Proof of Reputation · Pseudonymous by default

Know the wallet before you trust it.

Wallet history, economic relationships, and attestations become trust evidence — no real name required. Every score opens into the evidence behind it.

The score is not the product. The evidence is.

Every number Fathom shows compresses a set of on-chain proofs. Open any score and you get the walkthrough: what went in, what was measured, and what it contributed.

Wallet history

Age, lifespan, and activity patterns from the wallet's indexed past.

Economic history

Flows, volumes, and transaction patterns across the full walk.

economic proofs

Relationships

Counterparty graph: unique wallets, repeat interactions, longevity.

counterparty proofs

Attestations

Vouches, role attestations, and disputes signed by other wallets.

social proofs

Who economically interacts with this wallet?

Relationships carry more signal than raw balances. The graph reads real transfers, vouches, and attestations — edge weight is interaction count, purple nodes are vouchers, accent rings are attesters. Drag nodes, zoom, and click legend entries to filter.

From raw chain data to a decision you can defend.

Four deterministic steps. No black box in the middle — every stage is inspectable on the profile.

Step 1

Search

Paste any address. No account, no connection, no permission needed.

Step 2

Extract proofs

The indexer walks the chain and normalizes raw history into proofs.

Risk is evidence too.

Fathom does not hide uncomfortable signals. Risk flags, disputes, and attestations are shown as structured, inspectable objects.

A flag is the start of an inspection, not a verdict. Open the signal to see which wallets cluster and why.

Dispute stateopen

Unfulfilled OTC trade

Evidence: Settlement never arrived on-chain
Reporter: 0x9d3f…b2c1
Filed: 18 days ago

A dispute is a signed claim by another wallet — weigh it against the full evidence, not as proof of wrongdoing.

Attestationsigned

OTC counterparty

Relationship: 13 trades · 11 months
Attested by: 0x71c4…4a3f
Weight: Stake-weighted · capped

Attestations are signed on-chain with skin in the game — vouch stake is slashed when a claim breaks.

Product first. Protocol underneath.

Everything the product shows is reachable over a plain read-only API. No key, no SDK lock-in, no hidden endpoints.

Fair questions, straight answers.

Is the score proof that a wallet is honest?

No. The score is a deterministic compression of available on-chain evidence — a starting point for inspection, not a verdict. Two wallets with the same score can have very different histories behind it. Always read the evidence before you decide.

Can vouches be farmed?

Attempts exist, which is why vouches are stake-weighted, capped, and monitored for concentration. A vouch carries stake that can be slashed when a claim breaks, and clustered vouching shows up as a risk signal instead of silently inflating a score.

Isn't a large balance already proof of trustworthiness?

No. Money is not trust. A wallet can be rich and freshly farmed, or modest and battle-tested across years of counterparties. Fathom scores behavior — age, repeat relationships, kept agreements — not wealth.

Do I need to connect my wallet to inspect someone?

No. Public inspection requires nothing but an address — no connection, no account, no permission. Connecting is only needed to claim your own profile or to sign vouches and attestations.
