[rpc_endpoints]
kakarot_starknet_sepolia = "https://sepolia-rpc.kakarot.org"

Fork Testing​

$ forge test --fork-url "https://sepolia-rpc.kakarot.org"
# or $ forge test --fork-url kakarot_starknet_sepolia

Config Setting​

[rpc_endpoints]
kakarot_starknet_sepolia = "https://sepolia-rpc.kakarot.org"

[etherscan]
kakarot_starknet_sepolia = { key = "kakarot_starknet_sepolia", chain = 920637907288165, url = "https://api.routescan.io/v2/network/testnet/evm/920637907288165/etherscan" }
