Built so wallets never sign blind.

TxShield is the last checkpoint between a Solana transaction and the network. We're the engineering team behind it.

Mission

Wallets, trading bots and DEX frontends sign transactions every second of every day. The vast majority are safe — but the bad ones are catastrophic. Sandwiches, drainers, honeypots, slippage cliffs. They ruin a user once and you never see them again.

TxShield is the last checkpoint between a wallet and Solana mainnet. We simulate every transaction before it broadcasts, score it against fourteen detection vectors in parallel, and hand back a single verdict in under 80 ms. Fast enough to drop in front of every send.

Who runs this

We're a small engineering team operated by Grundlabs, a software company based in Germany. TxShield is one of several products in the portfolio (alongside ChainEvidence for crypto-fraud investigation, and Paya for stablecoin payment infrastructure).

Both ChainEvidence and Paya are production users of the TxShield API today, which means we eat our own cooking — every API change ships through our own products before customers ever see it.

How we build

• One chain at a time. Solana mainnet is live and tested end-to-end. EVM is in private beta. BTC and TRX are scoping. We don't ship coverage we haven't validated on real traffic.
• Boring infrastructure. No microservice circus, no staging-only theatre. Two regions, active-active, status visible at /status.
• Public roadmap. What we're building, what's behind, what's next — all on the docs page when there's something concrete to share.
