Sigil for developers

Self-custodial wallets and policy-gated agent signing for B2B apps. Keys are generated and reconstructed inside an iframe or a hardware-attested TEE — never in your servers, never in your bundle.

Quickstart Wallets Agents API reference

Three wallet kinds

Client-side SSS (browser), TEE-custodied (Confidential Space), or ERC-4337 smart accounts on top of either. Same SDK call to sign — Sigil routes.

Gasless onboarding

Opt into a smart account per chain and Sigil sponsors the gas via Pimlico — €10 / wallet / month, no user funding required.

Agents without secret keys

Mint scoped as_live_… session tokens for backend automation, AI workflows, or trading bots. Caps, allowlists, and revocation built in.

Operated by DAC

Bit2Me group — same compliance and security perimeter as a regulated VASP.
