On Ethereum mainnet, is there contract code deployed at address 0x7a250d5630b4cf539739df2c5dacb4c659f2488d at the latest block? Answer true if eth_getCode returns non-empty bytecode, false otherwise.
Answer
true
- latest block
- The canonical head returned by eth_blockNumber at the time of the RPC query; eth_getCode was queried at that block number.
