For ICS721 it requires these contracts:

• ICS721: the bridge itself
• Incoming Proxy: optional contract for filtering incoming packets
• Outgoing Proxy: optional contract for filtering incoming packets

NOTE: Below scripts use select-chain.sh. For each selected chain there is an .env file like stargaze.env and osmosis.env.

Scripts for setup must be executed in this order:

1. ICS721 without proxies: instantiate-ics721.sh
2. Incoming Proxy: instantiate-incoming-proxy.sh
3. Outgoing Proxy: instantiate-outgoing-proxy.sh

After instantiation:

• update ADDR_ICS721, ADDR_INCOMING_PROXY, ADDR_OUTGOING_PROXY in env file
• Note: ICS721 is instantiated without(!) proxies, proxies are added via migration (velow)

1. ICS721 : migrate-ics721.sh
2. Incoming Proxy: migrate-incoming-proxy.sh
3. Outgoing Proxy: migrate-outgoing-proxy.sh

Usage:

$ ./scripts/whitelist-outgoing-proxy.sh
Usage: ./scripts/whitelist-outgoing-proxy.sh stargaze|osmosis [--add WHITELIST|--remove WHITELIST|--enable true_or_false] --type collection|channel|checksum|fees
Example:
./scripts/whitelist-outgoing-proxy.sh stargaze|osmosis --add channel-1 --type channel
./scripts/whitelist-outgoing-proxy.sh stargaze|osmosis --enable false --type collection

The owner of the outgoing proxy contract can add, remove and enable whitelists for collections, channels, collection checksums, and collection fees.
