Uniswap Watcher

Setup

Create a postgres12 database for the job queue:

sudo su - postgres
createdb uni-watcher-job-queue

Enable the pgcrypto extension on the job queue database (https://github.com/timgit/pg-boss/blob/master/docs/usage.md#intro).

Example:

postgres@tesla:~$ psql -U postgres -h localhost uni-watcher-job-queue
Password for user postgres:
psql (12.7 (Ubuntu 12.7-1.pgdg18.04+1))
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

uni-watcher-job-queue=# CREATE EXTENSION pgcrypto;
CREATE EXTENSION
uni-watcher-job-queue=# exit

Create a postgres12 database for the address watcher:

sudo su - postgres
createdb uni-watcher

Update environments/local.toml with database connection settings for both the databases.

Run

Build files:

$ yarn build

Run the server:

$ yarn server

# For development.
$ yarn server:dev

# For specifying config file.
$ yarn server -f environments/local.toml

Start the job runner:

$ yarn job-runner

# For development.
$ yarn job-runner:dev

# For specifying config file.
$ yarn job-runner -f environments/local.toml

Start watching the factory contract:

$ yarn watch:contract --address 0xContractAddress --kind <contract-kind> --startingBlock <start-block>

# For specifying config file.
$ yarn watch:contract -f environments/local.toml --address 0xContractAddress --kind <contract-kind> --startingBlock <start-block>

Example:

$ yarn watch:contract --address 0xfE0034a874c2707c23F91D7409E9036F5e08ac34 --kind factory --startingBlock 100

Start watching the NonFungiblePositionManager contract:

Example:

$ yarn watch:contract --address 0xB171168C0df9457Ff3E3D795aE25Bf4f41e2FFE3 --kind nfpm --startingBlock 100

To fill a block range:

yarn fill --startBlock <from-block> --endBlock <to-block>

# For specifying config file.
$ yarn fill -f environments/local.toml --startBlock <from-block> --endBlock <to-block>

Example:

$ yarn fill --startBlock 1000 --endBlock 2000

Test

To test the watchers locally:

  • Deploy the Uniswap contracts
  • Watch the Factory and NonFungiblePositionManager contracts
  • Send transactions to trigger events

See https://github.com/vulcanize/uniswap-v3-periphery/blob/watcher-ts/demo.md for instructions.

Smoke test

To run a smoke test:

  • Start the server and the job-runner.

  • To build contracts for tests, run the command below in root of the repository:

    $ yarn build:contracts
    
  • Run:

    $ yarn smoke-test
