Ika Announces EdDSA Signatures, Expanding Native Support to Solana, Zcash, Cardano and More
, the fastest parallel MPC network, today announced a mainnet upgrade that enables, significantly expanding Ika’s native cross-chain coverage to includeThis upgrade extends Ika’s core promise: natively control accounts and assets across chains without bridges, wrapping, custodians, or trusted signers“EdDSA support is a major expansion of what dWallets can control natively,” said, 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.”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:, enabling cross-chain trading, vaults, payments, and automation without wrapped assets.under programmable dWallet policies, unlocking zero-trust custody and interoperability for the most prominent privacy-preserving cryptocurrency.with smart contract-governed access control, enabling organizational treasury workflows and institutional-grade policy enforcement., and enable a coordination layer for policy, composability, and execution logic.Most cross-chain systems rely on bridges, message relays, wrappers, or trusted intermediaries. These approaches introduce risk and limit composability.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.dWallet signing splits authorization into two independent components:operated by Ika’s decentralized network of MPC nodes 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, bringing the benefits of Ika’s architecture to a wider set of chains.This upgrade expands the design space for applications that are only possible with Ika, including:One programmable signing primitive that can operate across EdDSA and non-EdDSA chains, operated with the same SDK and smart contract.Strategies can coordinate multiple ecosystems while keeping assets on their home chains. No wrapping, no “bridged liquidity.”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.Users don’t “rent” their wallet to an app or provider. They co-authorize with the network under strict cryptographic guarantees.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.
