API Docs

• Docs: https://docs.bitgem.tech/

Requirements

• Bitcoind node
• Esplora backend (optional, only if you need address index)

Minimum System Requirements:

• 32 GB RAM
• 8 Core CPU
• ~250 GB SSD for the indexer db (Dec 2023)

Run with docker

1. Make sure that bitcoind is running and synced. Bitcoind should be available at http://bitcoind:8332 or http://localhost:8332
2. Set up directory for the indexer db
3. Run

docker run -d --name exotic-indexer \
    -v ./index-dir:/db \
    -v ./bitcoind-root-dir:/bitcoin \
    --stop-timeout 900 \
    -e BITCOIN_RPC_HOST=bitcoin \
    -e BITCOIN_RPC_PORT=8332 \
    -e DATA_DIR=/db \
    -e BITCOIND_DIR=/bitcoin \
    -e ESPLORA_URL=https://blockstream.info/api/ \
    lebonchasseur/exotic-indexer:master

If you want to run for testnet there is no difference, just point to the testnet bitcoind directory

docker run -d --name exotic-indexer \
    -v ./index-dir:/db \
    -v ./bitcoind-root-dir:/bitcoin \
    --stop-timeout 900 \
    -e BITCOIN_RPC_HOST=bitcoin \
    -e BITCOIN_RPC_PORT=8332 \
    -e DATA_DIR=/db \
    -e BITCOIND_DIR=/bitcoin/testnet3 \
    -e ESPLORA_URL=https://blockstream.info/testnet/api/ \
    lebonchasseur/exotic-indexer:master

Build your own docker image

You can also build your own docker image docker build -t exotic-indexer . and run it with the same command as above.

Develop

1. Rename env to .env and substitute the values for your system
2. Run docker compose up in the root directory to bring up the testnet instance of bitcoind
   • the bitcoind container is configured to use arm64v8 by default for Apple sillicon support. Adjust this for your system.
3. go get -v
4. Run and debug with VS Code or the editor of your choice
