This flow chart illustrates how NEAR Protocol’s Chain Signatures enable seamless cross-chain interactions. A user initiates a transaction from their @near-protocol  account, which cryptographically signs the request using EdDSA. The signed transaction is verified by validators and relayers, then executed on the destination chain (e.g., Solana, Ethereum, TON). This design abstracts away blockchain-specific complexity, empowering users to control assets across multiple chains through a single NEAR identity—paving the way for chain-agnostic dApps and true multichain usability.

"NEAR’s Chain Signatures are a game-changer—finally, multichain interaction feels native. One identity, seamless access across ecosystems like Solana, Ethereum, and TON. This is what real interoperability looks like."
