About Farbeam
Farbeam is an on-chain data and analytics service. It reads public blockchains and public data sources, stores a narrow index of large transfers, and publishes the results through an API, browser tools and research notes. It covers Ethereum, Base, BNB Chain, Arbitrum One, OP Mainnet, Polygon PoS and Solana.
The site makes no buy or sell calls. Nothing on it is financial advice.
#What it reads
| Source type | Used for | Named sources |
|---|---|---|
| Public JSON-RPC | Chain heads, fees, logs, balances, transactions, Solana mints | dRPC, 1RPC, Nodies, BlockRazor, Arbitrum, PublicNode, Helius |
| Prices | USD value of transfers and balances | CoinGecko |
| Pool data | Liquidity, volume, pool age | DexScreener, GeckoTerminal |
| Contract and authority fields | Token checks | GoPlus, RugCheck, direct RPC |
| Market context | TVL, stablecoin supply, DEX volume | DefiLlama |
| Hand-curated list | Address labels | 54 public addresses in the code on 2026-11-04 |
The full list with cache times is on data sources. If any of these sources stops answering, the matching feature degrades, and the status page shows which source failed.
#How it decides what to publish
Farbeam has few editorial decisions, and they are written down as code and thresholds.
| Decision | Rule | Reason |
|---|---|---|
| Which transfers are stored | USD value of $100,000 or more | The set stays small enough for one SQLite file over 7 days |
| Which tokens are indexed | A curated list of major assets per chain, on the curated tokens page | A price and correct decimals are known for each one |
| Which chains are indexed | Ethereum, Base, BNB Chain and Arbitrum, plus partial Solana coverage | OP Mainnet and Polygon have head and lookup data only |
| Which addresses get a label | A public, well-known address added by hand | No clustering, so no inferred labels |
| What a token check says | Fixed thresholds on token checks | The same input gets the same result |
| What a research note says | Only numbers from API calls, with the call and UTC time shown | A reader can run the call again |
#Rules
These rules apply to every page and endpoint.
#Unknown is not a pass
If a source does not return a field, the check reads unknown. It does not count as pass. Reports do not produce a composite score, because a score would hide the missing data. A token report with 6 unknown checks shows 6 unknown checks.
#Sources are named
Every token check has a source and a field. Market responses have meta.source. Research notes show the exact API call. If a number cannot be traced to a call, it does not go on the site.
#No calls
Farbeam does not say whether to buy, sell or hold anything. It publishes no price targets and no token recommendations. A trending list is a description of what an aggregator ranked, and a passing check is a statement about one field. Neither one is a signal.
#Limits are stated
Coverage limits appear next to the data. Solana events carry sampled: true. EVM wallet balances say they are not a full portfolio. The platform page lists where the index skips blocks.
#Sample data is marked
When a page shows an example that is not real data, it says so. Earlier pages of this site showed sample screens and described features that were not yet built. Those pages were replaced, and the changelog records it.
#Dates
The site was first published as a static site on 2026-11-03. The real backend, tools and documentation went live with this rebuild on 2026-11-04. There is no longer history than that.
#Not built
There is no wallet clustering, attribution graph or flow graph tool. There are no paid plans, team accounts, SSO, official SDK packages, data exports, or history beyond 7 days. Email delivery and EVM wallet sign-in do not exist. All of these are Planned, with no dates. The roadmap has the list.
