Security & trust

Architecture you can defend in a board meeting.

We never custody funds. We can't move them without your signature. Every recommendation includes a full reasoning trace, and every report is hash-anchored on Ethereum.

Important risk disclosure

This is not financial advice. 0xDEF.AI provides AI-assisted analysis and transaction preparation tools for informational purposes only. DeFi protocols carry smart-contract risk, oracle risk, and liquidity risk — including the potential for total loss of funds. Past strategy performance is not indicative of future results. You remain solely responsible for all on-chain decisions and for ensuring that any activity complies with applicable law in your jurisdiction. Always conduct your own due diligence before executing any transaction.

Non-custodial. Your assets are held exclusively in your Gnosis Safe. 0xDEF.AI holds no private keys and cannot unilaterally move your funds at any trust stage.

Custody model

Self-custody, always

Funds live in your Gnosis Safe. 0xDEF.AI is, at most, a co-signer at higher trust stages — never an owner. You can revoke us in one Safe transaction.

Ownership verification

On-chain proof, not paperwork

We don't trust an email address to claim a Safe. We send a nonce challenge that the Safe must sign via EIP-1271. The signature is verified on-chain (isValidSignature). Spoofing is mathematically impossible.

Execution

Transactions you can read before signing

Every Safe tx is simulated against Tenderly. You see decoded calldata, expected balance changes, gas, and revert reasons. Nothing executes until your quorum signs.

Reasoning trail

Auditable decisions

Every recommendation stores: model version, prompt, data sources (with timestamps), tool calls, and policy-check results. Hash anchored on EAS. Replay any decision months later.

Primary sources & references

The security claims on this page are grounded in publicly verifiable specifications and open-source implementations. We encourage independent verification.

EIP-1271: Standard Signature Validation for Contracts
The Ethereum standard that lets a Safe contract validate a signature on-chain via isValidSignature(bytes32,bytes). This is the mechanism we use to verify ownership without trusting an off-chain claim.

Ethereum Attestation Service (EAS)
The on-chain attestation protocol we use to hash-anchor AI reasoning reports. Any party can verify a report's authenticity and timestamp independently, without trusting 0xDEF.AI's servers.
