiners, and bounded by your institution's policy.

Why CharterOS

A platform built for what generic AI cannot do in regulated banking.

01 / Audit

Cryptographically auditable

Every agent decision is signed with Ed25519 and a post-quantum signature, then written to WORM storage with seven-year retention. Examiners verify decisions offline, without trusting our infrastructure.

02 / Depth

Symitar-native depth

Direct integration across SymXchange, jBASE, REPGEN, and PowerOn. Built from eighteen years of operator experience in regulated payments and core banking systems.

03 / Platform

One substrate, four agents

Loan decisioning, fraud detection, payment disputes, and anti-money laundering share the same governance, policy, and audit layers. Ship once, deploy across workflows.

The platform

Four agents on one substrate, shipping over twelve months.

How it works

One loan decision. Six steps. Signed end to end.

Step 01

Load institutional policy

CharterOS loads the credit union's specific loan policy, rules, and risk tolerances into the agent's bounded reasoning scope.

Step 02

Pull from Symitar

Member account history, debt-to-income ratios, and credit signals are fetched directly from Symitar through SymXchange.

Step 03

Tokenize sensitive data

Sensitive fields are tokenized through HashiCorp Vault before the AI sees any raw member data. The model operates on tokens only.

Step 04

Reason

Claude on AWS Bedrock reasons over the institutional policy and the tokenized member record. Returns a decision with a full reasoning trace.

Step 05

Fail-closed governance gate

The proposed decision is verified against the credit union's policy. Out-of-bounds requests block here, before any commit to the core.

Step 06

Sign and store

The decision envelope is signed with Ed25519 and a post-quantum signature, then written to WORM storage with seven-year retention. NCUA examiners verify offline.

Talk to us

Building with credit unions on Symitar.

We are early. We are selective about who we work with. If you operate a credit union, lead a CUSO, or invest in vertical AI for regulated industries, we would value a conversation.

Who we are talking to

  • Credit union CIOs and lending officers on Symitar
  • CUSO and CU-adjacent venture investors
  • NCUA examiners interested in agent audit trails
  • Engineers building agentic infrastructure

We will reply within two business days. Submissions are not shared with third parties.
