Simulations

Simulations in Invisium are a mechanism for calculating how a transaction or a sequence of transactions would modify blockchain state without broadcasting anything on-chain. The system executes the transaction logic inside an EVM-compatible environment and returns all changes that would occur: balance updates, storage writes, event logs, and potential reverts.

Invisium uses an optimized Rust-based EVM engine, which allows simulations to run with high speed and accuracy. The simulation environment mirrors real blockchain conditions: current state, pool reserves, token mechanics, and any custom logic present in smart contracts. Because of this, simulation results closely match actual execution outcomes.

The purpose of simulations is to understand the effect of an action before it happens. This is used to check whether a swap will succeed, verify that a token allows selling, detect honeypot behavior, estimate output amounts, validate initialization of contracts such as multisigs, test sequences of operations, or identify unexpected behavior that would lead to loss of funds or transaction failure. Invisium supports high-volume workloads: a single request can run up to about one hundred thousand simulation tasks, which reduces testing time for complex scenarios.

Simulations are applicable to any process where evaluating future state changes is required. Developers use them during smart-contract development, wallets use them to preview actions for users, and trading systems rely on them to validate behavior under different liquidity or price conditions. The result is a safe method to analyze how a transaction interacts with the EVM before committing it on-chain.
