Fhenix Confidential ERC20 Callbacks

Overview

...AndCall transfers move tokens and notify the recipient contract atomically — the recipient can accept or reject, enabling staking/swaps/escrow in one tx. Four functions:

confidentialTransferAndCall(address to, InEuint64|euint64 value, bytes data) returns (euint64 transferred);
confidentialTransferFromAndCall(address from, address to, InEuint64|euint64 value, bytes data) returns (euint64 transferred);

(...From... variants require operator permission — see fhenix-confidential-erc20-operators.)
