Stablerail as a Turnkey alternative
Turnkey gives developers secure, programmable key management inside verifiable secure enclaves, with policies expressed in code and signing exposed through an API. Stablerail solves the layer above: the account a finance team actually operates, where the policy is an approval workflow an admin configures and the output is a paid vendor, a funded card and an audit trail.
Side by side
| Dimension | Stablerail | Turnkey |
|---|---|---|
| Primary buyer | CFO or finance lead at an operating company | Engineering teams building wallet, signing or fintech features |
| Shape of product | A business account with a finance UI | Key management and signing APIs with a policy engine |
| Custody | Self-custodial MPC with quorum-protected key export; Stablerail cannot sign alone | Non-custodial key infrastructure held in secure enclaves; your product defines who can sign |
| Networks | Ethereum, Arbitrum, Base, Optimism, Polygon, BNB Chain, Solana, Tron, Bitcoin, Litecoin, Bitcoin Cash and XRP from one account | Chain-agnostic signing across common curves; the chain integration is written by you |
| Policy model | Approval limits, allowlists, self-approval limits and signing quorum set by an admin in the UI; changing policy itself needs Admin plus quorum | Policies written, reviewed and deployed as code by engineers |
| Counterparties | Counterparty register with legal name, accepted network, address history and screening per record | Implemented by your application |
| Screening | Sanctions and wallet-risk checks before release plus ongoing monitoring, stored as evidence against the payment | Not included; you integrate an analytics vendor and enforce it yourself |
| Payouts | Batch vendor, contractor and payroll runs built in | Sign-and-broadcast APIs; batching is your code |
| Cards | Stablecoin-funded corporate cards with limits, freeze and transaction feed | Not a card programme |
| Fiat rails | SEPA, SEPA Instant, ACH, SWIFT, Faster Payments and virtual IBANs via regulated partners | Not included |
| Invoicing | Payment requests, invoices and reconciliation | Not included |
| Gas | Fees sponsored where supported on Tron, EVM and Solana | Fee funding is your application's problem |
| Evidence and close | Audit log, exportable evidence pack per transaction and auditor-ready records | Signing activity logs via API |
| Recovery | Documented account recovery and compromise response under quorum protection | Designed and operated by you |
| Engineering required | None to operate the account | An integration project, then ongoing ownership |
| Support | Named account manager and operational support | Developer support and documentation |

Choose Stablerail if
- You need a working treasury account, not a signing primitive to build on.
- Your controls need to be readable by an auditor, not only by an engineer.
- You pay contractors, vendors and payroll in USDC or USDT on a schedule.
- You hold USDT on Tron or balances on Solana and Bitcoin alongside EVM chains.
- You want cards and fiat off-ramps funded from the same balance.
Choose Turnkey if
- You are building a wallet, exchange or fintech product that signs on behalf of end users.
- You want policy-as-code and full control over signing infrastructure and its verifiability.
- You need signing at machine scale rather than human approvals.
- You have engineers who will own that infrastructure long term.
Frequently asked questions
Is Stablerail a Turnkey alternative?
For a company treasury, yes. Turnkey is infrastructure for developers embedding signing into their own product. If your goal is to run your own company's stablecoin money movement with controls and evidence, Stablerail delivers that as a product instead of a build.
Is Stablerail non-custodial like Turnkey?
Stablerail is self-custodial. Keys are split using MPC and the organisation holds a share, so Stablerail cannot sign alone and the organisation can export keys under quorum. Turnkey's model is enclave-based key management your own application drives.
How do controls differ?
Turnkey expresses policy as code deployed by engineers. Stablerail expresses it as organisation-level approval limits, allowlists and a signing quorum that an admin configures — and changing a policy itself requires Admin plus quorum approval, with the change recorded in the audit log.
Does Turnkey screen payments or provide fiat rails?
No. It signs what your policy permits. Sanctions screening, wallet-risk monitoring, corporate cards and SEPA, ACH, SWIFT or Faster Payments rails are separate problems you would assemble yourself; Stablerail includes them in the account.
Can we use both?
Yes. Some teams run product-side signing on infrastructure like Turnkey and keep corporate treasury separate in Stablerail, so company funds are not governed by product code paths.
