Describe the Problem

When trying to transfer amount to a contract using transferToContract method that operation returns an error due to usage of toNumber().

I believe this is the place:

fuels-ts/packages/account/src/utils/formatTransferToContractScriptData.ts

Lines 20 to 21 in 24edd5d

	const encoded = numberCoder.encode(new BN(amount).toNumber());
	const scriptData = concat([

Code Snippet

This happens to any value over 100MM.


await wallet
        .transferToContract(CONTRACT_ID, bn.parseUnits('1000000000', 9), ASSET_ID)
        .then((tx) => tx.waitForResult());
