MLS Wallet's contracts are open source and audited by Certora and yAudit. Den is SOC 2 Type II certified.

You set the rules: who approves, how much, and how often.

All three layers enforce them, so funds can't move outside your rules, even with a stolen signature or a breach of Den's own servers.

MLS Wallet is the first institutional wallet with no single point of failure.

Every transaction must pass 3 independent layers: your signers, Den's Guardian, and onchain smart contracts.

Attackers would need to break all 3 at once. With MPC or multisigs, breaking one is enough.

But their wallets had single points of failure:

• Bybit: a tampered wallet app
• Radiant: malware on signers' devices
• Drift: signers tricked into pre-signing
• Kelp DAO: one verifier, fed bad data
• Exchanges: breached hot wallets

One compromise. Funds gone.

They all thought they were safe.

They used multisigs, MPC, hardware wallets, audited contracts and cold storage.

Textbook best practices.

Last month, Binance lost $6.4B in about 20 minutes. Before that, eight major attacks took $2.3B from crypto teams.

Today we're putting an end to it.

Easy 🫡

An easy way to improve security is by using two different frontends for your @safe txs.

I enter on Safe.
I execute on @OnChainDen

Easy.

There will be scheduled maintenance on Den on
Wednesday July 23 at 11:45PM UTC.

Den may be unavailable at this time.

Any updates on maintenance will be shared here.

Of course! Let us know if any other questions

We have our own transaction API for internal use, so we can run without Safe's transaction API if needed. We also ingest data from Safe's transaction API so you can create transaction on one interface and sign on a different interface.

The latter case, ingesting data from Safe's transaction API, has been temporarily paused while an issue related to incorrect transaction data is being resolved by Safe. More info here: x.com/safe/status/19…

We don't currently have a local version that users can run.
