Deployed wrappers are identified using custom URIs (Uniform Resource Identifier). For example:
Polywrap URIs have 2 parts:
ens/ for resolving ENS domains, or
ipfs/ for resolving IPFS content.
api.domain.eth for an ENS domain, or
QmaLbZnnnHbcRRo3wNBQ2MhugmBGL9R2YYeBvj6Nk2QumP for an IPFS file/directory.
ipfs/ URI resolution is supported in all Polywrap clients by default. Adding custom URI resolvers is possible. More documentation on how to do this will be released soon.
