lib eth.rb 0.5.14 is a feature release.
Packed Solidity Encoding
This release ships the packed solidity encoder enabling smart contract interactions that require tightly packed encoding.
types = ["int16", "bytes1", "uint16", "string"]
values = [
-1, "\B", 0x03, "Hello, world!",
]
Eth::Abi.solidity_packed(types, values)
# => "ffff42000348656c6c6f2c20776f726c6421"Unlike standard ABI coding, which includes type-specific padding and length prefixes, packed encoding concatenates values directly without extra metadata.
EIP-7702 type-4 transactions
This release implements EIP-7702 transactions, including authorization lists.
auth_list = [
Tx::Eip7702::Authorization.new(
chain_id: 31337,
address: "700b6a60ce7eaaea56f065753d8dcb9653dbad35",
nonce: 2,
recovery_id: 0,
r: "a4f2c5243c3d6d82168ef35b3d3df1e50cefee1bc212c769bd1968061c395260",
s: "7f346c1804300b96d687a90ce5bcea0883c12bc45b6a8a294e29ff7c02b42a65",
),
Tx::Eip7702::Authorization.new(
chain_id: Chain::ETHEREUM,
address: "700b6a60ce7eaaea56f065753d8dcb9653dbad35",
nonce: 11,
r: "acec76e844690cf2f58317d13d910b270cf0b9e307db8094402dc46b4f456a81",
s: "570d6ea163a505896aa2674d56810033cd4d03b13787065b5abe57cde485e52a",
recovery_id: 0,
)]
Tx.new({
# ...
authorization_list: auth_list,
# ...
})EIP-7702 introduces transaction type 0x04, and it’s part of the proposal to support Ethereum accounts that can temporarily become smart contracts. This is tied to "transient smart contract accounts", an evolution toward more flexible account abstraction.
