beaconcha.in
Ethereum beacon chain explorer for validators, epochs, blocks, ERC-20 balances, network performance, and deposit events.
Good for Ethereum analytics that pull validator and epoch metrics, execution block details, ETH.Store returns, and chart visualizations of network health.
Example Use Cases
These are the beaconcha.in actions Snow can use when building apps with you. Connecting an account does not make Snow run these on its own.
Retrieve aggregate metrics and status for a beacon chain epoch. Use this tool to fetch epoch-level statistics including validator counts, balances, participation rates, block counts, and various operations (slashings, deposits, exits). Supports lookup by epoch number or keywords 'latest' or 'finalized'.
Retrieve a paginated list of ERC-20 token balances for a specific Ethereum address. Use offset and limit query parameters for pagination. Returns token contract address, balance in token units, and token symbol for each ERC-20 token held by the address.
Retrieve one or more execution-layer blocks by block number from the Ethereum Beacon Chain. Use this tool to look up execution block details including block hash, timestamp, rewards, gas usage, transaction counts, and consensus information. Supports querying up to 100 blocks in a single request by providing block numbers as a comma-separated list. Returns an array of execution block data. If a requested block number is not found, it will be omitted from the results.
Retrieve the latest known Ethereum Beacon Chain network state. Returns current slot, epoch numbers, finalized epoch, finality delay indicator, syncing status, and ETH/USD price along with multi-currency conversion rates. Use this to check current network status and get real-time ETH pricing data.
Retrieve aggregated network performance metrics for the Ethereum Beacon Chain. Use this to analyze validator performance across attestations, proposals, and sync committee duties over a specified time window. Returns beacon scores, duty statistics, and finality information.
Retrieve detailed information about an Ethereum Beacon Chain slot. Use this tool to look up slot details including attestations, slashing counts, block roots, execution payload data, validator proposer, graffiti, and sync aggregate information. Supports lookup by slot number, 'latest'/'head' keywords, or block root hash. Returns comprehensive slot data including: attestation count, block roots, epoch info, execution layer details (gas, fees, transactions), proposer info, and withdrawal count.
Retrieve attestations observed for one or more validators within a bounded epoch window. By default, returns data for the last 100 epochs. Use when you need to check validator attestation history, verify attestation performance, or analyze missed attestations.
Retrieve per-epoch balance history for one or more Ethereum Beacon Chain validators. Use optional query parameters to control the time window (latest_epoch, offset, limit). Returns an array of balance snapshots showing how validator balances changed over time, including both total balance and effective balance. Useful for tracking validator performance and generating historical balance charts.
Retrieve consensus-layer rewards for one or more validators over multiple lookback windows. Returns reward totals for the last 1, 7, 31, and 365 days, plus cumulative totals when available. All amounts are returned in gwei. Supports lookup by validator index or BLS public key.
Retrieve per-day statistics for a single Ethereum Beacon Chain validator by index. Returns daily balance snapshots (start/end/min/max), duty counts (proposed/missed blocks, attestations), and deposit/withdrawal activity. Use this tool to analyze validator performance over time, track balance changes, and identify issues like missed duties or slashing events. Supports filtering by day range using `start_day` and `end_day` parameters.
