Environment Details

  • OS: Linux
  • Node Version: v20.10.0
  • BitGoJS Version: 9.3.0
  • BitGo Environment: XEC mainnet

Description

eCash (XEC) price is extremely low (currently quoted at $0.00005459), and therefore, we need to work with many high values to mount a simple transaction.

When trying to mount a transaction sending the value of 2682085286000000 XEC satoshis (~$1460), the library throws an error because this value is too high, but this value is not an unrealistic number for XEC.

@bitgo/utxo-lib uses bitcoinjs-lib under the hook, and it seems the library has a hard limit of 21 * 1e14 for satoshi values (https://github.com/bitcoinjs/bitcoinjs-lib/blob/master/src/types.js#L97-L101).

Steps to Reproduce

import { UtxoTransactionBuilder } from '@bitgo/utxo-lib/dist/src/bitgo'
import { networks, addressFormat } from '@bitgo/utxo-lib'

const builder = new UtxoTransactionBuilder(networks.ecash)

builder.addOutput(
    addressFormat.toOutputScriptTryFormats('qpxk69p8rehy80k9x6dz9msr8kaugda50q69tp5n4n', networks.ecash), 
    2682085286000000
)

UtxoTransactionBuilder is deprecated and you should use UtxoPsbt instead.

If this problem still occurs with the UtxoPsbt class then please make another issue

@davidkaplanbitgo UtxoPsbt forces the use of BigInt, making everything works as expected. Thanks for the hint!
