pccontext

Chain contexts for PyCardano.

pccontext supplies a family of ChainContext implementations that plug into PyCardano’s transaction builder, along with a set of higher-level helpers for building the staking and governance transactions that PyCardano leaves to the caller.

It exists for three reasons:

  • More backends. Koios, Yaci DevKit and an offline transfer file have no equivalent in PyCardano.

  • Richer chain data. pccontext models the full Conway-era protocol parameter set and the complete genesis files, not just the subset the transaction builder needs.

  • Stake and governance state. Every context here answers stake_address_info(), which reports registration, rewards, pool delegation and DRep vote delegation for a stake address. PyCardano has no equivalent method.

If you are already using a PyCardano chain context and want to know what changes, start with Differences from PyCardano’s chain contexts.

from pccontext import KoiosChainContext

context = KoiosChainContext()

print(context.epoch)
print(context.protocol_param.min_fee_coefficient)
print(context.stake_address_info("stake1u9...")[0].reward_account_balance)
