Block number of v1 transactions
V1 transfers still come from transaction_history.json
which lacks the block number. So v1 transfers do not use negative block number. The following query gives nothing.
query OldTransfers {
transfer(limit: 10, where: {blockNumber: {_lt: 0}}) {
id
}
}
The transactions should be taken from the blockchain history as well as certifications. And an additional foreign key on event should be added as written in #18.
