Non Fungible Token (NFTs)

Paano lumikha ng isang NFT

Upang lumikha ng isang NFT kailangan mong:

I-upload ang larawan sa IPFS tulad ng Arweave
I-upload ang json metadata sa IPFS tulad ng Arweave
Tumawag sa metaplex para gumawa ng account para sa NFT

I-upload sa Arweave

Tandaan

Hindi ka makakagawa ng NFT na may ibang tagalikha kaysa sa iyong wallet. Kung magkakaroon ka ng mga isyu sa creator, tiyaking inilista ka ng iyong metadata bilang lumikha.

Paano makakuha ng NFT Metadata

Ang mga Metaplex NFT ay may metadata na nakaimbak sa Arweave. Sa pagkakasunud-sunod para makuha ang Arweave metadata, dapat mong makuha ang Metaplex PDA at i-decode ang data ng account.

Paano makuha ang may-ari ng isang NFT

Kung mayroon kang mint key ng isang NFT, mahahanap mo ang kasalukuyang may-ari nito sa pamamagitan ng sneak-peeking sa pinakamalaking token account para sa mint key na iyon.

Tandaan na ang mga NFT ay may supply na 1, at sila ay hindi mahahati, ibig sabihin, isang token account lang ang hahawak ng token na iyon kahit saan punto sa oras, habang ang lahat ng iba pang mga token account para sa mint key na iyon may balanseng 0.

Kapag natukoy na ang pinakamalaking token account, maaari nating makuha ang may-ari nito.

Paano makakuha ng NFT Mint Address

Kung alam mo ang pampublikong key ng Candy Machine, maaari mong makuha ang listahan ng lahat ng NFT mint address na nabuo mula sa Candy Machine na iyon gamit ang sumusunod na code. Tandaan na maaari nating gamitin ang sumusunod na memcmp na filter dahil, sa v1, ang unang gumawa ay palaging ang address ng Candy Machine.

Kung gumagamit ka ng Candy Machine v2, kakailanganin mo munang i-access ang "Candy Machine Creator" address nito na isang simpleng PDA gamit ang candy_machine at ang Candy Machine v2 address bilang mga buto. Kapag mayroon ka na ng address ng tagalikha, magagamit mo ito sa parehong paraan na ginamit namin para sa v1.

Paano makukuha ang lahat ng NFT mula sa isang wallet?

Kapag nakuha ang lahat ng NFT mula sa isang wallet, kakailanganin mong makuha ang lahat ng token account at pagkatapos ay i-parse kung alin ang mga NFT. Magagawa ang lahat ng ito gamit ang findDataByOwneropen in new window mula sa Metaplex JS library.

Candy Machine v2

Sinusuportahan na ngayon ng Metaplex JS SDK ang paggawa at pag-update ng Candy Machine v2 sa pamamagitan ng code. Nagbibigay-daan ito sa mga developer na makipag-ugnayan sa programang Candy Machine v2 at lumikha, mag-update, at magtanggal ng mga Candy Machine pati na rin ang mga mint na NFT mula sa kanila.
