bcash-instadump

Instantly dump BCH, get free BTC!

USE AT YOUR OWN RISK!

Install

$ npm install -g bcash-instadump

CLI usage

Instadump via Changelly

$ bcash-instadump --input txid:vout:amount:key --payout 1BitcoinEaterAddressDontSendf59kuE --email [email protected]

Sell BCH from the unspent output specified in --input (amount in satoshis, key is base58 WIF) via Changelly and send converted BTC to the Bitcoin address provided in --payout.

If you already have an account on Changelly, specify the account's password with --password. Otherwise, a new account will be created with the provided --email.

Specify --feerate to control the transaction fee (in satoshis/byte). Defaults to 200.

You can specify --input multiple times, or specify a CSV file instead with --inputs utxos.csv. All the inputs will be joined together in a single transaction (see "Privacy Concerns" below).

--cookie writes/reads the Changelly authentication cookie to a file. Use if you're invoking bcash-instadump multiple times.

Send to any address

$ bcash-send --input txid:vout:amount:key --output 1BitcoinEaterAddressDontSendf59kuE:ALL

Create a bcash transaction with the provided inputs and outputs. ALL is special cased to send the maximum available amount, minus tx fees.

Add the --broadcast flag to broadcast the transaction via TBD.

Recommended usage

1. Prepare a CSV file with a list of your UTXOs (txid,vout,amount,key format).

For Bitcoin Core, you can use:

bitcoin-cli listunspent | jq -cr '.[] | [.txid,.vout,.amount,.address]' | tr -d '[]"' \ | awk -F, '{"bitcoin-cli dumpprivkey "$4 | getline key; print $1 FS $2 FS $3 FS key }' \ > utxos.csv

2. Move all of your bitcoins to new addresses. The keys provided to this software should be entirely empty of BTC before touching this software.

3. bcash-instadump --inputs utxos.csv --payout [1YourAddress]

4. Profit!

Privacy concerns

• Joining your unspent outputs together will reveal the link between your addresses/outputs to the entire world, on both the public BTC and BCH blockchains. It is recommended to invoke bcash-instadump multiple times, once for each unspent output being sold (creating a separate 1-in,1-out tx each time).

• Selling all of your unspent outputs to the same Changelly account and/or from the same IP address will reveal the link between your addresses/outputs to the Changelly operators, hackers who gained access to Changelly servers, and governments that can serve Changelly with a warrant.

• Transactions are broadcasted to the bcash network using XXX, which would link the transaction and your IP address together. You can set --proxy or broadcast the raw transaction manually.
