blockchain/docker/docker-compose.testnet.yml

# Lethean Testnet Network Simulation
# Spins up a 3-node testnet with explorer, wallet RPC, and trade services
#
# Usage:
#   docker compose -f docker-compose.testnet.yml up -d
#   docker compose -f docker-compose.testnet.yml logs -f node1
#   docker compose -f docker-compose.testnet.yml down -v
#
# Nodes discover each other via exclusive-node flags.
# Node1 is the seed node, Node2 and Node3 connect to it.
