debug_storageRangeAt

Last updated:

debug_storageRangeAt reads the storage trie of a single contract and returns a range (page) of its slots, reconstructed at the state that existed after a chosen transaction in a chosen block. Each entry is a preimage key and its 32-byte value, indexed by the hash of the slot key. Because storage is a large keyed map, the method is paginated: you give it a starting key and a maximum count, and it returns the slots from that point plus a nextKey cursor to continue from.

Use this when you need to inspect or snapshot raw contract state at a precise point in history — for example to audit a storage layout, diff a contract's slots across two transactions, or recover a value that is not exposed through a view function. Unlike a single-slot read, it walks the trie and hands back many slots in one call.

This is a debug-namespace method and is available on the Pro tier and above. It is rate limited per tier (5 RPS on Pro, 15 RPS on Business) with a short burst allowance; there is no daily quota.

Examples

curl https://triport.io/sol \
  -X POST -H 'Content-Type: application/json' \
  -H 'Authorization: Bearer <api-key>' \
  -d '{"id":1,"method":"debug_storageRangeAt","params":[],"jsonrpc":"2.0"}'
const res = await fetch("https://triport.io/sol", {
  method: "POST",
  headers: { "Content-Type": "application/json", Authorization: "Bearer <api-key>" },
  body: JSON.stringify({
