이 예제는 다음을 보여줍니다:
새로운 Non-fungible Tokens (NFTs) 발행하기.
기존 NFTs의 목록을 얻는 방법.
NFT를 삭제(소각)하는 방법.
브라우저에서 3.mint-nfts.html을 엽니다.
테스트 계정을 가져옵니다.
계정 seed가 있는 경우
Seeds 필드에 계정 seed를 붙여넣습니다.
Get Accounts from Seeds를 클릭합니다
계정 seed가 없는 경우
Get New Standby Account를 클릭합니다.
Get New Operational Account를 클릭합니다.
non-fungible token 객체를 발행하려면:
Token URL을 입력합니다. 이는 NFT 객체와 연결된 데이터 또는 메타데이터를 가리키는 URI입니다. 자신의 URI가 없다면 제공된 샘플 URI를 사용할 수 있습니다.
Transfer Fee를 입력합니다. 이는 NFT의 향후 판매 수익의 일정 비율이 원래의 창작자에게 반환될 것임을 의미합니다. 이는 0-50000 사이의 값으로, 전송 비율을 0.000%에서 50.000%까지 0.001%의 증분으로 허용합니다. NFT가 전송 가능하도록 Flags 필드를 설정하지 않는다면, 이 필드를 0으로 설정합니다.
Mint NFT를 클릭합니다.
Get NFTs를 클릭하여 계정이 소유한 NFTs의 목록을 얻습니다.
NFT의 현재 소유자는 언제나 NFT 객체를 파괴(또는 소각)할 수 있습니다.
NFT를 영구히 파괴하는 방법:
Token ID를 입력합니다.
Burn NFT를 클릭합니다.
