Description

Handle Safe indexing events from Transaction Service and deliver as HTTP webhooks. This service should be connected to the Safe Transaction Service:

  • Transaction service sends events to RabbitMQ.
  • Events service holds a database with services to send webhooks to, and some filters like chainId or eventType can be configured.
  • Events service connects to RabbitMQ and susbscribes to the events. When an event matches filters for a service, a webhook is posted.

Events Service Diagram

Events supported

Some parameters are common to every event:

  • address: Safe address.
  • type: Event type.
  • chainId: Chain id.

Multisig Confirmation

{
  "address": "<Ethereum checksummed address>",
  "type": "NEW_CONFIRMATION",
  "owner": "<Ethereum checksummed address>",
  "safeTxHash": "<0x-prefixed-hex-string>",
  "chainId": "<stringified-int>"
}

MultisigTransaction (executed)

{
  "address": "<Ethereum checksummed address>",
  "type": "EXECUTED_MULTISIG_TRANSACTION",
  "safeTxHash": "<0x-prefixed-hex-string>",
  "failed": <bool>,
  "txHash": "<0x-prefixed-hex-string>",
  "chainId": "<stringified-int>"
}

MultisigTransaction (proposed, not executed)

{
  "address": "<Ethereum checksummed address>",
  "type": "PENDING_MULTISIG_TRANSACTION",
  "safeTxHash": "<0x-prefixed-hex-string>",
  "chainId": "<stringified-int>"
}

Multisig transaction deleted

{
  "address": "<Ethereum checksummed address>",
  "type": "DELETED_MULTISIG_TRANSACTION",
  "safeTxHash": "<0x-prefixed-hex-string>",
  "chainId": "<stringified-int>"
}

Incoming Ether

{
  "address": "<Ethereum checksummed address>",
  "type": "INCOMING_ETHER",
  "txHash": "<0x-prefixed-hex-string>",
  "value": "<stringified-int>",
  "chainId": "<stringified-int>"
}

Incoming/Outgoing token (ERC20)

{
"address": "<Ethereum checksummed address>",
"type": "INCOMING_TOKEN" | "OUTGOING_TOKEN",
"tokenAddress": "<Ethereum checksummed address>",
"txHash": "<0x-prefixed-hex-string>",
"value": "<stringified-int>",
"chainId": "<stringified-int>"
}

Incoming/Outgoing tokens (ERC721)

{
"address": "<Ethereum checksummed address>",
"type": "INCOMING_TOKEN" | "OUTGOING_TOKEN",
"tokenAddress": "<Ethereum checksummed address>",
"txHash": "<0x-prefixed-hex-string>",
"tokenId": "<stringified-int>",
"chainId": "<stringified-int>"
}

Message created/confirmed

{
"address": "<Ethereum checksummed address>",
"type": "MESSAGE_CREATED" | "MESSAGE_CONFIRMATION",
"messageHash": "<0x-prefixed-hex-string>",
"chainId": "<stringified-int>"
}

Developer documentation

Installation

Node 18 LTS is required.

$ npm install

Running the app

Docker compose is required to run RabbitMQ and Postgres

cp .env.sample .env

docker compose up -d

# development
$ npm run start

# watch mode
$ npm run start:dev

# production mode
$ npm run start:prod

Test

Note: It's important that web is not running during tests, as it can consume messages and tests will fail.

cp .env.sample .env

Simple way:

bash ./scripts/run_tests.sh

Manual way:

docker compose down
docker compose up -d rabbitmq db db-migrations
# unit tests
npm run test

# e2e tests
npm run test:e2e

# test coverage
npm run test:cov

Creating database migrations

By default, the local dockerized migrations database will be used (test should not be used as it doesn't use migrations). To use a custom database for migrations, set MIGRATIONS_DATABASE_URL environment variable.

Remember to add the new database entities to ./src/datasources/db/database.options.ts

bash ./scripts/db_generate_migrations.sh RELEVANT_MIGRATION_NAME

Endpoints

Available endpoints:

  • /health/ -> Check health for the service.
  • /admin/ -> Admin panel to edit database models.
  • /events/sse/{CHECKSUMMED_SAFE_ADDRESS} -> Server side events endpoint. If SSE_AUTH_TOKEN is defined then authentication will be enabled and header Authorization: Basic $SSE_AUTH_TOKEN must be added to the request.
