SIMULATE / TXMORA
Preview Before You Sign.
A simulation can make a complex transaction easier to reason about by estimating how it would execute against a particular view of blockchain state. TXMORA presents simulation as decision support—not a guarantee, certification or replacement for reviewing the transaction itself.

Why simulate
Inspect the possible outcome, not just the prompt.
Wallet prompts often expose technical fields without showing the complete economic effect of execution. A simulation can help estimate which assets may move, whether a call is likely to revert and what resources might be consumed. The value is in surfacing the expected sequence before a signature is authorized.
- Expected balance deltas
- Call success or likely revert signals
- Gas or resource estimates when supported
Execution context
Every preview has a scope and a timestamp.
An on-chain transaction executes against state at inclusion time. A preview operates on an earlier observed or forked state, and that state may be stale by the time a user signs. Price movements, block ordering, mempool conditions and contract upgrades can all affect a later outcome. A responsible interface should make the simulation block or freshness context available.
- State can change between preview and inclusion
- External calls may depend on changing data
- Private order flow can differ from public assumptions
Network coverage
Simulation is chain-specific engineering.
EVM-compatible networks share much of the transaction envelope and virtual-machine behavior, but chain configuration, precompiles, fee rules and RPC capabilities still matter. Solana transactions use a different instruction and account model; a simulator must understand programs, account access and compute behavior rather than translating EVM assumptions. Unsupported inputs should fail clearly, not receive a fabricated result.
- EVM processing requires compatible execution state
- Solana needs program- and account-aware handling
- Unsupported transactions should be identified explicitly
Reliability
Show evidence, assumptions and failure modes.
A useful simulation report separates observed facts from estimates. It should retain the transaction input, report the environment and block context used, and describe when an operation could not be faithfully modeled. Failed calls, missing state and unsupported contracts are signals to pause and investigate—not details to conceal behind a confident summary.
- Distinguish decoded facts from estimates
- Preserve the execution assumptions
- Never convert missing data into a safety claim
