Agent wallets,
on a leash.
Three-layer validation on every transaction. Deterministic rules, simulation, AI risk scoring — all before a single wei moves.
Secure your agent in 60 seconds
Connect, configure, deploy. Your AI agent gets a secured Sigil Wallet with policy guardrails built in.
Deploy Your Sigil Wallet
Connect your wallet and deploy an ERC-4337 Sigil Wallet. This is the on-chain wallet that holds your funds and executes transactions.
Set Policies & Fund It
Pick a strategy template with spending limits, target whitelists, and token policies. Fund the Sigil Wallet — this is where your agent's budget lives.
Generate Agent API Key
Create an API key for your agent — this is for authentication only, not a wallet. Your agent submits transactions through the Guardian API; the Sigil account executes them.
// OpenClaw — one command, verified on ClawdHub
clawdhub install sigil-security
// Eliza — npm plugin (13 actions)
import { sigilPlugin } from '@sigil-protocol/eliza';
// Any framework — TypeScript SDK
import { SigilSDK } from '@sigil-protocol/sdk';
// Universal — REST API
POST https://api.sigil.codes/v1/evaluate
First-class OpenClaw integration
One command gives your OpenClaw agent secure wallet management — deploy wallets, evaluate transactions, manage session keys, and more. All through the 3-layer Guardian pipeline.
clawdhub install sigil-securityView on ClawdHub →Works with the frameworks and tools you already use.
Built for autonomous wallets, not humans clicking buttons
Your agent gets a leash, not a blank check. Session keys with time limits, spend caps, and target restrictions.
Session Keys
Time-limited, scope-limited ephemeral keys. Your agent gets 4 hours and a spend cap — not the master key.
Policy Engine
Per-tx limits, daily caps, target whitelist, function whitelist, token allowance policies. All enforced on-chain.
Emergency Freeze
One call freezes everything. Withdraw funds even while frozen. The kill switch you hope you never need.
Social Recovery
Lost your key? N-of-M trusted guardians recover your Sigil Wallet after a configurable safety delay.
ERC-4337 Native
Sigil Wallet with gas abstraction. No private key needed by the agent — just a session key with guardrails.
UUPS Upgradeable
Upgrade your Sigil Wallet logic with 24h timelock + guardian co-sign. Future-proof without redeploying.
Secure your Polymarket agent
AI agents trading on Polymarket need guardrails. Sigil deploys on Polygon with purpose-built limits for prediction markets.
Bet Limits
Cap per-trade size and daily volume. Your agent can't YOLO your entire bankroll on a single market.
Contract Whitelist
Restrict your agent to verified Polymarket contracts only. No interacting with random tokens or drainers.
Emergency Kill Switch
Market going sideways? Freeze your agent instantly. Withdraw funds while frozen. You stay in control.

Three layers. Zero trust.
Every transaction passes through all three layers before your Guardian co-signs. If any layer flags it, it's blocked.
Deterministic Rules
Spending limits, target whitelist, function whitelist, velocity checks, token allowance policies.
Transaction Simulation
Dry-run the full transaction. Catches reverts, sandwich attacks, unexpected approvals, value drain.
AI Risk Scoring
LLM analyzes transaction context, target reputation, historical patterns. Scores 1–100.
One fee. No subscriptions.
Pay once when you deploy. Every feature included. No monthly bills, no hidden charges.
Includes: Sigil Wallet deployment, 3-layer validation, session keys, recovery, upgrades, SDK, API access.
Validation costs (~$0.003/tx) absorbed by protocol. You only pay gas.

OpenClaw Skill
Verified on ClawdHub. One command install for any OpenClaw agent.
Eliza Plugin
13 actions, evaluator, wallet provider. npm install and go.
TypeScript SDK
Session keys, recovery, upgrades, token policies, multicall.
REST API
Evaluate transactions, manage wallets, query status.
MCP Server
Model Context Protocol tools for any AI agent framework.
Your keys never touch our servers.
Sigil is non-custodial by design. We validate transactions — we don't control wallets.
Your keys, your control
Origin Wallet key, Agent Wallet key, session keys, recovery guardians — all generated and stored on your side. We never see them.
Guardian validates, never initiates
The Guardian co-signer can only approve transactions after they pass all three security layers. It cannot move funds or act alone.
You can always override
Emergency freeze, withdrawal, key rotation — all Origin Wallet-only on-chain functions. If our servers go offline, your Sigil Wallet still works.
