Mender
Launch app
Early access

Paste a failed Solana transaction, find out why it failed, and get a repaired version that simulates clean.

Block explorers explain what happened. Mender proposes repairs and proves with simulation that they would land, and it exposes this as an API that agents can call mid-loop.

Questions.

Short answers. The docs have the rest.

What is Mender?

Paste a failed Solana transaction, find out why it failed, and get a repaired version that simulates clean. Block explorers explain what happened. Mender proposes repairs and proves with simulation that they would land, and it exposes this as an API that agents can call mid-loop.

What works today?

Mender is in development. Every feature is on the status list with what ships next, and the app opens in a sample workspace so you can see how it will work.

Do I need a wallet?

No. You can explore without one. Connecting a Solana wallet only shares your public address so Mender can read your balances; it never asks you to sign a transaction.

Who is it for?

Agent builders, bot developers and active DeFi users who hit failed transactions and don't want to read program logs.
