Fork notes

Bitcoin Cash (BCH) forked from the Bitcoin mainnet on August 1st, 2017. Bitcoin addresses that had balances on this date kept the same balance within Bitcoin Cash. After this date, blocks and transactions on the BCH fork no longer overlap with Bitcoin.

The Bitcoin Cash fork is replay-safe both ways, meaning that transactions made after August 1st, 2017 on one chain do not occur on the other.

Migrated Wallets

All BitGo customers using our Bitcoin wallets on August 1st, 2017 had their wallets and keys automatically migrated to the V2 BCH coin type.

Users can find migrated wallets by using the List Wallets API. On the wallet object, there is a migratedFrom property that corresponds to the Bitcoin Wallet ID.

To protect against confusion (users sending BCH to BTC addresses or vice versa), migrated wallets may not create new addresses by default. Users should create a new wallet with new keys to ensure all new BCH addresses do not collide with BTC addresses.

Dust Threshold

A dust threshold is the minimum amount of Bitcoin Cash that you can create in a single output. Bitcoin Cash has a dust threshold of 2730 satoshis.

For Bitcoin, BitGo uses a 2-of-3 multisig P2SH scheme, with the keys in the order of User, Backup and BitGo respectively.

Wallet creation can be done in a single line with the help of our SDK.
