0.24

  • Debian Bullseye and pyenv was picking up old web3-ethereum-defi version
  • Create a Docker script to check installation on Debian Bullseye

  • Add: TrackedLazyTimestampReader to help working with slow nodes
  • Add: MultiProviderWeb3.get_api_call_counts to see JSON-RPC API call stats across all providers
  • Fix: swap_with_slippage_protection(max_slippage) is BPS
  • API change: swap_with_slippage_protection(max_slippage=15) - change the default Uniswap v3 trade slippage tolerance from (unrealistic) 0.1 BPS to 15 BPS.
  • Fix: The madness of JSON-RPC providers abuse the error code -32000. We check for error message now instead of error code.
  • Internal change: When reading events, only notify progress bar when we have an event hit, to avoid unnecessary eth_getBlockByNumber calls for timestamps.

0.22.30

  • API change: Handle wait_and_broadcast_multiple_nodes() so that it will attempt to retry multiple providers multiple times before raising the last exception

0.22.29

  • Add launch_anvil(fork_block_number) option to create mainnet works on a specific block number. Naturally works only with archive nodes.
  • API change: If all providers fail in wait_and_broadcast_multiple_nodes(), raise the exception from the last provider.

0.22.28

  • More retryable JSON-RPC errors whitelisted. Now ValueError: {'code': -32701, 'message': 'Please specify address in your request or, to remove restrictions, order a dedicated full node here: https://www.allnodes.com/bnb/host'}.

0.22.27

0.22.22

  • Add: wait_and_broadcast_multiple_nodes to work around transaction broadcasts and confirmations failing on LlamaNodes
  • Fix: First workaround for JSON-RPC error: {'code': -32003, 'message': 'max priority fee per gas higher than max fee per gas'} in eth_defi.gas

0.22.21

  • Don't pin down pyarrow version to make it easier to use different Arrow reading backends

0.22.20

  • Add eth_defi.provider.broken_provider.get_almost_latest_block_number() for developer ergonomics when working with Ankr and LlamaNodes
  • If using FallbackProvider switch node providers in wait_transactions_to_complete because Ankr and LlamaNodes low service quality issues

0.22.19

  • Work around web3.exceptions.BlockNotFound with LlamaNodes.com

0.22.18

  • Added ChunkedEncodingError to automatically retryable errors. This error happens on LlamaNodes.com and is likely a quality of a service issue on their behalf.

0.22.17

  • Make testing and launch_anvil distrubuted safe by randomising Anvil localhost port it binds. Test now run in few minutes instead of tens of minutes. Tests must be still run with pytest --dist loadscope as individual test modules are not parallel safe.
  • Add eth_defi.broken_provider.set_block_tip_latency() to control the default delays for which we expect the chain tip to stabilise.

0.22.16

  • Work around BadFunctionCallOutput: Insufficient bytes exception: A special case of eth_call returning an empty result. This happens if you call a smart contract for a block number for which the node does not yet have data or is still processing data. This happens often on low-quality RPC providers (Ankr) that route your call between different nodes between subsequent calls, and those nodes see a different state of EVM. Down the line, not in the middleware stack, this would lead to BadFunctionCallOutput output. We work around this by detecting this condition in the middleware stack and triggering the middleware fall-over node switch if the condition is detected.
  • Set FallbackProvider to have the default 4 blocks latency for all latest calls, in get_default_block_tip_latency() so that fail over switches are more robust.

0.22.15

0.22.14

  • Add {'code': -32043, 'message': 'Requested data is not available'} to RPC exceptions where we assume it's an error we can either resume or switch to the next node provider. This error was encoureted with eth_getLogs when using LlamaNodes.

0.22.13

  • Allow passing request_kwargs to create_multi_provider_web3
  • When setting up TunedWeb3Factory use create_multi_provider_web3 to set up the connections instead pooled threads and processed
  • Switch to ujson for JSON-RPC decoding by default with create_multi_provider_web3
  • Fix test_block_reader tests

0.22.12

0.22.11

  • Add eth_defi.provider.llamanodes and work around issues with LlamaNodes.com

0.22.10

    where returning JSON-RPC responses differently formatted

0.21.6

  • Add HotWallet.sign_bound_call_with_new_nonce

0.21.5

  • Create extract_timestamps_json_rpc_lazy that instead of reading block timestamps upfront for the given range, only calls JSON-RPC API when requested. It works on the cases where sparse event data is read over long block range and it is likely only few timestamps need to be fetched in this range.
