BNB Smart Chain

eth_getStorageAt

A contract on BNB Smart Chain keeps its state in 32-byte slots. eth_getStorageAt reads one of those slots directly. No ABI and no getter function required. You supply the contract address plus the slot index and a block tag, and the method returns the raw 32-byte word found there, zero-padded on the left. Since BNB Smart Chain is a geth-equivalent EVM funded by BNB, the slot layout matches what any Solidity compiler would produce. Send the call to https://bsc.therpc.io/YOUR_API_KEY on chain ID 56 when you need to peek at storage the contract never exposes publicly.

Use cases

• Resolve a proxy's logic address straight from the EIP-1967 implementation slot even when no getter is exposed.
• Read DAO governance internals such as proposal state or tallied vote counts that the contract leaves unexported.
• Confirm a deployed contract's storage layout matches the source during a BSC security audit or upgrade review.
• Track down a misbehaving contract by dumping the raw slot values behind its unexpected on-chain behaviour.

Errors & troubleshooting

Common pitfalls

• The ABI says nothing about where each variable lives. You have to compute the slot index for whatever field you want to read, or look it up.
• Several small variables can be packed into one 32-byte word. To pull out an individual field you then have to mask the returned value and shift it.
• A mapping entry does not sit at its declared base slot — it resides at keccak256(abi.encode(key, baseSlot)), which you must hash before querying.
