## 5. Multi-asset support
#
# Many of the RPC calls have added asset type or label arguments, and reveal
# alternative asset information. With no argument all are listed. For example,
# try `getwalletinfo` or `getbalance`. (Notice in the above code our assertions
# have taken forms like {"bitcoin": 100} rather than bare numbers.)
#
# Notice we now see "bitcoin" as an asset. This is the asset label for the hex
# for "bitcoin" which can be discovered using the `dumpassetlabels` RPC. We
# can see more details of each issuance that your wallet knows about with the
# `listissuances` RPC. Initially there is only one asset, "bitcoin", and one
# issuance (the initial issuance).

## 2. Construct a swap transaction in PSET format

# a new asset. We want to do an atomic swap: 2500 BTC for 1000 of
# the new asset.

# currently does not support iteratively creating a transaction. So we must
