How this service works
Treasury snapshot: the native ETH balance and every ERC-20 balance of an address at a block (or now), read on-chain, with the block time. Use it to check treasury, runway or backing claims pinned to a block. Ethereum, Base and Robinhood Chain. Independent, by Blockpin; not a Claus Network service.
Output
Returns a structured object containing the block number, block timestamp, native ETH balance, an array of ERC-20 token balances (contract address, symbol, decimals, raw and formatted amounts), and a plain-language summary of the treasury holdings at the specified block.
Example use cases
DAO Treasury Audit at Vote Block
“Pull a treasury snapshot for 0x4F2083f5fBede34C2714aFfb3105539775f7FE64 on Base at block 12500000 — I need to see the ETH and all token balances they held when the governance vote passed.”
Protocol Backing Claim Verification
“Verify the backing claim for this protocol: they say their treasury at 0x9008D19f58AAbD9eD0D60971565AA8510560ab41 on Ethereum held at least 5000 ETH and 2M USDC at block 18500000 — can you pull that snapshot and check?”
DeFi Fund Runway Check
“Check the current treasury balance of 0xBA12222222228d8Ba445958a75a0704d566BF2C8 on Ethereum right now — I need to see all ERC-20 tokens and native ETH so I can estimate their runway.”
Technical details
Endpoint
GEThttps://check.blockpin.dev/treasury?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a precise, block-pinned snapshot of both native ETH and all ERC-20 token balances for a single address on Ethereum, Base, or Robinhood Chain. Prefer it over general block explorers when you need machine-readable multi-asset treasury data tied to a specific block for audit, verification, or runway analysis purposes. It is especially suited for verifying backing or reserve claims that reference a specific block number.
Side effects
- Block too old for non-archive node — archive state required for historical blocks, may be refused before payment
- Invalid address format — must be a valid 0x-prefixed 40-character hex address
- Unsupported chain — only ethereum, base, and robinhood are valid chain values
- Too many token addresses — maximum 10 token addresses allowed in the tokens parameter
- Block not yet mined — requested block number is in the future
- Rate limiting or payment failure — x402 payment of $0.01 USDC required per call
