CIC Chain Events
Filters live (and past) transactions on Celo and emits relevant events to a NATS JetStream sink for further processing/indexing.
Prerequisites
- Linux OS (amd64) or Docker
- Postgres >= 14
- Celo geth with GraphQL API enabled
- NATS server with JetStream enabled
Usage
The provided docker-compose.yaml
is the fastest way to get up and running. Bring up the Postgres and NATS conatiners with docker-compose up -d
1. Run migrations
Run the SQL migrations inside the migrations
folder with psql
or tern
(recommended).
2. Update the config
The base config is described in config.toml
. Values can be overriden with env variables e.g. to disable metrics, set METRICS_GO_PROCESS=false
.
3. Start the service
Compiling the binary
Run make build
or download pre-compiled binaries from the releases page.
Then start the service with ./cic-chain-events
Optional flags:
-config
-config.toml
file path-debug
- Enable/disable debug level logs-queries
-queries.sql
file path
Docker
To pull the pre-built docker image:
docker pull ghcr.io/grassrootseconomics/cic-chain-events/cic-chain-events:latest
Or to build it:
DOCKER_BUILDKIT=1 COMPOSE_DOCKER_CLI_BUILD=1 docker-compose -f docker-compose.build.yaml build --progress plain
4. NATS JetStream consumer
A consumer with the following NATS JetStream config is required:
- Durable
- Stream:
CHAIN.*
(Seeconfig.toml
for stream subjects)
Benthos (Benthos can act as a JetStream consumer) example.
# config.yaml
input:
label: jetstream
nats_jetstream:
urls:
- nats://127.0.0.1:4222
subject: "CHAIN.*"
durable: benthos
deliver: all
output:
stdout:
codec: lines
Then run:
benthos -c config.yaml
