signTransaction

Signs tx, returning the fully signed serialized transaction. Note that gasLimit, gasPrice, maxPriorityFeePerGas, maxFeePerGas is a string that can be passed to BigInt (opens in a new tab). eg.

// ✅ valid
const gasPriceString = "9007199254740991"
// ✅ valid
const gasPriceHex = "0x1fffffffffffff"
// ✅ valid
const gasPriceOctal = "0o377777777777777777"
// ❌ invalid
const gasPriceNumber = 9007199254740991
// ❌ invalid
const gasPriceBigInt = 9007199254740991n
// ❌ invalid
const gasPriceBigInt2 = BigInt(9007199254740991)
