Sources & methodology
Where the figures come from, how they’re calculated, and what they leave out.
Reserve funding
The dashboard shows the daily USD value of LINK sent from Payment Abstraction to the Chainlink Reserve, as reported by DefiLlama. These are gross deposits along one payment path. They do not measure the reserve’s balance, net growth after withdrawals, or income distributed to holders.
The cumulative chart adds deposits within the selected period. Its rise alone does not show that funding is accelerating. The research page separately shows sampled deposits in LINK, measured from token transfers rather than estimated using today’s price.
Request fees and aggregator receipts
Oracle request fees are recorded LINK payments, valued in USD, from six chains: Ethereum, BNB Chain, Polygon, OP Mainnet, Arbitrum and Avalanche. This covers one type of oracle request event, not all Data Feeds, CCIP or enterprise activity.
Fee aggregator receipts are tokens received by the fee aggregator, valued in USD. Receipts can be batched, so payment dates may differ from service usage dates.
Aggregator receipts and reserve deposits can represent different stages of the same payment. Adding them would risk double counting. Their ratio is not a conversion rate: timing, prices, routing and other transfers can create differences, and individual transactions have not been matched.
Circulating supply
Circulating supply comes from Chainlink. The maximum supply is one billion LINK. Chainlink publishes a current figure without an observation time or historical series, so our history begins with the first daily reading collected by this site.
Changes between consecutive daily readings do not identify exact release times or prove that tokens were sold. Missing days remain gaps. Staking and reserve holdings are not subtracted from the published figure to estimate tradable supply.
Weekly funding comparisons
Reserve deposits often arrive in batches. In the initial 90-day sample, 13 days had deposits, with a median seven-day interval. This describes that sample, not a guaranteed weekly schedule.
Weekly charts use complete Monday–Sunday UTC weeks. The 4W, 13W and 52W periods end on the latest complete Sunday. Headline totals compare the selected period with the same number of preceding weeks. The funding-pace card always compares the latest four complete weeks with the preceding four.
A missing daily value makes the week and its period total unavailable. The four-week average needs four consecutive complete weekly values. “All” starts at the later first observation shared by the request-fee and reserve-funding series. Deposit timing and LINK’s dollar price can affect funding trends.
What’s missing
These datasets do not cover all Chainlink revenue, recurring customer activity, a complete reserve balance history, historical supply releases, staking balances or the share of rewards funded by fees. Public transfers do not fully disclose private enterprise revenue or identify the customer behind each payment.
The GHO chart covers transfers involving one Ethereum CCIP pool. It does not measure all CCIP activity, fees or successful delivery on other chains. Wallet charts follow a selected group of addresses; exchange and contract balances may belong to many people.
Partnership announcements do not establish live usage. GitHub merges, software releases and verified deployment are separate milestones. Research pages distinguish what has been observed from what remains unverified.
Data dates and updates
Dashboard data is checked when someone visits more than six hours after the previous check. “Refresh data” requests an update, available once every ten minutes across all visitors. An unsuccessful update keeps the last available figures and shows a warning. Research charts and analysis update separately and display their own dates.
The collection time and source observation time can differ. Flow charts exclude today’s partial UTC day; weekly charts exclude incomplete weeks. Missing observations are not zeros. A reported zero means the provider supplied zero, not that every possible activity has been ruled out.
Dashboard data is marked overdue if collection or the latest available source observation is more than 48 hours old; price is marked overdue one hour after its source observation. A source failure also triggers a warning. LINK price is a point-in-time quote from DefiLlama, not a live price feed.
