In the context of Binance Smart Chain (BSC) test, this error can be caused for a few reasons:<\/p>\n<\/p>\n<ul>\n<li><strong> Incorrect sender <\/strong>: The <code>Signtransction method is expected at a valid Ethereum address as a\" sender \". However, if you try to send funds from your private key to an external wallet on BSC Testnet, they may not work.<\/li>\n<\/ul>\n<\/p>\n<ul>\n<li><strong> Invalid contract abi <\/strong>: If the contract abi (the binary interface of the request) is incorrect or incomplete, the \"Signansction\" method can throw an error.<\/li>\n<\/ul>\n<\/p>\n<ul>\n<li><strong> Web3 provider missing <\/strong>: Metask requires a web3 supplier to work correctly.
