# Alertio > Real-time DeFi risk monitoring. Alertio watches lending positions, stablecoin pegs, perp funding and market liquidity across EVM chains, Solana and TON, and sends an alert when a threshold you set is crossed — via Telegram, email, or webhook. The distinction that organises this site: market data platforms publish **market state** (protocol TVL, rates, yields) thoroughly and for free. What they do not hold is the link between that state and **your** position, because they do not know which positions are yours. Alertio watches user state — your health factor, your peg exposure, your withdrawable liquidity — and is quiet until something crosses a line. Monitoring is read-only and address-based: a public address is read the way a block explorer reads it. No signature, no connection, no key material. ## Explainers - [Health Factor, Explained](https://www.alertio.io/guides/health-factor): What a health factor actually is, why it isn't LTV or your P&L, what happens below 1.0, and how to defend it. - [Funding Rates, Explained](https://www.alertio.io/guides/funding-rates): Who pays whom on a perpetual, why funding is charged on notional not margin, and what extreme rates signal. - [Utilization, Explained](https://www.alertio.io/guides/utilization): Why the least-watched number on a lending dashboard decides whether you can withdraw, and what 95%+ really means. - [Liquidations, Explained](https://www.alertio.io/guides/liquidations): What actually executes when a position goes under, what the penalty costs, why cascades feed themselves, and the defenses that work. - [Stablecoin Depegs, Explained](https://www.alertio.io/guides/stablecoin-depegs): Fiat-backed, delta-neutral, and CDP dollars each break differently — what breaks each one, and why the price moves before the news. - [Webhook Alerts, Explained](https://www.alertio.io/guides/webhook-alerts): Getting an HTTP POST when a health factor crosses the threshold you set — choosing that number, the payload, and why the obvious implementation sends 1,440 alerts a day. - [DeFi Alert Tools: How to Choose](https://www.alertio.io/guides/defi-alert-tools): Four kinds of tool answer to "DeFi alerts" and they solve different problems — what each sees, what it is blind to, and where Alertio is the wrong choice. - [Stablecoin Redemption Liquidity](https://www.alertio.io/guides/stablecoin-redemption-liquidity): Supply is the room, redemption is the door. Live measurement of how much USDC, USDT and USDS could actually leave — and why money earning yield is the shallowest exit. - [Tokenized Gold Proof of Reserves](https://www.alertio.io/guides/tokenized-gold-proof-of-reserves): Neither Tether Gold nor PAX Gold has an on-chain reserve feed — what backs them, what you can actually check, and why a live feed still might not mean independent. - [Reserve Attestation vs Audit vs PoR](https://www.alertio.io/guides/reserve-attestations): What an attestation actually proves, why calling it an audit overstates it, and the snapshot date that decides whether the number means anything. - [On-Chain Proof of Reserves](https://www.alertio.io/guides/onchain-proof-of-reserves): How a Chainlink PoR feed is consumed, and the three ways a live reserve feed misleads you — including the failed read that looks like zero collateral. - [Proof of Reserves, Explained](https://www.alertio.io/guides/proof-of-reserves): Attestations vs live feeds vs on-chain oracles, and how mismatched snapshots can show a shortfall that doesn't exist. ## Alert types by risk - [Liquidation risk](https://www.alertio.io/alerts#liquidation): Am I about to lose collateral? Anything borrowed against collateral can be taken from you when the ratio between the two moves far enough. The number that governs it — a health factor, a collateral ratio, a margin level — is public and updates continuously, but it only matters in the minutes before it crosses. These alerts watch that number on your specific position and fire on the way down, at a level you choose rather than at the protocol's. Covers 13 alert types, each at https://www.alertio.io/alerts/. - [Peg and backing risk](https://www.alertio.io/alerts#peg): Is this asset still worth what it claims? A stablecoin is a promise that a token equals a dollar, and a liquid staking token is a promise that it equals the asset it wraps. Both promises are priced by a market that can disagree with them at any time. Because these assets are usually held as collateral, a peg that slips does not just lose you the difference — it moves every position that counts the asset at par. Covers 3 alert types, each at https://www.alertio.io/alerts/. - [Rate and yield risk](https://www.alertio.io/alerts#rates): Is this position still worth holding? Not every loss arrives as a liquidation. A borrow rate that triples overnight, a vault yield that quietly compresses, or funding that flips against a perp will erode a position that never comes close to a margin call. Rates move on utilization and positioning, both of which change without any announcement, so the spread you opened a trade for is not the spread you are still earning. Covers 9 alert types, each at https://www.alertio.io/alerts/. - [Liquidity and exit risk](https://www.alertio.io/alerts#liquidity): Can I actually get out? A lending market at 99% utilization is described as capital efficient right up to the moment you try to withdraw and find that the money is lent out. The same applies to a thin DEX pool, a vault whose depositors are leaving, or a market a protocol has frozen. Solvency and accessibility are different things, and the gap between them opens well before anyone announces it. Covers 7 alert types, each at https://www.alertio.io/alerts/. - [Market and protocol events](https://www.alertio.io/alerts#market): What just changed around me? These describe conditions rather than your position: a price level, a crowded perp market, a gas spike, a governance vote that reprices collateral. On their own they are market state, which is freely available and easy to over-consume. They earn a place here when they are the leading edge of something that reaches your position — a parameter change opening for a vote, or open interest climbing into a move.
