SerializeErrors

Set of possible errors when serializing a transaction.

RlpEncodeErrors || error{InvalidRecoveryId}

SerializeTransaction

Main function to serialize transactions.

Supports cancun, london, berlin and legacy transaction envelopes.
This uses the underlaying rlp encoding to serialize the transaction and takes an optional Signature in case you want to serialize with the transaction signed.

For cancun transactions with blobs use the serializeCancunTransactionWithBlobs or serializeCancunTransactionWithSidecars functions.\

Example 
const to = try utils.addressToBytes("0xf39Fd6e51aad88F6F4ce6aB8827279cffFb92266");
const base_legacy = try serializeTransaction(testing.allocator, .{
    .legacy = .{
        .nonce = 69,
        .gasPrice = try utils.parseGwei(2),
        .gas = 0,
        .to = to,
        .value = try utils.parseEth(1),
        .data = null,
    },
}, null);
defer testing.allocator.free(base_legacy);

Signature

pub fn serializeTransaction(allocator: Allocator, tx: TransactionEnvelope, sig: ?Signature) SerializeErrors![]u8

SerializeCancunTransaction

Serializes a cancun type transactions without blobs.

Please use serializeCancunTransactionWithSidecars or serializeCancunTransactionWithBlobs if you want to serialize them as a wrapper.

Signature

pub fn serializeCancunTransaction(allocator: Allocator, tx: CancunTransactionEnvelope, sig: ?Signature) SerializeErrors![]u8

SerializeCancunTransactionWithBlobs

Serializes a cancun sidecars into the eip4844 wrapper.

Signature

pub fn serializeCancunTransactionWithBlobs(allocator: Allocator, tx: CancunTransactionEnvelope, sig: ?Signature, blobs: []const Blob, trusted_setup: *KZG4844) ![]u8

SerializeCancunTransactionWithSidecars

Serializes a cancun sidecars into the eip4844 wrapper.

Signature

pub fn serializeCancunTransactionWithSidecars(allocator: Allocator, tx: CancunTransactionEnvelope, sig: ?Signature, sidecars: Sidecars) ![]u8

SerializeTransactionEIP1559

Function to serialize eip1559 transactions. Caller ownes the memory

Signature

pub fn serializeTransactionEIP1559(allocator: Allocator, tx: LondonTransactionEnvelope, sig: ?Signature) SerializeErrors![]u8

SerializeTransactionEIP2930

Function to serialize eip2930 transactions. Caller ownes the memory

Signature

pub fn serializeTransactionEIP2930(allocator: Allocator, tx: BerlinTransactionEnvelope, sig: ?Signature) SerializeErrors![]u8

SerializeTransactionLegacy

Function to serialize legacy transactions. Caller ownes the memory

Signature

pub fn serializeTransactionLegacy(allocator: Allocator, tx: LegacyTransactionEnvelope, sig: ?Signature) SerializeErrors![]u8

PrepareAccessList

Serializes the access list into a slice of tuples of hex values.

Signature

pub fn prepareAccessList(allocator: Allocator, access_list: []const AccessList) Allocator.Error![]const StructToTupleType(AccessList)
