lib eth.rb v0.5.0 beta

lib eth.rb v0.5.0 is a full-blown, modern, breaking, major rewrite of the ruby-eth gem. it is 100% spec-covered and 100% api-documented.

• coverage: https://app.codecov.io/gh/q9f/eth.rb
• api docs: https://q9f.github.io/eth.rb/

you broke my gem!

don't worry, I'm still maintaining the legacy gem v0.4.x releases. Just put 'eth', '< 0.5' in your gemspec.

• v0.4.x releases: https://github.com/se3000/ruby-eth/releases

feature overview

• Secp256k1 Key-Pairs and Encrypted Ethereum Key-Stores (JSON)
• EIP-55 Checksummed Ethereum Addresses
• EIP-155 Replay protection with Chain IDs (with presets)
• EIP-191 Ethereum Signed Messages (with prefix and type)
• EIP-712 Ethereum Signed Type Data
• EIP-1559 Ethereum Type-2 Transactions (with priority fee and max gas fee)
• EIP-2028 Call-data intrinsic gas cost estimates (plus access lists)
• EIP-2718 Ethereum Transaction Envelopes (and types)
• EIP-2930 Ethereum Type-1 Transactions (with access lists)
• ABI-Encoder and Decoder (including type parser)

notes on upgrading to 0.5.0

• Eth::Key no longer requires monkey-patched OpenSSL/FFI and uses native Secp256k1 instead

  Eth::Key.new priv: "30137644b564785d01420f8043f043d74dcca64008e57c59f8ce713a0005a54b"

• Eth::Address is returned as object in most places instead of a string, use .to_s to get a checksummed address string

  Eth::Key.new(priv: "30137644b564785d01420f8043f043d74dcca64008e57c59f8ce713a0005a54b").address.to_s

• signature recovery was moved from the Eth::Key class to a Eth::Signature module

  Eth::Signature.verify "Hello World!", signature, address

• EIP-155 replay protection is implemented everywhere, see Eth::Chain module

  chain_id = Eth::Chain::OPTIMISM

• Eth::Tx.new params and Eth::Tx.parse hex always try to detect the transaction type (EIP-1559, EIP-2930, legacy)
