Crypto Infrastructure Map
The layer number is the easy part. Shared control is the part that breaks things.
The top three networks hold 84.1% of tracked stablecoin stock, while keys and permissions account for 34.9% of known one-year incident loss.
Five labels. One real question.
Where can one failure stop money, pricing, withdrawals or settlement? The stack below translates the labels without pretending that L3 and L4 have one industry-wide meaning.
L0 · Connection and coordination
Moves messages or security between networks. If the same group of computers approves several networks, one failure can reach all of them.
L1 · Base settlement
The network that records the final state. Stablecoins and apps can cluster here even when users enter elsewhere.
L2 · Cheaper execution
Bundles activity and settles back to a base chain. The official transfer route and the operator that orders transactions can matter more than the layer number.
L3 · Application chains
A network built for one product or group. This label is not used consistently, so compare the actual control path.
L4 · Apps, wallets and access
Where users trade, borrow and sign. It is not a formal blockchain layer, but failures here can still block access.
The contrarian read · Layer labels are not risk scores
Two products on different layers may share the same custodian, bridge, key holder or price source.
The layer number tells you where something sits. It does not tell you who can pause it, upgrade it or restore it.
Capital can gather at different points
Each bar shows the largest provider inside its own group. The groups overlap, so their dollar totals are not added together.
Polygon Bridge · 86.6% is the highest leader share on this screen. It tells us where a failure could have a large reach. It does not say that a failure is likely.
Where the digital dollars sit
This is the stock of tracked stablecoins on each network. It is not daily trading and it is not money owned by the chain.
Remove Ethereum, and Tron holds 59.6% of what remains. Concentration does not disappear; it changes address.
The failure record points sideways
Known losses do not line up neatly by layer. Keys, permissions, bridges, prices and websites can cut across the full stack.
Known loss · one year
$2.1bn across 301 records with a loss amount.
Keys and permissions
34.9% of known loss came from access-control or private-key failures.
Bridge losses
36.3% of known loss was marked as bridge or cross-chain.
The deepest risk often runs across the diagram, not down one numbered layer.
What actually broke?
These are known loss amounts grouped by the failure named in the incident record. Missing amounts remain missing.
The three largest failure types account for 70.3% of known loss. A long list of smaller categories should not hide where most of the money went.
Losses arrive in lumps
Monthly known loss over the last year. A quiet month does not mean the system became safe; one large event can redraw the year.
The latest quarter contains 40.3% of the one-year known loss. Timing changes the story, so the page keeps the full twelve-month strip visible.
The latest recorded breaks
Recent events are shown with the stated loss. “Not reported” is kept separate from zero.

Only 5 records in the one-year window state returned funds. The known returned amount is $1.9mn, or 0.1% of known loss. That is incomplete reporting, not a recovery rate for the whole market.
