New Blockscout instance: https://mekong.blockscout.com/
Faucet: https://faucet.mekong.ethpandaops.io/
Example of a set code transaction: https://mekong.blockscout.com/tx/0x3e6c0b4776348b1ed573f36edb8ee45862ecb1123d65f64c995a8cb2558e4621
Example of an EOA with code: https://mekong.blockscout.com/address/0xc38c25F8bef91B5C4193d59910Cc02CB99b3B4E8

Set code transactions can be created using the following command:

cast send 0x3451817bb2559A94f65ae59C1e606738c702993E "increment()" --auth 0x3451817bb2559A94f65ae59C1e606738c702993E --rpc-url https://rpc.mekong.ethpandaops.io --private-key {pk} --gas-limit 1000000

The important part here is --auth 0x3451817bb2559A94f65ae59C1e606738c702993E. This transaction, in addition to calling the increment function of the contract 0x3451817bb2559A94f65ae59C1e606738c702993E, turns the sender address into an EOA with code, using the implementation from 0x3451817bb2559A94f65ae59C1e606738c702993E.
