The crypto world is buzzing with the latest announcement from Ika, the fastest parallel MPC network. On December 4th, 2025, the company revealed a mainnet upgrade enabling EdDSA signatures for dWallets, significantly transforming the ability to natively interact across chains such as Solana, Zcash, Cardano, Stellar, and Near, among others. This pivotal improvement reinforces Ika’s dedication to providing native cross-chain control without relying on bridges, wrapping, or trusted intermediaries.
Welcome to an Era of Zero-Trust Cross-Chain Control
With the EdDSA-enabled mainnet update, developers can now harness the power of zero-trust, programmable signing for some of the biggest chains in the ecosystem. According to Ika co-founder Omer Sadika, “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.”
What Does This Upgrade Unlock?
Ika’s dWallets previously supported Bitcoin and EVM-compatible networks using ECDSA signatures. This latest development now extends their zero-trust signing service to EdDSA-supported ecosystems. Builders and developers can fully utilize dWallets across chains, enabling:
- Seamless cross-chain DeFi with native asset management.
- Programmable custody with multi-party and automated controls.
- Universal account management across ecosystems.
For instance, applications no longer need alternative solutions like bridges or custodians, which introduce risks and governance challenges. Ika ensures secure coordination of policies and execution, all controlled natively via EdDSA-enabled dWallets.
How Ika’s Zero-Trust Model Enhances Security
The foundation of Ika’s upgrade lies in its 2PC-MPC cryptographic framework, guaranteeing that private keys are never fully reconstructed. This robust model emphasizes:
- Decentralization: Transaction authorization relies on a zero-trust design.
- Security: Split authorization prevents unauthorized access or reconstruction.
- Scalability: Sub-second latency ensures unmatched performance.
By incorporating EdDSA signatures, Ika now extends these features to blockchains where this cryptographic method dominates, immediately broadening the scope for interoperability and secure transactions.
Applications for End Users and Developers
For builders, this upgrade represents an opportunity to break through previous limitations in multi-chain integration. Whether it’s DeFi platforms that require native, cross-chain liquidity or organizations needing programmable asset control, Ika’s enhanced dWallet technology is the key to unlocking innovative solutions. End-users also benefit with seamless interoperability and unmatched control of their digital assets.
