Peerswap Playground

This PeerSwap Playground provides a docker stack that comprises bitcoind, elementsd, 2x lnd nodes and 2x peerswap clients. It connects everything together, initializes the wallets, and creates a channel between the two nodes.

You can use this to get familiar with Peerswaps.

Usage

Start nodes:

docker compose up

Initialise the nodes:

./scripts/init.sh

Get the pubkey of one of the nodes:

PUBKEY=$(./bin/lncli lnd2 getinfo  | jq -r '.identity_pubkey')

Get details of channel connecting the two nodes:

CHANID=$(./bin/lncli lnd1 listchannels | jq -r --arg pubkey "$PUBKEY" '.channels[] | select(.remote_pubkey == $pubkey) | .chan_id')

Initiate a swapout:

./bin/pscli peerswap1 swapout --channel_id $CHANID --sat_amt 1000000 --asset lbtc

Mine 3 blocks on the Liquid network:

./bin/elements-cli -rpcwallet=peerswap1 -generate 3

Wait ~10 seconds...

sleep 10

Track progress:

./bin/pscli peerswap1 listswaps
./bin/pscli peerswap2 listswaps

Check liquid balances:

./bin/pscli peerswap1 lbtc-getbalance
./bin/pscli peerswap2 lbtc-getbalance

Check channel balance:

./bin/lncli lnd1 listchannels | grep -A 3 $CHANID
./bin/lncli lnd2 listchannels | grep -A 3 $CHANID

Clean everything:

docker compose down --volumes
