WingRiders Publishes Cardano Implementation for Open Wallet Standard

WingRiders has published two development branches that connect Cardano keys, addresses and transactions with the Open Wallet Standard. Cardano founder Charles Hoskinson highlighted the work in a video on wallet security and agentic custody.

Cardano Modules Add Keys and Transaction Signing

The public WingRiders fork includes the cardano-public and cardano-multiple-rpc-providers-public branches.

The implementation uses Cardano’s CIP-1852 derivation standard for payment and stake keys, generates Shelley Bech32 addresses and includes configurations for mainnet, Preprod and Preview.

Its signer supports messages and prepared transactions involving ADA and Cardano native assets. A network layer can retrieve transaction data from multiple RPC providers, allowing the OWS policy engine to inspect inputs and transaction effects before signing.

WingRiders operates a Cardano decentralized exchange where users can swap tokens, provide liquidity and access DeFi products. The OWS implementation extends its development into wallet infrastructure for automated applications.

OWS Controls Wallet Access for AI Agents

The Open Wallet Standard provides a common interface for applications, development tools and AI agents that need blockchain wallet access.

Private keys remain encrypted on the user’s device. Agents connect through scoped credentials, while a policy engine checks rules such as permitted networks, spending limits and approved destinations before authorizing a signature.

OWS can be accessed through command-line tools, SDKs, MCP and REST interfaces. The Cardano modules apply this structure to ADA and native assets without giving an AI agent direct access to the private key.

Cardano Support Awaits an Upstream Release

Cardano is not currently listed among the supported networks in the main OWS repository, and the WingRiders modules are absent from its standard installation packages.

Developers can inspect, test and build the Cardano implementation from the public fork. Wider availability requires upstream review, a merge into the main repository and a new package release.

Until then, Cardano support is publicly testable through WingRiders’ development branches, but it will not be included when users install OWS through its standard distribution channels.
