What VIGIL catches

Did something just change?

Each rule reads real onchain events, and each alert carries the transaction, block and actor behind it.

Contract ownership transferred
Proxy upgraded to a new implementation
Contract paused or unpaused
Admin, minter, pauser or upgrader role granted or revoked
Large mint or burn, as a share of supply
Large transfer out of a deployer or treasury wallet
Large or unlimited approval given by a watched wallet
A watched deployer deploys a new contract
Liquidity removed from a pool
Multisig owners or threshold changed

From block to alert

Six steps, every block.

Nothing is guessed along the way. Each step works from what the chain itself returned, and keeps the proof. How it works ↗

01
Watch
Paste an address. VIGIL reads what it is, proxy, owner, token, multisig or pool, and suggests the rules that suit it.
02
Read
Each new block's logs for every watched address, in ranges, re-checking the last 100 blocks for reorganizations.
03
Detect
Versioned rules turn events into findings, with the transaction, the block, the actor and the values before and after.
04
Confirm
Most alerts wait 20 blocks, about 2 seconds. A critical one can go out at once, marked pending.
05
Deliver
Once per transaction, to each channel the watch chose, and retried with backoff if it fails.
06
Record
Each contract's findings join its public record, so anyone can check what changed and when.

The rules

14 rules, each one versioned.

A published rule never changes: a fix is a new version, so an old alert still says what its rule meant at the time. The thresholds here are the defaults, and each watch can set its own.

Wallets too

Watch a treasury, not just a contract.

Follow a deployer or treasury wallet, and hear when it moves a large share of a token, gives an approval it may regret, or puts out something new.

A transfer out of 1% or more of a token's supply
An unlimited approval, or one of 5% or more of a supply
A new contract that names the wallet as its owner or first holder

A wallet's alerts are yours alone. They never appear in the public feed or record, which only covers contracts.

Channels

Five ways to hear it.

Each watch picks its own channels, the lowest severity worth a ping, and quiet hours that let only critical alerts through.

ChannelNotifications

In the browser or on a phone, even with VIGIL closed. On an iPhone, add VIGIL to the home screen first.

ChannelWebhooks

Signed with a secret for each endpoint, retried with backoff, and checked in one call with the SDK.

ChannelEmail

Each alert as it happens, or one digest a day. The address is confirmed before anything is sent.

ChannelTelegram

Open a link from Settings and press Start. Alerts then arrive in that chat or group, from VIGIL's own bot.

ChannelDiscord

Paste a channel's webhook URL. There is no bot to install, and nothing in an alert can ping anyone.

How it behaves

Facts, fast, and quiet.

Four things every alert keeps to, whichever way it reaches you.

Facts only

Every alert comes from a real onchain event, with its transaction, block, actor and rule. VIGIL says what happened. It never accuses anyone.

Fast, and corrected if wrong

Alerts arrive seconds after a block. If a reorg removes the event, you are told that too.

Quiet by design

One alert per transaction, your own thresholds, quiet hours, and cooldowns on noisy rules.

Built to be built on

Signed webhooks with retries, so your own systems can react: notify, pause, block or ignore.

Robinhood Chain

Built on the chain it watches.

Robinhood Chain is a permissionless, EVM-compatible Layer 2. VIGIL reads its public logs as blocks arrive, and keeps a public record of every change it finds to the contracts people watch.

VIGIL is not the chain. Robinhood Chain is the network; VIGIL watches what that network makes public.

For integrations

Act on it in your own systems.

Webhooks are signed, retried, and arrive at least once. Check one with the TypeScript SDK before you act on it: notify, pause, block or ignore.

Questions

Before you start.

The short answers. The docs have the long ones. Read the docs ↗

Is VIGIL free?

Yes, for up to three watches, with every rule and every channel. The Pro plan raises the number of watches.

Does VIGIL need my private key?

No. You sign in by signing a message with your wallet. It sends no transaction, costs nothing, and VIGIL never asks for a key.

How fast is an alert?

Seconds after the block. Most alerts wait 20 blocks, about 2 seconds, so a reorganization cannot take them back. A critical one can go out at once, marked pending.

What if the chain reorganizes?

VIGIL re-checks recent blocks on every scan. If an event disappears, its finding is retracted, and every channel that had the alert is told.

Can I watch a wallet, not a contract?

Yes: large transfers out, large or unlimited approvals, and new contracts it deploys. A wallet's alerts are yours alone: they never appear in the public feed or record.

What if an alert is wrong?

Report it from its page. A person reviews every report, and a rule at fault is fixed with a new version, never edited in place.

Does VIGIL say who is to blame?

No. It reports what happened onchain and how severe that kind of change usually is. It does not judge intent.

Can my own systems act on it?

Yes: signed webhooks, an API with keys of your own, and a TypeScript SDK that checks every webhook's signature.
