Today, Ika, the fastest parallel MPC network, announced the expansion of its native cross-chain coverage to include Solana, Zcash, Cardano, Stellar, Near, and other EdDSA-based ecosystems.
This is made possible with a mainnet upgrade that enables EdDSA signatures directly from dWallets. The upgrade brings to fruition Ika’s promise to enable the ability to natively control accounts and assets across chains without bridges, wrapping, custodians, or trusted signers.
Commenting, Omer Sadika, Co-Founder of Ika, said:
“EdDSA support is a major expansion of what dWallets can control natively. It brings zero-trust, programmable signing to some of the most important ecosystems in crypto, so developers can orchestrate real cross-chain actions with real native assets, governed by Ika dWallet technology.”
 
Ika network has only been able to provide zero-trust signing and programmable control for major ecosystems, including Bitcoin and EVM-compatible networks with ECDSA signatures. Going forward with EdDSA at the dWallet signing layer, it is now possible to create applications that control Solana accounts natively, enabling cross-chain trading, vaults, payments, and automation without wrapped assets.
Builders can also build applications that coordinate Zcash-native actions under programmable dWallet policies, making zero-trust custody and interoperability for the most prominent privacy-preserving cryptocurrency possible, as well as applications that manage Cardano, Stellar, and Near accounts with smart contract-governed access control, enabling organizational treasury workflows and institutional-grade policy enforcement.
Under this design, dWallets become natively multi-ecosystem signers and enable a coordination layer for policy, composability, and execution logic. Another major achievement is native cross-chain control, which ensures security by eliminating the need to bridge assets, which hitherto exposed the system to exploits, governance capture, and other vulnerabilities.
Ika’s model enables native signing via dWallets, where transaction authorization is consistently enforced under zero-trust assumptions. The architecture now extends to chains where ECDSA is not supported, and EdDSA has been adopted instead, dramatically expanding the surface area of what Ika dWallets can safely and directly orchestrate.
The security model is built on its 2PC-MPC cryptographic scheme, which splits authorization into two independent components: the user share, held and authorized locally by the user, and the network share, managed by Ika’s decentralized network of MPC nodes.
As both are required to produce a valid signature, the full private key is never reconstructed. That same model now supports EdDSA signing with this upgrade, bringing the benefits of Ika’s zero-trust, decentralized, scalable, sub-second performance, and programmable policy enforcement architecture to more chains.
With the upgrade, builders can now access the design space for applications that are only possible with Ika, including universal accounts across ecosystems, cross-chain DeFi with native assets, programmable custody and access control, and chain abstraction that’s actually zero-trust. Developers can begin integrating EdDSA-enabled dWallet workflows immediately through Ika’s developer resources.
