- [SimulateTransaction](https://protochain.mintlify.app/api-reference/transaction/simulate-transaction.md): Dry-run a transaction against current ledger state without committing it.
- [SubmitTransaction](https://protochain.mintlify.app/api-reference/transaction/submit-transaction.md): Broadcast a fully signed transaction to the Solana network.
- [Commitment Levels](https://protochain.mintlify.app/concepts/commitment-levels.md): How Solana's three confirmation stages map to the CommitmentLevel enum — and when to use each.
- [Instructions and Transactions](https://protochain.mintlify.app/concepts/instructions-and-transactions.md): How instructions from the System Program and Token Program services compose into Protochain transactions.
- [Token Programs](https://protochain.mintlify.app/concepts/token-programs.md): SPL Token and Token-2022 are two incompatible Solana token programs. This page explains when to use each.
