Our state-sync RPC server for Airchains Testnet is

https://rpc1.airchains.t.cosmostaking.com

Create a reusable shell script such as `state_sync.sh` with the following code. The code will fetch important state-sync information (such as block height and trust hash) from our server and update your `config.toml` file accordingly.

                            
#!/bin/bash
SNAP_RPC="https://rpc1.airchains.t.cosmostaking.com"

LATEST_HEIGHT=$(curl -s $SNAP_RPC/block | jq -r .result.block.header.height); \
BLOCK_HEIGHT=$((LATEST_HEIGHT - 2000)); \
TRUST_HASH=$(curl -s "$SNAP_RPC/block?height=$BLOCK_HEIGHT" | jq -r .result.block_id.hash)

sed -i.bak -E "s|^(enable[[:space:]]+=[[:space:]]+).*$|\1true| ; \
s|^(rpc_servers[[:space:]]+=[[:space:]]+).*$|\1\"$SNAP_RPC,$SNAP_RPC\"| ; \
