The data field in cosmwasm_std::Response is underused. We should use it more! Here's why.

Often we want to program contracts that do this:

call another contract
after the call is completed, handle the response and do some extra actions

For example,

swap some token A to token B at Astroport

CW-SDK's bank contract will manage both fungible and nonfungible tokens.

Each fungible token is identified by a denom
Each nonfungible token is identified by a tuple (denom, sequence) where sequence is a u64; the 1st token in the collection gets a sequence of 0, the 2nd gets 1, so on

An NFT collection cannot share the same denom with a fungible token.

struct Coin {
    pub denom:  String,

Configure gpg signing (importing an existing private key):

git config --global user.name 'your-name'
git config --global user.email 'your-email'
git config --global user.signingkey 'your-gpg-pubkey'
git config --global commit.gpgsign true
git config --global --list

sudo apt install gpg
