Deploy Contract

DeployContract sends a transaction with no to address and data set to bytecode + ABI-encoded constructor arguments. Equivalent to viem’s deployContract. Requires a Wallet Client with an account.

Import

import (
  "github.com/ChefBingbong/viem-go/actions/wallet"
)

Usage

hash, err := wallet.DeployContract(ctx, walletClient, wallet.DeployContractParameters{
  ABI:      contractABI,
  Bytecode: "0x608060405260405161083e38038061083e833981016040819052610...",
})
if err != nil {
  log.Fatal(err)
}
fmt.Println("Deployed tx:", hash)

// With constructor args
hash, err = wallet.DeployContract(ctx, walletClient, wallet.DeployContractParameters{
  ABI:      contractABI,
  Bytecode: "0x6080604052...",
  Args:     []any{"MyToken", "MTK", uint8(18)},
})

Parameters

Account (optional)

• Type: Account
• Default: client’s default account
• Account to deploy from (must be set on client if omitted).

ABI (required)

• Type: any — []byte, string, or *abi.ABI
• Contract ABI (used to encode constructor args).

Bytecode (required)

• Type: string
• Contract bytecode as hex string (with or without 0x).

Args (optional)

• Type: []any
• Default: nil
• Constructor arguments in order. Omit for no-arg constructor.

Chain / AssertChainID (optional)

• Chain: *chain.Chain — override for chain ID.
• AssertChainID: *bool — default true; assert chain ID matches.

Value (optional)

• Type: *big.Int
• Default: nil
• ETH to send with the deployment (e.g. for contracts that require payment).

DataSuffix (optional)

• Type: string
• Data to append after the deploy payload.

Gas, GasPrice, MaxFeePerGas, MaxPriorityFeePerGas, Nonce, Type (optional)

• Same as for other wallet transactions. Omit for defaults/estimation.

Return type

• DeployContract returns (SendTransactionReturnType, error) — the transaction hash (hex string).

Encode deploy data

Deploy data is bytecode + abi.EncodeConstructor(args...). To build deploy data without sending, use a parsed ABI: concatenate bytecode bytes and parsedABI.EncodeConstructor(args...). See ABI Encoding for EncodeConstructor.
