|
It's default. No special flags required. But if in RPCDaemon you using custom `--private.api.addr` flag, then set same
|
|
|
|
|
value to `--txpool.api.addr` flag.

Add `--txpool.disable` to erigon. External TxPool works in separated process and **require** external Sentry. TxPool
|
|
|
|
|
connect to Erigon and Sentry. RPCDaemon connect to TxPool. Build by:
|
2021-09-17 11:21:21 +00:00
|
|
|
|
|
|
|
|
```
|
|
|
|
|
make txpool
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
Start by:
|
|
|
|
|
|
|
|
|
|
```
|

|
|
|
# Add `--txpool.disable` flags to Erigon.
|
2021-09-17 11:21:21 +00:00
|
|
|
./build/bin/sentry
|
|
|
|
|
./build/bin/txpool
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
To change address/port of Erigon or Sentry:
|
|
|
|
|
|
|
|
|
|
```
|
|
|
|
|
./build/bin/txpool --private.api.addr localhost:9090 --sentry.api.addr localhost:9091 --txpool.api.addr localhost:9094
|
|
|
|
|
```
|
|
|
|
|
|
|
|
|
|
## Increase pool limits

## ToDo list
|
|
|
|
|
|
2021-10-28 10:50:49 +00:00
|
|
|
[] Hard-forks support (now TxPool require restart - after hard-fork happens)
|
2021-09-18 13:58:23 +00:00
|
|
|
[] Add pool to docker-compose
|
|
|
|
|
[] Add pool (db table) - where store recently mined txs - for faster unwind/reorg.
|
|
|
|
|
[] Save history of local transactions - with 1 day expiration
|
