⁠Mempool DipDup

DipDup for mempool indexing

⁠Config

Fully compatible config with default DipDup YAML config. To index mempool you should add section mempool in your config. For example:

version: 0.0.1

datasources:
  tzkt_mainnet:
    kind: tzkt
    url: https://api.tzkt.io
  node_mainnet:
    kind: tezos-node
    url: https://rpc.tzkt.io/mainnet

contracts:
  myaccount:
    address: tz1...

mempool:
  settings:
    keep_operations_seconds: 172800
    expired_after_blocks: 60
    keep_in_chain_blocks: 10
    mempool_request_interval_seconds: 10
    rpc_timeout_seconds: 10
  indexers:
    mainnet:
      filters:
        kinds:
          - transaction
        accounts:
          - myaccount
      datasources:
          tzkt: tzkt_mainnet
          rpc: 
            - node_mainnet

database:
  kind: sqlite
  path: mempool.db

⁠Config in details

Section mempool contains two keys: settings and indexers. settings part is general settings for the dipdup service. indexers is set of used indexers.

⁠settings section

• keep_operations_seconds - how long store operations in seconds. When operations store more than the keep_operations_seconds period it will be removed from database. Exclude in_chain status. For in_chain operations use parameter keep_in_chain_blocks. Default: 172800 (2 days).

• expired_after_blocks - after blocks count pointed in expired_after_blocks paramater operation's status will be set to expired. Default: 60.

• keep_in_chain_blocks - how long store operations with status in_chain in blocks. Default: 10.

• mempool_request_interval_seconds - request interval to tezos node for receiving mempoool operations in seconds. Default: 10.

• rpc_timeout_seconds - timeout for request to tezos node. Default: 10.

⁠indexers section

This section is used to create custom mempool indexers. You can create 1 indexer per network. Network is the primary key of indexer. For example:

 indexers:
    mainnet:
        ...
    edonet:
        ...
    delphinet:
        ...

Every indexer has 2 settings: filters and datasources.

filters is the your filtration rules.

• kinds - array of mempool operation's kinds. It may be any of activate_account, ballot, delegation, double_baking_evidence, double_endorsement_evidence, endorsement, origination, proposal, reveal, seed_nonce_revelation, transaction Default: transaction.

• accounts - array of tezos tz and KT addresses which will be used for filtering by source, destination and etc.

datasources is section for setting URLs of tezos nodes and TzKT.

• tzkt - TzKT url

• rpc - array of tezos nodes URL.
