Cross Chain Signatures
Chain signatures enable NEAR to sign and execute transactions across multiple blockchains via an MPC (Multi-Party Computation) network. Fortunately, to implement this functionality in your DApp, you won't need to integrate MPC directly, as it's fully operational within Bitte Wallet. Building an EVM transaction is straightforward once you've established a basic connection with the wallet. Redirect to the wallet URL with the evmTx
parameter and the wallet will handle the complexities of generating the EVM signature and sending the transaction.
Note: This functionality currently only works for the NEAR testnet.
Check out NEAR-CA if you would like to implement MPC directly without using a wallet, or to take advantage of its various utilities for interfacing between NEAR and EVM.
