USDT0

Overview

Stable is an EVM-compatible Layer 1 blockchain where USDT0 serves as both the native asset and gas token, eliminating the need for a secondary token to fund transactions. Standard EVM tooling operates without modification on the Stable network. The chain supports ERC-3009 and x402 standards, enabling payment flows including P2P transactions, subscriptions, invoices, and pay-per-call mechanisms.

Units

Each USDT0 is comprised of 1,000,000,000,000,000,000 (10) wei, so not even a single USDT0 can be stored numerically without exceeding the range of JavaScript numbers. Gas fees are denoted in gwei.

1 usdt0 = 10 wei
1 wei = 10 usdt0
1 gwei = 10 usdt0

For that reason, only string balance properties are available, which are balanceString, confirmedBalanceString, and
spendableBalanceString.

Tokens

USDT0 supports the ERC20 token standard. ERC20 tokens on the Stable network are available as BitGo supported assets.

Fees

USDT0 supports EIP-1559 fee pricing. All transaction fees are paid in USDT0, the native asset of the Stable network. The base fee is the minimum price per unit of gas required for a transaction to be included in a block, and must be exceeded by the transaction's specified maximum base fee. A priority fee can be added on top of the base fee to incentivize faster processing.
