Arbitrum Transfers

One Parquet table with 24 columns: every native ETH and token transfer on Arbitrum, one row each, with the amount, the token's details, the transaction it settled in and the fee. ETH moved by contracts in internal calls is included, and so are NFTs.

About 4.9 billion rows over 50 months, roughly 570 GB as Parquet, estimated from the sample files. The last 24 months hold about 3.0 billion rows and the last 12 months about 1.3 billion. Row counts come from the live table; exact figures arrive with the delivery manifest.

To the start of indexed history: from 31 August 2022, the Nitro upgrade, at block 22,207,820. The chain's earlier history, Arbitrum Classic, is not in our index. The Full window runs from there to yesterday.

The export applies no filter of its own: spam tokens, lookalike tokens, zero-value rows and failed transactions all stay in, and the columns let you drop them. Arbitrum Classic, the history before the Nitro upgrade, is not in our index. The Nitro genesis carried every Classic balance across with no transfer, so balances rebuilt from these rows alone will not match for any address or token that existed before Nitro.

Arbitrum has no price history of its own, so ETH, WETH, USDC, the bridged USDC.e, USDT and DAI are valued on Ethereum's series: bridged ETH is ETH, and using the real series keeps a de-peg visible. Other tokens, including WBTC, LINK and ARB, carry 0. In the linked sample file 73% of rows are priced; across all three sample files it is about 80%. A value of 0 means either a $0 transfer or no price; the column cannot tell them apart.

Decoded from Arbitrum by our own indexer, which reads token transfer events and traces internal calls for ETH. Before release we read the sample back: 329 rows over blocks 508,435,000 to 508,435,049, every amount carrying exactly its token's decimals. The live table returns the same 329 rows for those blocks.

The amount column is decimal adjusted. Multiply it by 10 to the power of the token's decimals for the raw on-chain integer. We ship the adjusted value because decimals differ per token and the raw figure is wrong without them.

Amounts are decimal strings, so casting to float loses precision on large values. Symbols and names repeat, and lookalike tokens copy them, so join on the contract address. Failed transactions are kept; filter TransactionStatus_Success for settled flow. Zero-value rows, 1.8% of the sample, move nothing, so drop them before counting activity. Transaction_Type includes Arbitrum's own system types, numbered 100 to 106, alongside the standard 0, 1, 2 and 4.

Filter Transfer_Currency_SmartContract to the token's contract, lower case with 0x. For native ETH alone, filter Transfer_Currency_Native to true; its contract column holds the string 0x.

One line in DuckDB: SELECT * FROM read_parquet('transfers/*.parquet') LIMIT 10. Pandas works too: pandas.read_parquet(path). The sample file opens without credentials.

Refreshed daily with T+1 latency, so a purchase made today includes everything to yesterday. Delivered as Parquet named by block range, 50 blocks per file and sorted ascending, under a stable layout with a JSON manifest listing every file and its sha256. We prepare the files within 7 business days of purchase and email you the location. You choose at checkout where to collect them: a Requester Pays S3 bucket, downloaded with your own AWS account, or a Cloudflare R2 bucket with a read-only API key and no egress fees. Files stay available for 7 days from delivery. Enterprise orders can be delivered into your own S3, GCS or R2 bucket.
