# Seeds Utility to generate the seeds.txt list that is compiled into the client (see [src/chainparamsseeds.h](/src/chainparamsseeds.h) and other utilities in [contrib/seeds](/contrib/seeds)). Be sure to update `PATTERN_AGENT` in `makeseeds.py` to include the current version, and remove old versions as necessary (at a minimum when GetDesireableServiceFlags changes its default return value, as those are the services which seeds are added to addrman with). The seeds compiled into the release are created from the `dnsseed.dump` output file of a [Bitcoin ABC Seeder](/src/seeder) that has been running for at least 30 days. The scripts below assume that the `dnsseed.dump` file from the mainnet seeder has been copied to `seeds_main.txt` and the `dnsseed.dump` file from the testnet seeder has been copied to `seeds_test.txt`. python3 makeseeds.py < seeds_main.txt > nodes_main.txt python3 makeseeds.py < seeds_test.txt > nodes_test.txt python3 generate-seeds.py . > ../../src/chainparamsseeds.h ## Dependencies Ubuntu: sudo apt-get install python3-dnspython
