web3.eth Migration Guide

Defaults and Configs

• In 1.x all default values that returned null now return undefined in 4.x, these include:

  • givenProvider
  • currentProvider
  • web3.eth.defaultAccount
    • 1.x has undefined documented as default, but in implementation it's null

• web3.eth.defaultHardfork default is "london" instead of undefined

  • 1.x has "london" documented as default, but in implementation it's undefined

• web3.eth.defaultChain default is "mainnet" instead of undefined

  • 1.x has "mainnet" documented as default, but in implementation it's undefined

Web3Eth Methods

web3.eth.getHashrate

4.x getHashrate is deprecated, and will be removed in a future release. Please use getHashRate.

web3.eth.getHashrate // -> deprecated, do not use
web3.eth.getHashRate // -> correct usage

web3.eth.getFeeHistory

4.x returns a BigInt for oldestBlock instead of the hex string that's returned in 1.x. And 4.x returns number[], instead of strings[] for baseFeePerGas.

// in 1.x
await web3.eth.getFeeHistory('0x1', 'latest', []);
// {
//     oldestBlock: '0x0',
//     baseFeePerGas: [ '0x3b9aca00', '0x342770c0' ],
//     gasUsedRatio: [ 0 ]
// }

// in 4.x
await web3.eth.getFeeHistory('0x1', 'latest', []);
// {
//     oldestBlock: 0n,
//     baseFeePerGas: [ 1000000000, 875000000 ],
//     gasUsedRatio: [ 0 ]
// }

web3.eth.sendTransaction

• userTransactionObject.chain no longer defaults to "mainnet", will be undefined if not provided
• userTransactionObject.hardfork no longer defaults to "london", will be undefined if not provided

PromiEvents

sending

• In 1.x, the event listener would receive a payload object as an argument. In 4.x, just the sent transaction object is received

// in 1.x
web3.eth.sendTransaction({ ... }).on('sending', (payload) => { ... });
// payload would be:
// {
//   method: 'eth_sendTransaction',
//   params: [
//     {
//       from: '0x6e599da0bff7a6598ac1224e4985430bf16458a4',
//       to: '0x0000000000000000000000000000000000000000',
//       value: '0x1',
//       maxPriorityFeePerGas: '0x9502F900',
//       maxFeePerGas: '0xc3e17d20'
//     }
//   ],
//   callback: undefined
// }

// in 4.x
web3.eth.sendTransaction({ ... }).on('sending', (sendTransactionObject) => { ... });
// sendTransactionObject would be:
// {
//     from: '0x6e599da0bff7a6598ac1224e4985430bf16458a4',
//     to: '0x0000000000000000000000000000000000000000',
//     value: '0x1',
//     gasPrice: '0x77359400',
//     maxPriorityFeePerGas: undefined,
//     maxFeePerGas: undefined
// }

sent

• In 1.x, the event listener would receive a payload object as an argument. In 4.x just the sent transaction object is received

// payload would be:
// {
//   method: 'eth_sendTransaction',
//   params: [

//     gasPrice: '0x77359400',
//     maxPriorityFeePerGas: undefined,
//     maxFeePerGas: undefined
// }
