Block Explorer API

Internal Transactions (`with-internal`)

BNB Smart Chain (BSC) supports internal transactions (traces). The Transactions API endpoints marked with-traces above accept the with-internal=true query parameter, which includes internal transactions (the value transfers triggered by contract execution that are not recorded as standalone onchain transactions) in the response.

Internal transactions are included in the response by passing with-internal and cost 0.05 credits/item.

Example API Call

Recent transactions with internal transactions

curl -X GET "https://api.covalenthq.com/v1/bsc-mainnet/address/0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045/transactions_v3/?with-internal=true&key=<GOLDRUSH_API_KEY>"

JSON-RPC

BNB Smart Chain (BSC) is available on the GoldRush JSON-RPC service. Point your existing EVM tooling (ethers.js, viem, web3.js, or raw HTTP) at the GoldRush endpoint — the standard eth_*, net_*, web3_*, debug_*, and trace_* methods are supported.
