Built for teams shipping production wallet infrastructure
Four design choices that separate Keychain from generic key management.
Non-custodial by design
Keys are generated, stored, and used inside the enclave. Finance District can't access them — you don't hand over custody, and neither do we.
Built for agent transaction volume
Sub-second signing, built for high-frequency, concurrent agent traffic — architected for autonomous commerce, not retrofitted from human-wallet patterns.
Verifiable by attestation
Your app confirms it's talking to genuine secure hardware before it trusts a signature — verification you can show your own auditors.
Multi-chain from day one
Ethereum, Solana, Sui, Bitcoin, and every major EVM chain. New networks come through configuration, not re-architecture.
Keys generated in hardware. Signed by hardware. Verifiable by anyone.
Hardware-secured keys through one API — four steps from provisioning to a signed transaction, each producing verifiable evidence. From architecture review to your first signed transaction in a day.
01
Provision an enclave
A hardware-isolated secure enclave is provisioned in your environment — no operator shell, no host access, no network egress beyond the attested API.
02
Generate keys inside
Keys are generated inside the enclave and never leave it — not on our servers, not on the host OS, not in your application.
03
Sign with attestation
Your app requests a signature; the enclave signs and returns it with a cryptographic attestation you can verify — not our word for it.
04
Verify on-chain
Every transaction settles on-chain — a permanent, independently verifiable record.
What ships with every integration
A complete key-management surface — from generation through signing to audit.

Wallet apps adding agent capability
Bolt non-custodial agent signing onto your existing wallet without re-architecting custody. Users keep their primary wallet; agents get a scoped signing key.
Custom wallet builders
Build a bespoke wallet on hardened key infrastructure — and skip the long detour through HSM procurement and security review.
Agent platforms
Give every agent on your platform non-custodial signing with one integration. Every agent secured, none of them holding raw keys.
Embedded wallets in fintech
Add wallet functionality to your app without taking custody — or inheriting the regulatory overhead of custodial key management.

Audited, certified, open to inspection
Built on 1st Digital's institutional custody heritage and hardened at every layer — and verified by people outside Finance District.
AWS Nitro Enclaves
Foundation
Runs on the same hardware-isolation platform trusted to protect high-value workloads at cloud scale.
SOC 2
Completed
An independent audit of how we manage security, availability, and confidentiality.
CCSS
In progress
Certification against the CryptoCurrency Security Standard — the benchmark for crypto key management.
Independent pen-tested
Annual
Third-party penetration tests against the enclave, the API, and our operational controls.
Open & auditable
Provable
The implementation is open source — the security model can be inspected, not just taken on trust.
