Units

The smallest unit of APT (Aptos native coin) is called an "Octa".

1 APT = 10^8 (100,000,000) Octas
1 Octa = 0.00000001 APT

You can pass balances in string or integer format. However, BitGo recommends using string format to ensure values don't exceed the programmable number limit.

Tokens

The Aptos blockchain natively support tokens.

Fees

Every APT transaction-whether involving tokens or native coin, and whether a withdrawal or consolidation—must pay a gas fee. This fee is determined by both the execution & IO costs and storage costs.

APT wallets at BitGo utilize a Gas Tank to cover transaction fees as the designated fee payer. Total fee would be calculated based on the gas used * gas unit price where gas used would always be less than max gas amount which is currently set at 5000.

Create Address

Apt does not require a minimum balance for receiving addresses. However, an additional cost is incurred for on-chain address initialization. The first deposit to a new address includes an extra fee for on-chain account creation.

Consolidate Balance

Consolidation Transfer Fee Source: Aptos Gas Tank

To consolidate your receive address balances into the root address, enter the coin as APT, or an APT Token (apt:usdt).

Estimate Fee

Transaction gas usage can be estimated by simulating it on-chain using the Estimation Gas Fee API, which executes the intended transaction at the blockchain’s current state. The simulation provides an exact gas requirement at that moment, but usage may fluctuate as the chain state changes. Therefore, simulations serve as estimates rather than fixed values.
