Example 1 with JsonRpcMethod

use of com.github.arteam.simplejsonrpc.core.annotation.JsonRpcMethod in project web3signer by ConsenSys.

the class FcJsonRpc method filecoinWalletSign.

        }
    }
}

Example 2 with JsonRpcMethod

use of com.github.arteam.simplejsonrpc.core.annotation.JsonRpcMethod in project web3signer by ConsenSys.

the class FcJsonRpc method filecoinWalletVerify.

        case SECP256K1:
            checkArgument(filecoinSignature.getType() == SECP_VALUE, "Invalid signature type");
            return FilecoinVerify.verify(address, dataToVerify, SecpArtifactSignature.fromBytes(signature));
        case BLS:
