Core
AI-Powered Wallet Operations
Describe intent in natural language. Ledgr plans, simulates, and executes with full transparency at every step.
Simulate. Audit.
Execute.
Ledgr is an AI wallet OS built for reliability — every transaction is simulated before execution, every action is audited, and every decision is traceable.

Capabilities
Built for financial-grade reliability
Every capability exists because AI systems operating on financial infrastructure require it — not because it looks good on a landing page.
Safety
Simulation Before Execution
Every transaction is dry-run on Sepolia before your wallet signs. No surprises on-chain.
Audit
Real-Time Audit Logs
Every agent action and tool call is logged with timestamps in an append-only audit trail.
Security
Security Supervisor
An independent layer reviews planned actions against injection guards, rate limits, and spend caps.
Limits
Spending Limits
Per-session and per-transaction limits enforced by architecture — not by model behavior.
Transparency
Reasoning Trace
Expand the full reasoning path behind every decision. No black boxes in financial operations.
Network
Sepolia Integration
Native testnet support with full transaction lifecycle from simulation to confirmation.
Architecture
Wallet Abstraction
Clean separation between intent, planning, execution, and wallet provider. Modular by design.
Architecture
Typed execution pipeline, end to end
Every operation flows through a deterministic pipeline with safety checks at each boundary. Nothing is implicit.

Security & Reliability
Reliable by architecture
AI systems for financial actions must be reliable by architecture — not by prompt engineering or trust.
01
Simulation Before Actuation
No transaction reaches the chain without passing a full simulation first.

02
Immutable Audit Logs
Every agent decision and tool invocation is written to an append-only log.
Structured · typed · queryable
03
Typed Execution Pipeline
The agent-to-blockchain path is fully typed. Malformed inputs fail at the boundary.

04
Safety Supervisor
Monitors spending limits, rate limits, and anomalous patterns in real time.
CircuitBreaker on repeated failures
05
Idempotency Protection
Every operation carries a unique key. Duplicates are deduplicated before the wallet.
Safe under network retry
06
Spending Limits
Per-session and per-transaction caps enforced before execution — not after.
SpendTracker · hard limits
Zero trust. Full transparency.
Every action logged. Every decision traceable. Every execution auditable.
