NEAR Adds EdDSA Chain Signatures, Unlocking Cross-Chain Transactions for Solana, Aptos, and More

Distilled summaries of the latest news shaping the future of AI, Web3 and Quantum

April 30, 2025

Details

  • On April 30, NEAR Protocol introduced EdDSA support to its Chain Signatures, enabling seamless transaction signing across Solana, TON, Stellar, Sui, and Aptos.
  • This enhancement builds on NEAR’s chain abstraction strategy by allowing developers to interact with Ed25519-based blockchains from a single, unified interface.
  • EdDSA’s batch verification provides improved efficiency and security over traditional ECDSA, which had previously enabled compatibility with Ethereum and Bitcoin.
  • NEAR’s August 2024 launch of Chain Signatures initially supported only ECDSA-based chains such as Ethereum and Polygon.
  • Leading projects like SWEAT, Atlas Protocol, and Here Wallet are early adopters, leveraging the new capabilities for multi-chain asset management.

Impact

NEAR’s expanded support for EdDSA chain signatures positions it at the forefront of multi-chain interoperability as more blockchains move beyond ECDSA cryptography. By targeting high-performance networks like Solana and Aptos, NEAR aims to draw enterprise and developer interest in highly capable, secure cross-chain infrastructure, fueling momentum in chain abstraction innovation through 2026.
