Progress

Please don't hesitate to ask if you have any questions or suggestions, or if you would like a feature to be prioritized!

Core

Foundations of the app

run transactions in a simulated environment and remember activity on each chain

extensive

mock network condition/congestion (gas/blob gas price)

major

estimate gas fees on EVM L1s, Polygon and OP stack L2s

major

aggregate total fees, include/exclude transactions

minor

support Arbitrum orbit for gas fee on L1 submission

moderate

wallet/social login to save transactions (sync with local storage)

minor

Utilities

Main features facilitating the daily use/activity

provide helpers to generate mock data and quickly estimate costs for selected optimized solutions (e.g. GasliteDrop)

moderate

run a tx on multiple chains and provide a comparative estimation of gas spent on each

minor

share results so anyone can open them in savvy with the configuration and re-run the transactions

moderate

Extensions

Additional features that directly extend the use cases

paste a contract in a browser editor, deploy it and use it just like a regular forked contract

major

run ast on a pasted contract and provide inline recommendations to optimize both dependencies (e.g. OZ -> Solady) and known inefficient patterns

extensive

provide selected secure and optimized contracts to deploy in a click with mock data + estimate costs (e.g. Gaslite core, Solady libs)

major

impersonate a smart account (see Rhinestone, ERC7579); with utilities to follow the flow, add modules, etc

unknown

Infrastructure

Updates that might require breaking changes in core

provide a rpc to publish tests to the Tevm forked chain and keep the state (already possible in the opposite way; fork a local Hardhat node to which tests can be published)

unknown

extended account page, with more data to track across calls, e.g. tokens; show traces of the account's activity

major

Vision

Fundamental upgrades representative of the long-term vision for savvy

separate between two versions: advanced (intended for devs/experienced users) and "onboarding" for non-crypto natives, with detailed explanations, guidance and examples

major

use savvy as a browser "extension"/wallet; basically override the injected provider with the impersonated caller, and override the chain with a fresh fork—think of it as a "sandbox" mode for a DApp (see

Interceptor

, Fire , Impersonator)

extensive

And a lot of other possibilities, although not prioritized because there are already great tools for most of these. Like:

replicate transactions locally (given their hash + chain);
debug transactions by exploring state change;
copy a set of local transactions to get the multicall data and execute them on mainnet.
