v0.2.0: Bitcoin,Solana, Sui indexer

v0.2.0 Release Notes

New Chain Support

Bitcoin Indexer

• Full UTXO-based transaction indexing with native BTC transfer detection
• Prevout resolution for accurate sender address and fee calculation
• Mempool support for 0-confirmation transaction tracking via dedicated worker
• Configurable confirmation threshold (default: 6 for mainnet)
• Deep reorg protection with configurable rollback window
• SegWit and bech32 address normalization

Solana Indexer

• Slot-based indexing with finalized commitment level
• Native SOL transfers via System Program
• SPL Token transfers (Transfer and TransferChecked instructions)
• Token-2022 program support
• Parallel block fetching with configurable concurrency for high throughput
• Token metadata resolution from pre/post-token balance data

Sui Indexer

• Checkpoint-based indexing via gRPC (not HTTP JSON-RPC)
• Native SUI and token transfer detection using balance change heuristics
• Real-time checkpoint streaming with background subscription
• Batch checkpoint fetching with 10-concurrent request pool
• TLS and connection pooling support

Improvements

• PubkeyStore filtering added to Tron and Sui indexers, consistent with EVM and Solana — filters transactions at the indexer level by monitored addresses
• PubkeyStore refactored to remove kvstore dependency (a5e64c5)
• Tron performance improvements: reduced memory allocations and optimized processing (648bf03)
• Standardized transaction types: consolidated to TxTypeTokenTransfer and TxTypeNativeTransfer across all chains (9d2b615)
• Parallel processing configurable per chain via throttle.parallel: true in YAML config
