# Blockchain Service - Production Environment Configuration
|
||
# =============================================================================
|
||
#
|
||
# Deployment: Server B (192.168.1.111)
|
||
# Role: Blockchain address derivation, balance queries, transaction monitoring
|
||
#
|
||
# Responsibilities:
|
||
# - Derive multi-chain addresses from public keys (KAVA, DST, BSC)
|
||
# - Monitor blockchain transactions for deposit detection
|
||
# - Publish WalletAddressCreated events to Kafka
|
||
# - Query wallet balances across supported chains
|
||
#
|
||
# Flow: mpc-service → blockchain-service → Kafka → identity-service
|
||
# (publicKey) (derive addresses) (event) (save addresses)
|
||
#
|
||
# Setup:
|
||
# 1. Copy to .env: cp .env.example .env
|
||
# 2. In Docker Compose mode, most values are overridden by docker-compose.yml
