From cfd3136fdf752258d3f7fc7130d7d4ea1a004f2a Mon Sep 17 00:00:00 2001 From: Mohsin Zaidi <2236875+smrz2001@users.noreply.github.com> Date: Tue, 25 Nov 2025 11:27:33 -0500 Subject: [PATCH 1/5] feat: add anchor-evm crate for EVM-based anchoring MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add new crate implementing EVM blockchain anchoring for Ceramic streams. - Supports self-anchoring directly to EVM chains without Merkle trees - Implements gas management with dynamic pricing and retry logic - Uses environment variables for RPC endpoints to avoid hardcoded secrets - Includes comprehensive tests for Gnosis Chain integration ๐Ÿค– Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- Cargo.lock | 64 +++++ Cargo.toml | 4

Fix tx_hash_to_cid: wrap hash with Keccak256 code + ETH_TX codec (0x93) instead of re-hashing with SHA2-256 - Fix AnchorProof parameter order: (chain_id, root, tx_hash, tx_type) - Add chain ID validation after connecting to provider - Implement retry logic with exponential backoff - Add wallet balance logging for gas cost tracking - Update default confirmations from 1 to 4 (matching JS implementation) Code cleanup: - Remove unused GasConfig (alloy handles gas estimation automatically) - Remove unused get_root_block function and getRootBlock interface - Consolidate gnosis_test.rs into integration_test.rs Testing: - Add test_cid_to_bytes32_matches_js to verify JS compatibility - Add test_tx_hash_to_cid_matches_js to verify JS compatibility - Add test_anchor_service_with_evm for full AnchorService flow testing (merkle tree building, EVM anchoring, time event creation) Documentation: - Update README with comprehensive test documentation - Document all environment variables for integration tests -
