안녕하세요.  
다름이 아니라 개발 중인 코드 중 일부가 baobab에서는 동작하고, cypress에서는 동작하지 않아서 질문 드립니다.

코드와 에러 첨부드립니다.

+@ gasPrice에 변경관련 메일을 받은게 기억나서 750ston을 명시하면, Error: Returned error: invalid unit price 라는 에러가 나고요.

```nohighlight
const callobj = this.contract.methods.safeTransfer(to, value)
        const gas = await callobj.estimateGas({from: this.sender.address}); // gas 조회
        console.log('[*] estimated gas:', gas)

        const result = await callobj.send({
            from: this.sender.address,
            gas
        }); // tx send

```

에러는 아래와 같습니다.

```auto
     Error: out of gas

아 호출방법을 바꾸니까 cypress에서도 되네요

baobab에서는 되던게 cypress에선 안되서 혼란스러웠습니다.

```nohighlight
        const callobj = this.contract.methods.safeTransfer(to, value)
        const gas = await callobj.estimateGas({from: this.sender.address}); // gas 조회
        console.log('[*] estimated gas:', gas)

        // const result = await callobj.send({
        // from: this.sender.address,
        // gas
        // }); // tx send

        const result = await this.caver.klay.sendTransaction({
            from: this.sender.address,
            to:this.tokenAddr,
            data: callobj.encodeABI(),
            gas,
        })

```

안녕하세요?  
혹시 어떻게 성공하셨는지 자세히 좀 알 수 있을까요?  
caver.klay.sendTransaction 이 함수를 사용하면  
지원하지 않는 메소드라고 뜨는데…  
클레이튼 cypress에서 어떤 식으로 트랜잭션을 발생하는지 그러니까,  
유저가 사이트에서 민팅 버튼을 누르면  
결제창이 열려서 결제를 하고  
NFT가 발송되는지를 모르겠습니다.

밤 늦게라도 좋으니 부디 연락주시길 부탁드립니다.  
감사합니다.
