# Tezos chain considerations

1. In the `abi` parameter of the `NFT_INFO` only the function name is needed without the list of params
2. The `customMintParams` parameter will hold the list of arguments the function in the `abi` gets and translate them to their michelson representation
3. For ex:

```javascript
abi: "buy_nft"
customMintParams: {
    wallet_address: <WALLET_ADDRESS>,
    nft_uri: <NFT_URI>
}
```
