This is a repo containing bifrost contract set that needs to be deployed in tezos to connect it to cosmos ecosystem using a pegzone called bifrost zone
step1 : Install tezos-client
find tezos-client installation guide here
step2 : Clone and setup the repo
$ git clone github.com/sap200/bifrost_contract_set
$ cd bifrost_contract_set
$ chmod +x setup.bash
$ ./setup.bash
Navigate to commands directory in bifrost_contract_set
$ cd commands
$ ls
fa12send.bash fetch_bigmaps.bash fetch_storage.bash send_to_cosmos.bash
gedit send_to_cosmos.bash
#!/bin/bash
tezos-client transfer 100 from alice to "$(cat ../contract_addr/bifrost.txt)" --fee 1 --arg "(Left (Right (Pair \"mars\" (Pair \"cosmos1j5pz7cp5w6wr65z47azefzygcevqssrguccc88\" \"tezos_chain\"))))" --burn-cap 0.05475
Edit sender and amount if you want to and the cosmos receiver address, Tx fails if cosmos receiver is wrong. save file
$ chmod +x send_to_cosmos.bash
$ ./send_to_cosmos.bash
usage ./send_to_cosmos [cosmos_receiver] [amount] [tezos_sender]
$ ./send_to_cosmos cosmos1j5pz7cp5w6wr65z47azefzygcevqssrguccc88 100 alice
$ gedit fa12send.bash
#!/bin/bash
#echo "minting.."
tezos-client transfer 0 from alice to "$(cat ../contract_addr/fa12.txt)" --fee 1 --arg "(Right (Left (Left (Pair \"$(cat ../keys/bob_pub.txt)\" 12))))" --burn-cap 0.0185
echo "..send_to_cosmos"
tezos-client -w 15 transfer 0 from bob to "$(cat ../contract_addr/fa12.txt)" --fee 1 --arg "(Right (Left (Right (Left (Pair (Pair 5 \"cosmos_chain\") (Pair \"cosmos1j5pz7cp5w6wr65z47azefzygcevqssrguccc88\" (Pair \"tezos_chain\" \"$(cat ../keys/bob_pub.txt)\")))))))" --burn-cap 0.04525
# echo "approve alice"
# tezos-client transfer 0 from bob to "$(cat ./contract_addr/fa12.txt)" --fee 1 --arg "(Left (Left (Left (Pair \"$(cat ./keys/alice_pub.txt)\" 5))))" --burn-cap 0.00775
step a is minting token since you originate contract there's
tezos-client transfer 0 from alice to "$(cat ../contract_addr/fa12.txt)" --fee 1 --arg "(Right (Left (Left (Pair \"$(cat <<Your tezos address file path>>)\" <<amount>>))))" --burn-cap 0.0185
echo "..send_to_cosmos"
step b is sending it
tezos-client -w 15 transfer 0 from bob to "$(cat ../contract_addr/fa12.txt)" --fee 1 --arg "(Right (Left (Right (Left (Pair (Pair <<Amount to send>> \"cosmos_chain\") (Pair \"<<cosmos_address>>\" (Pair \"tezos_chain\" \"$(cat <<path to your tezos address file>>)\")))))))" --burn-cap 0.04525
Note: Instead of path you can directly provide your tezos address
tezos-client -w 15 transfer 0 from bob to "$(cat ../contract_addr/fa12.txt)" --fee 1 --arg "(Right (Left (Right (Left (Pair (Pair <<Amount to send>> \"cosmos_chain\") (Pair \"<<cosmos_address>>\" (Pair \"tezos_chain\" \"<<tezos_address>>\")))))))" --burn-cap 0.04525
After editing
$ chmod +x fa12send.bash
$ ./fa12send.bash
or in new version
$ ./fa12send.bash [cosmos_receiver]
$ ./fa12send.bash cosmos1j5pz7cp5w6wr65z47azefzygcevqssrguccc88
$ chmod +x fetch_storage
$ ./fetch_storage

Bigmaps are used to store balance in FA12, locked amount and unlocked amount in bifrost contract They are lazy to be serialized by command and hence doesn't appears while fetching storage. And them not appearing also makes tezos processing engine easy to implement
./fetch_bigmaps.bash
output:
usage: ./fetch_bigmaps [contract] [big_map_value] [map_key]
contract ----> 0 for bifrost, 1 for Fa12
big_map_value -----> accounts for big_map_account, locker for big_map_locker, balance for fa12_balance
map_key ----> alice for alice, bob for bob
For fetching account balances of alice [by default alice and bob are 2 keys in sandbox. Program can be modified for any address]
./fetch_bigmaps.bash 0 accounts alice
For fetching locked amount of alice. [Locked amount doesn't gets updated however the total locker balance gets updated, locker represents all amounts locked till now.]
After sending 100 tezos to cosmos locker balance of alice is 100
./fetch_bigmaps.bash 0 locker alice

For fetching Fa12 balance of alice
7 is balance after minting 12 tokens and sending 5 to cosmos from alice

Note: Initially when no addresses are registered in bigmap because no txs has taken place from that account, you might get an error like shown It doesn't mean program crashed but is generated because there is no such address in bigmap
