Frequently asked questions
How do embedded wallets work?
Embedded wallets function like traditional non-custodial wallets (e.g., MetaMask), but remove the need to rely on phishable seed phrases, employ familiar authentication methods, and are more deeply embedded into applications for a seamless user experience.
How does 0xKey secure private keys?
0xKey uses AWS Nitro Enclaves, a type of tamper-proof Trusted Execution Environment (TEE), for all sensitive operations. Private keys are never decrypted outside these enclaves, and only you can authorize key usage with your credentials.
Is 0xKey non-custodial?
Yes! 0xKey is fully non-custodial. Users always retain full control of their wallets and private keys.
Which chains do you support?
0xKey's primitive is the cryptographic curve rather than specific cryptocurrencies. We support all EVM-compatible chains, Solana, and more with chain-agnostic signing.
