Info

description:
Solang currently doesn't support all the seal APIs exposed by the pallet-contract. Provide alternative approaches to make them available in solidity contracts and note the ones whose alternative is not available.

expected results:

  • Create system-contract which would expose the missing APIs to solang-based contracts
  • Document the availability of the said APIs and how to use them.

missing seal APIs:

  • seal_call_chain_extension
  • seal_is_contract
  • seal_caller_is_origin
  • seal_set_code_hash
  • seal_code_hash
  • seal_own_code_hash
  • seal_delegate_call
  • seal_ecdsa_recover
  • seal_ecdsa_to_eth_address
  • seal_contains_storage
