Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[0.12.0] - 2021-11-12

Changed

  • bytesX arguments to seth calldata are automatically padded
  • seth 4byte command returns the response from querying 4byte.directory for a given function signature
  • seth 4byte-decode command queries 4byte.directory for matching function signatures, uses one to decode the calldata, and prints the decoded calldata
  • seth 4byte-event command returns the response from querying 4byte.directory for a given event topic
  • seth abi-encode command returns the ABI encoded values without the function signature
  • seth index command returns the slot number for the specified mapping type and input data
  • seth --from-fix command converts fixed point numbers into parsed integers with the specified number of decimals
  • seth run-tx now fetches contract source from etherscan if ETHERSCAN_API_KEY is set

Fixed

  • Address lookup no longer fails if ETH_RPC_ACCOUNTS is set, and ETH_FROM is an unchecksummed address
  • Contract creations with Dynamic fee transactions
  • seth debug correctly executes transactions
  • seth chain correctly identifies optimism-mainnet and optimism-kovan post regenesis

[0.11.0] - 2021-09-08

Added

  • seth basefee command returns basefee for the latest block, or any block with [blocknumber] parameter
  • seth namehash <name> to get the ENS namehash of a name
  • seth resolve-name <name> to resolve an ENS name to an address
  • seth lookup-address <address> to lookup the ENS name an address reverse resolves to
  • Dynamic transaction fee format transactions (EIP-1559) supported by introducing the flag --prio-fee and corresponding environment variable ETH_PRIO_FEE to seth and ethsign. If --prio-fee is provided (or ETH_PRIO_FEE) is set, 1559 transaction will be used and --gas-price will reflect the maximum gas price, rather than the absolute gas price.
  • If ETH_RPC_ACCOUNTS is set and the account corresponding to ETH_FROM exists in the keystore, Seth will sign the transaction locally and then publish it signed (previously it'd always send it to the node)

Changed

  • --gas-price will be used as max-fee when --prio-fee is set
  • [BREAKING] seth will no longer search Parity / OpenEthereum related keystores by default. These keystores can still be searched by setting the ETH_KEYSTORE environment variable.

Fixed

  • Fix --use bug
  • seth bundle-source writes the contents of standard-json to the current directory to enable better sourcemaps for multi-file etherscan source code.
  • seth estimate no longer sets a gas limit when estimating gas

[0.10.1] - 2021-03-22

Added

  • Thanks to an upgrade in ethsign, seth is more likely to find your ledger live account without having to set ETH_HDPATH.

Changed

  • updated nixpkgs to the 20.09 channel

Fixed

  • seth calldata returns correct abiencoding

[0.10.0] - 2021-01-26

Changed

  • seth combined-json was renamed to seth-solc and invokes solc using the --standard-json input.
  • seth bundle-source correctly interprets etherscan sources using standard json
  • the --gas-price argument can optionally accept a gwei suffix i.e. seth call --gas-price 100gwei ...

[0.9.4] - 2020-12-10

Added

  • seth --use can find solc versions in the nix store even if they are not present on PATH

Fixed

  • Correct help text for seth --use

[0.9.3] - 2020-11-29

  • seth --use searches directly for binaries in your path, rather than using nix run, giving a significant speed boost.

[0.9.2] - 2020-10-31

Added

  • Updated dapp and hevm

[0.9.1] - 2020-08-19

Added

  • New commands:

    • seth source <address> fetches the contract source from etherscan
    • seth bundle-source <address> fetches contract source and compiles to combined json
    • seth run-tx <tx-hash> [--debug, --source <file>, --state <repository>], set hevm options according to the options given and hevm exec
    • seth debug <tx-hash> [--no-src] downloads etherscan source, executes previous txs in block and enters into an hevm interactive session for the given tx. --no-src skips the first step.
    • seth --{max-uint,max-int,min-int} print the largest numbers (in hex) of a given bitsize
    • seth call --hevm executes a call via hevm, rather than the RPC
    • seth call --debug executes a call interactively via hevm
    • seth --verbose prints some seth debugging information to stderr

  • seth block can now be passed the --full option, which returns the full block.

  • hexdata can be concatenated with :, e.g. '0xaa:0xbb' will be read as '0xaabb'.

Changed

  • seth --to-{hex,wei,word,address,dec,int256,ascii,fix,uint256} and seth --from-{ascii,wei} can now read values from stdin.
  • seth call now accepts empty calldata and also create transactions via --create.
  • seth --abi-function-json no longer returns a singleton list, but rather the JSON object it contained.
  • Updated hevm to 0.41.0

[0.9.0] - 2020-05-25

Changed

  • hevm is now a dependency of seth.
  • seth calldata now implemented using hevm instead of ether.js, fixes several bugs.
  • Bytestring arguments to seth calldata must not be enclosed in double quotes.

[0.8.4] - 2020-02-21

Changed

  • seth {--to-uint256,--to-int256,--to-bytes32} now returns hex string with 0x prefix.
  • Removed ethabi dependency in favor of (already present) ethers.js.
  • 0x prefix is strictly required for bytestrings while using seth calldata.
  • When giving array arguments to seth calldata, each bytestring must be enclosed in double quotes.

Added

  • seth --calldata-decode command #338

[0.8.3] - 2019-08-08

Fixed

  • ABI JSON blob creation would fail for some solc reference types, e.g. bytes memory, since solc 0.5.0. solc was removed as a dependency and replaced with ethers.js.

0.8.2 - 2019-05-23

Fixed

  • Regression in seth send when ETH_RPC_ACCOUNTS was set

0.8.1 - 2019-05-7

Fixed

  • seth call, seth send and seth estimate were broken due to an update in 0.8.0, which has been reverted

0.8.0 - 2019-05-02

Added

  • Support for goerli and kotti testnets

Fixed

  • seth logs-etherscan now correctly handles its fourth optional argument, the ilk

0.7.0 - 2018-12-14

From this release on, changes, additions and removals will be documented in this changelog.

Changed

  • seth abi: use the current solc version in the pragma directive. #99
