Security
Your keys never leave the hardware.
Phantom stores keys in your browser. Exchanges hold them on their servers. Sigcore locks them inside tamper-proof hardware that nobody can access, and makes them available on every device. Want to export your seed? You can. It's your wallet policy to decide.

Hardware-encrypted
Keys live inside AMD SEV-SNP secure enclaves with hardware-level encryption that can't be bypassed, even with physical access to the server.
Zero-access architecture
Sigcore engineers, cloud providers and infrastructure operators cannot see or access your keys. The hardware enforces this, not just policy.
Export on your terms
By default, your keys are locked inside hardware. If you want full self-custody, you can enable seed phrase export through your wallet policy. Your choice, your control.
Cross-device without compromise
Your keys stay in hardware. You access them from any device through authenticated sessions. No seed phrase sync, no extension migration.
Verifiable signing
Every signing operation produces a cryptographic attestation proving it ran inside authentic AMD SEV-SNP hardware. Trust math, not us.
Spending controls
Set daily limits, approve large transactions manually, and allowlist destination addresses. Your rules, enforced at the hardware level.

How is it free?
Businesses pay, you don't
Companies that build wallets into their own products pay for the same signing platform. That covers your wallet.
Only the network fee
When you send, you pay the blockchain's own transaction fee and nothing on top. We don't add a markup.
No ads, no data sales
Your activity isn't a product. We don't run ads and we don't sell what you do with your wallet.
