A technical comparison of OWS, Turnkey, and Dynamic — three signing architectures for autonomous trading agents, treasury management, and multi-chain operations.
| Capability | OWS | Turnkey | Dynamic |
|---|---|---|---|

Yes — turnkey (tkcli) |
None |
| MCP server | Native, built-in | None | None |
| REST API | Localhost only | Remote (TEE-backed) | Remote (TEE-backed) |
| Node.js / TS SDK | Yes — Rust FFI | Yes — full suite | Yes — React, vanilla, headless |

| x402 protocol | Yes | No | Yes |
| Dimension | OWS | Turnkey | Dynamic |
|---|---|---|---|
| Cryptographic model | Single key BIP-39 mnemonic |
Single key in TEE Enclave-isolated |
TSS-MPC distributed Key never exists |
| Key isolation | Software subprocess (mlock + zeroize) |
AWS Nitro Enclave (hardware boundary) |
MPC shares across TEEs (hardware + cryptographic) |
| Signing speed | ~1 ms | 50–100 ms | sub-second |
| Co-signing / multi-party | None Single signer only |
Hierarchical Owner → delegate approval |
Native t-of-n 2/2, 2/3, 3/5 thresholds |
| Key resharing | N/A | N/A | Yes — rotate shards, same address |
| Key export | Full — your mnemonic | HPKE encrypted export | User-initiated export |
| Audit / compliance | Append-only local JSONL | SOC 2, full activity logs | SOC 2 Type II, yearly audits |
| Feature | OWS | Turnkey | Dynamic |
|---|---|---|---|
| EVM chains | Yes — secp256k1 | Yes — secp256k1 | Yes — DKLs19 ECDSA |
| Solana | Yes — Ed25519 | Yes | Yes — FROST EdDSA |
| Bitcoin | Yes — BIP-84 | Limited | Yes — FROST BIP-340 |
| Cosmos / TON / Tron | All three | Partial | EVM + SVM focus |
| ERC-4337 smart accounts | None | Native | Via ZeroDev / Biconomy |
| EIP-7702 (Type 4 tx) | None | Native | Native |
| Gas sponsorship | None | Paymaster native | Automated |
| Addressing standard | CAIP-2 / CAIP-10 | Chain-native | Chain-native |
| Capability | OWS | Turnkey | Dynamic |
|---|---|---|---|
| Policy model | Declarative rules + executable subprocess |
TEE-native policies + async human approval |
Granular API-level policies + m-of-n quorum |
| Chain restrictions | Yes | Yes | Yes |
| Spending limits | Via custom executable | Native | Native |
| Contract allowlists | Via custom executable | Native | Native |
| Human approval gate | 5s timeout kills it | Native — passkey/webhook | Quorum-based |
| Time-bound access | expires_at rule | Session expiry | Authorization keys |
| Tx simulation gate | Custom executable | Built-in | External integration |
| Factor | OWS | Turnkey | Dynamic |
|---|---|---|---|
| Deployment model | Self-hosted, local-first | Managed cloud (TEE) | Managed cloud (TEE) |
| KYB / KYC required | None | None | None |
| Cost | Free forever | Per-signature | Per-MAU + free tier |
| Vendor dependency | None — fully local | Turnkey infra required | Dynamic/Fireblocks infra |
| Backers / ecosystem | MoonPay, PayPal, Circle, ETH/SOL/TON Foundations |
Independent, VC-funded (Sequoia backing) |
Fireblocks (acquired 2025), Stripe, Magic Eden, Kraken |
| Open source | Fully open — MIT | CLI open, service closed | SSS lib open, service closed |
| Server wallets (agentic) | Via API token scoping | Sub-org + session keys | Dedicated server wallet API |
v0.3.x — launched March 23, 2026. No security audit yet. Software-only key isolation (no TEE). 5-second policy timeout blocks human approval flows. No native AA or gas sponsorship.
Single key in enclave — not MPC, not threshold. No native m-of-n quorum. Co-signing is hierarchical (owner → delegates), not peer multi-party. Per-signature cost scales with volume.
Server share lives on Dynamic/Fireblocks infra — vendor dependency for signing. No CLI, no MCP server, no Python SDK. Acquired by Fireblocks — long-term roadmap may shift to enterprise. TSS-MPC still in beta for some features.
Each tier handles a different risk profile. Transactions are routed by the Openclaw orchestration layer based on value, destination, and policy requirements.
Bot-level arena wallets. Small balances, autonomous DEX routing, MCP-native. Each bot gets a scoped API token with contract allowlists and chain restrictions. Signs in microseconds.
User deposit wallets, withdrawal approval, hot-wallet ops requiring personal sign-off. Passkey-gated on your phone. Native ERC-4337 + EIP-7702 for gas sponsorship and batching.
Treasury management with true MPC. Private key never exists. Threshold signing (2/3, 3/5) for high-value multi-chain ops. Server wallets for automated rebalancing with policy guardrails.
