Latency
- Execution depends on Bitcoin block confirmation
- Transactions are not instantaneous, expect multiple-minute delays
- User-facing dApps should design for asynchronous flows and optimistic UI updates
No Synchronous Bitcoin State
- Contracts cannot query Bitcoin state in real-time
- All operations are based on indexed, confirmed inscriptions
- Any assumptions of instant UTXO or balance visibility might lead to incorrect logic
Indexer Determinism Assumptions
- Contract state is reconstructed by deterministic replay of inscriptions
- Indexers must process inscriptions in order and handle reorgs gracefully
- For developers, this means contracts should not assume simultaneous or out-of-order execution
- Conceptually similar to Ethereum replay tests, but the underlying chain is Bitcoin
