Wait API

class populus.wait.Wait(web3, timeout=empty, poll_interval=empty)

Each chain object exposes the following API through a property Chain.wait.

• The timeout parameter sets the default number of seconds that each method will block before raising a Timeout exception.
• The poll_interval determines how long it should wait between polling. If poll_interval == None then a random value between 0 and 1 second will be used for the polling interval.

Wait.for_receipt(txn_hash, timeout=120, poll_interval=None)

Blocks for up to timeout seconds returning the transaction receipt for the given txn_hash.

Wait.for_block(block_number=1, timeout=120, poll_interval=None)

Wait.for_unlock(account=web3.eth.coinbase, timeout=120, poll_interval=None)
