Algorand - NFTs Mint and Transfer to Recipient

NFTs over Algorand work a bit differently than other EVM (like Ethereum) chains.

Algorand charges users for storing NFTs on their addresses and an Algorand blockchain address by default does not receive NFTs unless the owner of the address explicitly agrees to receive an NFT.

Parameters

NFT Transfer Example - Algorand

An NFT that you mint on Algorand is automatically transferred to your blockchain address. After the NFT is minted, you have to transfer it to the recipient's address.

The recipient has to agree in advance to receive your NFT (by default, Algorand charges users for storing NFTs on their addresses which, by default, does not receive NFTs unless agreed).

Step_1 - The recipient agrees with the NFT reception

The recipient agrees to receive the NFT. Recipient enables accepting assets on an Algorand address using the mintNftExpressAlgorand schema:

Request Example:

curl -i -X POST \
  https://api.tatum.io/v3/algorand/asset/receive \
  -H 'Content-Type: application/json' \
  -H 'x-api-key: {API_KEY}' \
  -d '{
    "assetId": "116363571", //The NFT the recipient must agree to recieve.
    "fromPrivateKey": "####"
  }'

Step_2 - The sender sends the NFT to the recipient

You transfer the NFT to the recipient's address using the transferNftAlgoExpress schema:

Request Example:

curl -i -X POST \
  https://api.tatum.io/v3/nft/transaction \
  -H 'Content-Type: application/json' \
  -H 'x-api-key: {API_KEY}' \
  -d '{
    "chain": "ALGO",
    "to": "TMETT6BXL3QUH7AH5TS6IONU7LVTLKIGG54CFCNPMQXWGRIZFIESZBYWP4",
    "contractAddress": "100000"
  }'
