🎯 Motivations

Rainbow is inspired by the following trends:

• Crypto-assets and DeFi becoming mainstream,
• Advent of the Internet of Blockchains’ world with more cross-chain applications and communications,
• Crypto options trading growing bigger than the spot market, like in traditional Finance.

The crypto derivatives markets are expected to grow a lot more in the upcoming years. Specifically, the options markets will see the biggest growth, because in Finance, Option market is much bigger than the underlying spot market. This is lagging in Crypto, when we look at Deribit's volume (the main centralized venue for Crypto Options), compared to Perpetuals future.

We participated to hackathons and have won super prices: Ethereum's EthGlobal Hackathon, Solana's Ignition Hackathon and Encode Club's Hack DeFi.

🏛️ Supported exchanges

• Deribit: Centralized exchange. Main venue for crypto Options trading.

• Delta Exchange: Centralized exchange for futures, options and interest rate swaps on 50 underlying cryptocurrencies.

• Lyra (Ethereum): DeFi protocol for trading options based on Layer 2, Optimism, using a custom AMM.

• Thales Optimism and Polygon, DeFi protocol for binary options (exotic options).

• Zeta (Solana): DeFi options protocol built using Serum order books.

🏗 Deprecated exchanges

• PsyOptions (Solana): DeFi options protocol build on Serum order books. But PsyOptions pivoted to DeFi Options Vaults (DOV).

• Opyn (Ethereum): DeFi options protocol using TheGraph & 0x. But Opyn also pivoted to more vaults like products Squeeth, Crab...

🏎️ Run it from source code

Rainbow can be used as a CLI or with a frontend as our official instance: https://teal.finance/rainbow.

📑 Requirements

• Go v1.18+ (single requirement for the CLI)
• Node v14+
• Yarn v1.20+
• Docker v20 (optional)
• Podman v3 (optional)

Rainbow can be used in the CLI, without requiring Node, Yarn, Docker…

Snap provides a simple way to install these requirements on many Linux distributions:

snap install go   --classic
snap install node --classic  # installs yarn too

# check
go   version
yarn versions

On Debian/Ubuntu, the command sudo apt install golang may install an older version. Check it with apt list --all-versions golang golang-1.*. To install a more recent Go version, you may try:

sudo apt purge   golang
sudo apt install golang-1.18

The Dockerfile can be used equally with Docker or Podman.

📥 Clone the Rainbow Git repo

git clone https://github.com/teal-finance/rainbow
cd rainbow

🪃 Run the CLI

The Rainbow project provides a Command Line Interface (CLI) to let users play from their terminal. The command ./cli retrieves (few minutes) and prints a pretty nice table of all options.

go run ./cmd/cli

⚒️ Makefile for server & web

See the make help output.

🔧 Build

make all     # Build both backend and frontend
make server  # Build the backend only
make front   # Build the frontend only
make clean   # Clean all

🚀 Run

The run targets do not depend on the above build targets. You do not need to make build before make run.

make run        # Run the backend in dev mode
make run-ui     # Run the frontend in dev mode

To serve the static website using the Rainbow backend only, as in production:

make clean -j && make all -j && make run

🐋 Container

make container-run  # Build and run backend + frontend
make container-rm   # Stop and remove all

The container targets try to use docker, then podman.

The container-run also opens a browser window on http://localhost:1111/ and prints the container logs indefinitely.

Use CTRL+C to stop the log printing. This does not stop, the container. To stop the container simply use make container-rm.

The two other containers targets are not needed to be invoked manually:

make container-build  # Build the container image
make container-stop   # Stop/remove the container

The container parameters can be customized: 🙂

make container-run expose=80 port=80 base=/rainbow/

🖐️ Manual build & run

Backend

The frontend requires the server API.

go build ./cmd/server && ./server

# or

go run ./cmd/server     # same as "make run"

Frontend

To run the Vue3 frontend in dev mode. Similar to make run-ui:

cd frontend
yarn
yarn dev --open

In prod mode, the backend serves the web static files from frontend/dist. Same as make frontend/dist:

cd frontend
yarn
yarn build

Finally open http://localhost:8090

🐳 Manual build/run of the container

This Git repo provides a Dockerfile for a secured and light all-in-one container image: 30 MB.

The image contains the hardened sever executable and the frontend static files.

The container enables by default the CORS, the export ports and a rate limiter. Some of these features can be customized using environments variables.

The following commands configures the server listening on port 2222 (published to port 1111) and frontend using CORS with http://localhost:1111. See also the comments within the Dockerfile for the details.

podman build --build-arg addr=http://localhost:1111 --build-arg port=2222 -t rainbow .
podman stop rainbow # if already running in background
podman run --rm -p 0.0.0.0:1111:2222 -d --name rainbow rainbow
podman logs --follow rainbow

Open http://localhost:1111.

The above manual commands can be obtained using the Makefile:

make container-run addr=http://localhost:1111 expose=1111 port=2222

🚩 Server command line flags

Rainbow embeds a complete HTTP server, including a rate limiter, an export port (Prometheus monitoring), and more. For more details see the underlying project Teal.Finance/Garcon.

🛣️ API

To test the API endpoints, run the backend:

make run

or using the container alternative:

make container-run expose=8090

/v0/options

The /v0/options endpoint accepts optional parameters.

Filtering

Progressive filtering:

• /v0/options/BTC (only the BTC-based options)
• /v0/options/BTC/2022-04-29 (only the BTC-based options expiring on 2022-04-29)
• /v0/options/BTC/2022-04-29/Deribit (only the BTC-based options expiring on 2022-04-29 from Deribit)
• /v0/options/BTC/2022-04-29/Deribit/csv (the same but in a CSV file, see the supported formats)

The general URL pattern:

/v0/options/{asset}/{expiry}/{provider}/{format}

The API may be tested with cURL:

curl localhost:8090/v0/options

curl localhost:8090/v0/options/BTC

curl localhost:8090/v0/options/BTC/2022-04-29

curl localhost:8090/v0/options/BTC/2022-04-29/Deribit

curl localhost:8090/v0/options/BTC/2022-04-29/Deribit/csv

Query string

Moreover, the parameters can also be passed using the query string:

• /v0/options?asset=BTC&asset=ETH (multiple underlying assets)
• /v0/options?asset=BTC&expiry=2022&provider=Deribit&format=csv

POST method

The API also supports the POST form:

curl localhost:8090/v0/options -d asset=BTC -d asset=ETH

curl localhost:8090/v0/options -d asset=BTC -d expiry=2022 -d provider=Deribit -d format=csv

The POST form is recommended for privacy reasons since it hides your query within the encrypted request body when using HTTPS.

Awesome expiry filtering

The expiry filtering matches for the beginning of the dates:

• /v0/options/ALL for ALL options and any expiry date
• /v0/options/ALL/2022 for expiry dates in 2022
• /v0/options/ALL/2022-04 for expiry dates in April 2022
• /v0/options/ALL/2022-04-01 for April 1st 2022

Supported formats

The {format} parameter is the last one at any position.

• /v0/options (default is JSON in the browser)
• /v0/options/json (download a file in JSON format)
• /v0/options/csv (CSV file)
• /v0/options/tsv (TSV = Tab-Separated Values)
• /v0/options/BTC/csv (only the BTC-based options in CSV)
• /v0/options/ALL/2022-06/csv (all options expiring in June 2022 in CSV)

The current supported formats are JSON, CSV and TSV. Depending on user requests, more formats may be supported such as JSON-LD, JSON Lines (or NDJSON, see JSON streaming), Avro, Parquet, DataFrame, Excel, Google Sheets Docs.

HTTP header

The "Accept" HTTP header is also supported:

curl localhost:8090/v0/options -H "Accept: application/json"

curl localhost:8090/v0/options -H "Accept: text/csv"

curl localhost:8090/v0/options -H "Accept: text/tsv"

/v0/graphql

This endpoint is currently designed to meet the requirements of the frontend. This endpoint should not yet used by API users because we may drop it in a further release.

However, other websites can display the Rainbow screener using this GraphQL API. Please contact us. 😉

/v0/graphiql (with an "i")

This interactive GraphQL endpoint is used in developer mode to tune the frontend GraphQL queries.
