  summary = "Pure-Lua client for Ethereum and EVM-compatible blockchains",
  detailed = [[
A Lua client for Ethereum, Polygon, Arbitrum, Optimism, Base, BSC,
Avalanche, and any other EVM-compatible JSON-RPC endpoint.

v0.3 adds: ABI encode/decode for dynamic types (bytes, string, arrays)
alongside the static types; abi.encode_packed (Solidity abi.encodePacked);
event-log decoding (decode_event / event_topic); RLP decoding (strict
canonical form); EIP-2930 (Type 1) transactions and access lists on both
EIP-2930 and EIP-1559; and real JSON-RPC batch requests (one round-trip,
responses matched by id) via rpc:batch / client:batch.

v0.2's transaction signing (Legacy with EIP-155, EIP-1559, ECDSA via
libsecp256k1, RLP encoding, arbitrary-precision wei arithmetic via libgmp)
and v0.1's read-only surface are unchanged.

Read-only modules run on PUC-Rio Lua 5.1+. The signing path requires
LuaJIT and the system libraries libgmp (pacman -S gmp /
apt install libgmp-dev) and libsecp256k1 (pacman -S libsecp256k1 /
apt install libsecp256k1-dev). evm.signer.AVAILABLE reflects whether
the libsecp256k1 backend loaded.

Zero Lua-side install-time dependencies (no lua-cjson required — JSON
is in-tree). Lua 5.1 users need LuaBitOp ('luarocks install luabitop'
or your distribution's equivalent) since 5.1 has no built-in bitwise
operators; the compat shim picks it up automatically.

CI-verified on Lua 5.1, 5.3, 5.4, LuaJIT 2.1; locally on Lua 5.5.
