Solana

This page lists what Farbeam reads on Solana. Live values are on the Solana data page. The API returns the same facts from Get a chain.

#What is indexed

Two reads feed the Solana rows. Both look for balance changes of the tokens below and native SOL, at $100,000 or more. All rows carry sampled: true. This is not a complete index.

#Curated tokens

The curated tokens page explains the list and its prices.

#Sources

#Measured values

These figures are a snapshot from the API at 2026-11-04T19:33:40.040Z UTC. They are examples, and they change on every poll. They are not targets.

#Quirks

• Sampled. About 1 slot in 148 was read in the measurement above. Read sampling first. A wallet alert on Solana will miss nearly everything, except partial coverage of the 7 watched exchange wallets.
• No chain id. chain_id is null, and family is svm. In Wallet overview, family reads solana. Handle both spellings.
• Balance changes, not logs. The poller compares pre and post balances. from is the owner with the largest decrease, and to is the owner with the largest increase. amount is the smaller of the two, so a transaction with many parties reduces to one pair.
• SOL and wSOL can double up. One transaction can produce both rows. Group by tx before you sum.
• Different fee fields. base_fee_gwei, gas_price_gwei and gas_used_ratio are null. priority_fee_microlamports is the 75th percentile of getRecentPrioritizationFees, and tps comes from getRecentPerformanceSamples.
• Addresses are case sensitive. They are stored as base58, and they are not lowercased. Beamline string comparison still ignores case.
• **Holder checks can read unknown.** getTokenLargestAccounts fails on some large tokens at the RPC, so the top10 check reads unknown. This happened for USDC and wSOL on 2026-11-04 UTC.
• Daily budget for the keyed RPC. The service limits its own Helius use per UTC day, and background work may use half. keyed_rpc_daily_limit_reached in Status reads true when the budget is spent. Lookups then use the public endpoint.
• Helius and fallback. With Helius, wallet token lists use getAssetsByOwner (token_source: helius-das). On fallback they use getTokenAccountsByOwner, which reads the classic SPL Token program only.

#Try it

curl -s "https://farbeamlabs.com/api/v1/chains/solana"

const res = await fetch("https://farbeamlabs.com/api/v1/chains/solana");
const { data } = await res.json();
console.log(data.status.status, data.status.head, data.tokens.length);

import requests

data = requests.get("https://farbeamlabs.com/api/v1/chains/solana", timeout=30).json()["data"]
print(data["status"]["status"], data["status"]["head"], len(data["tokens"]))

A rule for this chain, from the Beamline examples style: chain == "solana" and token == "USDC" and usd >= 500k.
