Inter-contract calls and permissions

Focus: one proxy entry that calls another contract entry after checking call permissions.

Open in Playground 

entry forward_call(target_hash: Hash, entry_id: u16, args: any[]) {
    require(is_contract_callable(target_hash, entry_id), "tx permission blocks call")
 
    let target: Contract = Contract::new(target_hash).expect("target contract not found")
    let deposits: map<Hash, u64> = {}
    target.call(entry_id, args, deposits)
    return 0
}

How it works

• is_contract_callable(target_hash, entry_id) enforces the transaction’s contract-call permission.
• Contract::new(target_hash).expect(...) loads the deployed target contract.
• deposits is empty here so the example stays focused on the call itself.
• target.call(entry_id, args, deposits) invokes the selected target entry.

Invoke this contract with a wallet RPC permission value such as "all" or a specific allowlist. See Permissions for the JSON shape.
