USER STORY: Get operation base on hash using TezGraph as an indexer

[Innkst]

As a Taquito user that has an Operation Hash I want an API that I can use to fetch the Operation so that I can inspect the contents and status of that Operation

Background The Tezos RPC node does not offer the ability to fetch an operation by operation hash (May be implemented in the future see Tezos Issue 1131).

Acceptance criteria:

• Any operation (see examples in https://github.com/ecadlabs/taquito/issues/705) can be retrieved by hash using API for each of the indexers:

  • https://tezgraph.com/

• Support all operations where available for TezGraph(more indexers will be added in issues https://github.com/ecadlabs/taquito/issues/776 and https://github.com/ecadlabs/taquito/issues/777)

  • origination (o)
  • delegation (d)
  • reveal (r)
  • transaction (t)
  • ~activate_account (a)~
  • endorsement (e)
  • ~seed_nonce_revelation (s)~
  • ~double_endorsement_evidence (de)~
  • ~double_baking_evidence (db)~
  • ~proposals (p)~
  • ~ballot (b)~

• Return the following common fields

  • hash
  • kind
  • block
  • timestamp
  • level
  • source

• Return fields specific to each operation:

Non-functional:

• Extendable design: More Indexers, more generalized fields could be added in the future
• consider performance, scalability, security

OUT OF SCOPE:

• https://api.tzkt.io/#tag/Operations
• https://tzstats.com/docs/api/index.html
