# Testing eclair and lightningd
|
||
|
||
## Configure bitcoind to run in regtest mode
|
||
Important: you need a segwit version of bitcoin core for this test (see https://github.com/sipa/bitcoin/tree/segwit-master).
|
||
Make sure that bitcoin-cli is on the path and edit ~/.bitcoin/bitcoin.conf and add:
|
||
```shell
|
||
server=1
|
||
regtest=1
|
||
rpcuser=***
|
||
rpcpassword=***
|
||
```
|
||
|
||
To check that segwit is enabled run:
|
||
```shell
|
||
bitcoin-cli getblockchaininfo
|
||
```
|
||
and check bip9_softforks:
|
||
|
||
```
|
||
...
|
||
"bip9_softforks": {
|
||
"csv": {
|
||
"status": "active",
|
||
"startTime": 0,
|
||
"timeout": 999999999999
|
||
},
|
||
"witness": {
|
||
"status": "active",
|
||
"startTime": 0,
|
||
"timeout": 999999999999
|
||
}
|
||
}
|
||
```
|
||
|
||
## Start bitcoind
|
||
Mine enough blocks to activate segwit blocks:
|
||
```shell
|
||
bitcoin-cli generate 500
|
||
```
|
||
##
|
||
Start lightningd (here we’ll use port 46000)
|
||
```shell
|
||
lightningd --port 46000
|
||
```
|
||
##
|
||
Start eclair:
|
||
```shell
|
||
mvn exec:java -Dexec.mainClass=fr.acinq.eclair.Boot
|
||
```
|
||
## Tell eclair to connect to lightningd
|
||
|
||
```shell
|
||
curl -X POST -H "Content-Type: application/json" -d '{
|
||
"method": "connect",
|
||
"params" : [ "localhost", 46000, 3000000 ]
|
||
}' http://localhost:8080
|
||
```
|
||
Since eclair is funder, it will create and publish the funding tx
|
||
|
||
Mine a few blocks to confirm the funding tx:
|
||
```shell
|
||
bitcoin-cli generate 10
|
||
```
|
||
eclair and lightningd are now both in NORMAL state.
|
||
You can check this by running:
|
||
```shell
|
||
lightning-cli getpeers
|
||
```
|
||
or
|
||
```shell
|
||
curl -X POST -H "Content-Type: application/json" -d '{
|
||
"method": "list",
|
||
"params" : [ ]
|
||
}' http://localhost:8080
|
||
```
|
||
|
||
|
||
## Tell eclair to send a htlc
|
||
We’ll use the following values for R and H:
|
||
```
|
||
R = 0102030405060708010203040506070801020304050607080102030405060708
|
||
H = 8cf3e5f40cf025a984d8e00b307bbab2b520c91b2bde6fa86958f8f4e7d8a609
|
||
```
|
||
|
||
You’ll need a unix timestamp that is not too far into the future. Now + 100000 is fine:
|
||
```shell
|
||
curl -X POST -H "Content-Type: application/json" -d "{
|
||
\"method\": \"addhtlc\",
|
||
\"params\" : [ 70000000, \"8cf3e5f40cf025a984d8e00b307bbab2b520c91b2bde6fa86958f8f4e7d8a609\", $((`date +%s` + 100000)), \"021acf75c92318d3723098294d2a6a4b08d9abba2ebb5f2df2b4a8e9153e96a5f4\" ]
|
||
}" http://localhost:8080
|
||
```
|
||
|
||
## Tell eclair to commit its changes
|
||
```shell
|
||
curl -X POST -H "Content-Type: application/json" -d "{
|
||
\"method\": \"sign\",
|
||
\"params\" : [ \"d3f056a084e266ad06ea1ca28a1e080ca07c6b61fac7ce116e48a5c31d688eee\" ]
|
||
}" http://localhost:8080
|
||
```
|
||
## Tell lightningd to fulfill the HTLC:
|
||
```shell
|
||
./lightning-cli fulfillhtlc 03befb4f8ad1d87d4c41acbb316791fe157f305caf2123c848f448975aaf85c1bb 0102030405060708010203040506070801020304050607080102030405060708
|
||
```
|
||
Check balances on both eclair and lightningd
|
||
|
||
## Close the channel
|
||
```shell
|
||
./lightning-cli close 03befb4f8ad1d87d4c41acbb316791fe157f305caf2123c848f448975aaf85c1bb
|
||
```
|
||
Mine a few blocks to bury the closing tx
|
||
```shell
|
||
bitcoin-cli generate 10
|
||
```
|
||
The channel is now in CLOSED state
