Clervo vs Blowfish
A different job: verifying a transaction against your declared intent before an automated wallet signs it.
Blowfish provides human-readable transaction previews and warnings integrated into consumer wallets. Clervo targets a narrower problem — an agent or automation wallet that signs untrusted, third-party-generated transactions and needs a machine-actionable decision measured against a declared intent, not a human-facing preview.
| Dimension | Clervo | Blowfish |
|---|---|---|
| Core model | Compares the real simulated effects of a transaction to a caller-declared intent (max spend, allowed recipients, allowed programs). | Scans Solana transactions to return recommended actions, tailored warnings, and human-readable simulation results explaining what the transaction will do. |
| Primary audience | Agent wallets, trading bots, and automation providers signing untrusted, third-party-built transactions. | Wallets integrating a pre-signature preview and warnings for human end users. |
| Decision output | ALLOW / BLOCK / REVIEW plus confidence, reasons, wallet deltas, authority changes, beneficiaries, and an evidence id. Ambiguity defaults to REVIEW. | A list of warnings plus a human-readable simulation of the transaction outcome. |
| Intent awareness | Judges the transaction against a declared intent; outflow to unapproved beneficiaries yields BLOCK or REVIEW even when the protected wallet is a required signer. | Explains what a transaction does and flags danger; the caller supplies no per-request declared intent policy. |
| Evidence | Returns machine-actionable, provenance-linked evidence (simulated slot, state age, effect tree) intended for programmatic policy decisions. | Returns human-readable previews and warnings aimed primarily at end-user display. |
