download & decompress in one go (no intermediate file):

mkdir -p data
curl -sL https://snapshots.tarn.hydration.cloud/hydration-archive-paritydb-13369397.tar.zst \
  | zstd -d --stdout - | tar -xf - -C data

run with matching flags — the node must be started with --pruning archive --database paritydb or it will refuse the db / resync from scratch:

docker run -d --name hydration \
  -v $(pwd)/data:/hydra/.local/share \
  -p 9944:9944 \
  galacticcouncil/hydra-dx:latest \
  --name my-node \
  --pruning archive \
  --database paritydb \
  --relay-chain-rpc-urls=wss://rpc.polkadot.io \
  --relay-chain-rpc-urls=wss://polkadot-rpc.publicnode.com \
  --rpc-port 9944 --rpc-external --rpc-cors=all --rpc-methods Safe

or with a bare hydradx binary:

hydradx -d ./data/hydradx --pruning archive --database paritydb \
  --relay-chain-rpc-urls=wss://rpc.polkadot.io

sha256: 03180b814ef880d74799978f6b3c5b6c9244faf005db0da04fad636b112885d3

curl -sL https://snapshots.tarn.hydration.cloud/hydration-pruned-rocksdb-13372967.tar.zst \
  | zstd -d --stdout - | tar -xf - -C /data

then start the node with --base-path /data/full. required flags: omit --database (or set rocksdb), keep --state-pruning 1000, use --relay-chain-rpc-urls:

hydradx --base-path /data/full \
  --state-pruning 1000 \
  --relay-chain-rpc-urls=wss://rpc.polkadot.io \
  --relay-chain-rpc-urls=wss://polkadot-rpc.publicnode.com
