Units

Toncoin is divisible by 10^-[9] and the base unit is a nanoton (nton):

1 Ton = 1000000000 nanoton
1 nanoton = 0.000000001 Ton

Toncoin v1 Wallets

Older Toncoin wallets only support the EQ address format and withdrawals to EQ addresses. If the destination address is uninitialized, withdrawing to an EQ address results in a bounce back.

Currently, BitGo uses Toncoin v1 wallets with UQ address format. These wallets support withdrawing to both EQ and UQ addresses.

Toncoin v1 wallets with UQ address format don't require on-chain initialization before they can receive deposits, because these addresses are memoId based. When using these wallets, BitGo recommends using UQ addresses for withdrawing and using memo IDs for depositing.

Note: To enable Toncoin v1 wallets in your enterprise, you may need to contact support@bitgo.com.

Create Address

Note: Receive addresses for Toncoin v1 wallets have the same root address, but use an incremental memo ID as a differentiator.

Note: Toncoin wallets require on-chain initialization before you can use them. Fund a ton wallet with a small amount and make a withdrawal transaction for the wallet to be initialized on chain. BitGo generates EQ addresses for Ton wallets. Any funds sent to this address before initializing will bounce back to the sender. Send the funds to the UQ version of the wallet address to ensure that funds sent to uninitialized wallets don't bounce back. For more info, read https://docs.ton.org/learn/overviews/addresses#bounceable-vs-non-bounceable-addresses

Consolidate Balance

Consolidation isn't required for Toncoin v1 wallets that use memo IDs for receive addresses.

Toncoin is an account-based asset and therefore requires consolidating to the base address in order to use the maximum spendable amount.

BitGo's Toncoin (TON) multisig contract currently only supports one sender and one recipient so the sendMany is not supported.
