Coingecko
Coingecko is a crypto price aggregator and portfolio tracker
Coingecko is a price board and holdings notebook for cryptoassets, technically an independent market-data aggregator. It collects trading-pair data from centralized exchanges and decentralized markets, filters anomalous inputs, calculates volume-weighted prices, and displays market capitalization, supply, volume, charts, exchange-quality signals, and manually entered portfolio performance. The service supplies information rather than executing trades or holding coins.

In short: An aggregate price needs closer inspection when liquidity is thin, data is stale, or the contract address identifies another asset.
Trust Score and on-chain coverage now sharpen the headline price
Trust Score supplies context about the markets behind an aggregate price. Coingecko pairs its market data with spot-exchange scores on a 1-to-10 scale, plus trading-pair indicators based on liquidity, activity, spread, and order-book depth within ±2% of the quoted price.
Introduced in 2019, Trust Score received its Basilisk revision in May 2026. The revised method emphasizes direct trading volume, order-book depth, verified regulation, proof of reserves, and operational history. It also grades exchanges relative to their peers. The score remains a comparative quality signal; it is neither an account balance nor an executable quote.
GeckoTerminal adds decentralized-exchange pool data from networks including Ethereum, Solana, and Base. That matters when a token trades through an automated market maker before broad centralized-exchange coverage develops. A hosted Model Context Protocol interface also exposes structured data to compatible AI assistants. These additions widen access, while asset identity remains the first dependency.
One ticker can point to several different assets
Token identity determines whether a displayed price belongs to the asset a reader intended to inspect. A ticker such as USDC is useful shorthand, yet the network, issuer, and contract address distinguish native Circle-issued USDC from bridged representations. WETH is likewise an ERC-20 representation of ETH rather than the native gas asset.
Ethereum Virtual Machine addresses are 20 bytes and appear as 40 hexadecimal characters after the 0x prefix. EIP-55 adds mixed-case checksum information without changing those 40 characters. Solana accounts use 32-byte public keys. One SOL contains 1 billion lamports, while a Solana transaction has a fixed maximum size of 1,232 bytes. These differences explain why chain context cannot be collapsed into a ticker alone.
| Identifier | What it resolves | Hard limit or threshold |
|---|---|---|
| Platform ID | One listed database record | The exact unique ID is required |
| Ticker symbol | Human-readable market shorthand | No uniqueness requirement exists |
| Contract address and network | A specific token deployment | 20 bytes on EVM chains; 32 bytes on Solana |
Contract-address search is the strongest match for smart-contract tokens. The network label must agree as well. The same symbol can describe separate issuers, wrappers, vault receipts, or bridge mechanisms, each with different liquidity and supply data. Once the identity is fixed, the price pipeline becomes meaningful.
Exchange inputs become one market price through filtering
Coingecko calculates an aggregate price from exchange tickers rather than copying one venue's last trade. For each asset, the initial aggregation set includes up to the top 600 tickers by volume. Eligible tickers are converted into a common BTC-based reference, screened for anomalies, and combined through a volume-weighted average price.
Assets with fewer than 3 tickers receive a specific discontinuity check: a ticker change greater than 100 times its previous price is treated as an outlier. With 3 or more tickers, median absolute deviation establishes the filtering bounds. Exchange-volume calculations also exclude pairs that have remained inactive for more than 3 hours. The published 24-hour volume therefore reflects filtered, active inputs rather than every submitted number.
A displayed average remains separate from the price available for a particular order. Coinbase and Kraken maintain venue-specific order books. Uniswap derives its quote from pool reserves and the selected route. Order size, spread, pool liquidity, and network fees determine actual execution.
Market capitalization then multiplies the aggregate price by verified circulating supply. Fully diluted valuation uses maximum supply where that field exists. Bitcoin has a fixed ceiling of 21 million BTC, whereas Ethereum has no protocol-defined maximum supply. Missing or disputed supply data therefore changes which valuation fields the platform displays.
Portfolio entries turn market data into a personal ledger
The portfolio tracker combines manually entered transactions with aggregate market prices to estimate holdings, cost basis, and profit or loss. Saved watchlists organize assets without recording quantities, while multiple portfolios separate strategies, accounts, or research groups (covered in Coingecko step by step ).
Unit precision matters when transaction data is entered. One BTC equals 100 million satoshis, 1 ETH equals 10 18 wei, and 1 SOL equals 1 billion lamports. Rounding a small balance too early distorts both cost basis and percentage returns. A 24-hour percentage describes a rolling market window; it does not measure performance since the portfolio purchase.
Manual records create a clear operational boundary. Every purchase, disposal, fee, and transfer needs the correct quantity and date. Recording a transfer between personal wallets as a sale changes the calculated return even though economic exposure stayed intact. The tracker holds no private keys, settles no transaction, and provides no deposit address. Portfolio values remain informational calculations built from the entries supplied.
Start with the exact asset, then widen the view
Asset search works best when identity is settled before performance is compared. Coingecko search accepts names and symbols, while a contract address provides the tighter match for tokens deployed on a named chain.
- Search the full asset name or paste its contract address.
- Confirm the network, issuer, and native or non-native classification.
- Compare price with circulating, total, and maximum supply fields.
- Open the markets view and inspect venue liquidity and Trust Score.
- Add the asset to a watchlist or record a portfolio transaction.
Browsing market pages requires no saved portfolio. An account becomes useful when watchlists, holdings, alerts, or Candy rewards need to persist across the web interface and mobile apps. The selected quote currency and time window should stay consistent when comparing assets.
Automation belongs in the adjacent API workflow. The keyless public route uses dynamic IP-based throttling, while authenticated plans enforce account-specific allowances. On those plans, each successful HTTP 200 request deducts 1 monthly call credit. Every attempt, including 4xx and 5xx responses, counts toward the per-minute limit. That distinction separates monthly consumption from short-window capacity.
A 2014 data project now competes on research depth
In the same way, Coingecko launched on April 8, 2014, under founders TM Lee and Bobby Ong. Its free public API opened in May 2018 with more than 20 endpoints at launch. The iOS and Android apps followed in July 2018, Trust Score arrived in May 2019, Candy launched in June 2020, and the portfolio feature appeared in August 2020.
The broad market-data role overlaps with several established tools, but each alternative answers a different question. CoinMarketCap offers another global ranking and watchlist system. TradingView emphasizes advanced charts, indicators, and venue-specific feeds. DefiLlama focuses on protocol-level total value locked, fees, revenue, and stablecoin data. Etherscan exposes Ethereum transactions, contracts, token balances, and event logs at address level.
The right source follows the decision. Aggregate prices, supply comparisons, exchange context, and manual portfolio monitoring fit this platform's strengths. A transaction-level question belongs with a block explorer. An execution decision belongs with the exchange or decentralized pool handling the order. This separation keeps market summaries, ledger facts, and executable quotes from being mistaken for the same output.
Practical questions about Coingecko
Does Coingecko charge projects a listing fee?
Token and exchange listing submissions are free. A payment or donation does not secure approval or shorten review. A cryptoasset needs a working project site and block explorer, clear supply information, and active trading on at least one exchange already integrated with the platform. Meeting those prerequisites starts an evaluation; it does not create an automatic right to a listing.
How long does a new token listing review take?
Coingecko does not promise a fixed token-listing turnaround. If an application remains unlisted after 2 weeks, the project likely did not pass evaluation. Liquidity, project maturity, complete disclosures, functional market data, and naming conflicts affect the decision. Submitting the same request repeatedly does not accelerate the review and can interfere with orderly processing.
Can portfolio transactions be exported as a CSV file?
Portfolio transactions cannot currently be downloaded or exported as a CSV file. The feature functions as a personal tracker inside the web and mobile interfaces, where it stores entered holdings, transaction history, and performance calculations. Anyone needing portable accounting records should retain the underlying transaction data separately rather than treating the portfolio tracker as the only ledger.
Will a shared watchlist reveal my holdings and profit?
A shared public watchlist shows the selected assets, while holdings and profit-and-loss figures remain hidden by default. The owner must first make the portfolio public and can return it to private status later. The feature shares research selections rather than wallet balances, private keys, or transfer authority, though the chosen visibility setting still deserves a check before sharing.
What happens if circulating supply cannot be verified?
An unverified circulating supply is displayed as a dash rather than a confirmed figure. Standard market capitalization requires both price and circulating supply, so the platform does not substitute a speculative supply value. Price, total supply, or maximum supply data might still appear when those fields have adequate support, leaving readers to distinguish available market data from an incomplete valuation.
How frequently can I claim Coingecko Candies?
A new Candy claim becomes available on a 24-hour cycle. Candies are loyalty points attached to an account and are redeemable for selected rewards under the program's terms. They are not an official Coingecko cryptocurrency, and reward availability changes as offers are added or removed. Missing a claim interrupts collection for that period rather than creating an on-chain balance.
Could a token appear on GeckoTerminal before Coingecko lists it?
A token can appear on GeckoTerminal when an indexed decentralized exchange provides usable pool and on-chain trading data. That pool record does not equal acceptance into the main Coingecko asset directory. The main listing process applies separate identity, market, liquidity, and project-information checks, while GeckoTerminal follows contracts and pools visible through supported blockchain networks.
