Zug, Switzerland, December 4th, 2025, Chainwire 
<a href="https://ika.xyz/" rel="noopener noreferrer nofollow">Ika</a>, the fastest parallel MPC network, today announced a mainnet upgrade that enables EdDSA signatures directly from dWallets, significantly expanding Ika’s native cross-chain coverage to include Solana, Zcash, Cardano, Stellar, Near, and other EdDSA-based ecosystems.
This upgrade extends Ika’s core promise: natively control accounts and assets across chains without bridges, wrapping, custodians, or trusted signers, now across a broader set of networks where EdDSA is the standard.
<blockquote>
 “EdDSA support is a major expansion of what dWallets can control natively,” said Omer Sadika, Co-Founder of Ika. “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.”
</blockquote>
What This Upgrade Enables
Until now, Ika’s dWallets provided zero-trust signing and programmable control for major ecosystems, including Bitcoin and EVM-compatible networks with ECDSA signatures. With EdDSA enabled at the dWallet signing layer, builders can now create applications that:
<ul>
 <li>Control Solana accounts natively, enabling cross-chain trading, vaults, payments, and automation without wrapped assets.</li>
 <li>Coordinate Zcash-native actions under programmable dWallet policies, unlocking zero-trust custody and interoperability for the most prominent privacy-preserving cryptocurrency.</li>
 <li>Manage Cardano, Stellar, Near accounts with smart contract-governed access control, enabling organizational treasury workflows and institutional-grade policy enforcement.</li>
</ul>
In short: dWallets become natively multi-ecosystem signers, and enable a coordination layer for policy, composability, and execution logic.
Native Cross-Chain Control
Most cross-chain systems rely on bridges, message relays, wrappers, or trusted intermediaries. These approaches introduce risk (custody, exploits, governance capture) and limit composability.
Ika’s model is different: no bridging of assets is required. Instead, Ika enables native signing via dWallets, where transaction authorization is always enforced under zero-trust assumptions.
With EdDSA enabled, the same 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.
How EdDSA Works in Ika’s Zero-Trust Model
Ika’s security model is built on its 2PC-MPC cryptographic scheme.
dWallet signing splits authorization into two independent components:
<ul>
 <li>User share: held and authorized locally by the user</li>
 <li>Network share: operated by Ika’s decentralized network of MPC nodes</li>
</ul>
Both are required to produce a valid signature, and the full private key is never reconstructed. With this mainnet upgrade, that same model now supports EdDSA signing, bringing the benefits of Ika’s architecture (zero-trust, decentralization, scalability, sub-second performance, and programmable policy enforcement) to a wider set of chains.
Why It Matters for Builders and the Ecosystem
This upgrade expands the design space for applications that are only possible with Ika, including:
Universal accounts across ecosystems
One programmable signing primitive that can operate across EdDSA and non-EdDSA chains, operated with the same SDK and smart contract.
Cross-chain DeFi with native assets
Strategies can coordinate multiple ecosystems while keeping assets on their home chains. No wrapping, no “bridged liquidity.”
Programmable custody and access control
Rules are enforced at the signing layer: multi-party approvals, intent constraints, spending limits, automated risk controls, and organizational policy, secured cryptographically rather than contract-side permissions alone.
Chain abstraction that’s actually zero-trust
Users don’t “rent” their wallet to an app or provider. They co-authorize with the network under strict cryptographic guarantees.
Availability
The EdDSA-enabled signing upgrade is live on Ika mainnet, and supports dWallet-based signing for Solana, Zcash, Cardano, Stellar, Near, and additional EdDSA-compatible chains.
