Pull request overview

Refactors the codebase’s native-token handling by removing the custom EthPool wrapper and instead wiring CelerLedger to a chain’s canonical wrapped-native (WETH9-style) contract for the multi-party-funding path, while keeping the user-facing “native” semantics (address(0), msg.value) intact.

Changes:

• Replace EthPool with INativeWrap/nativeWrap throughout ledger storage, constructor wiring, funding flows, and getters.
• Rename native token type from ETH to NATIVE in protobuf/Solidity enums and update interfaces/docs accordingly (incl. depositETH → depositNative).
• Update tests, gas reports, deployment scripts, and documentation to reflect the new wrapped-native plumbing and removal of EthPool.
