# Bitcoin Gold Source: https://developers.bitgo.com/docs/bitcoin-gold ## Bitcoin Gold Bitcoin Gold can be accessed with the following coin types: | Environment | Coin Type | Faucet | | :---------------------- | :-------- | :----- | | Bitcoin Gold Production | btg | | ### Explorer https://btgexplorer.com/ ### Fork notes Bitcoin Gold (BTG) forked from the Bitcoin mainnet on October 24, 2017. Bitcoin addresses that had balances on this date kept the same balance within Bitcoin Gold. After this date, blocks and transactions on the BTG fork no longer overlap with Bitcoin. Bitcoin Gold uses a different address format from Bitcoin which protects users from accidentally sending coins to the wrong chain. Bitcoin Gold addresses start with either a `G` or an `A`. As BitGo wallets use multisig addresses, all addresses for BitGo wallets start with an `A`. The Bitcoin Gold fork is replay-safe both ways, meaning that new transaction made on one chain does not occur on the other. ### Dust Threshold A dust threshold is the minimum amount of Bitcoin Gold that you can create in a single output. Bitcoin Gold has a dust threshold of 2730 satoshis. ### Migrated Wallets All BitGo customers using BitGo's Bitcoin wallets on October 24, 2017 had their wallets and keys automatically migrated to the V2 BTG coin type. Users can find migrated wallets by using the [List Wallets](/reference/v2walletlist) API. On the wallet object, there is a `migratedFrom` property that corresponds to the Bitcoin Wallet ID. ### Creating addresses > 📘 **Note:** See section [Address Derivation (BIP-32)](#address-derivation-bip-32) for a table of address types. Bitcoin > Gold defaults to chain 10.
