No More Waiting: Execute Crypto Transactions at Light Speed
Cosigner is an AI-powered co-signer that automatically approves safe, routine transactions on your Gnosis Safe multisig, blending multi-sig security with single-sig speed.
How Cosigner Works (AI + Gnosis Safe)
Cosigner integrates directly with Gnosis Safe, the leading Ethereum multisig wallet (securing ~$40B in assets). It acts as an additional signer on your multisig, using AI to decide when to co-sign.
- Transaction Created1
- A Safe transaction is initiated (by a DAO member, fund trader, dApp, or you).
- AI Analysis2
- Cosigner's backend runs the transaction through rigorous checks – it simulates the execution and scans for anomalies or red flags. An LLM (Large Language Model) then evaluates the context in plain language to ensure it makes sense.
- Instant Co-Sign or Alert3
- If all checks pass – policy rules met, simulation clean, AI sees no issues – Cosigner automatically signs the transaction, counting toward your multisig quorum. If something seems off, it withholds its signature and flags it for manual review instead.
- Completion4
- With Cosigner's signature added, only the remaining human approvals are needed. Routine transfers can thus finalize in seconds with just one human, whereas anything unusual still gets full human scrutiny.
Users have a dashboard to adjust policies (like whitelisted addresses or spending limits), view the AI's reasoning, and override settings. You're always in control – you can pause auto-signing or require explicit AI approval requests for certain transactions.
Key Features & Benefits
With Cosigner, you get the perfect balance of security, speed, and control.
- Ironclad Security
Every transaction is vetted by an AI risk engine before signing. Cosigner performs off-chain simulation and anomaly detection (flagging new recipient addresses, unusual amounts, or malicious contract code). An embedded LLM adds a human-like context check, catching issues that static rules might miss.
Prevent fraud or mistakes before they happen
- Speed & Efficiency
Turn a 2-of-3 multisig into a one-click experience. Cosigner's instant approvals give you near single-sig agility without sacrificing multisig safety. Treasury transactions that fit your safe criteria (e.g. within normal size, to trusted addresses) get co-signed in seconds, even at 3 AM.
Move funds or execute trades in real-time
- Automation with Control
Save time by automating the mundane approvals. Cosigner auto-signs recurring payments, payroll, or weekly swaps according to your predefined rules. You set the policies – e.g. whitelist known addresses, define max transfer amounts, daily limits, etc.
Maintain ultimate control at all times
- Transparency & Peace of Mind
Every Cosigner decision comes with an explanation. The dashboard shows why the AI signed or why it flagged something, helping build trust in the system. You'll get real-time notifications (email/Telegram) when the AI co-signs or blocks a transfer, so you're always in the loop.
Sleep easy knowing an AI is auditing each transaction 24/7
