From f7821cfc3d23898c00f39d0c06fd538746673e20 Mon Sep 17 00:00:00 2001 From: saledjenic <86303051+saledjenic@users.noreply.github.com> Date: Tue, 13 Aug 2024 17:26:20 +0200 Subject: [PATCH] fix_: calculating route for erc721 checks one more call if the function doesn't exist on the contract (#5691) Old ERC721 contracts do not have `safeTransferFrom` function, because of that we couldn't estimate the gas and we couldn't resolve the right route. Now we firstly check for `safeTransferFrom` function which is supported by ERC721A contracts and if the contract doesn't have it then we do `transferFrom` function call. Example of ERC721A contract: - https://etherscan.io/address/0x0024bc1035d30ae229a4712189b32131758cb000#code Example of ERC721 contract: -
