Turnkey Alternative: A Governance Control Plane, Not Just Signing
Turnkey is enterprise-grade key infrastructure: a policy engine and signing running inside a secure enclave. Agentspay is the alternative when you want a rail-neutral governance and audit control plane above the keys, not another signing layer to build on.

In short
A Turnkey alternative is a tool that provides agent-spend governance rather than low-level key custody. Turnkey is wallet-as-a-service infrastructure whose policy engine and signing run inside a secure enclave (Intel SGX) with attestation on every request. Agentspay is a rail-neutral, fiat-card-first control plane: it evaluates every agent request against policy before money moves, pauses above a threshold for human approval, issues scoped virtual cards, and writes an immutable audit trail attributed to the agent and its owner. Use Turnkey when you want verifiable key custody to build your own agent layer; use Agentspay when you want governance and audit as the product, and it can run above Turnkey.
Where Turnkey fits
Turnkey is a serious piece of security engineering. It generates and uses private keys exclusively inside hardware-backed Trusted Execution Environments (Intel SGX), runs its policy engine inside the same enclave so every signing request is checked before a signature is produced, and offers sub-100ms signing with cryptographic attestation and delegated agent access. If you need verifiable key custody and want to build your own agent layer on signing you fully control, Turnkey is one of the strongest options available.
Where Agentspay fits
Turnkey secures the key and enforces signing policy inside an enclave. That answers "can this key sign this transaction." Agentspay answers a different question: "should this agent spend this money, on which rail, with whose approval, and how is it recorded for finance." Agentspay is rail-neutral and fiat-card-first rather than crypto-only, and ships governance as the finished product: hard spend limits, human-in-the-loop approvals routed to Slack, email or a webhook, scoped single-use virtual cards issued by API, instant revocation, and an immutable, agent-attributed audit trail. As with other signing infrastructure, Agentspay can sit above Turnkey; the choice is whether you assemble the governance layer yourself or adopt it whole.
Side by side
Agentspay compared with Turnkey
An honest look at how each one approaches agent payments.
| Dimension | Agentspay | Turnkey |
|---|---|---|
| Layer | Higher-level control plane: policy, approvals, audit as the product. | Low-level key infrastructure and enclave-based signing you build on. |
| Rails | Rail-neutral and fiat-card-first, crypto optional. | Crypto-native, multichain on-chain signing. |
| Spend policy | Policy engine checks amount, counterparty and velocity before any rail moves money. | Policy engine enforced inside the enclave at crypto signing time. |
| Key security | Relies on your issuer and rails; not a key-custody product. | A genuine strength: keys generated and used only inside hardware TEEs (Intel SGX) with attestation. |
| Human approval | Threshold-based approval gates routed to Slack, email or a webhook. | Delegated access and policy rules you configure in the signing flow. |
| Virtual cards | Scoped, single-use, time-bound fiat virtual cards issued by API. | No fiat card issuing; focus is crypto key management and signing. |
| Audit trail | Immutable, agent-attributed record a finance team can sign off on. | On-chain history plus signing logs; not a finance-grade attributed trail. |
