Non-custodial by design
Solid is a non-custodial platform. Your funds are held in a smart contract wallet that only you can authorize. Nobody at Solid — or anywhere else — can move your assets without your explicit approval.
There are no seed phrases to manage. Your wallet is secured by passkeys tied to your device, protected by biometrics or PIN.
Safe smart account infrastructure
Every Solid account is powered by a Safe smart account — the same battle-tested infrastructure used by major DAOs and DeFi protocols to hold billions of dollars.
Key properties:
Multisig-level security, without manual setup
Gasless transactions via paymasters
Account recovery without seed phrases
Programmable controls for sensitive actions
Passkey login & secure key management (Turnkey)
Solid uses passkeys for authentication, backed by Turnkey — a specialist key management infrastructure provider.
No passwords
No seed phrases
Private keys never leave your device
Passkeys are phishing-resistant and bound to your device's secure hardware
Turnkey converts your passkey authentication into chain-compatible signatures, enabling onchain actions while maintaining strong security guarantees.
Real-time threat monitoring (Check Point)
Solid integrates Check Point, a global cybersecurity leader listed on NASDAQ and trusted by Fortune 500 companies.
Check Point continuously monitors Solid's onchain activity for:
Exploit attempts
Abnormal contract behavior
Protocol contagion risks
Irregular activity across vaults, bridges, and integrations
This functions as a DeFi-native firewall: always on, prevention-focused, designed to stop threats before damage occurs.
Vault-level security
Solid's vault system is built on ERC-4626 with additional safety layers:
Asynchronous redemptions to prevent abuse
Withdrawal queues for controlled liquidity release
Automated risk-based rebalancing
Strict permissioning for sensitive operations
Funds are routed only through trusted, diversified protocols. If abnormal risk is detected, operations can be paused automatically.
Withdrawal protection
Withdrawals from yield positions require a secure two-step process, preventing draining attacks and unauthorized automated transfers.
