1. Int3face node
2. Int3face observer (configured for the BTC regtest)
3. BTC regtest node

​

Inbound Transfer​

1. We need an int3 address to send funds to

We can generate new address by int3faced keys add "$your_key_name".

2. Lets verify that this address doesn’t have DOGE tokens in the Int3face

int3faced q bank balances int31nx72wqe9js9n0tvk9c2w4zwgwv6kecp0n4zllt

3. Select an UTXO to spend

bitcoin-cli listunspent

4. Build raw transaction from the UTXO you selected

• Take the txid and vout from the UTXO you’re going to spend

• Add the DOGE vault address and the amount to send
• Add the change address to get remaining tokens back (to get address of your current node run bitcoin-cli listreceivedbyaddress 0 true)
• Leave a small amount of tokens to pay the fee (0.1 should be enough)
• Add data entry with the hex encoded recipient address
  • Encode int31nx72wqe9js9n0tvk9c2w4zwgwv6kecp0n4zllt at the (online converter)[https://www.rapidtables.com/convert/number/ascii-to-hex.html]

vins='[
    {
        "txid": "5023f0be5c236ac4c1be6a6c7bcc5dcc2ece77f5ccf1cb52cd590e5c4c1407d9",
        "vout": 0
    }
]'

vouts='{
    "bcrt1qjrcwv9848uvvcdzvyplmgms6dr62zp6qz5f5ch": 10.0,
    "bcrt1qkx2l45vnq5d4883n0ny9fhdcqqz79cqsva44q6": 39.99,
    "data": "696E7433316E783732777165396A73396E3074766B39633277347A77677776366B656370306E347A6C6C74"
}'

bitcoin-cli createrawtransaction "$vins" "$vouts"

5. We can verify that the transaction is correct

bitcoin-tx -regtest -json "$raw_tx"

6. Sign the transaction

bitcoin-cli signrawtransactionwithwallet $raw_tx

7. Broadcast signed transaction to the BTC

bitcoin-cli sendrawtransaction $signed_tx

8. Generate a block to include our transaction in the chain

bitcoin-cli -generate 1

9. Check your balance on the Int3face chain.

int3faced q bank balances int31nx72wqe9js9n0tvk9c2w4zwgwv6kecp0n4zllt

Now, we can see BTC tokens in our wallet.

​

Outbound Transfer​

1. Generate new BTC address

bitcoin-cli getnewaddress
bcrt1qu80e2kt8ery9589gec9em8qhzkvxqkdy8ecr6x

2. Request an outbound transfer from the bridge module

int3faced tx bridge outbound-transfer bcrt1qu80e2kt8ery9589gec9em8qhzkvxqkdy8ecr6x bitcoin-btc 100000000 --from doge_test

3. We can check our balance again to see that DOGE tokens in Int3face were burt

int3faced q bank balances int31nx72wqe9js9n0tvk9c2w4zwgwv6kecp0n4zllt

4. Generate a block in BTC to include transaction from the vault

bitcoin-cli -generate 1

5. Check DOGE balance of the address we created before

bitcoin-cli listunspent 1 9999999 '["bcrt1qu80e2kt8ery9589gec9em8qhzkvxqkdy8ecr6x"]'

Now, we can see BTC tokens in our wallet.
