Narval provides institutional-wallet connectivity for DeFi. Its products let custodians and wallet providers offer curated DeFi access while retaining custody controls and protecting users from blind signing.

Gatekeeper
Project Links
Description
Gatekeeper decodes raw DeFi transaction calldata into structured, human-readable intents and evaluates transactions against protocol-specific whitelist rules. It supports nested, multicall, and batched operations and can be deployed in any environment or run as a sidecar in a zero-trust configuration. Originally designed for custodians and institutional wallets, it helps signing workflows validate transactions from untrusted sources against approved behavior and reduce blind-signing-style attacks.Category: Developer Tooling
Connect
Project Links
Description
Connect enables DApps to use the Narval SDK and API to establish wallet connections and submit transaction requests through integrated custodians or wallet providers. In the provider integration flow, providers implement authentication, token-management, and transaction endpoints, consume Gatekeeper whitelist evaluation reports for approval decisions, and can optionally display DApp catalog metadata.Category: Cross-chain Infrastructure
