Description

Generate ndjson for each bridge deposit over a particular range of blocks.

polycli ulxly get-deposits [flags]

Usage

This command will attempt to scan a range of blocks and look for uLxLy Bridge Events. This is the specific signature that we're interested in:

    /**
     * @dev Emitted when bridge assets or messages to another network
     */
    event BridgeEvent(
        uint8 leafType,
        uint32 originNetwork,
        address originAddress,
        uint32 destinationNetwork,
        address destinationAddress,
        uint256 amount,
        bytes metadata,
        uint32 depositCount
    );

If you're looking at the raw topics from on chain or in an explorer, this is the associated value:

0x501781209a1f8899323b96b4ef08b168df93e0a90c673d1e4cce39366cb62f9b

Each event that we counter will be parsed and written as JSON to stdout. Example usage:

polycli ulxly get-deposits \
        --bridge-address 0x528e26b25a34a4A5d0dbDa1d57D318153d2ED582 \
        --rpc-url https://eth-sepolia.g.alchemy.com/v2/demo \
        --from-block 4880876 \
        --to-block 6028159 \
        --filter-size 9999 > cardona-4880876-to-6028159.ndjson

This command will look for bridge events from block 4880876 to block 6028159 in increments of 9999 blocks at a time for the contract address 0x528e26b25a34a4A5d0dbDa1d57D318153d2ED582. The output will be written as newline delimited JSON.

This command is very specific for the ulxly bridge, and it's meant to serve as the input to the proof command.

Flags

  -a, --bridge-address string   address of the ulxly bridge
  -i, --filter-size uint        batch size for individual filter queries (default 1000)
  -f, --from-block uint         start of the range of blocks to retrieve
  -h, --help                    help for get-deposits
      --insecure                skip TLS certificate verification
  -u, --rpc-url string          RPC URL to read the events data
  -t, --to-block uint           end of the range of blocks to retrieve

The command also inherits flags from parent commands.

      --config string      config file (default is $HOME/.polygon-cli.yaml)
      --pretty-logs        output logs in pretty format instead of JSON (default true)
  -v, --verbosity string   log level (string or int):
                             0   - silent
                             100 - panic
                             200 - fatal
                             300 - error
                             400 - warn
                             500 - info (default)
                             600 - debug
                             700 - trace (default "info")
