To Contract
To use the transfer function we must import it.
use std::asset::transfer;
To transfer some amount of an asset we specify the amount that we would like to transfer, the asset and the ContractId to send it to.
    let amount = 10;
    let address = 0x0000000000000000000000000000000000000000000000000000000000000001;
    let asset = AssetId::base();
    let pool = ContractId::from(address);
    transfer(Identity::ContractId(pool), asset, amount);
