Run bitcoind on regtest:
```
bitcoind -regtest -rpcport=8332
bitcoind -regtest
```
Create a new wallet, if needed:
```
bitcoin-cli -regtest -rpcport=8332 createwallet test
bitcoin-cli -regtest createwallet test
```
Load wallet (this command may take a while if you have lot of UTXOs):
```
bitcoin-cli -regtest -rpcport=8332 loadwallet test
bitcoin-cli -regtest loadwallet test
```
Get a new address:
```
address=$(./src/bitcoin-cli -regtest -rpcport=8332 getnewaddress)
address=$(bitcoin-cli -regtest getnewaddress)
```
Mine blocks to the previously generated address. You need at least 101 blocks before you can spend. This will take some time to execute (~1 min):
```
bitcoin-cli -regtest -rpcport=8332 generatetoaddress 101 $address
bitcoin-cli -regtest generatetoaddress 101 $address
```
Send 0.1 BTC at 5 sat/vB to another address:
```
./src/bitcoin-cli -named -regtest -rpcport=8332 sendtoaddress address=$(./src/bitcoin-cli -regtest -rpcport=8332 getnewaddress) amount=0.1 fee_rate=5
bitcoin-cli -named -regtest sendtoaddress address=$(bitcoin-cli -regtest getnewaddress) amount=0.1 fee_rate=5
```
See more example of `sendtoaddress`:
```
./src/bitcoin-cli sendtoaddress # will print the help
bitcoin-cli sendtoaddress # will print the help
```
Mini script to generate transactions with random TX fee-rate (between 1 to 100 sat/vB). It's slow so don't expect to use this to test mempool spam, except if you let it run for a long time, or maybe with multiple regtest nodes connected to each other.
Mini script to generate random network activity (random TX count with random tx fee-rate). It's slow so don't expect to use this to test mempool spam, except if you let it run for a long time, or maybe with multiple regtest nodes connected to each other.
```
#!/bin/bash
address=$(./src/bitcoin-cli -regtest -rpcport=8332 getnewaddress)
address=$(bitcoin-cli -regtest getnewaddress)
bitcoin-cli -regtest generatetoaddress 101 $address
for i in {1..1000000}
do
./src/bitcoin-cli -regtest -rpcport=8332 -named sendtoaddress address=$address amount=0.01 fee_rate=$(jot -r 1 1 100)
for y in $(seq 1 "$(jot -r 1 1 1000)")
do
bitcoin-cli -regtest -named sendtoaddress address=$address amount=0.01 fee_rate=$(jot -r 1 1 100)
done
bitcoin-cli -regtest generatetoaddress 1 $address
sleep 5
done
```
Generate block at regular interval (every 10 seconds in this example):
```
watch -n 10 "./src/bitcoin-cli -regtest -rpcport=8332 generatetoaddress 1 $address"
watch -n 10 "bitcoin-cli -regtest generatetoaddress 1 $address"
```
