Owner route
OWNER WALLET + APPLE PASSKEY 48-HOUR WAIT OWNER EOA
The familiar destination, deliberately slowed so there is time to notice and respond.
2FA BY SOLIDMETRICS · ARBITRUM ONE
DESIGN PREVIEW · CONTRACTS ARE NOT LIVE · DEPLOYMENT DISABLED
A stolen wallet key alone isn’t enough.
The planned immutable vault protects ETH, USDC, USDT and WBTC. Returning funds to your owner wallet requires your Apple passkey and a 48-hour wait. Emergency rescue is immediate.
TWO IMMUTABLE DESTINATIONS
Two routes. One vault.
The planned contract gives Solidmetrics no route to add a third destination, redirect a live vault, or move the assets inside it.
Emergency route
OWNER OR EMERGENCY WALLET IMMEDIATE RESCUE EMERGENCY EOA
A direct path to the separate emergency address fixed when the vault is created.
THE RESPONSE WINDOW
48 hours to notice. One action to rescue.
00:00
Owner exit scheduled
The standard route begins only after the owner wallet and Apple passkey approve it.
≤ 00:01
Sentinel attempts alerts
Verified email and Telegram notifications are attempted within 60 seconds under normal conditions.
00:01–48:00
Emergency rescue stays open
The owner or emergency wallet can send the vault to its immutable emergency address at any time.
48:00
Owner route unlocks
Owner finalization and emergency rescue become competing on-chain transactions; neither has ordering priority.
WITHDRAWAL SENTINEL
The contract protects the route. The Sentinel helps you notice.
Verified email and Telegram alerts happen off-chain. They contain no balance or asset list and have no authority over your vault.
Both channels are recommended. At least one verified notification channel is required before vault creation.
EMERGENCY RECOVERY
The website is not your recovery key.
Once the audited contracts launch, owner or emergency signing authority can still initiate recovery through the verified contract even if this website disappears.
Ordinary passkey withdrawal may depend on the secure passkey domain; emergency recovery does not.
Before launch, this section will publish the verified contract address, ABI, exact explorer instructions, and open-source recovery tool. Until then it is a design preview, not an executable guide.
SUPPORTED ENVIRONMENT
A deliberately narrow V1.
- Network
- Arbitrum One
- Assets
- ETH · USDC · USDT · WBTC
- Apple environment
- iPhone Safari on supported iOS 17+ and MacBook Safari on supported macOS 14+, using Apple passkey
- Ownership
- One immutable owner EOA and one distinct emergency EOA
INSPECTABLE SECURITY MODEL
Inspect every rule before using it.
- Immutable, non-upgradeable live-vault design
- Verified source and reproducible bytecode required before launch
- No planned Solidmetrics authority over live-vault assets
- V12 and adversarial LLM review required before launch
Website preview only: the contracts have not been built, audited, adversarially tested, or approved for mainnet.
ONE-TIME CREATION FEE
$25 USDC. One vault. No subscription.
At launch, you pay deployment gas and ordinary owner-withdrawal gas. Solidmetrics plans to sponsor supported emergency-rescue gas only while its relayer service operates. Direct self-funded recovery remains available.
DESIGN PREVIEW DISCLOSURE
No system is 100% safe.
2FA by Solidmetrics is designed to reduce the risk of asset theft after an owner-key compromise. It does not eliminate every smart-contract, blockchain, token, device, user, or operational risk.
