Name Bazaar

A peer-to-peer marketplace for the exchange of names registered via the Ethereum Name Service.

See at

Smart-contracts can be found here.

Starting a dev server

In a terminal, start a ganache blockchain


Note that this uses docker and will try to pull trufflesuite/ganache-cli:v6.12.1 image if you don't have it.

Alternatively, you can connect directly to one of ethereum testnet networks - e.g. goerli. In order to do this, specify correct smart contract addresses and :web3 properties in the ./config.edn file. Example config file can be found in docker-builds/server/config.example.edn.

Open another terminal, start a repl and build the dev server (with figwheel repl)

lein repl

Figwheel will prompt for a connection for the repl instance.

Open another terminal, run the compiled server script, which should connect to the figwheel repl.

node dev-server/name-bazaar.js

(If you have problems re-running this command, try removing dev-server folder and try to start the server again)

Redeploy smart-contracts and generate mock data

You can (re)deploy contracts with

truffle migrate --reset

and (optionally) generate some samle dev data from the clojurescript REPL by running the following command:


Redeployment / generation can take a long time, please be patient.

Start dev UI

If you wish to connect to the dev server discussed above, open a separate terminal, and build the client-side ui

lein repl

You can then connect to the server through a web browser at http://localhost:4541

Semantic UI

To build the Semantic UI pieces of the app you need to have gulp installed. Note that gulp 4.x does not work, you need a 3.x version.

npm install [email protected]^3.9.0 --save

Then use our handy script:

./ build or ./ watch

Depending upon how you'd like to work.

Start a development UI for client-side development only

If you're only focusing on working with the UI, you can start a UI interface which connects to the production server using mainnet.

lein repl
(start-ui! :ui-only? true)

In separate terminal, start the supplied docker nginx server

docker-compose build nginx
docker-compose up nginx

# Visit website at http://localhost:3001

Note: using this client is using the main ethereum network, it is ill-advised to carry out transactions unless you know what you are doing!

Backend (server) tests:

lein doo node "server-tests"

(If you have problems running the tests, try to remove server-tests directory and try re-running the tests again)

The doo runner will autobuild the test and re-run them as the watched files change. Alternatively:

lein cljsbuild once server-tests
node server-tests/server-tests.js

Frontend (browser) tests:

To run browser tests use the following command:

lein npm run cypress-open

Tests connect to a running app on http://localhost:4541. It is recommended to run the tests with clear ganache network, otherwise the tests will be slower or fail.

Development env through nginx:

docker-compose build nginx
docker-compose up nginx

and start (start-ui!), (start-server!) as usual, but open the site on http://localhost:3001

Build for production

Following commands are used to build system for production

lein build-prod-server
lein build-prod-ui
lein build-css

# To build all 3 in parallel use
lein build-prod

# To run prod server
node server/name-bazaar.js

Testnet deploy

To run server in docker container use image district0x/namebazaar-server, e.g.:

docker run --name=namebazaar-server \
    --net=host \
    -v /path/to/config.edn:/configs/namebazaar.config.edn \

You can choose between tags dev, latest (intended for QA deploys) and release (intended for production deploy). As for the config file, you can find an example in docker-builds/server/config.example.edn. Of particular interest is providing correct addresses of smart contracts on the blockchain you'll link the app to.

For UI use the district0x/namebazaar-ui image:

docker run --name=namebazaar-ui \
    --net=host \

Note that there is no passing of config file for UI: currently for any change of UI config you need to build a new image (see the next section). The hardcoded configuration is at src/name_bazaar/ui/config.cljs.

Deploying Name Bazaar smart contracts

First, you need to specify deployments secrets in config.edn. For example:

{:truffle {:goerli {:privateKeys ["0x0000..."]
                    :infuraKey "0000...."
                    :ensAddress "0x00000000000C2E074eC69A0dFb2997BA6C7d2e1e"
                    :registrarAddress "0x57f1887a8BF19b14fC0dF6Fd9B2acc9Af147eA85"
                    :publicResolverAddress "0xE264d5bb84bA3b8061ADC38D3D76e6674aB91852"
                    :reverseRegistrarAddress "0xD5610A08E370051a01fdfe4bB3ddf5270af1aA48"}}}

ENS address are not in documentation, but in some random post on forum

Then, you can use truffle to deploy the contracts just by running the following command in bash:

# you can also use `--network mainnet` - see truffle-config.js for deployment details for more information.
truffle migrate --network goerli

Linting and formatting smart contracts

We use ethlint for linting solidity files. You can use lein npm run ethlint and lein npm run ethlint-fix to run the linter.

You can use lein run-slither to run slither to statically analyze the smart contracts. However, this tool reports many false positives.
