Open blockchain datasets from Bit Primitive, with full schemas, sources, licences and update schedules. Free to download as Parquet or CSV.
- Base ERC-20 transfers (100-block sample): Every ERC-20 Transfer event in 100 consecutive Base mainnet blocks, decoded, with each token's symbol, name and decimals joined in.
- Bitcoin transaction outputs (3-block sample): Every output of every transaction in 3 consecutive Bitcoin blocks: who received how much, the output's script type, and the sender when every input came from a single address. OP_RETURN and other outputs without an address are kept, with no address.
- ERC-20 token directory (Ethereum and Base): Every ERC-20 contract seen in the Ethereum and Base transfer samples, with the name, symbol and decimals it reports and how many transfers it had. Useful for decoding amounts.
- Ethereum ERC-20 transfers (200-block sample): Every ERC-20 Transfer event in 200 consecutive Ethereum mainnet blocks, decoded, with each token's symbol, name and decimals joined in. A sample of what chainstar produces from a single command.
- Ethereum transaction fees (200-block sample): The execution fee of every transaction in the same 200 Ethereum blocks: gas used, the price paid and the base fee, in wei and in ETH. Blob fees are not included.
- Solana DEX swaps (300-slot sample): Every swap in 300 consecutive Solana slots through Raydium, Orca Whirlpool, Meteora DLMM, Jupiter, Pump.fun or PumpSwap: what the signer gave and got, with a USD value from prices derived from the same on-chain swaps.
- Solana token and SOL transfers (20-slot sample): Every SPL, Token-2022 and native SOL transfer in the successful transactions of 20 consecutive Solana slots, inner instructions included, with each mint's standard and decimals.
- Solana token prices from on-chain swaps (300-slot sample): Hourly and daily USD prices for every Solana mint traded in the same 300 slots, derived only from on-chain swaps against USD stablecoins and SOL: outliers rejected, each price with its method, observations, volume and confidence. Low-confidence prices are left NULL, with the observed median kept.
