Security

Proof of Security (PoSEC) discloses how platform assets are stored and uses one metric to answer one question: if all hot wallet assets were lost, could cold storage cover all user assets? Cold storage coverage = cold storage assets ÷ user assets; at or above 100%, cold storage alone can cover all user assets. Proof of Reserves (PoR) shows whether there are enough assets; PoSEC shows whether they are stored safely—they complement each other and neither replaces the other.

Crypto scam detectors help users identify suspicious websites, malicious tokens, risky smart contracts, and potentially dangerous wallet transactions before interacting with them.

Eligible users can activate Gate Guard for free on the Gate App or Web after meeting a security score of 80 or above, KYC 2, required security verifications, and a normal account status. Activation starts a 30-day Security Hardening Period—protection is not yet active until the score stays at 80 or above for 30 consecutive days and related conditions are met.

Gate Guard is Gate’s Account Protection Plan. It addresses direct losses from unauthorized asset transfers out of a Gate account. Eligible users may apply for reimbursement under the Plan Rules; eligibility and amount are subject to Gate’s final review. Gate Guard is not an insurance product and does not constitute an insurance contract, any form of insurance arrangement, or a promise of reimbursement.

An AI Agent is an artificial intelligence system that can plan tasks around specific goals, call external tools, and perform multistep operations. Unlike traditional chatbots, which primarily answer questions, AI Agents can connect to code repositories, databases, cloud services, enterprise collaboration platforms, and automation systems, moving beyond information processing into actual business execution. This capability improves work efficiency and is also making AI systems an increasingly integral part of enterprise access control frameworks.

In the crypto realm, prevention is always better than cure. Losing access to a cryptocurrency wallet or discovering that digital assets have been stolen can be difficult to resolve. Unlike traditional financial transactions like a bank transaction, a confirmed crypto transfers generally cannot be reversed simply by contacting a bank or payment provider. But recovering lost crypto may not be impossible even though chances are slim.

Cryptocurrency transactions are recorded on blockchains, making many transfers publicly traceable, but stolen crypto rarely stays in one place: after a theft, it often moves across multiple wallets, blockchains, bridges, decentralized exchanges, and privacy-focused services, which makes tracking and recovery far more difficult.

How can malicious EIP-7702 delegations drain a crypto wallet? Learn how delegated contracts work, how to detect unauthorized control, and how to respond safely.

Can stolen cryptocurrency be frozen or recovered? Explore blockchain transaction finality, stablecoin blacklists, exchange freezes, on-chain tracing, and legal recovery.

A crypto exchange hack is an unauthorized transfer of crypto assets out of exchange-controlled wallets after attackers bypass withdrawal risk controls and signing. Most large incidents involve compromised credentials or address authorizations rather than leaked private keys, and recovery depends on issuer freezes, tracing, and the operator's ability to pay.

Explore how EIP-7702 changes Ethereum wallet security, including account delegation, malicious authorization, asset theft risks, and ways to protect funds.

Revoking an EIP-7702 delegation takes two moves: call eth_getCode on the target chain to see whether the code field begins with the 0xef0100 23-byte designator, then sign a type 0x04 transaction that authorizes the zero address from inside the wallet. Checking every chain takes as long as the number of chains involved, and the revocation itself needs one onchain confirmation.

AI-assisted attacks can affect crypto security across smart contracts, wallets, account credentials, and infrastructure. Learn how projects, platforms, and users can identify risks and strengthen their defenses.

EIP-7702 delegation writes an EOA's code field as 0xef0100 plus the delegate address, so the account keeps its address and private key while running the delegate's code in its own context. A type 0x04 transaction carries the authorization tuple, and the delegation lasts until it is overwritten or revoked.

An AI-assisted exploit uses artificial intelligence to support vulnerability research, attack preparation, and malicious content generation. Explore its mechanisms, common forms, limitations, and security implications.
